Product Description

Product Information
Our crushed silica chips are popular in the metallurgical industry due to the 
1. Accelerated cooling: In steel mills and alloy mills, gravel can be used to accelerate the cooling of molten metal, so that the metal can solidify quickly, thereby improving production efficiency.
2. Cooling and fire reduction: In metallurgical production, metal materials need to be treated at high temperatures, and excessive temperature will lead to deformation, cracking, and explosion, which may occur in serious cases. Crushed stone can be used to lower the temperature of the metal, prevent the metal from overheating, and reduce the burning temperature of the flame.
3. Bottom material: During the melting process, the crushed stone can be used to spread the bottom of the furnace to prevent the metal from coming into direct contact with the furnace wall and reduce the burning loss of the furnace.
4. Filter material: In the liquid metal treatment, gravel can be used as the filter material to remove impurities in the metal and improve the purity of the metal through filtration.
5. Plasma spray material: In steel mills and alloy mills, gravel can be used as plasma spray material for cleaning and rust removal, making the metal surface smoother and smoother, and improving the quality of the product.

Application Fields
Meanwhile, silica chips, also known as flint gravels, can be used in a variety of fields.
First of all, in the field of construction, silica chips can be used in the production of building materials such as concrete, cement, masonry, etc.
Secondly, in the field of metallurgy, can be used as a metallurgical raw material to remove impure substances in the process of steelmaking, ironmaking, copper smelting, etc.
In addition, can also be used as a casting raw material for the manufacture of various castings such as automobiles, machinery, and ships.
Finally, in some high-tech fields, such as electronics, optoelectronics, semiconductors, and other industries, silica chips are also an indispensable material.
