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.
