Silicon Barium Alloy

I. Steelmaking

Deoxidation

Silicon barium has strong deoxidation capabilities. In terms of pure deoxidation effects, one ton of silicon barium alloy can replace a certain amount of other deoxidizing materials. Adding silicon barium to steelmaking can reduce smoke and flames, lower oxygen content in steel, improve the recovery rate of elements such as silicon and manganese, reduce the addition of carbon powder, and significantly increase the yield of aluminum, thereby reducing costs.

Silicon Calcium Barium Aluminum, an alloy containing silicon and barium, is a superior deoxidizer and desulfurizer among barium-based alloys. It can minimize oxygen content in steel while facilitating the formation of complex oxides containing calcium, barium, silicon, and aluminum that readily rise to the surface of the molten steel, purifying the liquid steel and enhancing its impact toughness and machinability.

Change the nature and distribution of inclusions

Can change the nature and distribution of non-metallic inclusions in steel, improve the machining performance of steel products, thoroughly solve the problem of slag formation in continuous casting water outlets, shorten the steelmaking cycle, and has a wide range of applications, which can be fully used in the steelmaking process. At the same time, it can improve the machining performance of metals, making the molten steel flow well.

Desulfurization Function

It has a significant desulfurization effect.

II. Casting Aspects

As a Fertilizer (for Spheroidal Graphite Iron and Grey Cast Iron)

Promote graphitization related

Can promote graphitization, reduce white iron tendency, improve graphite morphology and distribution, increase the number of eutectic clusters, and refine the matrix structure. It can strongly increase the number of graphitization cores, refine the graphite, promote the formation of A-type graphite in gray cast iron parts to improve strength; for ductile iron parts, it can make the graphite in ductile iron fine and round, and improve the spheroidizing grade.

Anti-recession ability

Strong resistance to recession, with a recession resistance time twice that of 75 silicon, and the addition of barium silicon inoculant agent is less than half of that of 75 silicon iron inoculant, while preventing associated spheroidal recession. It has good effects in a short time after inoculation treatment (about 5 - 8 minutes).

Effectively reduces the supercooling of molten iron, promotes the precipitation of graphite, significantly reduces the tendency to form white iron, lowers relative hardness, and improves the machinability of castings; exhibits low sensitivity to wall thickness, enhancing sectional uniformity and reducing shrinkage porosity; features stable chemical composition, uniform particle size after processing, minimal component and quality deviations; has a low melting point (below 1300°), facilitating easy absorption during inoculation treatment, with minimal slag floating.
