中板厂有85.4米~2加热炉两座,它为三辊劳特式轧机提供出炉温度高达1250℃的钢坯。前几年由于炉子结构及管理等各方面的原因,炉子热效率低,燃料消耗始终很高,有时高达1.72×10~6千卡/吨钢,经过一年多的努力,煤气单耗已降至0.84×10~6千卡/吨钢(见图1)。 The mill has two 85.4 m ~ 2 heating furnaces, which provide billets with a temperature of up to 1250 ° C for the three-roll Hilti rolling mill. A few years ago due to the furnace structure and management of various reasons, the furnace thermal efficiency is low, the fuel consumption is always high, sometimes up to 1.72 × 10 ~ 6 kcal / ton steel, after more than a year of hard work, gas consumption has dropped to 0.84 × 10 ~ 6 kcal / ton steel (see Figure 1).
