住友金属工业公司与住金ｍａｎｇｅｍｅｎｔ公司共同开发“电炉高速助燃烧嘴”。在电炉中，因电极位置关系，在炉壁等处会出现废钢难熔的状况。为促进这些冷点的燃烧，从炉壁插入助燃烧嘴，进行火焰喷射。采用传统的烧嘴燃烧火焰速度慢，废钢上的反射热使烧嘴本体熔化，飞... Sumitomo Metal Industries Co., Ltd. and mangement co-development of “high-speed combustion furnace burner.” In the electric furnace, due to the electrode position relationship, there will be in the furnace wall refractory situation scrap. In order to promote the combustion of these cold spots, a combustion burner is inserted from the furnace wall to perform flame spraying. Burning with a traditional burner flame is slow, the heat of reflection on the scrap melting the burner body, fly ...
