Silicon calcium alloy, also known as silicon-calcium composite deoxidizer, is an important inoculant and refining agent for steelmaking. It is mainly composed of silicon, calcium, and iron, and is produced through a smelting process. The primary function of silicon calcium alloy is to improve the quality of steel by removing impurities and adding desirable elements. It is widely used in the production of low-alloy structural steels, pipelines, shipbuilding, and other industries.

China is the world’s largest producer and consumer of silicon calcium alloy. With its abundant raw materials and mature production technology, China produces high-quality silicon calcium alloy at a large scale. The country’s annual production of silicon calcium alloy is around 2 million tons, accounting for more than 60% of the global output. Chinese manufacturers also have a competitive advantage in terms of price and quality, making their products popular in both domestic and international markets.
