Austenitic stainless steel (201, 202, 301, 304, 316) is non-magnetic or weakly magnetic, martensitic or ferritic stainless steel (430, 420, 410) is magnetic. Most of the stainless steel usually used as decorative pipe plate is austenitic, generally speaking, is non-magnetic or weakly magnetic, due to smelting composition bias or improper…
Continuous casting electromagnetic stirringㄗbrief EMSㄘ technology refers to the electromagnetic metallurgy technology, which is used to improve the quality of continuous casting billets by installing different types of EMS at different locations of the CCM. The generated electromagnetic force to enhance the flow of the liquid, thus change the heat transfer condition during the solidification of…
Q: Why does the molten steel need to be deoxidized? A: If the molten steel is not deoxidized, the continuous casting billet will not have the correct solidification structure. High oxygen content in steel will also produce subcutaneous bubbles, loosening and other defects, and intensify the harmful effects of sulfur.…

DC EAF and AC EAF steelmaking process has different features The magnetic field force generated by the energized in DC EAF has strong stirring ability than the AC EAF, and DC EAF decarburization, dephosphorization, degassing reaction is faster than the AC EAF, more conducive to the operation. Because the desulfurization…
After the reheating furnace ignited and runs successfully, we have another good news from the project site. Hot commissioning of wire rod gains success, the local team and SME site team share this moment of joy together. When the laying head releases the first qualified wire rod Ø5.5mm, everybody at the…
Steel is as base and skeleton of industry and can be repeated recycling. Most people have impressions of heavy, tough and solid. Actually, the most thin stainless steel looks almost thinner than a sheet of A4 page, and easily can be torn off by hands. Its hardness of this steel…
