武钢8号高炉冷却壁的水温差一度呈上升趋势,有时水温差达7~8℃,多次出现炉身黏结状况,为此在高炉炉型管理方面进行了探索。8号高炉炉型管理的主要特点是:高炉上部优化布料矩阵,下部缩小风口进风面积,中部控制软水进水温度及水温差,并加强日常高炉操作及特殊炉况的管控。采取这些措施后,实现了对8号高炉炉型的合理控制,保证了炉况稳定顺行。
The water temperature difference at the cooling wall of WISCO No.8 blast furnace once showed an upward trend, sometimes the water temperature difference was between 7 and 8 ℃, and many times the sticking status of the shaft body appeared. Therefore, blast furnace type management was explored. The main features of the blast furnace management on the 8th are as follows: optimize the fabric matrix in the upper part of the blast furnace, reduce the inlet area of the tuyere in the lower part, control the inflow temperature of the soft water and the water temperature difference in the middle part, and strengthen the daily blast furnace operation and special furnace condition control. After taking these measures, it has realized the reasonable control of No.8 blast furnace furnace and ensured the steady and smooth operation of the furnace.
