台湾中钢公司的粗钢年产量约为600万吨,包括碳素钢和低合金钢型钢和圆钢产品,以及干线管材和压力容器钢板用钢,也生产电器用和深冲用的薄板用钢。为了满足这些钢产品的高质量要求,曾于1982年安装了1号RH真空脱气装置,主要用于提高厚钢板和带钢轧制产品的质量。但从投产以后出现了一系列问题,如抽真空能力不足,往往不能达到厚钢板所规定的氢合量和超低碳钢所要求的碳含量,并且还有
Taiwan’s Sinosteel annual crude steel output of about 6 million tons, including carbon steel and low alloy steel and bar products, as well as the main pipe and pressure vessel steel plate, but also for the production of electrical and deep-drawn sheet with steel. In order to meet the high quality requirements of these steel products, a No. 1 RH vacuum degassing unit was installed in 1982 and was mainly used to improve the quality of rolled steel and strip rolled products. However, there have been a series of problems since its commencement of operation. For example, insufficient capacity of vacuum pumping often fails to meet the required hydrogen content and the carbon content of ultra-low carbon steel required for thick steel plates,
