TEST OF ALLOYING SMELTING HRB400 EZT1 STEEL WITH SiC TO SUBSTITUTE FERROSILICAON
In Xuan Steel, to reduce cost per ton of steel, improve mechanical property and quality of molten steel, the amount of alloy material:high-quality and low-cost SiC used in smelting of low-alloy steel is increased to substitute the high-cost ferrosilicon and part of recarburization agent.The procedure of smelting HRB400EZT1 steel with 110-ton converter 3#is traced and researched.It is showed that the composition of casting billet is steady and can be controlled, the cost per ton of steel reduced by 0.88 yuan/t, the mechani-cal property of steels improved.The new alloying plan can replaced the traditional one, good economic profit got.
