前言冶金工业是全国的能耗大户,据冶金部能源办公室公布的资料表明,我国冶金工业1979年的能耗达8400万吨标煤,占全国总能耗的14%。在钢铁企业中,轧钢工序的能耗约占企业的能耗的15～20%,而在轧钢工序中,各轧钢加热炉所用的炉用燃料占了该工序能耗的70～80%。所以,抓好轧钢加热炉的节能工作十分重要。我省轧钢 Foreword The metallurgical industry is the major energy consumer in the country. According to the data released by the Metallurgical Energy Office, the metallurgical industry in China consumed 84 million tons of standard coal in 1979, accounting for 14% of the country’s total energy consumption. In the iron and steel industry, the energy consumption of the rolling process accounts for about 15-20% of the energy consumption of the plant. In the rolling process, the furnace fuel used by each rolling and steelmaking furnace accounts for 70-80% of the energy consumption of the process. Therefore, do a good job rolling furnace energy saving is very important. Rolling in our province
