高压操作不仅能有效提高冶炼强度,而且能有效降低焦比,炉顶压力每提高0.1kg/cm~2,燃耗降低1～2％,炉容愈大,炉顶压力应愈高,高炉强化程度愈高,愈需要实行高压操作,高压强化的实质在于增加气体的密度以增加其质量流量,它可用高压特性曲线来描述,高压节能归结为抑制了直接还原,发展了间接还原,改善了顺行和煤气利用,但随着炉顶压力水平提高,燃耗降低幅度减小。
High pressure operation can not only effectively improve the smelting strength, but also effectively reduce the coke ratio. When the pressure in the top of the furnace is increased by 0.1 kg / cm ~ 2 and the fuel consumption is reduced by 1 ~ 2%, the higher the furnace capacity, The higher the degree, the higher the need to implement high-pressure operation, the essence of high-pressure intensification is to increase the density of gas to increase its mass flow, it can be described by the high-pressure characteristics curve, high-pressure energy savings due to the suppression of direct reduction, the development of indirect reduction, improved Shun Line and gas utilization, but with the pressure level of the top of the furnace to reduce the reduction of fuel consumption.
