特点：

1．增加石墨形核核心，增强石墨形核能力。

2．降低铁水的过冷度、降低铸件白口倾向。

3．减少灰铸铁中的过冷石墨，促使A型石墨的生成。

4．延长炉衬使用寿命。

5．良好的脱氧效果，净化铁水。

6．在球铁生产中加入可增加石墨球数、提高球化率，使石墨球更加圆整细小，并可减少球化剂的加入量。

7．代替硅铁熔炼使用，可降低硅铁用量，减少皮下气孔。

   适用范围：铸铁、铸钢。

   粒度：1—5mm

   包装：25kg编织袋或1000kg吨装袋包装

Characteristics：    

1．Increase graphite nucleation core and enhance graphite nucleation ability．

2．Reduce the supercooled degree of molten iron and reduce the tendency of casting white mouth．

3．Reduce the supercooled graphite in gray cast iron，promote the formation of type a graphit．

4．Prolong the service life of the lining．

5．Good deoxidation effect，purifying molten iro．

6．In the production of ductile iron can increase the number of graphite balls，improve the rate of spheroidal graphite more round and small，and can reduce the amount of the addition of the ball agent．

7．Instead of Ferrosilicon smelting，it can reduce the amount of ferrosilicon and reduce the porosity of the skin.

   Scope of application：cast iron，cast steel

   particle size：1-5mm

   packing：25kg woven bag or 1000kg bagged packing．
