Q:refractory bricks of fireclay
According to the preparation process, it can be divided into bricks, high alumina brick, magnesia brickand so on, such as refractory clay brick, and ordinary brick; according to the shape and size, it can be divided into standard brick and silica brick, it can withstand all kinds of physical and chemical changes and mechanical action at high temperature; silica brick can be used as high-temperature building materials and structural material to build kiln and kinds of thermal equipments. Refractory material and fused brick with a certain shape and size are called refractory brick for short.
Q:is refractory brick used around the mechanism flue?
Q:Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
Q:What's the reason of cracks in refractory bricks?
If it is made to refractory bricks,dry in the air naturally for 10 days, then put into the drying furnace, which is certainly better than the brick is put to the furnace directly, this is not easy to crack. After all, the moisture of brick will run in the air. See the semi-finished products (not crack is really no crack), but after drying, it has cracks, this is must because moisture runs quickly in a short time. If it cracks after high temperature heat treatment, the reason is very complicated, such as after high temperature burning, temperature decreases too fast, resulting in a large temperature change, then it cracks. Or in the process of high temperature heat treatment, the internal reaction is intense, and generate some volume expanding materials, resulting in cracks and so on. Mullite Petrochemical reaction, spinel reaction and so on, the reactions of a lot of materials are the volume expansion
Q:Will the heat be taken away by the refractory brick
The heat will be taken away by the refractory bricks.
Q:what is consequence of high load and soft low of high alumina refractory brick ?
softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
Q:Can common cement mortar be used to build the lining of chimney refractory brick?
No. You have used fire bricks, which shows there is a certain temperature inside, you'd better use refractory cement
Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
Just as its name implies it is a fire burning, making stove is very good
Q:Are refractory bricks poisonous?
Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive
Q:Expansion ratio of light corundum fireproofing brick
And then the appropriate drying, the using temperature 1500~1700 degrees of light corundum brick, the porosity is 70% to 80% Now, use foaming method to produce light corundum brick, 3g/, shaped idiosome with mould dry for 4 days in 60 degree to 70 degree oast, it will demoulding, foaming method and evaporating method produce light corundum brick, the thermal conductivity is 0. the containing of AL203 has difference, the corundum brick that use corundum hollow sphere to produce contain the highest AL203 Finished light corundum brick don't have accurate shape and size after firing.8 1, so products need mechanical or manual cutting after the kiln, finally, firing in 1300 degree and 1550 degree, basically still meters with water forming, just add to burn: 50~60h, because its production methods and the introduction of additives are different, the total sintering time.17W/, light corundum fireproofing brick can be made into density is 0, withstand voltage strength is 4MPa, the containing of A1203 is no more than 99%.
