Chengde Iron & Steel sintering production was mainly vanadium-titanium magnetite concentrate for the iron materials, But the finished sinter strength is low, RDI is serious。To solve this problem, this paper studied the material function、sintering process、sinter performance.then we can get that when the Sea-sand/s ratio is 0%, Montenegro, vanadium powder/s ratio is 14%, ordinary powder/s ratio is 20%, steel slag/s ratio is 1% , the ore is best.it provide theoretical basis for chenggang to improve the sinter quality .
