近年来,我省天然气的产量虽然有所增长,但随着以天然气为原料的五大化工厂相继投产,以及对地质情况的估计不足,造成天然气的供需矛盾愈来愈突出。从长远来看,天然气作为轧钢加热炉的燃料将逐渐紧张,目前有的地区已出现停产待气的情况。要保持和提高轧钢生产能力,有效的措施之一,就是努力降低加热炉的燃耗,提高燃料利用率,大力节约天然气。为了掌握和了解轧钢加热炉当前使用天然气的情况,最近省冶金局组织了对重点钢铁企业部份轧钢加热炉的调查和热工 In recent years, although the output of natural gas in our province has increased, as the five chemical plants with natural gas as their starting materials have been put into operation one after another and the estimation of the geological conditions are not enough, the contradiction between supply and demand of natural gas has become increasingly prominent. In the long run, natural gas will gradually become a strain on the fuel used in steel rolling reheating furnaces. Some regions have already stopped gas production. One of the effective measures to maintain and improve the rolling capacity is to try hard to reduce the burnup of the furnace, increase the fuel utilization and save natural gas. In order to grasp and understand the current use of natural gas furnace heating furnace situation, the provincial Metallurgical Bureau recently organized a survey of some key steel companies rolling furnace heating and thermal
