Q: Introduction of high alumina brick: Three alumina silicate refractory product with a content of two Al2O3 (48%).

Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?: All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..

Q: How many cubic bricks does a high alumina brick have?: It is related to the content of aluminum in high alumina bricks.

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 kinds of minerals are there in the five major categories of ore crystal chemistry?: Natural element minerals. Of minerals produced by an element (elementary substance). There are about 90 natural elements in the earth's crust, accounting for 0.1% of the total weight of the earth's crust. Can be divided into metal elements, mainly platinum and copper, silver, gold, etc., non-metallic elements, carbon, sulfur, etc., half metallic elements, arsenic, bismuth and so on.

Q: How much is one ton / ton of high alumina refractory brick?: The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012

Q: Are there any differences between insulating bricks and refractory bricks?: Heat preservation brick is to emphasize its heat preservation performance generally, not paying much attention to its refractoriness, but refractory brick is exactly the opposite. Different locations will use different materials, I hope we can choose carefully.

Q: Which thermal shock stability of clay brick and high alumina brick is good?: Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products

Q: What is the difference between fireclay bricks and high alumina refractory bricks?: A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.

Q: What is the difference between metal compounds and metal solid solutions?: A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.
