年产280万吨2250热轧带钢生产线工艺设计 摘 要 随着我国经济的发展，各行业对钢材需求量日趋增加。我国目前钢铁行业发展虽快，但还远远低于发达国家水平。一些高性能的汽车用板，高强度钢板仍有很大一部分需进口。故设计此热轧带钢车间。 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。 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。 为提高设计效率和质量；采用VB语言编制了压下规程程序；采用CAD绘制车间平面布置图。 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  目　　录 1 概 述 1 1.1 热轧板带钢发展史 1 1.1.1国外热轧板带的发展 1 1.1.3热连轧技术发展现状 3 1.1.4我国年产300万吨以上热连轧板带生产状况 3 1.2板带钢生产技术发展趋势 4 1.2.1热轧宽带钢发展方向及市场 4 1.2.2热轧窄带钢发展方向及市场 5 1.3热轧板带生产工艺装备的发展 6 1.3.1除磷技术的发展 6 1.3.2板型、板厚控制技术的发展 6 1.4本设计的目的和意义 6 1.5本设计的相关问题 7 2 车间产品大纲和金属平衡 8 2.1 车间产品大纲 8 2.2 板坯及产品规格 8 2.2.1板
