Quartz sand have unique physical and chemical properties, make its in aviation, aerospace, electronics, machinery, and today a significant role in the rapid development of IT industry, especially its internal molecular chain structure, the change law of crystal shape and crystal lattice, make its have the high temperature resistant, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect, and its unique optical properties.
Refractory is quartz sand as the main component, with a compact structure, coagulation reaction effect is obvious, continuous self-cleaning filtration, reducing the raw water suspended matter (SS) content, long service life characteristics.According to various needs to add different additives from the scientific ratio.Advantages of low price, good acid resistance, non - stick slag.Refractory quartz sand is a necessary material for lining of induction furnace used in metal smelting.
The main technical indexes of quartz sand as refractory are as follows:
SiO2 97.5% or higher
Al2O3:0.7-0.3%
Fe2O3:0.4-0.1%
H2O 0.5% or less.
Bulk density: 1.9-- 2.1g/cm.
Liner volume density: 1.75-- --1.8g/cm.
Fire resistance: A[1500---1700].
Fire resistance: H, C[1300---1450]
Particle size: 5.1---- ---0.021mm.
Refractory quartz sand is widely used in smelting black and non-ferrous metals of power frequency, medium frequency, frequency conversion, cored induction furnace lining.Quartz sand can be used as refractories, because quartz sand in 1750 degrees Celsius below the physical and chemical indicators are very stable, quartz sand filter material is white and is a kind of crystal, in normal conditions is a kind of white spherical crystal.High purity quartz sand is mainly used for porcelain blank and glaze in refractory materials, high silica brick for kiln, common silica brick and silicon carbide, etc.
Refractory widely used, quartz sand market prospects are very broad, so have a quartz sand production line is your best choice.Weifang guote mining equipment co., LTD specializes in customized quartz sand production line, plate sand production line, quartz powder production line.
