Q:What are the application of used refractory brick pieces?
auxiliary material made of refractory bricks or refractory is not as good as that of bauxite.
Q:What bricks are used for constructting refractory bricks tunnel kiln what is the material of each burning zone brick
To reduce the cost from a professional point of view, you should have the construction team to set up the specific solution for you, be sure to keep in mind not to save blindly, the best is to use refractory brick
Q:What is the heating temperature in the test method of thermal shock resistance of refractory bricks
1, quenching (air cooling or water cooling), after the completion of the specified number of times. 2, maintain 20min, introduce the following types briefly. 3, repeated testing and record the times of the material produces macro cracks. The thermal shock resistance is shown by the times of thermal cycle of damaging half of the heated end face, quenching(air cooling or water cooling ) there are many expressions and testing methods of the thermal shock resistance, and then dry. Put the heating end surface of standard size brick((200~230mm) X (100~150 m K (50~100mm) claw)into the preheated to 1100 DEG C 50mm in furnace, quenching (air or water), then quenching in room temperature water for 3min, measured the maximum temperature of sample surface produces cracks. After the temperature of the material rises to a predetermined temperature, the ratio of residual anti-bending strength and anti-bending strength at room temperature before heat shock, after the material rises to various temperatures, measure its strength retention rate.
Q:Can red bricks be burned in tunnel kiln which used to burn refractory brick?
The raw material determines the production process; the output determines the kiln type; the technology determines the quality and quantity.
Q:What are the differences between diatomite brick and ordinary refractory bricks?
The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
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:The service life of the refractory brick of the intermediate frequency electric furnace, how long is the replacement period.
There is no standard. As long as the induction coil can be fixed and furnace lining can be built, the service life will be different. Replace it if it's broken, and there is no problem to take it apart. Buy a backup. And the textures of refractory brick are not the same in different places.
Q:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
Heat insulation
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
