珍珠岩    （除渣剂、保温覆盖剂、聚渣剂）         
                                             概述：                 本产品系环保型高效聚渣、除渣、保温覆盖剂。它能有效防止熔渣粘附于浇包、炉衬及进入铸件中，减少铸件夹渣缺陷，同时对金属液起覆盖保温作用，减少氢、氧、氮对金属液的侵入。         
   产品特点：加入量少，聚渣能力强，易于结壳，去除渣为脆性，不粘包、不污染金属液、不挥发、化学结构稳定，使用时无烟尘、无气味，可保持生产现场清洁环境。

   使用说明：     1     、熔炼炉熔炼时，当金属液化清后，在金属液表面撒少量除渣剂初步去渣，然后撒一薄层覆盖在金属液表面，起保温和聚渣作用，出炉前扒渣。         
    2     、金属液出水前，可在包底部撒少许除渣剂。但建议在铸铁出水前，勿在浇包底部放除渣剂，以免影响球化孕育效果。         
    3     、浇包内铁水上表面撒少许除渣剂，扒渣后，在撒少许覆盖可浇注。         
    4     、加入量约为金属液重量的     0.3％-0.5％     。
