The results of theoretical calculation and large-scale production show that the process has the following advantages: stable production; reducing the fuel consumption per ton of steel by 62.5% compared with the conventional method of burning steel; reducing the burning loss by 0.468%; increasing the production capacity of the soaking furnace by one third ; To improve the billet rate of 0.5%; saving initial rolling rolling power consumption of 21.5%; to improve the slab hot charging furnace to improve the hot charging temperature 100 ~ 150 ℃. Through the calculation of the steel ingot theoretical condensation and the production of anatomical steel billet test, Sulfur-stamping method to verify the liquid-core rate, the selected hydraulic core roll rate ≤ 8%. Through testing the surface quality of the liquid core ingot rolled into finished product, its mechanical properties and plasticity are relatively improved; the process performance and the grain size reach the national standard.
