美国雷诺铝公司在工业生产中采用了氯、一氧化碳和氮的混合气体。它可与氯气匹敌。用氯气精炼液体铝除去非金属悬浮颗粒和氢气,是多年来铝工业中采用的一个实用方法。没有别的气体能一贯保证有如氯气所提供的可靠性,尤其是对于内部质量要求高的产品。单用氯不能保证在所有时候得到某些顾主所需要的质量。今天,在多数 American Renault aluminum companies in the industrial production of chlorine, carbon monoxide and nitrogen mixed gas. It is comparable to chlorine. The use of chlorine to purify liquid aluminum to remove non-metallic suspended particles and hydrogen is a practical method used in the aluminum industry for many years. No other gas can consistently guarantee the reliability offered by chlorine, especially for products with high internal quality requirements. The use of chlorine alone does not guarantee the quality required by some clients at all times. Today, in the majority
