现代高炉不断向着现代化、大型化方向发展液压传动,微机控制涉及此领域后,更使高炉设备面目一新。但对炉前铁口,渣口的设备却没什么改观,使得炉前操作与先进高炉冶炼不相适应。特别是无水炮泥、优质耐火材料的使用,更增加开铁口的难度与强度;新型开铁口机的研制,实为急待解决的 Modern blast furnace constantly toward the modernization, large-scale development of hydraulic power transmission, computer control in this area, but also make the blast furnace equipment a new look. However, the front of the furnace mouth, slag mouth of the equipment but nothing changed, making the furnace operation and advanced blast furnace smelting incompatible. Especially the use of anhydrous stemming and high-quality refractories increases the difficulty and strength of opening the iron mouth. The development of a new type of iron turning machine is in urgent need of solution
