To the ingredients of refractory products(brown fused alumina bfa grade a manufaturer), at this stage due to the progress of diffusion, flow and dissolution-precipitation and other mass transfer processes, the particles are closer to the surface under the action of liquid surface tension to make the green compact, volume reduced, porosity reduced, strength Increased, sintering rapidly(aluminium oxide grit blasting vendor). Adding trace TiO2 to pure alumina products can greatly reduce the sintering temperature.

During the cooling process of mullite, mullite slowly precipitates, and the liquid phase solidifies into a glass phase with shrinkage(white aluminum oxide non-skid grit). During the cooling of silicon brick to low temperature, there is a rapid crystal transformation of cristobalite and scale quartz, and the volume shrinks(brown fused alumina for abrasive). At this stage, various reactions tend to be complete and sufficient, the amount of liquid phase continues to increase, and the crystalline phase grows further to achieve densification.


At this stage, the crystallization of the refractory phase, some crystal phases, and the solidification of the glass phase and other processes occur(white aluminum oxide sand). Silica brick is used for the bottom of the kiln fired magnesium brick inverted kiln, magnesia-chrome brick for the containment wall, and magnesia aluminum brick for the dense roof(aluminium oxide for blasting). Generally speaking, a small amount of iron oxide can be added in the production of magnesia bricks to generate a limited solid solution to promote sintering.


generally uses brick palletizing. Stacking is too high(brown fused alumina). The stability of the brick stack is poor, the temperature difference between the top and bottom of the kiln is intensified, and it is not easy to load the stack out of the kiln. The bottom of the fired silicon brick and high-aluminum brick inverted flame kiln is made of silicon brick or high-quality high-aluminum brick(white fused alumina make company), and the wall and top are built with high-quality high-alumina brick, which is called "sintering".


However, there is a fire wall in front of the combustion chamber(brown aluminum oxide). The firing temperature of other advanced refractory products can be higher, for example, pure alumina products are 1600 ~ 1800 ℃. The kiln bottom fire hole and the flue flue are built on the kiln car, and then connected to the main flue in the lower part of the kiln wall or the lower part of the kiln car. After being burned, they are pulled out from the same side(46 grit aluminum oxide blast media). They are pushed and pulled out like a drawer.


The high-temperature inverted flame kiln is equipped with an air heat exchanger in the flue to recover waste heat(brown aluminium oxide). The high-temperature flue gas generated in the combustion chamber rises to the top of the kiln along the fire vent enclosed by the fire wall, and then folds back and flows down through the brick stack to heat and burn the brick blank(fused alumina). Small high-temperature kilns can use high-quality corundum bricks and alumina hollow bricks to build dense roofs and kiln walls.


Inverted flame kiln is a batch kiln used to produce refractory products(brown fused aluminum oxide). The high-temperature flue gas flows against the direction of the kiln car, cools while heating the product, and forms exhaust gas with the gas discharged during the heating of the brick blank, and is exhausted from the pre-tropical zone to the atmosphere through the smoke exhaust machine(white aluminum oxide crystals). The bottom of the kiln is composed of a kiln car similar to a tunnel kiln.


Refractory products firing system includes heating rate, firing maximum temperature and atmosphere, holding time and cooling rate(white aluminium oxide). Disadvantages are large heat consumption, long production cycle, low output, high labor intensity, poor production environment, difficult to automate and mechanize production(arc fused alumina). There is a curved door between the kiln car and the kiln wall. The kiln car vertebrae filled with products are fired in the kiln.
