钢铁工业是一个大量消耗能源的部门,其中轧钢生产占钢铁企业总耗能量的1/3,而轧钢加热炉的燃料消耗占轧钢总能耗的70%合理地使用好这部分燃料,以最低的能耗生产出数量多、质量高的合格钢材,已成为冶金工作者十分关注的重大课题。近几年来,我们国家对节约能源极为重视,在轧钢加热炉节约燃料,提高热效率方面做了大量的工作,取得了一定的成效。上钢一厂650轧钢车间加热炉的热效率平均达45.2%,赶上了国际水平。但国内大多数轧钢加热炉由于管理不善、设备不全、工艺落后、缺少计量、操作水平低,造成燃料消耗高,热损失大。热效率一般在30%左右,甚致更低。为了节
The steel industry is a sector that consumes a lot of energy, of which steel production accounts for one-third of the total energy consumption of steel mills, while fuel consumption in rolling mills accounts for 70% of the total energy consumption of rolling. This part of the fuel is used reasonably well, Energy consumption to produce a large number of qualified and high quality steel, metallurgical workers have become very concerned about a major issue. In recent years, our country attaches great importance to energy conservation and has done a great deal of work on fuel saving and thermal efficiency improvement in rolling furnaces and achieved some success. The thermal efficiency of 650 steel rolling plant heating furnace in a steel plant reached an average of 45.2%, to catch up with the international standards. However, due to poor management, incomplete equipment, backward technology, lack of measurement and low operation level, most steel-rolling reheating furnaces cause high fuel consumption and large heat loss. Thermal efficiency is generally around 30%, even lower. For the festival
