New type silicon calcium 

the calcium silicon alloy is made up of elements silicon, calcium, and iron compound alloys, is an ideal compound deoxidizer, desulfurization agent.

Starting around 1907, the calcium silicon alloy was produced by silicon thermal method. At present calcium alloy can be used instead of aluminum for final deoxidation, is applied to high-quality steel, special steel and special alloys production., Such as rail and low carbon steel, stainless steel, steel and nickel base alloy, titanium alloy and other special alloy, are available the calcium silicon alloy as deoxidizer.

The calcium silicon alloy by calcium, silicon and impurity content is different, divided into five grades, its chemical composition in accordance with the provisions of the table below.

Physical state:

The calcium silicon alloy should be a massive supply, the large weight must not exceed 10 kg, less than 15 mm * 15 mm of fragments, the amount shall not exceed the number of 10% of the total.
