A standard for testing ike resisting ability of refractory to CO corrosion with mixed gas instead of pure CO has also been discussed. The results show : the addition of hydrogen accelerates the CO corrosion on gunning material ; the same results has been reached with the CO , 200 hours and CO 95 % + H2 5 % , 24 hours. It is reasonable to use CO 95% + H25% , 24 hours instead of pure CO, 200 hours to lest the resisting ability of refractory to carbon monoxide corrosion.展开更多

It has been found that both of adhesion and slag-corrosion resistance are good for the gunning material. It was simple and fiexible to repair by machine. The furnace life can be prolonged to more than two-fold after using the gunning material.展开更多
