我国重点和地方中型钢铁企业现有280个轧钢车间,拥有轧钢加热炉422座。1981年消耗436万吨标准煤,占钢铁企业能源消耗总量的7%,其中有近一半加热炉燃烧重油,年耗油量占钢铁工业烧油总量的35%。三年来,由于突出地抓了轧钢加热炉节能,从而取得了节能增产的显著效果。1981年与1978年相比,重点钢铁企业烧油加热炉的坯材产量,由1,363万吨上升到1,538万吨,增长13%,而消耗重油量由104万吨下降到84万吨,减少20万吨。每吨坯材用
China’s key and local medium-sized iron and steel enterprises existing 280 rolling workshop, with rolling furnace 422. In 1981, it consumed 4.36 million tons of standard coal, accounting for 7% of the total energy consumption of the steel industry. Nearly half of the furnaces used heavy oil for combustion, accounting for 35% of the total annual oil consumption of the steel industry. In the past three years, remarkable achievements have been made in saving energy and increasing production due to the outstanding energy saving in rolling furnaces. Compared with 1978, the output of billets of the oil-fired furnaces of key steel enterprises increased from 13.63 million tons to 15.38 million tons in 1981, up 13%, while the consumption of heavy oil dropped from 1.04 million tons to 840,000 tons, a decrease of 20% Tons of tons.
