摘要
针对河北津西正达钢厂加热炉产能不足,炉墙冒火,能耗高,且自动化控制水平落后等一系列问题,对加热炉进行了提产降耗改造。通过选用双蓄热烧嘴、增加炉膛高度,升级自动化控制系统,炉墙、炉顶烧嘴整体浇注等措施,加热能力提高20%,空燃比实现了自动调节,避免了跑火现象,煤气消耗降低了0.15 GJ/t钢,满足了轧钢生产需要。
The heating furnace is reformed in Zhengda Steelworks of Jinxi Group To solve the problems： not enough capacity,flaring up on furnace wall,high energy consumption,and low automatic control level.With measures adopted： selecting double regenerative burner,increasing hearth height,upgrading automatic control system,integrated casting the burners on furnace wall and top,the heating capacity increased by20%,air- fuel ratio can be automatically regulated,flame leak- out avoided,gas consumption reduced by0. 15 GJ /t,the system can meet the requirement of production.
