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: 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: How to test the aluminium bricks of high alumina refractory bricks?: Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard

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: 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: Use of high alumina refractory bricks?: Because of the high Al2O3 high aluminum products, low impurity content, the formation of fusible vitreous body less so than the clay brick high load softening temperature, but because mullite crystallization has not formed the network organization, so the load softening temperature is not high silica brick.

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?: Sigma phase belongs to Affirmative system, there are 30 atoms in the unit cell, two element alloy, sigma phase formation is related with the following conditions: (1) the atomic size difference, phase difference between the maximum sigma atomic radius of a tungsten cobalt, the atomic radius difference is 12%. (2) there is a set of cubic lattice elements (coordination number 8), and another component is face centered cubic or dense six square lattice (coordination number is 12). (3) appear in "average number of races" (s+d layer electron number) in the range of 5.7 ~ 7.5. The region of the presence of sigma in the two - element alloy is shown in table 3. In the three element system, the concentration and temperature range of the formation of the sigma phase are affected by the addition of third components. Usually in chromium stainless steel in Fe Cr phase, in Fe - Cr - Mn three yuan, sigma phase iron chromium and chromium can form Mn two element, when the addition of manganese in stainless steel, will promote the formation of sigma phase, and stabilizes the wide temperature range. Many of the Fe Cr alloy elements. The phase temperature range increases. In less than 820C stable Fe Cr phase, silicon promotes the formation of D phase and the stable temperature increased to 900 to 960 DEG C, manganese and molybdenum can improve the temperature stability of sigma phase to 1000 DEG C.

Q: What should be used as binder for making high alumina bricks?: In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.

Q: High alumina brick 80 with which high aluminum cement?: In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.
