在国民经济建设中,钢铁工业是能源消耗的大户,高炉炼铁又是钢铁工业中的能耗大户。为了研究高炉节能,常常需要对高炉进行热平衡测定与计算,以找出高炉节能潜力、方向、措施。 在进行高炉热平衡测定与计算时,下渣温度和铁水温度是最重要的参数之一,在渣量,铁水量一定的条件下,炉渣温度和铁水温度的测定误差会导致全炉热平衡的很大误差,使热平衡的计算结果无法定量地表明能量利用况状。以攀枝花钢铁公司三高炉的热平衡测定结果
In the construction of the national economy, the steel industry is a major source of energy consumption, and blast furnace ironmaking is also a big energy consumer in the steel industry. In order to study the blast furnace energy conservation, it is often necessary to measure and calculate the thermal balance of the blast furnace to find out the potential, direction and measures of blast furnace energy conservation. During the determination and calculation of thermal balance of blast furnace, the temperature of slag and the temperature of hot metal are the most important parameters. Under the conditions of slag quantity and molten iron content, the measurement error of slag temperature and molten iron temperature will lead to great heat balance of the whole furnace Errors make the calculation of heat balance unable to quantify the energy utilization situation. Taking Panzhihua Iron and Steel Company three blast furnace heat balance measurement results
