Calcium-Silicon Alloys are used as deoxidizer and desulfurizer in the manufacturing of high grade steel. Indeed, Calcium and Silicon both have a strong chemical affinity for oxygen. Especially calcium, have a strong chemical affinity not only for oxygen, but also for sulphur and nitrogen. The steel industry accounts for around 90 % of global CaSi consumption.
The alloy is also used for the modification of non-metallic inclusions. Calcium Silicon is used to control the shape, size and distribution of oxide and sulfide inclusions improving fluidity, machinability, ductility, and impact properties of the steel product. The calcium liquefies the suspended solid inclusions of aluminium oxide), a principal source of fatigue failure in highly stressed alloy steels, that are always present in aluminum-killed steels (Al203 is transformed by Ca into CaO:Al2O3). Furthermore, the material properties of steel are improved: the calcium aluminates formed are largely undeformable in the solidified steel and allow high isotropy of the material properties to be maintained after working of the steel.
Calcium Silicon can be obtained in lump, crushed or powder form. The most widely used method for intergrated steel applications is in the form of cored wire. This is mainly because calcium has a low density and high reactivity in the ladle making it difficult to introduce and retain in the melt. Cored wire eliminates these variables: CaSi powder is blown deep into the steel melt through immersion of steel tubes.
Calcium silicon barium-containing alloy is an effectively new type of composite alloy, which is deoxidizer and desulfurizer in steelmaking and has the performance of dephosphorization, in addition which is also inoculant and metamorphic agent in casting.
Description:
Silicon-barium-calcium alloy is a kind of iron alloy material in the steelmaking industry. lts main components aresilicon, barium and calcium.
Function:
1. Silicon-barium-calcium alloy is a good new type of deoxidizer in steelmaking, and has good desulfurizationand phosphorus capabilities. Moreover, it plays a very important role in smelting steel types with low sulfur andphosphorus content.
2. Barium effectively reduces the vapor pressureof calcium in the steelmaking temperature range and increasesthe solubility of calcium in molten steel. Barium can effectively protect calcium and reduce calcium oxidation inmolten steel to achieve the purpose of processing molten steel calcium.
