年产366万吨热轧板带钢车间工艺设计

年产366万吨热轧板带钢车间工艺设计

摘要

随着我国经济的进展，各行业对钢材需求量日趋增加。我国目前钢铁行业进展虽快，但还远远低于发达国家水平。一些高性能的汽车用板，高强度钢板仍有专门大一部分需进口。故设计此热轧带钢车间。

依照设计任务书要求，本车间设计年产量热轧钢卷366万吨；钢种有普碳钢，优质钢和低合金钢；产品规格为1.5~21㎜

×900~1750㎜。

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

设计内容要紧包括：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，环境爱护等。

为提高设计效率和质量；采纳VB语言编制了压下规程程序；采纳CAD绘制车间平面布置图。

关键词：车间设计，热轧带钢，CVC轧机

Annual output of 3.66 million tons of hot rolled flat

steel plant process design

Abstract

With the development of our national economy, various industries of steel demand is increasing day by day. Our country at present the steel industry development is fast, but are still far lower than those of developed countries. Some high-performance cars with board, high strength steel plate is still a big part of the need to import. The reason design strip workshop.

According to the design plan descriptions of the requirement, the annual production workshop design about grades of hot rolled steel coils of 3.66 million tons; A kind of carbon-steel, high-quality steel and low alloy steel; The product specification for 1.5 ~ 21 ㎜ x 900 ~ 1750 ㎜.

This workshop half the conventional rolling process.

All the slab continuous casting slab. To reduce stock specifications, simplify the rolling process, USES the fixed width press. In order to improve the product quality, the frame by finishing all CVC rolling mill.

Design content mainly includes: products, process, equipment selection and production capacity calculation, workshop layout, environment protection, etc.

In order to improve the design efficiency and quality. The VB language under the pressure of rules program; Using CAD drawing workshop floor plan.

Key words:workshop design, strip, CVC rolling mill
