Foundry Silica Particles

Description

The Foundry Silica Particles is an inoculant for ferrous and non-ferrous metals in the foundry industry, such as steelmaking and ironmaking. It consists mainly of silica sand with a thin film of burnt carbon on the surface, as well as a small amount of adhesive and dust. The material has a high melting point and thermal stability, and can withstand melting to any particle size you want, reducing the hardness of the metal when smelting and improving its processing properties. It can also increase the tensile strength of various metals by increasing the pearlite content, making it less prone to thermal embrittlement at high temperatures, so it is beneficial to the processing of cast iron and special steel.

Features

1. Various sizes: The standard particle size of Foundry Silica Particles is 0-3 mm and 0-5 mm, and various grades and sizes are also available for customization. This allows it to meet specific casting application requirements such as sand casting, investment casting and metal mold casting.

2. High efficiency: its particle size is uniform and does not contain excessive impurities and dust, ensuring full contact with metal materials during smelting. Therefore, it can effectively increase the fluidity of molten iron, improve the toughness and deoxidation speed of pig iron and castings.

3. Wide use: In addition to helping to improve the efficiency of steel casting, it can also be used as an alloying element additive and added to the production process of spring steel, heat-resistant steel and other materials to improve their hardness and yield strength.

Its chemical composition includes

70% - 73% Si

1.5% - 3% Al

1% - 2% Ca and residual fe

Particle size: 0-3mm, 0-5mm

Silicon content: 55
