【Abstract】 The main failure forms of fire bars in cycle type sintering machine are burning erosion and fracture. In order to improve the strength and anti corrosion properties of furnace fire bars, their chemical composition are optimized, alloy elements of Ni, Mo and V are added into steel. The fire bars with heat resisting and high toughness and strength are developed. The service life of high Cr alloy fire bars is increased by a factor of 4 improved 3 times than that of heat resisting nodular cast iron pieces. The cost is reduced by above 20%, the machine halt frequency are decreased and the work intensity can be reduced.更多还原
