Characteristics of silicon calcium cored wire
As a kind of alloy cored wire, the raw materials of silicon calcium cored wire include silicon calcium alloy, and the functions of silicon calcium cored wire and silicon calcium alloy are similar. In order to let everyone understand the silicon calcium alloy, it will be introduced briefly.
Silicon calcium alloy is a composite alloy composed of silicon, calcium and iron, which is an ideal Compound Deoxidizer and desulfurizer. It is widely used in the production of steel, low carbon steel, stainless steel and other special alloys such as nickel base alloy and titanium base alloy. It is also suitable to be used as a temperature increasing agent in converter steelmaking workshop, as a inoculant of cast iron and an additive in the production of nodular cast iron.
Calcium and silicon have strong affinity to oxygen. In particular, calcium has a strong affinity with oxygen, and has a strong affinity with sulfur and nitrogen. Therefore, silicon calcium alloy is a kind of ideal compound oxygen and desulfurizer. Silicon alloy not only has strong deoxidation ability, but also can improve the properties of steel, improve the plasticity, impact toughness and fluidity of steel. At present, silicon calcium alloy can replace aluminum for final deoxidation. It is used in the production of steel, special steel and special alloy. For example, silicon calcium alloy can be used as deoxidizer for rail steel, low carbon steel, stainless steel and special alloys such as nickel base alloy and titanium base alloy. It can also be used as inoculant of cast iron and additive in nodular cast iron production.
