在轧钢厂的能量消耗中,加热炉热耗占有最大的比例。所以,如何改造现有加热炉以降低能耗,是轧钢厂节能的重要课题。这方面国外已做了大量工作,取得了显著的节能效果。解决这个问题从两方面入手,一是改进操作方法,二是改进设备。本文主要介绍设备改造方法。设备改造的着眼点是充分利用废气中的余热和防止热量散失,下面将这一情况逐一介绍。
In the steel mill energy consumption, furnace heat consumption accounted for the largest proportion. Therefore, how to transform the existing heating furnace to reduce energy consumption is an important issue for energy conservation in rolling mills. In this regard, a great deal of work has been done abroad and remarkable energy-saving effect has been achieved. Solve this problem from two aspects, one is to improve the operation method, the second is to improve the equipment. This article describes the method of equipment modification. The focus of equipment reform is to make full use of exhaust heat and prevent heat loss, the following one by one this situation.
