Abstract

Abstract

In order to improve the quality of grade E355 slab, based on the existing process conditions numerical simulation, had been conducted to investigate the influences of casting speed, water ratio and superheat on the solidification process of the slab and the position of the soft reduction. Based on the simulation results, theoretically optimal production conditions for this steel grade have been obtained as follows: casting speed is 1.1 m/min, water ratio is 0.66 L/kg, superheat is 10℃, the area of soft reduction is located at a distance of 17.8 m to 21.1 m from the concave surface. According to production data, the soft reduction position should be in segment 7-9.
