一、前言由苏联设计的耐火厂带炉篦子预热机Φ3.6×44.5m回转窑于1956年筹建,准备用于煅烧成球自云石,与平炉炼钢配套,由于种种原因未能按时投产。直至1979年经过多次试验后,将试生产的煅烧成球白云石用于一炼钢补炉,又因生产过程中粉尘太大,加之窑体损坏严重,维修频繁,而被迫停产。1982年9月改为轻烧块状白云石,供二炼钢造渣用。由于没有摸索出合理的生产制度,经常出现三班操作不统一,导致产品质量不稳定,燃料(焦炉煤气)消耗高,如1983年
I. Preface The refractory plant designed by the Soviet Union with grate preheating furnace Φ3.6 × 44.5m rotary kiln was built in 1956 to prepare for calcination into a ball from marble, and open hearth steelmaking, due to various reasons failed to time Put into production. Until 1979 after many tests, the trial production of calcined into a ball dolomite used in a steelmaking furnace, but also because of the production process is too large dust, combined with kiln damage, frequent maintenance, and forced to stop production. In 1982 September changed to light burning massive dolomite, slag for the second steel. Since no reasonable production system has been explored, there are often three operations that are not uniform, leading to unstable product quality and high fuel (coke oven gas) consumption, as in 1983
