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: How can the silica in zircon sand be removed during the smelting of zirconium corundum?: Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.

Q: What are the forming methods of refractory materials?: Casting molding is suitable for casting brick, electric melting brick and so on. And the machine press forming is the most widely used. The common refractory brick, clay brick and other sintered brick are adopted this method.

Q: What are the categories of bricks?: Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.

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?: It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..

Q: What are ordinary bricks, refractory bricks, hollow bricks?: According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..

Q: What are kiln bricks?: Furnace (kiln; furnace; oven) is made of refractory material used for firing products; it is a necessary facility in the formation of ceramic art. Millions of years of human porcelain history, has accumulated rich experience and made kiln style. From the primitive society to open pile burn, burn up like digging to build Steamed Buns flame round kiln, half pour flame kiln, kiln, Banpo horseshoe shaped kiln to duck's egg, indoor gas kiln, kiln kiln electric current, in the continuous improvement in the development of science and technology.

Q: What are the specifications for bricks?: Thecompressive node as a new type of 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, improve 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, it 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's the use of refractory bricks?: Refractory material of a certain shape and size.According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, ordinary brick, specific rotation. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature.For example, refractory clay brick, high alumina brick, brick, brick etc..

Q: What's the weight of the refractory bricks?: Light weight brick 1 to 1.7 kilograms; heavy clay superscript brick weighs 3.75 kilograms; light 30 plates 0.79 kilograms; light 40 plates, 1.05 kilograms
