General Information of Low Porosity Fireclay Brick DN10

Our corporation produces a comprehensive range of Low Porosity Fireclay bricks, with 30% to 55% alumina content, all of these bricks exhibit excellent performance.

Our Low Porosity Fireclay bricks are the final result of blending excellent calcined flint clay and calcined bauxite, with cutting-edge technology, adding superfine powder, after mixing, drying, forming, in the high temperature shuttle kiln. We ensure you that the Fireclay Bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Q:what effect does big mortar joints of the boiler refractory brick have on the boiler?
The ventilation leakage。 Now the larger boilers are generally used refractory pouring material one-time pouring, the arch is easy to collapse . 2, shrinkage and expansion of brick will make the bricks fall. 1, do not use the refractory brick. too large seam will effect the tightness of furnace wall , and the water wall is easy to form dew and be corroded and to leak smoke.
Q:can diatomite brick be used as thermal insulation refractory brick?
yes, it has good thermal insulation the raw material is cheap, diatomite brick is a kind of thermal insulation refractory brick with good performance.
Q:What is the refractory temperature of refractory bricks?
First look at the used parts of refractory brick, anti stripping performance, these are the most basic performance factors, the refractory temperature of high alumina brick is 1770 -1790 degree, the refractory temperature of clay brick is 1380-1570 DEG C, record the anti acid corrosion data of refractory bricks, the compressive strength of refractory bricks, at the same time, you should analyze each part of the furnace pH index and sintering temperature of working. When purchasing refractory bricks, you need to pay attention to many factors, high temperature creep property, softening temperature under a fixed load, 6548, volume stability at high temperature. Because the production of the product is affected by the weather and fuel energy, etc.. 186, select the suitable refractory bricks
Q:how to test the high alumina refractory brick mixed alumina?
The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
Q:Is fireclay brick acidproof? Does clay brick anti corrosion when it's used to build chimney lining?
Refractory bricks anti acid and alkali after high-temperature calcination, and anti-corrosion won't be a problem
Q:what is application of high alumina refractory brick?
reverberatory furnace 1, close to the neutral refractory, but because mullite crystallization has not formed the network organization, so the load softening temperature is not higher than silica brick. the refractoriness of high alumina brick is higher than fireclay brick and semi-silica brick, mainly used in blast furnace, nozzle brick,etc. it is up to 1790 C~ 1750, can resistance to acid slag and alkaline slag erosion. hot blast furnace, blast furnace, high alumina brick are widely used for producing open-hearth furnace regenerative bricks, because it contains SiO2, low impurity content, which belongs to high-grade refractory materials, electric furnace. 2, plug head used in pouring system . In addition. 3, because high aluminum products contains more Al2O3, forming less fusible vitreous body, so the high load softening temperature is higher than clay brick. because rotary kiln lining, slag resistance of high alumina refractory brick contain more Al2O3, so the ability of anti alkaline slag is weaker than anti acid slag. so it has a wide range of application. high alumina refractory brick due to the following performances
Q:Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?
refractory castable integrally casting
Q:The difference between fireclay brick and refractory cilica brick in the application.
Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
Q:How to adjust the temperature in the 160 meter tunnel kiln?
Tunnel kiln can be attemperated by burning products, this will not affect the firing of different products, and can burn back processing products.
Q:Can refractory bricks be used to pave roads or build a wall?
Refractory bricks are used to build a house, no problem
