Abstract

The possibility of ferrite-pearlite banding elimination and obtaining a dispersed and homogeneous ferrite-carbide structure in controlled rolling steels by means of an additional annealing of plates or finished pipes at subcritical temperature values is discussed. It has been found that the regulation of controlled rolling modes and the additional annealing of plates provide not only obtaining a homogeneous structure, but also a significant strengthening of steel with a simultaneous increase in the impact strength.

在亚临界温度范围内通过退火消除可控轧钢中的结构不均匀性

摘要

讨论了通过在亚临界温度下对板或成品管进行额外退火，消除受控轧制钢中铁素体-珠光体带的可能性，并获得分散均匀的铁素体-碳化物结构的可能性。已经发现，控制轧制方式的调节和板的附加退火不仅提供了均匀的结构，而且还显着增强了钢的强度，同时提高了冲击强度。
