Metal Industries

When making raw iron, quartz granulesare used to create slag in the blast furnace process. They are also employed as a protective covering in steel gutters and during the blast furnace process.

Our Quartz (Silica) Specifications

• High SiO2 content (99.5% to 99.9%)
• Low alkali concentration; generally unavailable
• Low Fe content of 0.008% or less
• Seven Mohs hardness

Quartz specifications suitable for use in metal industries

• The requirements for using quartz granules and powder can differ from business to business, but high-purity quartz is employed in furnaces and refractory applications.
• Industrial sand is critical in the ferrous and nonferrous foundry industries. Because of silica's high fusion point (1650-1760°C) and low rate of thermal expansion, stable cores and molds are produced that are compatible with all pouring temperatures and alloy systems. Its chemical purity also aids in avoiding interactions with catalysts and increasing the curing rate of chemical binders. Following the casting process, core sand can be recycled thermally or mechanically to create new cores or molds.

Specification of Quartz powder and granules:

• Sio2 above 98%
• Fe2O3: Should be around 0.04% or below
• Other trace elements: should be below 1.0%
• No trace elements or contamination like clay, sand, etc.
