Q7:What is the service life of your bricks?

A:The service life of different bricks is unlike.It also depends on your using condition and method.

Q: Why can earth make bricks?: Therefore, it is still widely used in masonry projects such as walls, foundations and columns. However, due to the production of traditional clay brick to destroy the field, large amount of soil sampling, high energy consumption, brick from the major, high labor intensity and low efficiency in construction, it is necessary to gradually reform and replace with new materials. Some cities have banned the use of clay bricks in buildings. Brick for sintering brick and non sintered brick in accordance with the production process; according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, slag brick and lime sand brick; according to whether the hole is divided into hollow brick, brick. In addition to clay, or as raw materials for preparation of brick by using fly ash, coal gangue and shale, which is due to their chemical composition similar to clay, but because of the fineness of less clay, so the poor plastic bricks often to be mixed with a certain amount of clay, in order to increase the plasticity. The use of coal gangue and fly ash and other industrial waste residue brick, not only can reduce the environmental pollution, saving large areas of farmland clay, and can save a lot of fuel coal.

Q: Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?: Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.

Q: Why can't build refractory brick behind the skew block?: Refractory is heat expansion and cold contraction, when it is high temperature, it will squeeze toward the center and the vault will be deformation .

Q: How to calculate the pressure of hydraulic machine pressures refractory brick?: If it is a plunger type cylinder, the pressure of a cylinder is the cross-sectional area of the piston multiplied by the pressure of the hydraulic system; if it is piston cylinder, that is the inner diameter of the hydraulic cylinder multiplied by the pressure of the hydraulic system. Adopt cm as diameter's unit, a unit of pressure is kilogram force per square centimeter, the calculated result is kilogram which divided by one thousand is ton.

Q: With what three clay brick clay brick with six holes under what circumstances?: Local material. The two kinds of pumping rate are different, the thermal resistance is different, the volume density and thermal conductivity have some differences, but also by the designer's habits, and local production, the impact of the market.

Q: What is sintered non clay brick?: According to the production process can be divided into sintered brick and non sintered brick, in which non fired brick can be divided into compressed brick, steam brick and autoclaved brick, etc., according to whether or not the hole can be divided into ordinary brick, porous brick, hollow brick.

Q: What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?: except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.

Q: What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?: The density of hand-made is not enough, it's light, while the density of machine pressure is high, it's heavy, each has their own benefits

Q: does all the refractory refer to refractory bricks when making steel?: Not only are refractory bricks, and shapeless refractory material; blowing agents, drainage sand, and oxygen are all metallurgical auxiliary materials.
