摘要
Abstract
Microstructure and mechanical properties of different heat treatment are analyzed with steel oil storage tanks of a new generation of Xiangtan Steel ,using thermal simulation of welding steel plates of dif-ferent heat treatment processes for large heat input HAZ toughness .The studied shows that:the use of di-rect quenching of DQ steel plate ,the second phase particles than the quantity in the off -line quenching of RQ technology ,more small size ,high heat input after the circulation of small prior austenite grain size;at the same time,hardened steel is onlin ,tempered steel is rapidly heated ,large heat input welding steel best performance .关键词
