Other than COB, silica bricks are used mainly in glass melting furnaces, hot blast stoves, and electric arc furnace roofs. Silica mortar In general, there are two types of mortar used, an air setting, which contains a small amount of sodium silicate, and a heat setting, which is basically the same mortar, but without the sodium silicate.
Furnace & Forehearth Refractory Fused Silica & Hot Repair Refractory SCL refractories are well accepted by various segments of the glass industry which include Container Glass, Tableware Glass, Lighting Glass, Television Glass, Lead Glass and other specialty Glasses including sodium-silicate and potassium-silicate industry.
In corner area fused cast AZS with Void Free Casting is used exclusively. Fused cast AZS is so far the primary refractory brick for glass furnace. In tin bath, alumina forming brick such as sillimanite and bottom block are used typically. Silica brick is used also quite frequently in glass furnace.
Silica fire brick are mainly used as refractory materials for protective wall of coking chamber and combustor in coke oven, regenerative chamber and slag pocket in steelmaking open-hearth furnace, soaking pit furnace and glass melting furnace, and other weight bearing area and top in ceramic firing kiln.
35 Years in Glass Industry. Inspiring People. Building Trust.. According to customer project & needs, with given drawings or descriptions, we are cutting, drilling, opening channel, shaping refractory bricks and blocks, and supplying pre-cast refractories for glass furnace forehearth, melting pool, regeneration & recuperative sections.
Silica bricks for glass melting furnaces is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase. The raw refractory material is natural silica sand whose SiO2 content should be more than 96%.
We also manufacture brulor and back refractories for unique orders (special production by drawing) are available for our customers at our factory. We always keep stock of AZS ZAC, Mullite, Zircon, Zircon Mullite, Andolusite, Silimanite, Cordierite Batts, Jargal, high and low Alumina Bricks & Blocks, Silica Bricks and Mortars.
It is a group of high-purity oxides with high melting point above 1800 ℃, non-oxide and carbon Or a variety of composite materials, based on the use of traditional production processes or special production process, and its products with special features and special use of new refractory materials, also known as special refractory materials.
High Alumina Bricks are widely used in industries of the blast furnace, hot blast stove, electric furnace, refining furnace, and glass furnace and so on. High Alumina Bricks are neutral refractory that can be divided into 4 grades: Grade I means that including 75% contents of Al2O3, Grade II means that including 60~75% contents of Al2O3, Grade
Kiln building refractory fire bricks, blocks, and tiles are stacked to form insulating furnaces, boilers or other thermal process vessel walls. The refractory fire bricks are usually cemented together with refractory mortar. P lease note: BRICKS SHIPPED UPS GROUND CARRY A $0.75 /BRICK PACKING FEE AND A $5.00 MINIMUM PACKING FEE.
Generally, container glass furnaces employ silica brick in the crown, due to its good mechanical properties at high temperature and good creep resistance. Sometimes, fused cast AZS 33# is also used in the superstructure. The drawback is the exudation of the glass phase, which will cause glass defects such as stones and stripes.
We supply Fused Cast AZS, Fused Cast a-b Alumina Jargal, Fused Cast b Alumina Jargal, Zirconia, Zirconia-Mullite, Silica, Magnesia, Sillimanite, Chamotte Refractory Bricks, Refractory Mortar for Glass Furnaces, AZS Ramming Refractory Mixes and many other refractory products that are used for glass furnaces.
200561They analyzed post-campaign AZS refractory blocks from three types of glass melting furnaces: a soda-lime container furnace, a soda-lime tubing furnace and a lead silicate TV funnel furnace. The results of this study are providing a better understanding of the link between AZS refractory corrosion and glass defects.
Special quality High Alumina bricks for Submerged Arc Furnace and CFBC Boilers. Basic Bricks : Magnesia, Mag-Chrome and Chrome-Mag for general usages, Low iron, low porosity and spall-resistant Magnesia bricks for glass industry and other special applications in Steel industry.
Coke oven should use the silica brick with small true density. And the phosphorus quartz is better than others. Process of Special Shape Refractory Brick. Generally, Special shape refractory brick was molded by dry pressing,By means of mixing the material uniformity in proportion and ageing mixture some time.
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.
Silica mullite brick materials in the iron and steel, nonferrous metals, petrochemical, machinery, electricity, light industry and other basic industries have a wide range of applications. The main application areas of refractory materials and their respective proportions in the steel industry accounted for the largest proportion.
