Alloys cored wire is a special form deoxidizer for the steel making industry. It is a core wire made of various specific alloying element powders or grains, physically mixed in a certain proportion, and then tightly wrapped with a thin iron sheet.
Size: φ13mm – φ15mm cored wire
Package: 1Mton or 2Mton per Roll
Alloys cored wire is beneficial to adjust and control the content of easily oxidizable elements and trace elements, reduce smelting cost, shorten smelting time, and accurately control the content of ingredients. It can purify molten steel and partially change the nature and shape of inclusions, and improve the quality and casting state of molten steel.
The use of cored wire in steel making or cast iron production can avoid bringing gas into molten steel. the alloy elements react smoothly in the molten steel, which can avoid secondary oxidation. After the reaction, the floating rate of the inclusions is fast, and the purification treatment effect is uniform.

Ferro silicon is widely used as deoxidizer and alloy additive in steel making, and also can be used as an inoculant and nodulizer for cast iron. Ferro silicon powder or atomized ferro silicon powder can be used as coating for welding rod production.
Rare earth magnesium ferro silicon alloy refers to an alloy made of ferro silicon, calcium, magnesium, rare earth, etc. through melting configuration. It is a good spheroidizing agent with strong deoxidation and desulfurization effects.
Ferro silicon barium is suitable for inoculation treatment of gray cast iron or ductile iron with strict requirements on air tightness or leakage. Ferro Silicon Barium is easier to dissolve and absorb than ordinary inoculants, and can reduce the gas content in molten iron.
