Practice of Process for 30t EBT EAF-LF(VD)-CCM at Guiyang Special Steel Co. Ltd

首钢贵阳特殊钢有限责任公司第一炼钢厂通过对30t EBT电弧炉、35t精炼炉、一机一流连铸机生产的操作进行改进,成功实现了电弧炉、精炼炉、连铸机之间的顺利生产,可成功连浇10炉钢。同时对钢包、中间包进行改进和加强钢包的使用管理,在一炉钢的浇铸过程中,将中间包里钢水的温降控制≤15℃,连铸坯质量满足用户要求。

Through improving the operation which to the 30t EBT EAF,35t ladle furnace,the one strand continuous casting machine at No.1 steel plant,Gui Yang Special Steel Co.Ltd of Shou Gang Group,the success achieved electric arc furnace,ladle furnace,continuous casting machine between the smooth production,continuous casting 10 heats can be produced.Meanwhile,ladle,tundish to improvement and strengthen the use of management,in one heat casting process,the temperature drop of molten steel in the tundish control ≤ 15 ℃,the quality of billet met user requirements.
