refractories insulating bricks mullite bricks

New type quality thermal insulating refractory. It contains alumina 50%-85%, and has mullite (3Al2O3.2SiO2) as major phases and binder phase. Working temperatures are from 1350° C to 1700° C.

Features:

1). High strength as containing high temperature structure
2). Low creep rate at high temperature
3). Low thermal expansion rate
4). Strong resisting chemical erosion performance.
5). Fine resisting thermal shock performance.
3. Property (See below table)

Q: What are the high aluminum bricks made of?: It's OK to use corundum bricks and alumina hollow ball bricks to build a furnace,

Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?: The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)

Q: How to make refractory bricks and boiler wall adhesion more firm?: If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.

Q: Can high alumina brick resist carburizing?: The key is to look at the content of Fe3O2 metal oxides (so-called anti carburizing brick generally refers to the content of Fe3O2 less than 1% clay brick and Gao Lvzhuan) just a photo shoot, out for everyone to see, high alumina brick common in reductive atmosphere has been chalking up.

Q: What are the requirements for refractory materials in heat treatment furnace?: The structural strength of high temperature is evaluated by loading softening point. Load softening point is that under certain pressure (2 kg/ cm 2 = 0.2MPa) under the condition of heating rate to heating, measured the sample deformation (deformation for the original sample 0.6%) temperature. This temperature is called the softening point of the refractory. Sample size is Phi 36 x 50mm.

Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?: High alumina brick clay brick up to 1700 degrees above 1500 degrees -1750 degrees of magnesia brick and magnesia chrome brick 1500-1650 degrees, I is the production of clay brick, brick my temperature at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it

Q: What's the weight of the refractory bricks?: Referred to as refractory brick. Refractory made from refractory clay or other refractory material. Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick, refractory insulating bricks (Rong Zhuzhuan);

Q: Which thermal shock stability of clay brick and high alumina brick is good?: The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.Thermal shock stability is much better than clay brick.

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.

Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.
