High temperature fired slide gate plates developed by Zhengzhou Caihua are produced via high speed mixing, high pressure pressing, high temperature firing, vacuum and pressurized pitch impregnation, precise surface grinding and hot stainless steel looping processes. Fired slide gate plates have low impurity and are stable on quality.
High temperature fired slide gate plates developed by Zhengzhou Caihua are produced via high speed mixing, high pressure pressing, high temperature firing, vacuum and pressurized pitch impregnation, precise surface grinding and hot stainless steel looping processes. Fired slide gate plates have low impurity and are stable on quality. Good performance on strength, erosion resistance and thermal shock resistance enables the slide gate plates to cast multiple ladles of molten steel.
