Aluminum Silicon Carbide Carbon Refractory Brick for Ladle Application $Aluminum Silicon Carbide Carbon Refractory Brick for Ladle Application$

Aluminum silicon carbide carbon refractory brick are universal materials for the lining of molten pretreatmentequipments of molten iron tank, torpedo car, etc. The products are shaped by machine power by using dense bauxite clinker and brown fused alumina as base materials and adding high quality SiC fines and high purity flake graphite. It has the advantages of excellent slag resistance, thermal shock resistance, good resistance to mechanical erosion, abrasion resistance, etc.

Aluminum Silica Carbide Brick CNBM Made in China

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:What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The rotary kiln lining structure of rotary kiln and requirements on refractories calcining active lime according to the general output is divided into Nissan 300t, 400 t, 600 t, 800 t, 1000 t, 12000 t of kiln type, calcining zone temperature at 1350 degrees celsius. The kiln is divided into a discharge end, a cooling zone, a burning zone, a preheating zone and a feeding end, and the temperature of each section of the kiln ranges from 1000 DEG C to 1350 DEG C, and the requirements for refractory materials are different. The kiln refractory materials not only to withstand the high temperature impact, but also need to bear the material erosion, kiln rotation stress produced, so not only on the physico-chemical properties of refractory materials have strict requirements, but also for the construction of brick should be strictly.

Q:What are the high aluminum bricks made of?: The amount of refractory mud accounts for about 6% of the brick weight

Q:What is the density of a super high alumina brick and what is the price?: Of course, the transaction price, please choose refractory brick manufacturer is better.

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:How many cubic bricks does a high alumina brick have?: Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.

Q:Are there any differences between insulating bricks and refractory bricks?: The insulation performance of thermal conductivity of insulating brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better.

Q:What is the heat preservation material used in a laboratory furnace?: Thermal insulation cotton is a high-purity clay clinker, alumina powder, silica powder, chromium sand and other raw materials in the industrial furnace melting at high temperature, forming fluid. Then, compressed air is used to blow or use the wire throwing machine to turn the yarn into a fiber shape. After the cotton collector is collected, the cotton is formed into a heat preservation cotton.The high alumina brick is usually made of high alumina clinker with small amount of clay. After grinding, the high alumina brick is poured and shaped in the form of slurry by the way of gas generation or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.

Q:In 2016, a few of the traditional refractory materials will be able to survive: The other is in large enterprises and individual has the unique advantage of the small enterprises, with independent technology system, production equipment advanced, there are certain funds set up to deal with risk, timely reform, such enterprises compared to a few years ago the productivity and sales or have declined, but overall is still in the stage of production increased steadily.

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.
