1972年9月,我公司在机总厂电炉所用的盛钢桶上进行过滑动水口试验,获得了成功。随后于1973年6月22日在炼钢厂270吨盛钢桶上试验了W—I型滑动水口装置,稍后,又仿鞍钢型滑动水口装置进行了试验。在上述两套滑动机械的基础上,根据试验中存在的问题,结合现场需要,重新设计了W—Ⅱ型预装式滑动水口。经过试验,已取得了较好的效果,准备在1974年全面推广使用。 In September 1972, our company successfully tested the sliding nozzle on the ladle used in the electric furnace of the General Plant. The W-I was subsequently tested on a 270-tonne steel drum at a steel mill on June 22, 1973, and later on, a simulated saddle-type sliding nozzle was tested. Based on the above two sets of sliding machinery, according to the problems existing in the test, combined with the needs of the scene, redesigned W-Ⅱ prefabricated sliding gate. After testing, has achieved good results, ready for the full promotion in 1974.
