Study on Casting Speed and the Speed of on-Line Mould Width Adjustment of Slab Continuous Casting

Abstract:

Starting from the analysis of stresses on narrow side shell, based the principle that the stresses of narrow side shell will be less than the hot strength of cast steel grade, the maximum rate of displacement in course of freely bulging under hydrostatic pressure is deduced in this paper. And the speed of width adjustment is set based on which. Meanwhile the strain on wide side shell in width adjustment process is calculated. According to critical strain hypothesis, after investigation a proper casting speed is set to make the strain of wide side shell less than the critical strain and so to ensure the shell thickness in exit of mold meeting with production requirements.
