“ZF”法是我国自行研制的一种浇铸沸腾钢锭的新工艺。采用这种方法,可提高钢锭成坯率3～4％,提高钢锭平均装炉温度150～180℃,平均入炉温度可达1006.2℃,是一种保证液芯加热和液芯轧制的有效途径之一。由于装炉温度提高,还可降低燃料消耗40％,降低烧损0.5～0.7％,使均热炉生产能力提高30％。这种方法可以实现镇静钢、沸腾钢共用一种钢锭模,钢锭质量合格率也比传统方法提高0.44％,达到99.66％。目前“ZF”法已在我国鞍钢一、二炼钢厂、攀钢等厂推广,已铸出沸腾钢锭2×10~6t以上,吨钢经济效益可达5.82￥/t。目前“ZF”法已被列为全国重点推广项目之一。
“ZF” method is our own developed a new method of casting ingot ingot. By this method, the ingot ingot can be increased by 3 to 4%, the average loading temperature of the ingot can be increased from 150 to 180 DEG C and the average ingress temperature can reach 1006.2 DEG C, which is an effective way to ensure the liquid core heating and liquid core rolling. One of the ways. As the furnace temperature increases, but also reduce fuel consumption by 40%, reduce the burning of 0.5 to 0.7%, so that the soaking furnace production capacity increased by 30%. This method can achieve a stable steel, boiling steel share a steel ingot mold, ingot quality pass rate than the traditional method to improve 0.44%, reaching 99.66%. At present, the “ZF” law has been promoted in China’s No.1 and No.2 steel mills and the Panzhihua Iron and Steel Plant. Cast iron ingot boils over 2 × 10 ~ 6t and the economic benefit per ton of steel reaches 5.82 ¥ / t. At present, “ZF” law has been listed as one of the national key promotion projects.
