Silicon-barium inoculant is an important casting material. Its particle size is different and the corresponding application scenarios will also be different.
(1) 0-0.2mm
Application scenario: In-mold inoculation
Features: Accurate inoculation and higher efficiency.
(2) 0.2-0.8mm
Application scenario: Stream inoculation
Features: The control of inoculation amount is relatively accurate.
(3) 1-3mm
Application scenario: In-ladle inoculation
Features: The inoculation time needs to be controlled at more than 70% of the iron-out time.
(4) 3-8mm
Application scenario: In-ladle inoculation or in-furnace inoculation
Features: Suitable for different casting process requirements.
Silicon-barium inoculant plays a significant role in the casting field, especially in the production of gray cast iron and ductile iron. It can increase the number of graphite nodules (in ductile iron), reduce the tendency of white cast iron, refine grains, promote graphitization, improve graphite morphology and distribution, increase the number of eutectic clusters, and refine matrix structure.
Silicon-barium inoculant can also improve the mechanical properties of castings, such as strength, hardness and toughness. At the same time, it also has strong anti-degradation ability, which can ensure the performance stability of castings during long-term use.
Silicon-barium inoculant, as a vulcanization accelerator, can greatly increase the vulcanization speed of rubber, shorten the vulcanization time, enhance the stability and strength of sulfide, thereby improving the quality and service life of rubber products.
In the ceramic industry, silicon-barium inoculant can be used as a retarder to control the heating and flow rate of ceramics and ensure the quality and stability of ceramic products.
Particle size selection: When selecting silicon-barium inoculant, the appropriate particle size should be determined according to the specific casting process and casting quality requirements. Too large or too small particles may affect the inoculation effect.
Quality control: High-quality silicon-barium inoculants should have uniform particle size distribution, consistent color and gloss, and regular shape and structure. When purchasing, suppliers with relevant production qualifications and experience should be selected, and attention should be paid to their product quality and production management level.
Use and storage: The amount of silicon-barium inoculants added should be strictly controlled during use to avoid problems such as excessive inoculant amount leading to molten iron viscosity and slag inclusion. At the same time, dry, ventilated, and light-proof conditions should be maintained during storage and transportation to prevent moisture, deterioration, or other contamination.
