Aluminum Oxide Blast Media Wholesale Suppliers Belgium

At present, the life of the shaft furnace is short(80 grit aluminum oxide blasting media), only 1-3 years, which has a lot to do with the combustion chamber, which is determined by the harsh working environment of the combustion chamber. The combustion chamber is subjected to a high temperature of 1100 ~ 120 ° C and a pressure of 10 ~ 20kPa(white fused alumina for refractory). If the quality of the masonry is not good, the masonry will crack, it is easy to leak air and fire.

The existing bottom frame of the combustion chamber is freely placed on the concrete platform(100 grit aluminum oxide media), the surface of the platform is rough, and the friction caused by thermal expansion is very large. The combustion chamber is not only operated under positive pressure, it can withstand a certain pressure, but it is also easy to burn through(brown aluminium oxide 24 mesh). Therefore, the choice of wind guide wall material, grid hole size and hole wall thickness are all important.

In addition, the combustion chamber is also subject to the horizontal thrust of the arch feet and the side pressure of the furnace wall gas(1200 grit aluminum oxide). The shutdown of the shaft furnace also caused some damage. Therefore, the combustion chamber may sometimes burn through and seriously affect the normal operation of the shaft furnace(brown aluminum oxide sandblasting). Pressure can not meet the process requirements for sintering pellets, and consumes less power.

The combustor combustion chamber is generally built into a 60 ° vault. Due to the existence of the vault, a certain level of thrust is generated(46 grit aluminum oxide). The heavier the vault, the greater the horizontal thrust. The light furnace is operated under positive pressure. Gas is injected into the combustion chamber at a certain pressure for combustion(white aluminum oxide grit). The hot exhaust gas generated is sprayed into the furnace hearth from the combustion tunnel.

A weak link in the shaft furnace is the combustion chamber(white fused alumina). It can be seen that the combustion chamber is not tightly sealed, and it will not form enough. The shaft furnace has been in a production state for a long time, and the combustion chamber is also in an off-temperature state(low sodium white fused alumina). The calculation shows that the gas pressure generated by the side wall is very large. Compared with the two, the former occupies less land, has no noise.

The refractory bricks expand to a certain size and stop, relatively stable(white aluminum oxide). However, if the furnace shutdown occurs, the temperature of the combustion chamber will drop, especially to room temperature, and the masonry will naturally shrink. When the shaft furnace is turned on and off, the masonry will expand and contract(brown aluminum oxide 16 grit). Repeated several times, especially the arch foot and the vault will burn through, so it is easy to cause the top masonry to crack.

Therefore, to ensure the longevity of the combustion chamber(white corundum), it is important that the masonry meets the requirements and is well sealed, and that the operation rate of the shaft furnace is improved, which is very important to extend the life of the combustion chamber(white aluminium oxide super fine). To sum up, the combustion chamber is a weak link of the shaft furnace, and under a high temperature for a long time, its working environment is relatively harsh.

The wind deflector wall is another weak link in the shaft furnace(aluminum oxide blast media 60 grit). It is supported by a metal water beam below it. It is often subjected to high temperature and dust-containing airflow, and it also needs to bear the side pressure of the charge. Therefore, the working environment of the wind deflector is also very bad(aluminum oxide 30 or 40 grit). The joint between the water beam and the masonry, especially the masonry at the lower 1m, is most likely to fall off.
