摘要
以高炉—焦炉混合煤气为燃料,采用空气单预热的高温空气燃烧技术对钢包烘烤器进行蓄热式改造,使用后效果明显。同时通过工业性对比试验,对蓄热式钢包烘烤设备的应用效果进行了研究,并对存在的问题进行了探讨。结果表明,新烤包系统节能效果接近40%,蓄热式钢包烤包装置加热速度快,在线钢包温度能升高240℃以上,钢包温度可达1100℃左右,钢包烘烤质量提高,有利于钢水在钢包内的过程温降减少,并提高生产作业率,降低生产成本。
Using mixture gas of blast furnace-coke oven as fuel, through adopting high temperature air combustion technique, a series of reconstruction for the steel ladle baker were made, and the obvious effects were obtained. Moreover, by means of industrial comparison tests, application effect and present problem for regenerative ladle baker were analyzed. The result makes known that, by comparing with conventional ladle heater, the energy saving effect of the new type of ladle heater was close to 40%, at the same time the heating velocity was quick, and the temperature of on-line steel ladle was able to ascend to 240℃, and the baking quality of steel ladle was improved, which were favorable to decrease the temperature drop of molten steel during the transportation process, increase the manufacture task rate and decrease the production cost.
