低碳沸腾钢生产的一大质量关键是钢坯表面的气泡暴露,严重者为气泡废品。近几年来,由于“四人帮”的干扰破坏,制度松驰,管理混乱,生产无章可循,致使这一问题更加突出。粉碎“四人帮”以后,狠抓企业整顿,钢的质量迅速提高,气泡废品率显著降低,见图1。为了弄清沸腾钢坯气泡废品的成因与 One of the key issues in the production of low-carbon, boiled steel is the bubble exposure on the surface of the billet. In recent years, the problem has become even more prominent due to the disruption and disruption of the “gang of four”, the slack system, the chaotic management and the fact that production is out of order. After the smashing of the “gang of four,” they pay close attention to the rectification of their enterprises, the quality of steel is rapidly increased, and the rejection rate of air bubbles is significantly reduced, as shown in Figure 1. In order to understand the cause of boiling billet bubble waste
