Improvement measures of extending the service life of steel taps of converter

Improvement measures of extending the service life of steel tap hole of converter 1.The life of the skateboard is relatively low. At present, the material of the domestic converter skateboard is mostly aluminum-zirconium carbon. As the material of the ladle skateboard, it has high strength, good thermal shock resistance, and excellent erosion resistance and corrosion resistance; But for the converter skateboard to block slag technically, the service life of the skateboard is relatively low. 2. The life of the tap hole needs to be further improved. The life of the tap hole is one of the important indicators of the converter sliding plate slag blocking technology. The tapping is caused by the frequent direct erosion and violent erosion of high temperature molten steel and high oxidizing slag, and the effect of rapid cold and hot heat. The mouth is easily damaged. The length of its life directly affects the converter smelting cycle, steelmaking productivity and slag ...
