The new silicon calcium aluminum is a new composite sub-alloy, which is an ideal composite deoxidizer and desulfurizer. It is used in high-quality steel, low-carbon steel, stainless steel, It is suitable for the production of stainless steel and other steels, nickel-based alloys, titanium-based alloys and other special alloys. It is also suitable for use as a temperature increase meter for converter steelmaking and can also be used for cast iron Inoculant and additive for ductile iron.
. use
Silicon, calcium and aluminum all have strong affinity with oxygen, especially aluminum and calcium, which not only have strong affinity with oxygen, but also have strong affinity with sulfur and nitrogen. Therefore, silicon calcium aluminum is an ideal composite deoxidizer. Silicon calcium aluminum not only has strong deoxidation ability, but also the deoxidized products are easy to float and discharge. It can also improve the performance of steel and enhance its plasticity and toughness. At present, silicon-calcium-aluminum can replace silicon-aluminum-iron and silicon-aluminum-barium-calcium alloys for final deoxidation.
