2. Related introduction

The silicon barium inoculant is a massive metallurgical material made by mixing silicon powder and barium powder according to the required ratio and steelmaking in a high-temperature furnace. It is an additive in the casting process of a foundry, which can promote graphitization and reduce the tendency of white mouth, Improve the shape and distribution of graphite, increase the number of eutectic clusters, and refine the characteristics of the matrix structure. It has a good effect in a short time (about 5-8 minutes) after the incubation treatment.

Silicon Barium inoculant use: used for ductile iron and gray cast iron

The block size of the silicon barium inoculant should be uniform and moderate in size, so as not to affect the inoculation effect, and the molten iron after incubation should be fully stirred before slagging treatment.

The amount of silicon-barium inoculant added is generally controlled at 0.3%-0.6%. Do not blindly increase the inoculation amount. Excessive inoculation amount will increase the viscosity of molten iron and the tendency of slag inclusion, keyhole, and shrinkage.

The silicon barium inoculant is a kind of inoculant that can promote graphitization, reduce the tendency of white mouth, improve the shape and distribution of graphite, increase the number of eutectic clusters, and refine the matrix structure. It can be used in a short period (about 5-8 minutes after inoculation ) Has a good effect. It is mainly suitable for general conditions in various situations or instant incubation in later stages.

Silicon-barium inoculant is mainly used in the inoculation of ductile iron and gray cast iron. The silicon barium inoculant strongly increases the graphitization core, refines the graphite, promotes the A-type graphite in the gray iron castings, and improves the strength. For the ductile iron castings, it can make the graphite in the ductile iron fine, round and improve the spheroidization grade. Strong resistance to decline while preventing the associated spheroidization decline. The wall thickness is less sensitive and the organization is uniform. Significantly reduce the tendency of white mouth, reduce the relative hardness, and improve the cutting performance of castings. Used as inoculant and spheroidizing agent in the cast iron industry.
