一、前言轧板、大型、热轧三厂计有八座轧钢加热炉,其中轧板厂三座6点供热推钢式加热炉,大型厂二座6点供热推钢式加热炉,热轧厂三座从日本引进的8点供热步进梁式加热炉。目前在武钢所产钢中,有90％要通过轧钢工序,以上三厂能耗约占全公司总能耗的10～12％,而工序能耗中,70～80％是加热炉的燃料消耗。为了摸清武钢用能设备的情况,分析评价用能设备热工指标是否先进,寻找炉子结构、热工操作及管理上存在的问题,公司安排全面开展热平衡测定。现已对大型厂1~#、2~#加热炉、轧板厂3~#加热炉,热轧厂1~#加热炉进行了热平衡测定。通过对四座轧钢加热炉的测定,基本上对各炉能耗去向、炉子热效率、存在问题及节能的主要潜力有了较全面的了解。本文仅就热平衡测定的结果分析武钢轧
First, the introduction of rolling, large, hot-rolled three count there are eight steel rolling furnace, rolling mill three 6-point heating pusher furnace, large factory two 6-point heating pusher furnace, Three hot-rolled plants imported from Japan, 8:00 heating walking beam furnace. At present, 90% of the steel produced by WISCO goes through the rolling process. The energy consumption of the above three plants accounts for 10% to 12% of the total energy consumption of the whole company, and 70% to 80% of the energy consumption of the process is the fuel consumption of the heating furnace . In order to find out the situation of WISCO energy-using equipment, analyze and evaluate whether the thermal indicators of energy-using equipment are advanced, find the problems in the furnace structure, thermal operation and management, the Company arranged to carry out the thermal equilibrium measurement in an all-round way. Has been on the large-scale plant 1 ~ #, 2 ~ # furnace, rolling mill 3 ~ # furnace, hot rolling mill 1 ~ # furnace heat balance measurement. Through the four rolling steel furnace determination, basically the furnace energy consumption to the furnace thermal efficiency, the existing problems and the main potential for energy saving has a more comprehensive understanding. This article only on the results of thermal equilibrium analysis of WISCO rolling
