Energy-saving Technical Improvement of Thick Plate Mill Heating Furnace
In view of the high energy consumption of heavy plate mill heating furnace in Laiwu Steel,an energy consumption bridge was builsed on thermal balance to diagnose and analyze the furnace and carry out technical transformation.The energy saving technology transformation of the furnace door was carried out on site,and the interlocking procedure of the stepping beam,loading machine and discharging machine was optimized.The technical problem that the thick slab could not be continuously hot loaded due to the high heat feed temperature was solved.The hot feed slab type was expanded through test rolling and the heating control process of the hot feed slab was optimized.After the technical transformation of the thick plate mill heating furnace,the energy saving effect is remarkable,and the coal consumption index is reduced from 1.491 GJ/t to 1.474 GJ/t.
