产品特点

  1．本产品适用于铸钢、铸铁件砂型普通用明冒口，仅用覆盖剂不用保温冒口即可使冒口孔形状呈“U“形、平底、无二次缩孔，补缩效率达30％。

  2．冒口重量减少50％一75％。

适用范围

  1．等钢水上升到冒口高度的2／3时投入为佳，也可以在浇注停止立即投放。若待钢水表面结膜后再投放效果将明显减弱。

  2．控制浇注高度不能与砂箱相平，应留20一一40mm高度以备堆放覆盖剂。浇注控制原则：宁低勿高。

Cha racteristics：  

  1．This product is applicable to cast steel，cast iron sand—type common use of the mouth，only with covering agent without insulation riser can make the riser hole shape is“U”shape，flat bottom，no

    secondary shrinkage，the shrinkage efficiency of up to 30％．

  2．The riser weight is reduced by 50％一75％．

Scope of application：

  1．When the molten steel rises to the riser height of 2／3，the investment is better，can also stop immediately in pouring．If the surface of the molten steel after the conjunctival drop effect significantly weakened．

  2．The control pouring height cannot with the sand box phase level，should leave the 20一一40mm height to prepare for the stacking covering agent．Pouring control principle：ning low not high

  package：25kg woven bag or 1 000kg bagged packing．
