西(林)钢集团三座高炉的热风炉都是球式热风炉,原倒球周期为半年,利用春秋检长期休风的时机对热风炉进行倒球。在倒球的过程中需要对渣化粘结的耐火球进行爆破作业,倒球周期短直接影响了热风炉本体的寿命。西钢炼铁总厂采取有效的措施,延长了球式热风炉的倒球周期,将倒球周期控 West (Lin) Steel Group blast furnace blast furnace are three hot blast stove, the original ball rolling period of six months, the use of spring and autumn off the timing of the opportunity to blast the stove. During the process of pouring the ball, the blasting of the slag-bonded refractory ball needs to be carried out. The short period of the ball-feeding has a direct impact on the life of the stove body. Xigang Iron and Steel Plant to take effective measures to extend the ball-hot stove of the ball cycle, the ball-cycle control
