Influence of New Zealand Sea Sand Proportioning Ratio on Metallurgical Properties of Vanadium-titanium-bearing Sinter of Cheng Steel

The influences of New Zealand sea sand proportioning ratio on vanadium-titanium-bearing magnetite sintering process and metallurgical properties of sinter were determined.The results show that the vertical sintering speed and utilizing coefficient all increase with increasing sea sand ratio.The grain size distribution of sinter is improved, and mechanical strength and low temperature reduction degradation property don't increase apparently.There are good softening Characteristics in experimental conditions.The composition and structure of sinter are complicated.The sea sand proportioning ratio in the Cheng Steel should be controlled 5%~10%.
