Brown Fused Alumina Oxide Wholesale Suppliers Taiwan

Rotary kiln type waste incinerator is a kind of heat treatment equipment for 80 grit aluminum oxide incinerating waste (including domestic waste and medical waste), which fully guarantees the environmental protection requirements for the stabilization, safety, reduction and harmlessness of medical waste. The 100 grit aluminum oxide media brick is made by mechanical pressing and fired between 1450% ~ 1700%.

The temperature in the rotary waste incinerator is 1400 ℃ ~ 1600 ℃, and the local temperature can reach 1700 ℃: the fine grit aluminum oxide slag in contact with the hot surface in the incinerator includes Na2O, K2O, C1?, K2SO4, etc. the basicity is 0.3 ~ 1.5: the rotary mode of the rotary kiln is positive and negative swing. The atmosphere in the 1200 grit aluminum oxide furnace is constantly changing; the type, water content and acidity of medical waste are greatly changing.


At present, the refractories used in the rotary incinerator are magnesia chrome brick, pink corundum brick, high alumina brick, silicon carbide brick, etc., but due to the uncertainty of atmosphere, service temperature, calcium silicon ratio in slag and the variety of garbage, even the 80 grit aluminum oxide blasting media refractory brick with better performance is difficult to achieve its expected effect.


brown fused alumina brick consists of 10% ~ 30% CR203, 3% ~ 6% Zr02 with particle size < 0.1mm, 0.5 ~ 4.0mm with particle size of 62% ~ 87% Al203 (220 grit aluminum oxide blast media) and 0.2 ~ 0.4mm with particle size of 0.2 ~ 0.4mm. When it is used at a temperature as high as 1700 ℃, its structural elasticity and corrosion resistance are still very good, and at the same time, it is in line with the development trend of modern medical waste and domestic waste treatment. 


In the furnace with severe thermal shock and high operating temperature (1600 ℃), the brown aluminum oxide material is suitable for use. Chromium oxide brick will continue to be used as incinerator lining due to its excellent slag erosion resistance, but its high density and strength lead to poor toughness of the 120 grit aluminum oxide harbor freight material, so the material has poor structural spalling resistance.


The brown aluminium oxide open porosity is between 9% and 18%, the modulus of elasticity is less than 3000mpa, and the value of temperature cycling stress is more than 30. Refractory materials are required to have strong slag erosion resistance, permeability, high strength, erosion resistance, wear resistance and thermal shock resistance to adapt to the impact of 240 grit aluminum oxide mechanical stress and thermal stress.


The introduction of white alumina microcracks in the material can balance the gap between the corrosion resistance and spalling resistance of the material. Refractory bricks used in rotary kilns burning medical waste and domestic waste must be able to be used for slag. Most of the 180 grit aluminum oxide waste incinerators are equipped with water-cooling structure. SiC castables are ideal masonry materials because of their high thermal conductivity.


Their use in other parts of the waste incinerator will also become an important direction of black corundum refractory materials for waste incinerators. Chromium free refractory for MSW incinerator will continue to be the focus of research. 70 grit aluminum oxide blast media brick has good corrosion resistance, which is especially suitable for rotary incinerator with acid and alkali corrosion.
