最近,日本一家公司与日本旭硝子公司共同研制成功了控制高炉风口热风流量的陶瓷制动阀。 采用了陶瓷阀能精密地调节高炉内还原气体的流量平衡状况,使之分布均匀,从而达到炉况稳定的效果。 高炉从炉下部近40个风口吹入900～1300℃的热风,利用焦炭燃烧产生的热量和还原气体来熔化还原铁矿石。如果还原气体在炉内分布不均匀,那么装炉的钢铁和焦炭的平衡就会被破坏,不
Recently, a Japanese company and Asahi Glass Co., Ltd. jointly developed a ceramic brake valve to control the blast furnace outlet hot air flow. The use of ceramic valve can be finely adjusted blast furnace reducing gas flow balance, so that the distribution, so as to achieve a stable furnace conditions. The blast furnace blows hot air at a temperature of 900 to 1300 ° C from nearly 40 outlets in the lower part of the furnace to melt the reduced iron ore by utilizing the heat generated by the coke combustion and the reducing gas. If the reducing gas is unevenly distributed in the furnace, the balance of the loaded steel and coke will be destroyed, and not
