高质量的nodulizer

Properties Appearance: silver gray section, block, not powder. Melting point :980 - 1180°C. specific gravity :4.0 - 4 .1 granularity:5 - 30mm, smaller than 5mm and larger than 30mm of it does not surpass 5% Of the total weight. Features Thenodulizer has many features,such as strong nodularization , stable composition, smooth reaction, no recession worries. Applications 1 We produce all kinds of ductile cast iron for the various plate of RE-Si-Mg alloy nodulizer.After added to the molten iron, it can play the role of nodularization, desulphurization, degas, etc. 2 It can increases the purity of the cast water , and with arsenic, zinc( low melting point impurities), it can generates compounds,which are insoluble in iron and low melting point . Remove these impurities can prevent the interference of nodularization damage. 3 For the mechanical manufacturing,it is the good nodulizer of produing ductile cast iron, also can be vermiculizer. Introduction The product can be used as nodulizer, inoculant, in line with national standards (GB/T4138-930).
