Product features: with high alumina brick of hot air stove USES Yang high quality bauxite clinker as main raw material, after high pressure forming, high temperature sintering, the main mineral composition of mullite, the product has excellent volume stability, low creep rate and good thermal shock resistance, are widely used in various parts of the hot blast stove.


Q: What are the specific raw materials for plastic pallets?
There are two kinds of raw materials for plastic pallets: one is polypropylene (PP) and the other is polyethylene (HDPE).Plastic pallets for logistics storage: pp+pe material, recycled material 10%;Plastic trays for food trays: food grade PP, PE, pc;Polyethylene (HDPE) has excellent impact resistance and cold resistance, and it can resist environmental stress cracking. Excellent chemical stability, good oil resistance. Water absorption and tiny, low permeability, organic vapor transmission rate is larger. Electrical insulation is good, in all frequency range, dielectric properties are extremely excellent.
Q: Density of high alumina bricks
The density of high alumina bricks is determined according to the price. The average density is between 2.3-2.5g/cm3. The higher the density, the higher the price, the higher the aluminum bricks are in the industry. More than 2.4 are required.
Q: The difference between aluminium refractory and magnesia refractory
Aluminum refractory belongs to neutral refractory material, usually refers to silicon aluminum refractory materials, such as: high alumina brick, clay brick, high alumina castable and other products, the production of raw materials is mainly bauxite.
Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?
75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
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 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: What are the specifications for bricks?
In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
Q: What is the apparent porosity of high alumina brick?
Total porosity is porosity refers to the total volume of sample porosity in the percentage of total volume of samples. Apparent porosity refers to the percentage of the total volume of openings, pores, and total specimens in the sample.
Q: How to reduce the harm caused by two times mullite in high alumina refractory material
Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
Q: Does the chimney have high acid resistance?
The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred.
