Quick Details of Tabular Alumina:

Super high temperature shaft kiln sintered plate corundum that takes alumina as raw material is molded by milling and drying;

on condition of quick warming and cooling in super high temperature shaft kiln, it becomes lots of tight column crystal and

the dimension of crystal is among 30-200um; there are lots of alumina corundum that has high purity with lots of closed micro-holes.

Q:What are the requirements for the performance of refractory materials?
Refractory materials should have very high refractoriness, high temperature heat load and resistance to softening, melting; with high volume stability, resistance to high temperature and heat load, volume shrinkage and only uniform expansion; high strength at room temperature and high temperature strength, high load softening temperature, under the joint action of heat load and heavy load, no loss of strength, creep collapse; Electric furnace analysis should have good resistance to thermal shock, resistance to rapid temperature changes, no crack, not flaking; with excellent slag resistance.
Q:What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?
The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.
Q:What are the new refractories? What are the features? How about their application and development?
In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.
Q:What are the applications of refractory?
Refractory materials are widely used in iron and steel smelting , glass, cement kilns, non-ferrous metal metallurgy, environmental protection, and chemical, etc. For example: For a car of 1.5 tons, do you you know how much refractory it use? The answer is: To produce top hat or other steel products, glass for vehicle windows, nonferrous metals kile aluminum and copper, plastic products of the body all needs refractory. A car of 1.5 tons needs to consume a total of 10Kg refractories.
Q:What's the classification of flameproof glass, the refractory time of fireproofing glass.
Classify according to the structure, fireproof performance and fire endurance of fireproofing glass. Classify according to the structure: Composite fireproofing glass (FFB) and monolithic fireproofing glass, classify according to fire resistance: thermal insulation fire-resistant glass(class A) and non-thermal insulation fire-resistant glass (class C);classify it into 5 levels according to fire endurance: 0.5 h, 1.00 h,1.50h, 2.00h, 3.00h.
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Adding coarse aggregate is to assure its good combination with fine aggregate. This is just the experience. You don't have to ask.
Q:What's the poured refractory material?
According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).
Q:For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?
It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned brick whose cememting agent is phosphoric acid or aluminium phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.
Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?
1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.
Q:Preparation of refractory clay
Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
