轧钢分厂是我厂自行设计和建造的,其中建有一台炉底面积为19.8×2.55米~2三段式连续加热炉.燃料采用我厂自产的发生炉煤气,发热值为5852千焦/米~3.烧嘴布置如下:加热段顶部设2排6个平焰烧嘴,侧墙两侧共设8个高速烧嘴,下部端墙设3个高速烧嘴,均热段顶部设2个平焰烧嘴,端墙设3个高速烧嘴.高速烧嘴喷出速度为80～100米/秒.当时燃烧能力分配为上加热和下加热各50%.由于上的急,竣工投产后发现该炉存在一些问题:
Rolling plant is designed and built on our own plant, which has built a furnace floor area of 19.8 × 2.55 m ~ 2 three-stage continuous furnace. Fuel produced by our factory gas, heating value of 5852 kilocalorie / M ~ 3. The burner is arranged as follows: 2 rows of 6 flat flame burners are arranged on the top of the heating section, 8 high speed burners are arranged on both sides of the side wall, 3 high speed burners are arranged on the lower end wall, 2 flat-flame burners, 3 high-speed burners on the end wall High-speed burners Spray at speeds of 80 to 100 m / s at which time the combustion capacity was divided by 50% for both upper and lower heating. Put into operation found that the furnace there are some problems:
