双蓄热步进梁式加热炉控制系统的设计

Design of Control System of Dual Regenerative Walking Beam Reheat Furnace

介绍了天钢高速线材生产线加热炉的工作原理,加热炉控制系统构成、系统配置、网络组态及基础自动化控制。针对新的生产工艺,经过提升改造后的加热炉控制系统实现了烧嘴定时换向自动控制,煤气燃烧自动控制,钢坯步进系统手动和自动两种方式控制,并且在自动模式下能实现步进梁步距补偿,同时实现了L1级坯料跟踪。该控制系统不仅降低了生产成本,而且提高了产品质量,实现了双蓄热加热炉的高效运行。

The paper explains the working principle of the reheat furnace of high speed wire rod production line, Tianjin Iron and Steel Group Company Limited （TISCO）, and the constitution, system arrangement, network configuration and basic automation control of furnace control system. Targeted at the new production process, the upgraded control system achieves the auto control of burner time change-over, the auto control of gas combustion, the manual and automatic control modes of billet walking system, walking beam pace compensation in auto mode and L1 stock tracking. The control system not only reduces production cost, but also improves product quality and achieves the high efficient running of dual regenerative reheat furnace.
