摘要
研究了浇注系统结构对10-27t大钢锭成材后探伤合格率的影响。通过改进浇注系统结构，降低浇注过程中的夹渣几率，提高了钢材质量。改进后探伤不合格率由14．6％下降到2．5％，下降了83％。
The paper studied the effect of gating system＇s structure on the qualification rate of the heavy ingots that weigh from 10 to 27 t by ultrasonic testing. The entrapped slag was decreased, and the steel quality was improved by improvement of the gating system. The reject ratio is reduced by 83% from 14.6% to 2,5%,
