摘要: 钢包长水口采用氩封保护浇铸后,可有效降低钢中气体含量。检验结果表明,马钢车轮钢Φ450 mm圆坯的T[O]由未进行氩封保护浇铸时的49.3×10-6降到27.9×10-6,夹杂总量由29.7×10-6降至14.8×10-6,铸坯质量明显改善,车轮的力学性能显著提高。

Abstract: It is available to decrease gas content in steel by long nozzle casting with shielding argon gas. The examination results showed that in comparison without argon gas shielding casting the total oxygen content in φ450 mm round billet of wheel steel produced with shielding argon gas at Maanshan Steel decreased to 27.9×10-6, from original 49.3× 10-6, the total inclusion content in steel decreased to 14.8×10-6 from 29.7×10-6 the quality of cast billet obviously in- creased and the mechanical properties of wheel increased appreciably.
