Guidelines for fabricating and processing plate steel Page 2 Plate chemistry Steel is essentially a combination of iron and carbon. Primary Steel Making Steelmaking starts with melting the raw inputs of iron ore, coke (produced by carbonisation of coking coal) and limestone together in a blast furnace. Metal stamping, also referred to as pressing, is a low-cost high-speed manufacturing process that can produce a high volumeof identical metal components. This paper presents a novel incremental bending process to obtain complicated curved steel plates by a series of sequential and layered punches. The goal of this process is to obtain steel plate thicknesses, widths and lengths that are available from all four steel plate … Cold rolled steel is essentially hot rolled steel that has had further processing. The resulting red hot molten iron contains 4-4.5% carbon and other impurities that make it brittle. Cold rolling increases the yield strength and hardness of a metal by introducing defects into the metal’s crystal structure. Mild and carbon steel plates are produced by mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel’s recrystallization temperature. Our company has a special … Enter the email address you signed up with and we'll email you a reset link. The cold rolled process creates a finished product that is more precise dimensionally than a hot rolled product. Optimization of the coating process 3.
