首钢多年来一直使用电动开铁口机,虽有几次改进,但仍不能满足炉前操作的需要。首钢设计总院经过两年多的研究、实验、摸索,终于自行设计出SGK—Ⅰ型全液压开铁口机,并成功地应用于首钢新3号高炉(2536m~3)。
Shougang has been using electric iron machine for many years, although several improvements, but still can not meet the needs of the furnace operation. After more than two years of research, experiment and exploration, Shougang Design Institute finally designed SGK-Ⅰ fully hydraulic iron turning machine and successfully applied it to Shougang No.3 blast furnace (2536m ~ 3).
