s no need to con?gure a crane for ladle, thus saving equipment investment Splash shield is applied to reduce equipment damage by splashes Automatic deadlock (precision is ±50mm) is guaranteed after the traversing car is aligned precisely to prevent the traversing car running off from the process of desulphurization 喷吹罐横移车式脱硫方式 该工艺适宜现有厂房车间面积小、布置空间紧张等特殊情况,为老厂改造提供一种独特的脱硫方式. 技术特点 喷吹罐及喷枪布置在横移车上,减小喷吹管道长度,喷吹状态稳定 无需铁水运输车及轨道等设施,节省占地面积 Desulphurization by injection tank traversing car This technology is applicable to special cases that has small area of existing shop building and limited space for layout, providing an unique desulphurization for the revamping of old plant. Technical features Injection tank and lance are arranged on the traversing car, reducing the length of injection pipeline and having a stable injection No facilities like hot metal transportation car and railway are required and the occupied land area is saved
