Introduction of silicon-barium-calcium composition:
Calcium carbide 35-45%, silicon dioxide 40-45%, barium sulfate 10-30%.
Characteristics and properties of silicon-barium-calcium alloy:
Silicon-barium-calcium alloy is a new type of composite alloy in barium alloys. It is a deoxidizer and desulfurizer for steelmaking, and also has a dephosphorization effect. It is a seed and modifier in casting. One of its unique features is to increase the calcium index of steel. Satisfies the need for calcium in steel smelting.
Role of Silicon-Barium-Calcium Inoculant in Ductile Iron:
In the ductile iron casting process, in addition to using spheroidizers to improve product performance, silicon barium calcium inoculant is also a widely used additive product. Silicon-barium-calcium inoculants can promote graphitization, reduce the tendency to form white cast iron, and thus improve graphite morphology;
The role of silicon-barium-calcium inoculants in steelmaking:
Silicon-barium-calcium primers are a new type of composite alloy that combines elements of silicon, barium, and calcium. Silicon-barium-calcium primers effectively reduce the calcium vapor pressure and increase the solubility of calcium in molten steel in the temperature range of steel smelting. At the same time, silicon-barium-calcium inoculants also reduce calcium oxidation, thereby achieving the effect of calcium treatment of molten steel.
The role of silicon-barium-calcium in graphite production:
Silicon-barium-calcium inoculants can refine graphite and improve its strength. For ductile iron castings, they can make the graphite in ductile iron thin and improve the degree of spheroidization. Strong anti-crisis ability, preventing the decline accompanying spheroidization. Low sensitivity to wall thickness and uniform structure. They significantly reduce the tendency to form white iron, reduce the relative hardness and improve the cutting properties of castings.
