Lightweight insulating brick

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

Q: What are the requirements for Rubble backfill height?: 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.

Q: What's the difference between a well type annealing furnace and a box type annealing furnace?: Box annealing furnace application: mainly used for quenching, normalizing, annealing and other conventional heat treatment equipment for steel parts. Features: 1, electric loading, high productivity, heat treatment is especially suitable for small and medium-sized parts, such as 30%, uniform temperature, intelligent digital display meter PID (pictured) automatic temperature control, high precision; 2, electric discharge loading convenient, as good; 3, door and seal the oven body is sealed automatically, without manual seal; 4, equipped with electric interlock protection device, and can prevent the fault accident due to the error. Bell type annealing furnace four bell type annealing furnace bell type annealing furnace is mainly used for annealing sheet metal in natural atmosphere and normalizing treatment of steel parts. 1, special steel, precision alloy large all fiber trolley type resistance furnace, strip, wire bright annealing. 2 、 annealing of special steel casting and forging. 3. Annealing of silicon steel sheet. 4, metal and non metal powder sintering pieces etc..

Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?: High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick

Q: How to reduce porosity of high alumina brick: High alumina brick used as refractory products in refractory material, has a great application in masonry kilns, insiders pointed out that the quality of high alumina brick general porosity and it has a great relationship! So, how to reduce the porosity of high alumina brick rate is very important!

Q: How to distinguish the good or bad of the high aluminum brick?: The general high alumina bricks used in the steel, steelmaking, hot blast furnace, electric furnace, blast furnace, reverberatory furnace, rotary kiln lining of industrial furnace in China, mainly composed of a bauxite; sillimanite minerals (including kyanite, andalusite, sillimanite etc.); synthetic material, such as alumina synthesis of mullite, corundum, etc.. High aluminum brick has good quality, high refractoriness, long life and other characteristics, is the main use of refractory brick kiln products, commonly used units can not distinguish the quality and grade of high aluminum brick right in the procurement time, caused by the high prices to buy low grade products, thereby reducing the furnace life therefore, Zhengzhou's Sindh yuan refractory material factory in here is simple to introduce how to identify the quality when purchasing brick high alumina brick.Color: in the purchase of high alumina brick, first of all to see the color, high quality aluminum brick surface smooth, yellow color white, four sides smooth, no broken angle, no cracksWeight: the weight of a block of bricks to be called, according to the standard weight level, high aluminum brick weight of 4.5 kg. Two grade high alumina brick weighs 4.2 kg, three high aluminum brick weighs 3.9 kg, the same level, the same parameters can reach this standard can be regarded as high-quality high aluminum bricks, the opposite is not up to the weight that the quality is good, if there is a crack, four angle uneven, off angle phenomenon, then substandard products, some of the above points to help to the purchaser

Q: How are the grades of high alumina bricks differentiated?: High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%

Q: Which thermal shock stability of clay brick and high alumina brick is good?: High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.

Q: What is the high temperature limit of refractory bricks and refractory soil?: Refractory bricks are stone powder and clay paste. They are fired in a kiln of 1300 degrees. The upper limit is 1500 degrees above normal pressureRefractory bricks - refractory materials of a specified shape and size.

Q: What is the difference between fireclay bricks and high alumina refractory bricks?: High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3.
