SiCa16

Since calcium has a strong affinity with oxygen, sulfur, hydrogen, nitrogen and carbon in steel fluid, silicon calcium16 is mainly used for deoxidization, degassing and fixation of sulfur in steel fluid.The addition of calcium silicon into the molten steel produces a strong exothermic effect.Calcium turns into calcium vapor in steel liquid, which has a stirring effect on the liquid steel, and is favorable for non-metallic inclusions to rise.After deoxidization, the silicon calcium alloy produces non-metallic inclusions with large particles and easy to float, and changes the shape and properties of non-metallic inclusions at the same time.Therefore, silicon calcium alloy is used to produce clean steel, high quality steel with low oxygen and sulfur content, and special performance steel with extremely low oxygen and sulfur content.The addition of silicon-calcium alloy can eliminate the swelling of aluminum final deoxidizer steel at ladle mouth and the blockage of continuous cast steel | ironmaking tundish mouth.In the outside refining technology of steel, the content of oxygen and sulfur in steel is reduced to very low by desulphurization and desulphurization with silicon-calcium powder or core wire.It can also control the sulfide form in steel and improve the utilization rate of calcium.In the production of cast iron, silicon calcium alloy not only deoxidizes and purifies, but also plays an inoculating role, which is helpful to form fine or globular graphite.The graphite distribution in gray cast iron is uniform and the white tendency is reduced.And can increase silicon, desulfurization, improve the quality of cast iron.
