PRODUCTION OF HIGH-STRENGTH HOT-ROLLED STEEL TO MAKE ENERGY-ABSORBING AUTOMOTIVE PARTS

摘要

Results are reported from studies performed to help master a new technology for obtaining rolled products of strength class 570 on the 2000 hot-rolling mill at the Magnitogorsk Metallurgical Combine. An analysis is conducted to determine how the formation of the properties of the rolled product is affected by the chemical composition of the steel and the parameters used for hot rolling and accelerated cooling of the strip on the runout roller conveyor of the mill.
