ferro calcium cored wire

Ferro calcium cored wire is generally used for calcium treatment. It is an efficient and ultimate refining technology for the steel making and casting, it can be used to deoxidation, desulfurization, change the shape of inclusions, promote the floating of inclusions, purify molten steel and improve the pouring of molten steel etc, can also increase the content of silicon to molten steel, at the same time, appears outstanding advantages such as reduce the production cost, improve economic benefits and environment protection.

The main materials of ferro calcium cored wire is as followings:

1.Calcium metal granules, always adopt the electrolytic calcium (the calcium comes from CaCl2 electrolysis is called the electrolytic calcium), it is in the shape of granule, packaging in the iron drum lined with sealed argon-filled plastic bag.

2.Ferro powder, always adopt the second refined reduced iron powder, it requires the content of ferro more than 98%, the content of sulfur and phosphorus less than 0.03%, the content of silicon less than 0..25%, and the content of moisture less than 0.5%.

3.Covering steel strip, always adopt cold rolled plate in flat, the thickness is 0.4~0.43mm, the width is 54~56mm.

The high quality of ferro calcium cored wire need it to be no powder leaks, no slits, no fold likes, no virtual packages, no empty packages, the wrapped powder has a uniform density and the surface is smooth and free of oil, it is generally in the diameter of 13mm, and the package of the cored wire generally adopt steel belt plus the waterproof plastic film and iron cage.

Anyang Huatuo Metallurgy Co.,Ltd now owned five cored wire production lines, they ever meet the problems of powder leakage line,uneven feeding,problem of butt of steel strip and irregular wiring etc, but after continuous improvement of technology, they overcome all problems, now has become a professional manufacturer and exporter of the cored wire with more than 20 years experience, welcome for your consult.
