Silica Bricks for Glass Furnaces Introduction Silica bricks for glass furnace refers to the silicon refractory product used in the high temperature part of the masonry glass kiln (not in contact with the glass liquid).Glass kiln silica brick has high temperature and volume stability, no pollution to glass liquid, chemical corrosion resistance, small bulk density, and can reduce the weight of
Silica Bricks & Blocks. Silica Refractory Bricks have the advantages of high strength at high temperatures, residual expansion, low specific gravity, high expansion coefficient at low temperatures and low expansion coefficient at high temperatures. Silica Refractory Bricks are mainly used for; Glass tank crown; Copper refining furnace
Silica Brick for Glass Furnace Application: Silica brick for glass furnace is made of siliceous material with over 93% of silicon to build glass furnace. It has strong acid slag corrosion resistance and high loading softening temperature, and doesn ' t shrink after reheating. Specification:
The tests were conducted in a soda-lime industrial glass furnace with a oxy-firing combustion process. Silica and mullite refractory specimens were located in 3 regions of the furnace: (1) close to the burner block and installed at the back wall, (2) at the left side of the furnace throat, and (3) at the right side of the furnace throat.
Silica brick is the acid refractory,which consist mainly of tridymite, cristobalite, and a small amount of residual quartz and glass phases. The silica content is 94% or more. It has acid slag corrosion resistance and higher high temperature strength. The load softening start temperature is 1620~1670 °C.
Most furnaces use liquid fuel, gaseous fuel or electricity as energy input. Induction and arc furnaces use electricity to melt steel and cast iron. Melting furnaces for nonferrous materials use fuel oil. Oil-fired furnaces mostly use furnace oil, especially for reheating and heat treatment of materials.
Common Silica Brick. Description Adopts high quality silica and advanced technology, our silica bricks High Quality Silica Brick A brief introduction of silica brick Silica brick is a kind of acid refractory Silica Hot Repair and Mortar Directions for use of silica hot repairing mix The silica hot repairing mix i Silica Brick For Glass
Mainly used for coke oven of coking chamber and combustion chamber partition, steel open hearth of regenerative chamber and sediment chamber, soaking furnace, glass furnace, refractory silica brick materials and ceramic firing kiln and kiln of vault and other supporting parts.
Silica brick is made of quartz stone material, the content of SiO2 is above 96%,it has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C,RUL is beyond 1680°C.
SiO2 has different types of crystals in different temperatures, and the transform between the crystals will cause the change of the bulk.
2015814Silica brick is one of the most commonly used refractories. Due to its low cost, high creep resistance and low pollution to glass, it is widely used in the crown of the glass furnaces. Silica brick is a kind of basic refractory and has good corrosion resistance to acid slags.

The higher SiO2 content in silica sand, the higher temperature silica bricks resist. Silica bricks are used in the roof and superstructure of glass melting tanks as well as for hot repairs. Our silica brick advantages--Adopts high quality silica and advanced technology, our silica bricks enjoy the advantages of high purity, long service life
Refractory Selection for the Container Glass Furnace | glassonweb . Sep 15, 2015 Refractory is one of the most important factors that affect the quality of the Generally, container glass furnaces employ silica brick in the crown, due to block and sintered brick are used in the channel of the container glass.
P-D Refractories CZ a.s. is one of the biggest producers and suppliers of refractory products and raw materials. We produce and supply complete or partial linings of the thermal aggregates, especially for coke ovens, blast furnaces (including hot blast stoves), glass furnaces, electrolyzers for the primary production of alumina and others.
Glass melting furnaces, particularly of high pulling rate, are lined with various high quality refractories. Most glass manufacturers have been preferring super duty Silica Bricks for the crown because crown constructed with Super Duty Silica Bricks can be insulated, resulting in saving of 10-12% input energy.
The super-duty silica bricks for glass melting tank is characterized by high purity, less impurity, good corrosion resistance, higher bulk density, complete phase transformation, lower residual quartz, high RUL, lower thermal expansion and stable volume a
Silica mortar is mainly used for laying and repair of coke oven, hot blast stove, glass melting furnace, melting furnace and other masonry of high quality silica bricks industrial furnace. Features: 1.High adhesive strength. 2.High refractoriness. 3.Excellent refractoriness under load. 4.Good installation performance. Mixing sequence: 1.
Refractories used for glass furnace are required to withstand higher temperatures, sharper temperature changes, stronger chemical attack, and more severe stress damage. Only with a variety of high-quality refractory materials, the advantages of high efficiency, energy saving and low pollution of the new kiln technology can be realized.
