湘钢金属制品厂自投产以来,钢丝热处理铅槽一直使用木炭粉复盖铅液表层,连续加热炉出口也用木炭粉复盖,其目的是防止铅液和高温状态下的钢丝不至于直接接触空气而被氧化。因为钢丝氧化严重,将给生产工艺带来许多不利,并造成金属的耗费。铅液的氧化,则不汉增加铅耗,而且污染环境。然而,多年的实践证明,用木炭粉作铅
Since its production, the steel wire heat treatment lead tank has been using charcoal powder to cover the lead liquid surface. The continuous heating furnace outlet is also covered with charcoal powder. Its purpose is to prevent the lead liquid and the steel wire under high temperature from coming into direct contact Air is oxidized. Because of serious oxidation of steel wire, will bring many disadvantages to the production process, and lead to the consumption of metal. The oxidation of lead liquid, the Han does not increase the lead consumption, but also pollute the environment. However, many years of practice have proved that using charcoal powder as lead
