摘 要薄板坯连铸连轧技术是钢铁产业的技术性变革，其所能生产的薄板坯厚度范围越来越广，其还具有生产周期短、成材率高的优点，广泛应用于国民经济的各个领域倍受青睐。薄板坯连铸连轧界普遍关注的问题是如何提高生产的装备水平和技术水平，开更高质量新品种和新工艺。本车间设计为年产 280 万吨薄板坯连铸连轧工艺的车间设计，论文叙述了薄板坯连铸连轧技术的发展进程、技术类型及工艺特点，并将各种典型工艺进行比较。本文选择了 CSP 生产工艺，结合国内外生产技术的特点，制定了车间的产品方案、生产工艺流程和金属平衡表，依据这些要求设计了主辅设备及其生产能力、产品的工艺计算、轧辊和电机的校核、车间平面布置、车间经济技术指标和环境保护等的内容。设计应用氧化保护浇注、液芯压下技术、半无头轧制、铁素体轧制技术和 CVC 轧辊等的先进技术。关键字： CSP；产品工艺；校核；车间设计AbstractThin slab continuous casting and rolling technology is a technical revolution of the iron and steel industry, it can produce the rang of thin slab thickness is growing up widely, and has the advantages of short producing cycle, high yield, wild application of various fields of national economy. Thin slab continuous casting and rolling sector generally focus on the question of how to improve the level of production equipment and technology level, a higher quality of new varieties and new technology.The plant of thin slab continuous casting and rolling is designed for yearly producing 2.8 million tons. The paper describes the development of this technology process, technology type and process characteristics, and all kinds of typical technologies were compared. This design chose the CSP technology, combining with the features of domestic and overseas production technology, and making the products program of plant , production process and metal balance sheet, according to these requirements designed the main and auxiliary equipments, production capacity, process calculation, checking of rolling mill and dynamo, layout, workshop economic and technical index and the environmental protection ,etc.There were oxidation protection casting, under pressure and liquid core technology, half headless rolling, ferrite rolling and CVC roll and so on being applied.Keywords: CSP; Production process; Check; Workshop design目录1 绪论 .- 1 -1.1 薄板坯连铸连轧的发展 .- 1 -1.2 薄板坯连铸连轧的未来发展 .- 2 -1.2.1 各种技术相互渗透，共同发展 .- 3 -1.2.2 新工艺、新技的开发采用 .- 3 -1.2.3 产量、质量逐渐提高 .- 3 -1.3 薄板坯连铸连轧技术特点 .- 4 -2 产品生产方案和金属平衡表 .- 7 -2.1 产品方案的编制 .- 7 -2.2 生产工艺流程 .- 7 -2.3 金属平衡表 .- 7 -3 主要设备选择 .- 9 -3.1 连铸设备选择 .- 9 -3.1.1 连铸机 .- 9 -3.1.2 钢包 .- 9 -3.1.3 钢包回转台 .- 10 -3.1.4 中间包 .- 10 -3.1.5 中间包车 .- 10 -3.1.6 结晶器 .- 10 -3.1.7 二冷段 .- 12 -3.1.8 拉矫机 .- 12 -3.1.9 引锭杆 .- 12 -3.1.10 铸坯切割装置 .- 13 -3.2 轧机 .- 13 -3.2.1 轧机组 .- 13 -3.2.2 轧辊尺寸参数 .- 14 -3.2.3 轧辊材质 .- 16 -4 典型产品工
