Low Price White Fused Aluminum Oxide Refractory Belgium

Hot blast furnace is a kind of heat exchanger with heat storage(steel shot abrasive). It can provide hot blast with certain temperature for the effective operation of blast furnace. Its air volume should be sufficient and its supply should be continuous(brown aluminum oxide grit). The production practice shows that for every 100 ℃ increase of wind temperature, the coke ratio can be reduced by about 20 kg / ton of iron, and the production increase is nearly 5%.

Recently, in order to improve the service life of the straight nozzle and save energy(brown fused aluminum oxide), the Japanese podded refractory company has used centrifugal molding machine to make double-layer refractory castable pipe lining. At present, as we all know, there are more than 190 external combustion hot blast furnaces in various countries(white aluminium oxide powder), and they are developing continuously, which affects production, and good results are obtained.


Therefore, Japan, West Germany, the United States and the Soviet Union and other countries generally use high wind temperature hot blast furnace(black aluminum oxide), the average wind temperature has reached 1100-1200 ℃, and the average wind temperature of some hot blast furnaces has reached 1350 ℃. In addition, mullite bricks are also used in the upper part of the regenerator and the parts with large temperature changes(aluminium oxide material for blasting), which affects the service life of the furnace.


The maximum static load on the lower part of the checker brick of the regenerator is 8 kg / cm(pink aluminum oxide), and the static load on the lower lining of the combustion chamber is 4-5 kg / cm. Under the action of mechanical load and high temperature, shrinkage deformation and cracks occur on the brick body(brown aluminum oxide sand). In the area of 12-20 meters combustion chamber, the largest shrinkage is due to the combined effect of temperature and load.


If only the shrinkage of refractory brick masonry itself is considered(glass beads manufacturers), the shrinkage is 0.4% and 1.1% respectively when it is used for 10 months and 4 years, i.e. with the extension of service time. For example, the temperature of furnace shell near the temperature measuring hole 25 meters above the ground of No. 1 hot blast furnace in a factory reaches 180 ~ 270 ℃(white aluminum oxide rubbing compound). The pressure on the arch foot brick of the furnace top is 0.2-2.0 kg / cm.


The shrinkage of brick masonry is also increased(white fused alumina). According to the analysis of the damage mechanism of the lining of hot blast stove, many countries attach great importance to high temperature creep property, thermal conductivity and specific heat when choosing refractories(white aluminium oxide grit). The hot blast stove is usually heated by blast furnace gas(garnet abrasive price). If necessary, high calorific value fuel such as coke oven gas or heavy oil can also be used.


For example, bpc-1 super-high alumina refractory castable is generally used as lining in the air supply system of large blast furnace in Japan(white aluminum oxide). When the lining at the tuyere or other hole lake of the hot blast stove is partially damaged, the water glass is used to fill the acid base material for repairing(white aluminum oxide crystals). If the pipe is laid carefully according to the construction procedures, the surface temperature of its shell is generally lower than 100 ℃.


For this purpose, drill holes in the furnace shell around the temperature measurement hole(white corundum), install nozzles, and squeeze 1570kg of fire-resistant pressing material with a force of 1.0kg/mark meter. After repairing, the temperature of furnace shell has been reduced to 60-90 ℃(glass bead abrasive), and the temperature has not increased after using for more than one year, that is to say, the lining repaired by refractory pressing material is good.
