年产206万吨短流程带钢车间工艺设计

摘 要

薄板坯连铸连轧是20世纪80年代末、90年代初开发成功的生产热轧板卷的一项短流程工艺，是继氧气转炉炼钢、连续铸钢之后钢铁工业最重要的革命性技术之一。

薄板坯连铸连轧集科学、技术和工程于一体，将热轧板卷的生产在一条短流程的

生产线上完成，充分显示出其先进性和科学性。

世界各国都对此给予了极大关注，使得薄板坯连铸连轧技术近年来又有了突飞猛

进的进展。

与传统生产工艺流程相比，短流程可节约投资、提高成材率、降低生产成本、大

幅度缩减生产周期等。

本设计为年产206万吨薄板坯连铸连轧热轧带钢生产车间设计，论文叙述了薄板

坯连铸连轧技术的类型、市场分析及工艺技术特点，并把各种典型工艺进行了比较。参照国内外企业的技术特点和生产实践，提出了本车间的总体配置方案，设计了主辅设备及其生产能力计算、车间平面布置和起重运输、主要经济技术指标、环境保护以及使用AutoCAD绘制车间平面布置图。并运用VB程序进行了压下规程程序设计和相应的校核等。

本设计选用的是CSP工艺，车间主要布置为：2流50/70 CSP连铸→辊底式均热炉→高压水除鳞→7架CVCplus连轧机→层流冷却→卷取。采用了铁素体轧制技术、半无头轧制技术等新技术。

The Design of a Short Strip Process Plant with an Annual

Output of 2.06 Million tons

Abstract

CSP is the successful development of the production of hot rolled coil in a

shortened process,the oxygen converter steelmaking, continuous casting steel industry after the most important revolutionary technology in the late 1980s and early 1990s. One of the foreign steel major powers have invested a great deal of manpower and resources to the special study.

CSP--science, technology and engineering in one, hot rolled coil production in a

short line to complete the process, fully demonstrated its advanced scientific.

All countries in the world have given a great deal of concern, making CSP

technology a rapid progress in recent years.

Compared with the traditional production process, the CSP process can be

short-saving investment, to become useful raise rates and reduce production costs and significantly reduce the production cycle, and so on.

The design for an annual output of 2.06 million tons of CSP hot-rolled strip steel

production workshop designed paper describes the CSP in the type of technology, market analysis and technology features, and typical of a variety of music comparison. Reference to Magang CSP, the technical characteristics and production practice, raised the overall configuration of the workshop programe,the main design of auxiliary equipment and its production capacity, the plant layout and lifting the transport, mainly economic and technical indicators, environmental protection and the use of AutoCAD Drawing Workshop Layout plans. VB procedures and the use of the order reduction program design and the corresponding check, and so on.

The CSP is the choice of design process, layout for the main workshop: 2-50/70

CSP Casting → Roller-both high-pressure hot water heaters → Descaling → 7-CVCplus rolling mill → laminar cooling → coiling. Use ferrite rolling technology, semi-rolling technology, and other new technologies.
