- Q: How to choose the proper refractory bricks when buying the refractory bricks?
- Crack condition. 4. 6. Inspection of dimensions. Conditions of pits and swells and lack of edges or angles. The inspection of refractory bricks' appearance quality and the condition of the affecting with damp.
- Q: What materials make of clay insulating fireclay brick?
- Clay insulation bricks are general according to the different origins of raw materials, not the same
- Q: What are the main raw materials of refractory brick and runner brick?
- Types of refractory bricks are divided into low-grade and high-grade. generally, siliceous, semi siliceous and high aluminous runner brick brick have higher requirements. If it needs to contact melting in high temperature molten steel directly, then it is high alumina(the main raw material is clinker of bauxite with high alumina, corundum( brown corundum and white corundum), the refractoriness is high, lower than 1580 DEG C temperature, but the actual using temperature reaches 1630 DEG C
- Q: What to do if refractory bricks saltpeter when they are used outdoor
- Efflorescence is usually dialysised from brickwork joints, dealing with the gap is ok These white substaince inside the pan tile: Cement efflorescence efflorescence is wow cake section from light leather intestinal common disease inumiya Hua building surface, according to their different causes and manifestations, there is pan cream, white, whitening, cream, on the walls and decorative surface erosion and other names, is the change of soluble saline alkali soil, adobe, brick, cement, mortar, concrete, masonry, ceramic tile, paint and other building materials with temperature, humidity and other external environment, in a water absorption, water transfer, water evaporation process with physical and chemical changes of the original building material damage disease phenomenon, erosion degree also has the very big difference there is a common, get damp, foaming, powder, drum, hollowing, cracking, spalling, mildew and crystallization phenomenon. Cement efflorescence may have some relationship with the quality of the cement, sand, water, air, temperature, humidity, it is a common fault in building. Use cement to do the pebble shape, it also prones to the above problems: A layer of white stuff on the surface. Terms of settlement： Scrape the dust in brickwork joint, pointing again. Use special pointing agents, more resistant to corrosion, not easy to efflorescence.
- 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: th choose of different refractory bricks in the rotary?kiln
- According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
- Q: What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
- But most people use high alumina brick or clay brick, G6 refractory brick. The specific masonry location, such as G4 refractory brick, standard brick, T38, OD, T39, according to the length of your rotary kiln, many kinds of refractory bricks are used in cement rotary kiln, the specific size of the inner diameter should be calculated in detail
- Q: Are refractory bricks poisonous?
- Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive
- Q: T38 size of high alumina refractory brick
- 230*114*65/55
- Q: The harm of wet bricks used in refractory bricks
- Increase the natural protection time, increase the baking time, or water can not discharge, this will cause swelling deformation of furnace wall.
