提高中厚板粗轧高温延伸阶段单道次压下率的方法

Method for improving single-pass reduction rate at moderate-thickness plate rough rolling high-temperature extending stage

Abstract

The invention discloses a method for improving the single-pass reduction rate at a moderate-thickness plate rough rolling high-temperature extending stage. The method comprises a rough rolling reshaping stage, a rough rolling widening stage and a rough rolling high-temperature extending stage, wherein the thickness of a moderate-thickness plate blank after the rough rolling high-temperature extending stage finishes is 1.3-3.0 times of the thickness of a moderate-thickness plate finished product. The method is especially suitable for improvement of the single-pass reduction rate at the moderate-thickness plate rough rolling high-temperature extending stage.
本发明公开了一种提高中厚板粗轧高温延伸阶段单道次压下率的方法,包括粗轧整形阶段、粗轧展宽阶段、粗轧高温延伸阶段,所述粗轧高温延伸阶段结束后的中厚板板坯的厚度为中厚板成品的厚度的1.3~3.0倍。本发明的方法特别适用于提高中厚板粗轧高温延伸阶段单道次压下率。
