炼铁过程(包括炼焦和烧结)能耗占钢铁厂的70%。高炉能耗占钢铁厂的55%,其中炼铁燃料比占高炉能耗的85%。因此,钢铁厂的节能必须狠抓降低炼铁焦比。我省1980年上半年重点企业和地方铁厂高炉按折合焦比划分:700公斤以下的有成都钢铁厂(602)、攀钢炼铁厂(609)、威远钢铁厂(653)、峨眉县铁厂(671)、重钢炼铁厂(684)五个厂;800公斤以下的有熊桥铁厂(732)、攀研院410厂(755)、邻水县铁厂(763)、高县铁厂(792)四个厂;800至900公斤的有渠江、后山、清溪、白市驿、灌县、壁山、渠县、赶水、
Ironmaking processes (including coking and sintering) consume about 70% of steel mills. Blast furnace energy consumption accounts for 55% of steel mills, of which ironmaking fuel accounts for 85% of blast furnace energy consumption. Therefore, the energy saving of steel mills must pay close attention to reducing the iron-making coke ratio. In the first half of 1980, the key enterprises in our province and the local ironworks blast furnaces were classified according to the equivalent coke ratio: Chengdu Iron and Steel Plant (602), Panzhihua Iron and Steel (609), Weiyuan Steel (653) and Emei Iron Works (671) and Heavy Steel Ironworks (684); Xiongqiao Ironworks (732), Panzhihua Institute of 410 (755), Linshui Ironworks (763) County Iron Works (792) four plants; 800 to 900 kilograms of Drainage River, after the mountain, Cheonggyecheon, Baekye Station, Irrigation County, Bishan, Drainage County,
