- Q: What are the weak points of clay bricks?
- Clay bricks are clay products with Al2O3 content of 30%~40% aluminum silicate material. Clay brick is made of 50% soft clay and 50% hard clay clinker, according to the requirements of a certain particle size. After molding and drying, the clay brick is burnt at high temperature 1300~1400 degrees celsius. 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).
- Q: How to choose refractory brick
- First of all, design the refractory brick size or select the standard size of refractory bricks directly, resist high temperature, and convenient. There are many types of refractory bricks produced by refractory material factory, has heat insulation, so needless to say the country, this work is done by a furnace company . The qualified rate of loading and firing brick and other major production on the process and the final product rate is high, and the brick molding. Too much types of the refractory brick is not easy: is a refractory material factory to accept and use the same brick production models will be more to the degree of refractory brick amazing wide. Whether the furnace design companies or construction companies design certain size refractory bricks, in addition to satisfying the furnace operation and service life.Hiphotos, wear resistance. management and calculation have brought great difficulties, it must also be taken into account that whether refractory bricks produced by the refractory material factory is convenient, low temperature But for intermodulation between refractory bricks factory, redundancy of refractory factories prepare lots of brick mould, this is convenient for operation and construction. A large number of furnace design anticorrosion company design brasque, sometimes work is done by furnace construction company or furnace repair company. if each company that has its own furnace and thermal equipment designs refractory bricks suitable for themselved, it should take into account the general systematic and standard
- Q: Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
- There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
- Q: What is the problem about splintering when the refractory brick is fired?
- There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression
- Q: Characteristics of refractory bricks
- The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear?change?on?reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.
- Q: the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
- The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
- Q: 90 porous brick and ordinary shale brick, clay brick difference
- Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.
- Q: What is the proportion of lightweight fireclay bricks?
- The ingredients are mixed with water to form plastic mud or mud, by extrusion molding or casting molding, after drying at 1250-1350 Deg. C oxidation atmosphere sintering. The volume density of commonly used clay bricks is between 0.75-1.2g/cm3. In reality, the proportion is 1.
- Q: 1200 degrees inside the furnace, lay a layer of refractory brick, what is the temperature outside?
- 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: does Kyrgyzstan have the refractory brick to build tunnel kiln, whose specifications are 390,235,11, 240,120,60.
- Domestic standard brick has no brick in this specification. only can be customised. Otherwise only have 230 * 65 * 114.
