Product Introduction
Si-Ca alloy is a silicon-calcium alloy material that is suitable for improving metal purity and performance during steel smelting, alloy deoxidation and casting processes.
Product Usage
High-Temperature Oxidation-Resistant Applications
This alloy forms a stable oxide film in high-temperature environments, protecting the metal substrate from corrosion.
Metallurgical Deoxidation and Desulfurization
Its chemical composition enables efficient oxygen and sulfur removal in steel and non-ferrous metal smelting, improving metal purity and mechanical properties.
Raw Materials for Specialty Alloy Manufacturing
Si-Ca alloys can be used as base materials for the production of alloy steels and casting alloys, with controlled silicon and calcium content.

FAQs
Q: Which steel grades are suitable for Si-Ca alloy?
A: Si-Ca alloy is suitable for carbon steel, stainless steel, and alloy steel, especially for controlling inclusion morphology.
Q: How should the alloy be stored?
A: Si-Ca alloy should be stored in a dry, well-ventilated environment to avoid moisture and oxidation.
Q: How should the alloy be added to molten steel?
A: The alloy should be sprinkled evenly onto the surface of the molten steel to avoid excessive addition at once, which could cause a rapid reaction.
Q: Can Si-Ca alloy be mixed with other deoxidizers?
A: The alloy can work synergistically with aluminum or silicon deoxidizers, but the order and amount of addition must be controlled.
Q: What are the packaging requirements for the alloy?
A: The alloy should be packaged in moisture-proof, sealed packaging to ensure it is protected from moisture during transportation and storage.
