日本专利№62—78134提出,电炉熔炼过程中产生的钢渣含有许多气体。这样必然导致渣罐总数增加;同时导致凝固时渣组织不密实。为了消除这些缺点,该专利提出往液态渣中加入硅石、氧化皮、铝灰、氯化钠和萤石。由于渣的诸组分相互反应,使渣温度从1400—1550℃上升到1700—1800℃,从而有利于析气。该专利提出,可以普通的河砂或型砂作硅石用;可使用生产过程中(铸、轧、锻等)
Japanese Patent No. 62-78134 proposes that the steel slag produced in the smelting of an electric furnace contains a large amount of gas. This will inevitably lead to an increase in the total number of slag cans; at the same time lead to solidified slag organization is not solid. In order to eliminate these disadvantages, the patent proposes to add silica, scale, aluminum ash, sodium chloride and fluorite to the liquid slag. As the slag components react with each other, the slag temperature is raised from 1400-1550 ° C to 1700-1800 ° C, which facilitates gas evolution. The patent suggests that ordinary sand or sand can be used for silica; can be used in the production process (casting, rolling, forging, etc.)
