摘要
作者利用热模拟试验机进行不同条件下的单阶段和多阶段高温压缩变形试验，对热轧管线钢的控制轧制规程及相应的奥氏体行为特性进行了研究。这对制定。
Near net shape casting is a forward subject in the current study of metallurgy science.This paper introduces the present developments of the technology and its possible trend in the future.Of the study in the field,Americans take interest in single roll casting and Japanese weight twin,while western European strive to develop new type of the caster by improving the structure and function of the freezer.
