Fused cast AZS (alumina, zirconia and silica) firebricks are mainly categorized into 33#, 36# and 41# according to different zirconia's contents from 33% to 41%. Fused cast alumina (α-β Al2O3 and β Al2O3) firebricks are composed of alpha alumina, beta alumina and small amount of glass phase.

Both AZS and alumina firebricks have shown excellent performance in glass furnace construction.

Q: What is brick power, half brick power and full brick power difference?: Power module. Small size, high power. General use should order additional storage energy, heat dissipation, etc.. Dimensions such as brick, so called brick power supply. Half brick power supply is half the size of all brick power supply.

Q: What are the forming methods of refractory materials?: Basically there are three kinds: grouting molding, casting molding, machine forming, the three methods are applicable to different types of refractory materials, grouting molding for unshaped refractory

Q: Zirconium corundum 25 content and 40 content, how to distinguish in appearance?: It is in the production process, zirconium corundum bricks are likely to cause pollution.

Q: What are the categories of bricks?: Fired shale brick as a new building energy-saving wall materials, which can be used for masonry walls, but also has good thermal properties, in line with the construction of the building module, reduce the loss in the process of construction, loss and high work efficiency; the hole rate reached more than 35%, can reduce the weight of the wall, save the foundation engineering cost. Compared with common sintered porous brick, the Jian Ling brick has the characteristics of heat preservation, heat insulation, light weight, high strength and high construction efficiency. The product is made of shale as raw material. It is produced by high vacuum extrusion molding machine and one yard firing process

Q: What is the face brick: According to the shape and size can be divided into ordinary brick, standard brick, etc. can be used as a specific type of building furnace and various thermal equipment of high temperature building materials and structural materials, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action.

Q: Just what is in the furnace material?: Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C.

Q: What are ordinary bricks, refractory bricks, hollow bricks?: Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material

Q: What are the main constituents of refractory bricks?: Refractory brick composition is mainly composed of a variety of aggregate or aggregate and one or more kinds of sticky agent composed of mixed powder particles, when used, must be mixed with one or more liquids, mixing evenly, with strong liquidity. Different refractory bricks are different, such as silicon aluminum

Q: Outside wall tile (whole body smooth surface has small hole split brick) has cement pollution, with what product cleaning (cement, mortar, cleaning agent)?: The temporary pollution in the process of tiling should be cleaned in a timely manner with a damp cloth.

Q: Can the fire clay be reused?: Refractory soil cannot be reused.Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
