一、概述武钢烧结厂三烧结车间有四台90米~2的烧结机。自1973年投产以来,生产运行稳定,各项生产技术经济指标良好。但烧结机的点火工序,无论是点火质量,还是燃料消耗,均不够理想。加上点火器下部水冷梁高温部分的焊缝常易开裂漏水,时而影响生产的进行。 1979年下半年,烧结厂对旧点火器进行了改造,改变了点火段的结构和烧嘴的配置尺寸,并增设了保温段。炉衬仍为砖砌。它 First, an overview of Wuhan Iron and three sinter plant sintering shop has four 90-m 2 sintering machine. Since it was put into operation in 1973, the production has been running steadily with good technical and economic indicators in all aspects of production. However, the sintering process of ignition, whether it is ignition quality, or fuel consumption, are not ideal. Coupled with the lower part of the lighter water quenching the high temperature part of the weld often cracking leakage, sometimes affecting the production. In the second half of 1979, the sinter factory reformed the old igniter, changed the structure of the ignition section and the configuration size of the burner, and added the insulation section. Lining is still brick. it
