本世纪六十年代,苏联大多数高炉沿用双钟单室炉顶设备。随着炉容扩大及顶压提高,这种设备在布料调节及密封性能方面暴露了很多问题。当时在装料设备改进中,主要采取:(1)研制布料性能较好,且布料漏斗无需密封的新型布料器,提出了既能快速旋转布料,又能按站位布料的双工作制布料器;(2)改 In the 1960s, most Soviet blast furnaces were double-bell single-chamber roof equipment. As furnace capacity increases and jacking pressure increases, such equipment exposes a number of issues in fabric conditioning and sealing performance. At that time, in the improvement of charging equipment, the following main measures were taken: (1) to develop a new type of distributor with better cloth performance and no need to seal the fabric funnel, and put forward a double-work distributor that can rapidly rotate the fabric and cloth at the station ; (2) change
