Warehouse building equipment for ferrous and non-ferrous metallurgy

In chemical, petrochemical, oil plants and, generally, in all types of industrial facilities which present a danger of explosion due to the presence of gas in the form of cloud or flammable dust, there are also harsh chemical substances that can be harmful and source of deterioration of electric and non-electric equipment. This short article does not want to describe the characteristics of the materials that can be used in this type of location, but rather to give an overview of the possible applications and contraindications on their use, depending on the type of chemical, petrochemical or oil product treated, processed or stored. Stated that there is a multiplicity of chemical substances and many types of materials that are usually used for the construction of the equipment, in this paper we would like to give a guideline of the possible applications recalling that all the information collected for the preparation of this paper come from reliable sources. Each application has a number of conditions such as exposure time, concentration, temperature etc. For these reasons, Cortem Group recommends to submit to practical tests any materials that might come into contact with chemicals, check the applicability depending on the nature of the chemical, its concentration and its possible emission in free air. Table 1 should be considered as a basic guideline, it will not and cannot be exhaustive for all the possible cases.

Dear readers! Our articles talk about typical ways to solve the issue of renting industrial premises, but each case is unique.

Plasticity - The ability of a material to be change in shape permanently. Tensile Strength — The ability of a material to stretch without breaking or snapping. Malleability - The ability of a material to be reshaped in all directions without cracking. Conductivity - The ability of a material to conduct electricity.

Metals are fused in welding. Metals subjected to a constant load at elevated temperatures will undergo 'creep', a time dependent increase in length. Creep in metals is defined as time dependent plastic deformation at constant stress or load and temperature.

The form of a typical creep curve of strain versus time is shown in Figure Because there are several meth-ods of measuring hardness, the hardness of a material is always specified in terms of the particular test that was used to measure this property. Rockwell, Yickers, or Brinell are some of the methods of testing.

Of these tests, Rockwell is the one most frequently used. Recall that ductility is a measure of how much something deforms plastically before fracture, but just because a material is ductile does not make it tough. A material with high strength and high ductility will have more toughness than a material with low strength and high ductility. Therefore, one way to measure toughness is by calculating the area under the stress strain curve from a tensile test.

Material toughness equates to a slow absorption of energy by the material. Elasticity is the ability of a material to return to its original shape after the load is removed. Theoretically, the elastic limit of a material is the limit to which a material can be loaded and still recover its original shape after the load is removed. By careful alloying of metals, the combination of plasticity and strength is used to manufacture large structural members.

For example, should a member of a bridge structure become over-loaded, plasticity allows the overloaded member to flow allowing the distribution of the load to other parts of the bridge structure.

White cast iron and glass are good examples of brittle material. As an example, you would not choose cast iron for fabricating support beams in a bridge. This property makes it possible for a material to be drawn out into a thin wire. A malleable material is one that can be stamped, hammered, forged, pressed, or rolled into thin sheets. Corrosion, sometimes called oxidation, is illustrated by the rusting of iron. The last metal or alloy in each column exhibits the least. In the column labelled "Toughness," note that iron is not as tough as copper or nickel; however, it is tougher than magnesium, zinc, and aluminium.

In the column labelled "Ductility," iron exhibits a reasonable amount of ductility; however, in the columns labelled "Malleability" and "Brittleness," it is last. A few examples include wrought iron, cast iron, carbon steels, alloy steels, and tool steels. Normally, ferrous metals are magnetic and nonferrous metals are nonmagnetic. Iron is produced by reducing iron ore to pig iron through the use of a blast furnace.

From pig iron many other types of iron and steel are produced by the addition or deletion of carbon and alloys. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil. The difference comes from the properties controlled during the manufacturing process. Alloy-ing it with nickel, chromium, molybdenum, silicon, or vanadium improves toughness, tensile strength, and hardness. A malleable cast iron is produced through a prolonged annealing process.

The chemical analysis 'and properties of this iron and the lowest carbon steel are practically the same. The primary use for ingot iron is for galvanized and enameled sheet. When steel was developed, it revolutionized the American iron industry. With it came skyscrapers, stronger and longer bridges, and railroad tracks that did not collapse.

Steel is manufactured from pig iron by decreasing the amount of carbon and other impurities and adding specific amounts of alloying elements. In steel manufacturing, controlled amounts of alloying elements are added during the molten stage to produce the desired composition. If there is free graphite then it is cast iron, otherwise it is steel.

STEEL It does not respond to any form of heat treating, except case hardening. When welding, spe-cial electrodes must be used along with preheating and stress- relieving procedures to prevent cracks in the weld areas. These steels are used for dies, cutting tools, mill tools, railroad car wheels, chisels, knives, and so on. Each series includes several types of steel with different characteristics.

This type of steel is very tough and ductile in the welded condition; therefore, it is ideal for welding and requires no annealing under normal atmospheric conditions. The most well- known types of steel in this series are the and The chromium nickel steels are the most widely used and are normally nonmagnetic.

Alloy steels may be produced in structural sections, sheets, plates, and bars for use in the "as-rolled" condition.

Nickel Steel 2. Chromium Steel 3. Chrome Vanadium Steel 4. Tungsten Steel 5. Manganese Steel The nickel increases the strength and toughness of these steels. Nickel steel is used in the manufac-ture of aircraft parts, such as propellers and airframe support members. These steels contain between 0. Some of these steels are so highly resistant to wear that they are used for the races and balls in antifriction bearings. Chro-mium steels are highly resistant to corrosion and to scale.

Steels of this type contain from 0. Common uses are for crankshafts, gears, axles, and other items that require high strength. This steel is also used in the manufacture of high-quality hand tools, such as wrenches and sockets. This is the ability to continue to cut after it becomes red-hot. Cutting Wheel Small amounts of manganese produce strong, free-machining steels.

Railroad tracks, for example, are made with steel that contains manganese The process is named after its inventor, Henry Bessemer, who took out a patent on the process in

Published on December 12, November 26, Non-ferrous metals are those metals that do not contain iron as a principle ingredient they can contain a small percentage. The production of non-ferrous metals pre dates the Middle Ages. Records show the mining of lead and copper for centuries, while tin was extracted during the Roman era. The industrial revolution led to increased use of nonferrous metals. With the growth in the industry, interest increased in production of each metal as well as re-smelting scrap metals.

Metal Production - Iron, Steel & Non Ferrous Metals

Ferrous metals and alloys contain iron; non-ferrous materials do not. Luckily, there are several other factors that differentiate the two. These metals are primarily used for their tensile strength and durability, especially mild steel which helps hold up the tallest skyscrapers and the longest bridges in the world. You can also find ferrous metals in housing construction, industrial containers, large-scale piping, automobiles, rails for railroad and transportation, most of tools and hardware you use around the house, and the knives you cook with at home. Due to the high amounts of carbon used when creating them, most ferrous metals and alloys are vulnerable to rust when exposed to the elements.

Within the metal industry, the production, processing and trade of NE-metals or alloys and semi-finished products made of NE-metals play a special role. Thanks to their properties, non-ferrous metals and their alloys are used in particular in the machine, aircraft and vehicle construction fields, in the construction industry and in electrical and electronic equipment.

In metallurgy , a non-ferrous metal is a metal, including alloys , that does not contain iron ferrite in appreciable amounts. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight e. For example, bauxite is used as flux for blast furnaces , while others such as wolframite , pyrolusite and chromite are used in making ferrous alloys. Important non-ferrous metals include aluminium, copper, lead , nickel , tin , titanium and zinc, and alloys such as brass. Precious metals such as gold , silver and platinum and exotic or rare metals such as cobalt , mercury , tungsten , beryllium , bismuth , cerium , cadmium , niobium , indium , gallium , germanium , lithium , selenium , tantalum , tellurium , vanadium , and zirconium are also non-ferrous. Due to their extensive use, non-ferrous scrap metals are usually recycled. The secondary materials in scrap are vital to the metallurgy industry, as the production of new metals often needs them. Non-ferrous metals were the first metals used by humans for metallurgy. Gold, silver and copper existed in their native crystalline yet metallic form. These metals, though rare, could be found in quantities sufficient to attract the attention of humans.

What is a non-ferrous detector and a ferrous detector?

JGC handles non-ferrous metal refining plant construction projects based on its broad engineering technologies cultivated through designing and building chemical plants, nuclear-related facilities, and other facilities. In particular, JGC possesses global top-class technology expertise and experience in designing and building plants for "wet smelting" which is at the center of interest because it addresses the problems posed due to the need to exploit lower-rank ore deposits, increased sulfur and other impurities in ores, and overall efforts to reduce the environmental burden resulting from processing these ores. Securing non-ferrous metals, such as copper, nickel, and rare metals, is growing in importance worldwide amid robust demand from emerging countries.

Laser marking for traceability on metal surfaces has become a significant new requirement for producers. The technology was introduced to the aluminum sector a few years ago.

The Difference Between Ferrous and Non-Ferrous Metals

When the earth was formed the molten mass contained the many different metals which today we extract and use in huge quantities. Most of the metals combined with rock when molten, to form metallic ores. The most common of these are bauxite, from which aluminium is extracted, and iron ore from which iron is extracted. More than seventy different metals are extracted and used in the manufacturing industries today. Some, like copper and lead for example, can be used in their pure state, to take advantage of their natural properties.

Soaps are cleaning agents that are usually made by reacting alkali e. A soap is a salt of a compound known as a fatty acid. A soap molecule consists of a long hydrocarbon chain composed of carbons and hydrogens with a carboxylic acid group on one end which is ionic bonded to a metalion, usually a sodium or potassium. The hydrocarbon end is nonpolar and is soluble in nonpolar substances such as fats and oils , and the ionic end the salt of a carboxylic acid is soluble in water.

Here we have gathered some useful information to help you identify the most common types of scrap metal and determine their value. Ferrous metals usually contain iron.

It took millions of years before thinking humans walked the Earth but only a few thousands for them to dominate and modernize it. The discovery of metals literally jumpstarted the industrial age. Of the plethora of applications metals are used for, construction remains its largest beneficiary.
