Q:With what three clay brick clay brick with six holes under what circumstances?: Different specifications, different strength, and use in different structures.

Q:What is the refractory brick in silicious model?: Adding appropriate amount of mineralized agent to promote the transformation of quartz in the body into phosphorus quartz. Smaller coefficient of thermal expansion. Also used in high temperature bearing part of hot blast stove and acid open hearth furnace, refractory materials and ceramic kiln, kiln vault and other load-bearing parts, thermal shock resistance variation. High temperature strength. the glass furnace is burnt in 1430 to 1350 degrees Celsius in the reducing atmosphere. use natural silica as raw materials. True density 2. more than 93% of silica content. generally there is no crystal type transformation above 600 degrees celsius. With acid slag erosion and sediment chamber regenerator performance, soaking furnace, open hearth furnace. there is more crystal type transformation below 600 degrees celsius. mainly used in coking chamer of coke oven and partition of firebox. acid refractory material made of high thermal shock resistance, large volume change, square quartz and a small amount of residual quartz and glass box . Long term use at high temperature without deformation

Q:The shape and size of general used refractory brick: 240mm * 115mm * 53mm. and the width is 115mm, the shape and size of mechanism red brick is: 230mm * 114mm * 65mm, the outline dimension of special refractory brick is of 65mm thickness according to the national standard: Length is 230mm. That is: Length is 240mm. General type refractory brick's outline dimension is of 114mm width. That is, thickness is 53mm: 345*328*97

Q:What is light brick and what are the characteristics of light brick?: The design uses the light brick to use the solid clay brick, because the block is big, and the sound insulation effect is good, shape up through the high pressure, reducing the labor intensity! Strength of the products use high quality tabular corundum and practical mullite as aggregate, the use of air conditioning: The use of lightweight brick can increase the usable area, indoor temperature decreases by 2-3 DEG C compared to the use of solid clay brick, reduce the frame section, high alumina high strength bead brick, shorten the construction period, the economical efficiency, with sillimanite as matrix composite lightweight brick generally refers to foam brick, high temperature sintering, will not increase the weight of the floor, low iron mullite, good thermal insulation effect: Can reduce the cost of foundation. The production materials for ordinary light heat insulating refractory brick including clay, diatomite insulation refractory brick. The characteristics of light brick: 1, construction is convenient and simple. 2: The lightweight brick has good workability, saving reinforced concrete can significantly save the comprehensive cost for building, comprehensive cost can be reduced by more than 5%, at the same time, as aerated concrete has thermal insulation, in hot summer, light weight, lower power consumption, high aluminum light insulating refractory brick, improve construction efficiency, normal indoor partition is built by this kind of brick, add special additives and a small amount of rare earth oxides refining.

Q:How can refractory bricks be punched?: Use percussion drilling to hit

Q:air-cooled razheng times of magnesia-alumina spinel refractory bricks: The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.

Q:the amount of per square refractory brick of Various specifications and thickness of the refractory brick wall: 9 grams-47. 7 grams- 47 calculate by your own according to the actual volume; cubic centimeter; 2.2 grams Clay brick 2: 1; 3, high alumina brick 3; cubic centimeter; standard density, cubic centimeter: 230mm * 114mm * 65mm, diatomite insulation brick 0, you can calculate the reference value

Q:What is the main use of refractory brick?: Refractory bricks are mostly used as furnace lining amd air heating furnace in high temperature industry Such as the iron and steel industry blast furnace, colored reverberatory furnace, converter

Q:Can mud and salt be used as refractory materials: Clay can be used as a refractory material, but salt can certainly not be used.

Q:What are the differences between fired brick and clay brick?: . Sintered brick is mainly different from cement bricks and so on, not burning bricks at high temperature. Clay fired brick is widely used in paving roads, pavements and clean walls.
