Product Description
hot sale high temperature resistant refractory firebrick for metallurgy
Fire clay bricks were mainly made from chamotte, flint clay and combining clay powder, being high pressure pressed and sintered in high temperature.
Low porosity bricks are made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. The bricks have very good physical and chemical properties in high temperature conditions.
Different Size Fire Clay Brick Features and advantages:
1.High refractoriness,
2.High-temperature endurable.
3.Good corrosion resistance.
4.Good spalling resistance and wear resistance.
5.Good thermal shock resistance.
6.High mechanical strength.
7.High-temperature creep rate is low.
8.Good volume stability at high temperature.
hot sale high temperature resistant refractory firebrick for metallurgy application:
They are were widely used in all parts of furnace lining for middle and small capacity furnace such as glass furnace, blast furnace, hot-air furnace, cement furnace,chemical furnace and other heating engineering equipment.

- Q: What is the difference between corundum and high alumina??
- The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.
- Q: How much is one ton of high alumina refractory brick?
- High alumina refractory brick according to the different content of AL2O3 is divided into grade, grade one and grade two, and grade three high aluminum brick, Zhengzhou Kang Hui refractories factory price in 800-1900 yuan / ton, stable quality, are exported to the domestic and foreign markets.
- Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
- Quality requirements for aluminium bricks of different grade. 2, high aluminum powder and high alumina aggregate and other materials of reasonable proportion, to reach the production requirements.
- Q: How many cubic bricks does a high alumina brick have?
- It is related to the content of aluminum in high alumina bricks.
- Q: What are the common thermal insulation materials for thermal conductivity?
- The single organic insulation material should be the best polyurethane in the field. In accordance with the production process can be divided into on-site foam polyurethane and factory prefabricated rigid foam polyurethane board. The scene is polyurethane foam isocyanate and polyol to cool (polyether or polyester) two components as the main raw materials with additives, the on-site spraying construction with thermal insulation and waterproof function of the rigid foam material.
- 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: 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: How high can aluminum bricks expand at 80O degrees of heat?
- When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
- 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.
