Cost reduction of alloying element in high strength steel plate by optimization of controlled cooling technology

摘要

Controlled cooling technology is getting more and more attention with the development of thermal-mechanical control process.In the past decade,achieving the given finish cooling temperature was the sole goal for the technology.However,with the research and development of new steels such as super high strength steel,researchers have in recent years realized the determinate effects that different cooling paths have on the finish cooling temperature and paid more attention to the control of the cooling rate.This paper focuses on not only the optimization of the controlled cooling system with high precision and fast cooling rate,but also the research and development of the high strength steel plate with reduced alloying component.
