Silicon Barium Siba Factory Supply

Calcium Silicon Barium (CaSiBa) is an iron alloy material composed of calcium (Ca), silicon (Si) and barium (Ba). It is widely used in the metallurgical industry, especially in the steel smelting process, as an efficient deoxidizer, desulfurizer and inclusion modifier. ​

I. Introduction to Silicon Barium

1. Chemical composition and morphology
The main components of silicon barium alloy include:

Calcium (Ca): 10%-30%

Silicon (Si): 40%-60%

Barium (Ba): 10%-20%

In addition, it also contains trace amounts of impurities such as iron (Fe) and aluminum (Al). ​The appearance is usually grayish white or silver gray in block or granular form with a metallic luster. ​

II. Application fields

1. Metallurgical industry
Deoxidation and desulfurization agent: Calcium and barium have strong reducing properties, which can effectively remove oxygen and sulfur from molten steel and improve the purity of steel.​

Inclusion modifier: Barium can change the shape and distribution of inclusions in steel, refine grains, and improve the mechanical properties of steel. ​

Alloy additives: Used to produce special steels, such as high-strength steel, low-alloy steel, stainless steel, etc., to improve their performance. ​

2. Casting industry
Inoculant for ductile iron: Promote graphite spheroidization and improve the mechanical properties and processing properties of castings. ​

Inoculant for gray cast iron: Improve graphite morphology and improve the strength and toughness of castings. ​

III. Craftsmanship (preparation and process)

1. Raw material preparation
The main raw materials include limestone, silica, barium ore (such as barite) and reducing agent (such as coke). ​

2. Smelting process
Use submerged arc furnace or electric arc furnace for high-temperature smelting, and control the temperature above 1500°C to reduce the oxides in the raw materials to form silicon-barium alloy.​

3. Forming and processing
The smelted alloy liquid is cooled to form a block or granular product, which is then crushed, screened, and packaged according to particle size. ​

4. Key points of process control
Strictly control the purity of raw materials and reduce the impurity content. ​

Optimize the furnace temperature and the amount of reducing agent to ensure the stability of the alloy composition. ​

Adopt advanced smelting technology to improve product quality and production efficiency. ​

IV. Advantages of silicon barium

Efficient deoxidation and desulfurization: The synergistic effect of calcium and barium makes the deoxidation and desulfurization effect better. ​

Improve steel quality: refine the grains, improve the strength, toughness and fatigue resistance of steel. ​
Metal powder mesh

Improve casting quality: improve graphite morphology and reduce casting defects. ​

Reduce costs: reduce the addition of other alloying elements and reduce production costs. ​
