摘要

针对316不锈钢中厚板晶粒度控制问题在实验室进行了一系列的轧钢试验

分别对钢坯原始组织状态、总轧制压缩比、单道次变形率3个因素进行分析。试验结果表明

当轧制压缩比超过6时

钢坯原始组织状态对中厚板全厚度晶粒均匀性无明显影响;钢坯加热温度、道次压下量相同时

总压缩比为6生产工艺能够轧制出全厚度晶粒均匀的钢板;当轧制总压缩比为4时

单道次压下率超过30%时

钢板表面晶粒度为2级和7级混晶组织;单道次轧制变形量均小于10%时

即使轧制总压缩比足够大

钢板热轧态晶粒度依然不均匀。

Abstract

The influence of the status of billet steel

rolling compression ratio

deformation rate per pass on grain of 316 austenitic stainless steel medium plate was done in laboratory. The results explained that the total compression ratio is more than 6

the original structure of steel billet has no influence on grain size of hot rolling plate

when the total compression ratio is more than 6

the homogeneous grain in the whole thickness is obtained in condition of same billet steel heating- up temperature and deformation rate per pass. But when the total compression ratio is more than 6

the 2 grade and 7 grade duplex grain are obtained even though the deformation rate per pass is more than 30%

and when the total compression ratio is less than 10%

the grain is heterogeneous even though the total compression ratio is big enough.
