HOT ROLLING
Stainless steel is a special metal alloy. At the first process of production, the steel is melted to a liquid form and then cast into platinum (thick plate) if flat plates or rolled products are required or die cast (rods) if long rods or profiles are required.
Other producing processes follow depending on the status of the cooled final product. For flat products, platinum is first reheated in furnaces under 1000-1100 degrees and passed through the hot rolling mills to obtain the thickness required before the cold rolling process. The dirt/oxide layer on the material is cleaned with acid or surface-ground if necessary. These rolls are annealed with various technological systems depending on their quality to obtain the required mechanical and physical properties and form the crystal structures. Chromium and nickel alloy elements are subjected to instantaneous cooling with cold water to transform their crystal structure into austenitic crystals. These rolls of approximately 20 to 24 tons are conveyed to cold rolling unit in accordance with the below procedures.
