Silicon Calcium Alloy
Particle Size (Common): 0–10 mm / 10–50 mm / 10–100 mm (can be screened)
Packaging: 25 kg bags / 50 kg woven bags / 1 ton bulk bags (customizable liners available)
Storage: Store in a cool, dry place. Avoid moisture and oxidation.
Products Description
Silicon calcium alloy is primarily used in molten steel treatment for deoxidation, desulfurization, and improving inclusion morphology. It effectively enhances molten steel purity and is therefore widely applied in the steel smelting and casting industries.
With its rapid reaction speed and stable performance, silicon calcium alloy facilitates the flotation and removal of impurities from molten steel, thereby improving the quality of the final steel product.
Core Advantages
High Deoxidation and Desulfurization Efficiency
Synergistic action of silicon and calcium enables rapid reaction and significant treatment effects.
01
Improved Inclusion Morphology
Transforms inclusions into forms that float or are captured more readily, facilitating slag removal.
02
Stable Composition and Convenient Dosage
Controlled production ratios and diverse forms (lumps, granules, powder) facilitate application across different processes.
03
Broad Applicability
Suitable for steel smelting, continuous casting, foundry operations, and specific non-ferrous metal processes (requires trial verification).
04
Flexible Packaging & Supply
Supports small-scale trials and bulk contract supply; packaging customizable to requirements (ton bags/small bags, etc.).
05
Product Applications
- Steel Refining Stage: Added during ladle treatment or ladle processing to aid in oxygen and sulfur removal while improving inclusion morphology.
- Continuous Casting Process: Used for melt pool treatment to reduce the impact of inclusions on the surface and internal quality of cast billets.
- Casting and Alloy Manufacturing: Employed as an additive in specific alloy or casting production to enhance metal microstructure.
- Troubleshooting and Process Optimization Testing: Conduct small-scale trials for rapid diagnosis and improvement when encountering inclusions, defects, or surface quality issues.
(Note: Different steel grades and process parameters may affect performance. It is recommended to conduct small-batch trials and adjust dosage and timing in consultation with process engineers.)
FAQ
Q: Does silicon-calcium alloy alter the chemical composition of steel?
A: It is possible, especially since the addition of Ca and Si can influence the chemical composition of steel. Typically, under controlled dosage conditions, the purpose is to modify inclusions and achieve deoxidation and desulfurization. However, specific compositional changes must be monitored through chemical analysis and confirmed during the trial phase.
Q: What is the recommended dosage?
A: Dosage varies significantly based on steel grade, furnace conditions, and desired effects, making a universal recommendation impractical. We advise conducting small-scale trials and consulting technical personnel for dosage recommendations based on trial results.
Q: What particle sizes or forms are available?
A: We offer various forms including lumps, granules, or powders, and can provide screening or customized packaging according to customer requirements.
Q: What is the shelf life and storage conditions?
A: Store in a dry, well-ventilated warehouse to prevent moisture absorption and prolonged exposure to air oxidation. Shelf life is generally good when packaging remains intact. Use promptly after opening.
