How does a silicon calcium alloy work as a deoxidizer?
In steel smelting will use a variety of deoxidizer, and different deoxidizer deoxidizer effect is different, the common deoxidizer has ferric silicon, silicon barium calcium, silicon aluminum barium calcium, etc., silicon barium calcium as a plurality of deoxidizer, with its good deoxidizer effect, more popular with manufacturers. Next, let's take a look at the introduction of silicon calcium manufacturers:
Silica-calcium alloy is a composite alloy composed of element silicon, calcium and iron, which is an ideal compound deoxidizer and desulfurizer. It is widely used in the production of low carbon steel, stainless steel and special alloys such as nickel base alloy and titanium base alloy. It is also suitable for the heating agent used in the converter steel mill. It can also be used as inoculant of cast iron and additive in ductile iron production.
Both calcium and silicon have a strong affinity for oxygen. Calcium, in particular, has a strong affinity not only for oxygen, but also for sulfur and nitrogen. So the silicon calcium alloy is a kind of ideal compound oxycolic agent, desulfurizer. Silicon alloy not only has strong deoxidization ability, deoxidization product is easy to float up, easy to discharge, but also can improve the performance of steel, improve the plasticity, impact toughness and fluidity of steel. At present, silicon - calcium alloy can replace aluminum for final deoxidization. Used in steel and alloy production. For example, rail steel, low carbon steel, stainless steel and nickel-based alloy, titanium based alloy and other special alloys, can be used as deoxidizer silicon calcium alloy. Silica-calcium alloy is also suitable for heating agent used in converter mill, inoculant in cast iron and additive in ductile cast iron production.
