Reasonable Calcium Silicon Lump For Steelmaking Additive Chemical Composition Ca Si P S C Al
Sales Calcium Silicon Lump Calcium with Reasonable Price
Silicon calcium (Si-Ca) is an alloy composed primarily of silicon (Si) and calcium (Ca), often used in metallurgical processes, particularly in the steelmaking and cast iron industries. It serves as a deoxidizer, desulfurizer, and inoculant to improve the quality and properties of metals.
Function
silicon calcium is a versatile and essential alloy in metallurgy, playing a critical role in improving the quality and performance of steel, cast iron, and other metals. Its ability to deoxidize, desulfurize, and modify inclusions makes it a valuable material in modern industrial processes..
Specification
| Grade | Ca(≥) | Si | Al(≤) | C(≤) | S(≤) | P(≤) |
| Ca31Si60 | 31 | 55-65 | 2.4 | 1.0 | 0.05 | 0.04 |
| Ca28Si60 | 28 | 55-65 | 2.4 | 1.0 | 0.05 | 0.04 |
Particle size: 10-100mm,10- 50mm, 0-3mm, 2- 6mm and different granularities according to your needs.
Applications
Steelmaking:
Deoxidizer: Silicon calcium is added to molten steel to remove dissolved oxygen, preventing the formation of oxides that can weaken the steel.
Desulfurizer: It helps remove sulfur from steel, improving its mechanical properties and reducing brittleness.
Inclusion Modification: It modifies the shape and distribution of non-metallic inclusions, enhancing the steel's toughness and ductility.
Cast Iron Production:
Inoculant: Silicon calcium is used to improve the microstructure of cast iron, promoting the formation of graphite and enhancing strength and machinability.
Non-Ferrous Metallurgy:
It is also used in the production of certain non-ferrous alloys, such as aluminum and magnesium alloys, to refine their structure and improve properties.
Welding Electrodes:
Silicon calcium is sometimes added to welding electrode coatings to improve weld quality and reduce impurities.
Packaging:Dark gray luster, 10-100mm granularity, polyethylene plastic bags, net weight of 1000KG per bag, gross weight of 1003KG per bag.
