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

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.
