Q: In 2016, a few of the traditional refractory materials will be able to survive: In short, the overall market of refractory enterprises is in a turbulent adjustment process, but the volume is still in place. Elimination is inevitable, as to how many can be eliminated, dare not assert.

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: 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?: 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: Corundum, high alumina and fireclay refractory difference is what: They differ in that the alumina content is different, and the content is in order: corundum > high alumina > clay.

Q: The difference between ordinary and diatomite brick refractory brick: To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.

Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?: The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.

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: How are the grades of high alumina bricks differentiated?: If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not exactly the sameFor example, European countries limit the content of Al2O3 for high alumina refractory materials at 42%.

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.
