西德下舍尔登钢厂用滑动水口出钢口使出钢工艺发生了根本的变化。出钢槽和过去一样。一般在出钢后用白云石堵塞。白云石通过一个简单装置用压缩空气一分半钟即可装满(装满量大约为50公斤)。为了使冶炼后出钢无危险,用白云石填满出钢口后,关闭滑动闸门。出钢前拉开闸板,用压缩空气吸管把白云石吸干,出钢口处的渣层用氧气管烧掉。第一只钢包使用行车电子秤按需要量装
West Germany Lower Sheldon steel mills with sliding gate tapping process to make a fundamental change in steel technology. The trough is the same as in the past. After the general use of dolomite tapping block. The dolomite is filled with compressed air in a simple device in about one and a half minutes (a full capacity of about 50 kg). In order to make the smelting of steel without danger, fill the tapping hole with dolomite and close the sliding gate. Open the gate before tapping, use dolomite to suck dry with the compressed air straw, and the slag layer at the tapping hole is burned with oxygen tube. The first ladle use driving electronic scales installed on demand
