red clay brick
1) Good thermal shock resistance
2) High-temperature endurable
3) Good thermal insulation

Q: The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?: The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack

Q: What are the differences between high alumina brick and high alumina refractory brick?: with the increase of the fire temperature and other indicators, Al2O3 content is also improving. the general content of Al2O3 in high alumina brick is more than 60% .

Q: What kind of refractory brick is suitable for 24*28m rotary kiln of 5,000 tons?: Magnesia spinel brick and magnesia hercynite brick

Q: Are there any good improvement measures for the always collapse of the previous vaulted tunnel kiln built by refractory bricks?: Volume shrinkage, uneven shrinkage and expansion of part, long-term high-temperature processing crystal type changes, calcium and other substances forming the refractory brick is Magnesium Oxide. Also the temperature changes quickly, and belongs to the crystal compound, silicon aluminum, sealing material's selection should be pay attention to

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: Should refractory cement hang inner core when use carbon steel pipe make water heating hearth by self?: I think it shouldn't. There is no refractories used for circulation pipe inside the boiler, and there is how long distance between pipe and coal fire

Q: What are the advantages and disadvantages of clay refractory bricks?: The mineral composition of clay brick is mainly kaolinite (Al2O3, 2SiO2, 2H2O) and 6%~7% impurities (potassium, sodium, calcium, titanium, iron oxides). The sintering process of clay brick is mainly the process of the continuous dehydration of kaolinite and the formation of crystallization of mullite (3Al2O3. 2SiO2). SiO2 and Al2O3 in clay bricks form eutectic, low melting point silicates with impurities during sintering, and are surrounded by mullite crystals.

Q: How to prevent the refractory bricks from burning to crack?: This may result from formula. Prevent the refractory bricks from being overweight. Firstly, sintering agent should not exceed the standard, when sintering, bricks must be well piled to piled bricks, and the bricks must be dry.

Q: Are buildings allowed to use red bricks?: Is the red brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing. Also called clay brick. Red brick technical specifications are generally from 75 to 100. Ordinary fired brick (red brick) is also called standard brick. The size is 240*115*53. (mm) red colour, sometimes dark. Ordinary clay brick has a certain strength and durability, but also because of its porous and has a certain insulation, heat insulation, sound insulation and other advantages. Therefore, it is suitable for wall materials and masonry columns, arches, chimneys, floors and foundations. Old buildings use it as building materials. Invented by the Romans, many of the remaining classical structures in Europe had red brick and brick roofs and walls.
