(三) 热工操作 1.烧钢方法是热工操作的核心,一般通过温度制度和供热制度来表现其特征。 (1) 高烧法(即强化加热)。我国目前的烧钢方法,除高碳钢、合金钢外,普遍采用的是高烧法。钢锭装炉后以最大热负荷使炉温升到超过出炉时炉温20～50℃,即所谓高位设定,当钢锭加热到表面铁皮即将熔化之前,立即把炉温降到出钢时水平,即所谓低位设定,一直保温到出钢。这种方法的
(C) thermal operation 1. Burn the steel method is the core of thermal operation, generally through the temperature system and the heating system to show its characteristics. (1) high fever method (that is, enhanced heating). China’s current method of burning steel, in addition to high-carbon steel, alloy steel, the commonly used method is high fever. After the ingot furnace is installed, the maximum heat load causes the furnace temperature to rise beyond the furnace temperature of 20 to 50 DEG C, that is, the so-called high setting. Immediately before the ingot is heated to the surface of the metal sheet to be melted, the temperature of the ingot is immediately lowered to the level of tapping, The so-called low setting, has been insulated to tapping. This method
