强化冲天炉熔化的最有效方法之一是使用双排风口,两排风口的间隔为800～900mm。苏联农业机械制造研究院用此法改建了XepcoH联合收割机厂铸铁车间的冲天炉,既节约了焦炭,又提高了铁水温度。冲天炉的工艺设计参数如附表。空气由一台鼓风机送入风口,但每排风口各有自己的集气管和调节流量用的闸板。两排风口间空气流量比例的调节系统中装有全套仪表。进行了14次试验。焦炭用量分布的频率曲线、铁水温度曲线和焦炭燃烧率如附图所示。图中1为单排风口;2为双排风口,H=550mm;3为双排风口,
One of the most effective ways to enhance cupola melting is to use a double vent, with two vents spaced 800-900 mm apart. The Soviet Union’s Agricultural Machinery Manufacturing Research Institute converted a cupola at the XepcoH Combine Harvester’s cast iron plant to save coke and raise the hot metal temperature. Cupola process design parameters such as schedule. The air is fed into the tuyere by a blower, but each tuyere has its own manifold and flowgate. Air flow between the two vents ratio adjustment system is equipped with a full set of instruments. 14 tests were conducted. The frequency distribution of coke consumption curve, hot metal temperature curve and coke combustion rate as shown in the figure.
