中间包覆盖剂

本产品主要用于连铸时覆盖在中间包钢液面上,起到保温、防止二次氧化和吸附钢液内的非金属夹杂物的作用。FGJ-MZ镁质覆盖剂，具有保温性能强、吸附夹杂物强、铺展性好等特点。FGJ-1、FGJ-2高钙质覆盖剂是采用预熔型材料和喷雾造粒技术生产的高钙质覆盖剂,具有保温性能强、吸附夹杂物强、铺展性好等特点。

It are generally used to cover on tundish liquid steel, working to preserve heat, prevent reoxidizing and adsorb nonmetal inclusions in liquid steel. FGJ-MZ magnesium covering agent does well in heat preservation, inclusion adsorbability and spreadability. FGJ-1、FGJ-2 high-calcium covering agent are made of pre-melting material and through technique of spray granulation. It has excellent heat preservation, inclusion adsorbability and spreadability.
