Q:What causes breakage of refractory bricks?
Refractory brick is a non metal mineral products can be used in the high temperature of 1550 DEG C under belongs to a class of inorganic, used in high-temperature furnace lining materials as protection kiln, which causes damage, usually have these points.Furnace temperature is not clear, there is no corresponding choice of refractory bricks.Physical impact, abrasion and erosion cause damageChemical factors, especially chemical industry, should be made of refractory bricks, which should be resistant to penetration and erosionIV: products from the factory when the factory did not pass the quality inspection standards
Q:What refractory material does cupola lining use?
Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
Q:The difference between ordinary and diatomite brick refractory brick
Insulation products made from diatomaceous brick and porous diatomite. The main raw material is natural porous diatomite, and then a small amount of clay and fuel are added. The volume density of diatomite brick was 0.7g/cm3, compressive strength at room temperature is 1 ~ 2MPa, the coefficient of thermal conductivity at 400 C for 0.13 ~ 0.20W/ (M - K), the apparent porosity is greater than 70%, the coefficient of thermal expansion (1280 degrees) 0.9 x 10 - 6 DEG -1, refractoriness is greater than 1250 DEG C. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius. Mainly used in industrial kilns and other thermal equipment, thermal pipes insulation materials, generally withstand the hot surface temperature of about 1000 degrees celsius.
Q:What's the price of high alumina refractory bricks?
The price of high alumina refractory bricks varies greatly according to the content of AL2O3.
Q:What is the difference between T3 refractory bricks and high alumina refractory bricks?
The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)
Q:What are the alloy wear resistance materials?
KNMn19Cr2 (patent) high manganese alloy (ZGMn13Cr2MoRe), super high manganese alloy (ZGMn18Cr2MoRe); two: anti-wear chromium cast iron series: such as high, medium and low chromium alloy cast iron (Cr15MOZCu); three: wear resistant alloy steel series: such as, low and high carbon multi metal combined steel (such as ZG40SiMnCrMO and ZG35Cr2MoNiRe); four: ADI (ADI) series; five: all kinds of composite or gradient material and hard alloy materials, nano KN alloy (patent product): such as chromium carbide composite (Cr2C3+Q235), high-energy ion osmosized tungsten carbide materials (WCSP), high toughness of cemented carbide (YK25.6), KN999 nano alloy (Beijing Naimo patent) etc.;
Q:How to reduce the harm caused by two times mullite in high alumina refractory material
Prolong the sintering time and adjust the aluminum content of the high alumina brick.
Q:Can high alumina brick resist carburizing?
Louzhu can use heavy impervious material, it is neither high alumina brick nor mullite, this product can resist seepage and have good compressive strength
Q:What are the common thermal insulation materials for thermal conductivity?
The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
Q:What are the characteristics of high alumina bricks?
High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining. High R.U.L, low creep high alumina brick with high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials.
