calcium silicon uses
The ferro alloy material is essential factor in industrial steel making. Anyang Huatuo Metallurgy is calcium silicon manufacturer and also provide other many different types of ferro alloy materials. The calcium silicon alloy is hot sale product in our factory. It is mainly made of silica, lime and coke. So. the calcium silicon uses include deoxidizer and desulfurizer in industrial steel making and casting.
Calcium silicon alloy is an ideal deoxidizer and desulfurizer for smelting high quality steel. Because calcium and silicon have a strong affinity with oxygen. In particular, calcium has not only a strong affinity with oxygen, but also a strong affinity with sulfur and nitrogen. For example, for continuous casting steel, especially aluminum containing, calcium-treated alloy must be used to prevent nozzle nodulation. Moreover, the silicon alloy can make the deoxidation product easy to float and discharge and improve the performance of the steel and the plasticity, impact toughness and fluidity of the steel. At present, silicon calcium alloy can replace aluminum for final deoxidation.
In the steel making process, silicon calcium alloy can change the behavior of residual inclusions in the steel, reduce the content of inclusions and improve the mechanical properties of the steel. Therefore, it is a purifying agent for the production of high-purity steel. The calcium silicon is applied in high quality steel, special steel and special alloy production like rail steel, low carbon steel, stainless steel and nickel based alloys and titanium-based alloy.
Calcium silicon alloy is also suitable as a warming agent for converter steel workshops. Silicon calcium alloy can also be used as an inoculant for cast iron and an additive in the production of ductile iron. In recent years, the method and process have been greatly improved for adding silicon calcium alloy to molten steel. For instance, the silicon calcium powder is wrapped in a core wire form by a wire feeder or a LF refining furnace. The use of feeding process greatly improves the utilization of calcium in the molten steel and quality. So Anyang Huatuo Metallurgy introduce knowledge about calcium silicon uses to help and teach customer how to distinguish the quality and purchase in the future.
