產(chǎn)品特點

  1．本產(chǎn)品適用于鑄鋼、鑄鐵件砂型普通用明冒口，僅用覆蓋劑不用保溫冒口即可使冒口孔形狀呈“U“形、平底、無二次縮孔，補縮效率達30％。

  2．冒口重量減少50％一75％。

適用范圍

  1．等鋼水上升到冒口高度的2／3時投入為佳，也可以在澆注停止立即投放。若待鋼水表面結(jié)膜后再投放效果將明顯減弱。

  2．控制澆注高度不能與砂箱相平，應(yīng)留20一一40mm高度以備堆放覆蓋劑。澆注控制原則：寧低勿高。

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．
