一、前言为解决36m~2高炉的燃料问题,圻钢在毛主席“独立自主,自力更生”方针的指引下,曾于1972年建成热压煤球工艺,并用自产的热压煤球按50%、75%和100%比例进行三次高炉冶炼试验,获得了可喜的成绩,但在全球冶炼时,暴露了因强度较低,导致炉况不够顺利的弱点,感到有进一步提高煤球强度的必要。74年圻钢在批林批孔运动的推动下,在各级领导的关怀与支持下,坚持继续革命,针对上述问题于11月末建成了热压煤球焙烧炉。经过焙烧的煤球(即焦球)强度显著提高,有可能满足小高炉冶炼的需要。这次试验的目的就是为了进一步验证焦球代替焦炭作为高炉燃料
I. Introduction In order to solve the fuel problem of 36m ~ 2 blast furnaces, under the guidance of Chairman Mao ’s principle of “independence and self-reliance”, the company built the hot briquette process in 1972 and used its own hot briquettes at 50% , 75% and 100% for blast furnace smelting test three times, and achieved gratifying results. However, in global smelting, the weakness resulting from the lower strength and the unfavorable furnace conditions were exposed. It is necessary to further improve the strength of the briquettes. In 1974, with the care and support of leaders at all levels, with the support of the pro-Lin campaign, the steel industry insisted on continuing the revolution and built a hot briquette roaster in response to the above-mentioned problems in late November. After bake briquettes (that is, coke ball) strength was significantly improved, it is possible to meet the needs of a small blast furnace smelting. The purpose of this test is to further verify that coke balls replace the coke as a blast furnace fuel
