连铸技术在钢铁工业的应用,近几年来得到很快的发展.国外连铸技术的提高主要表现在:1.连铸机生产能力的提高;2.连铸设备设计及制造技术的改进;3.铸坯质量的提高;4.浇铸钢种的扩大;5.自动化及过程控制技术的应用.还发展了一些新型连铸机,如离心连铸机、水平连铸机、带式连铸机和轮带式连铸机等.我国从1957年就开始研究连铸技术.1960年试验成功了弧形连铸机.1964年建成了第一台弧形板坯连铸机.随着我国钢铁工业的发展,连铸技术必将得到相应的发展.我国现有的一些小型轧机需要50~70毫米小方坯,因而提出了发展高速小方坯连铸机解决供坯的问题.

There are three curved-type slab continuous casters,5m in curvature radius,in No.3 Conver-ter Workshop of Shanghai No.1 Iron and Steel Works.These casters are used to produce slabs(150×900-1050mm) supplied for Steel Plate Workshop as primary material of plate.These three cast-ers are characterized by the small curvature radius,simple and crude equipment,and less invest-ment.Besides providing you with the general information of the equipment of continuous casting,technical and operating process,this article will...

There are three curved-type slab continuous casters,5m in curvature radius,in No.3 Conver-ter Workshop of Shanghai No.1 Iron and Steel Works.These casters are used to produce slabs(150×900-1050mm) supplied for Steel Plate Workshop as primary material of plate.These three cast-ers are characterized by the small curvature radius,simple and crude equipment,and less invest-ment.Besides providing you with the general information of the equipment of continuous casting,technical and operating process,this article will describe in detail some technical improving meas-ures that have been taken to suit such simple and crude casters.

上海第一钢铁厂第三转炉炼钢车间现有曲率半径5m的全弧形板坯连铸机3台,用以生产150×900~1050mm的板坯,作为该厂钢板车间的坯料。这3台板坯连铸机的特点是:曲率半径偏小,设备简陋和投资很少。本文除一般叙述该厂连铸生产的设备、工艺和操作情况外,将着重介绍为适应这种简陋的铸机,在生产技术上所采取的一些改进措施。

This paper introduces the electrical equipments for modern slab caster, produced byYas-kawa Japan. It includes main control equipment, operating monitor system, data transmission system and drive system. These equipments have been used to No. land No.2 caster of Bao-shan Iron and Steel Company in Shanghai.
