年产500万吨热连轧带钢车间

摘 要

本文以包钢稀土钢板材公司2250热连轧带钢车间为依据,在包头地区建立一个热连轧带钢车间,根据设计任务书要求,本车间设计年产量热轧钢卷500万t;钢种有普碳钢,优质钢和低合金钢;产品规格为1.2~25.4×830~2130mm。

设计内容主要包括:产品方案,工艺流程,设备选择及生产能力计算,车间平面布置,环境保护等。

本车间采用常规半连轧工艺。板坯全部采用连铸坯。为减少坯料规格,简化轧制程序,采用定宽压力机。为提高产品质量,精轧机各架全采用CVC轧机。

采用CAD绘制车间平面布置图。

关键词:热轧带钢;半连续;轧制温度;轧制压力;轧制速度。

Annual output of 5 million tons of strip steel workshop

Abstract

In Baotou rare earth steel company on the basis of 2250 continuous strip steel workshop in the Baotou region to establish a continuous strip steel workshop, according to the design specification requirements, this workshop design annual production of 5 million t hot rolled steel coils; Steel grade of carbon-steel, high-quality steel and low alloy steel; Product specification is 1.2 ~ 25.4 x 830 ~ 2130 mm.

Design content mainly includes: product scheme, process flow, equipment selection, calculation of production capacity, the workshop layout, environmental protection, etc.

This workshop USES conventional half and rolling process. The slab are all made of casting billet. To reduce billet specifications, simplify the process of rolling, adopt fixed width press. In order to improve the quality of our products and finishing mill adopts the frame of CVC mill.

Using CAD drawing workshop layout.

Key words: Hot rolled strip steel workshop design; Semi-continuous; Rolling temperature; The rolling pressure; The speed of rolling
