Low Price Aluminium Oxide For Blasting Factory South Africa

The bottom of the air-cooled furnace is made of carbon ball materials between air ducts(20 mesh aluminium oxide grit). After leveling, four layers of carbon bricks are laid. The total thickness of the furnace bottom is 3500 mm. The hearth slurry is made of carbon brick with a thickness of 991mm and a tuyere area of 914mm(white fused aluminum oxide refractory). In addition to metal iron, iron oxide or iron carbide is also formed in the damaged part, which causes the damage of carbon brick structure.

If it was ignited in November 1978, the maximum daily output is 8741 tons(brown fused alumina), put into operation for 14 months, iron production is nearly 4 million tons, and the equipment operates normally; the hearth diameter of the blast furnace is 12192 mm, furnace capacity is 3293 m, and the total thickness of the bottom of the air-cooled all carbon brick furnace is 3315 mm(brown fused alumina micro). Blast furnaces in American countries usually use full carbon brick bottom.(low price aluminium oxide for blasting factory south africa)


In order to enhance the heat transfer effect of furnace bottom, graphite brick is generally used as the cooling layer at the bottom of large and medium-sized blast furnaces in Western Europe(brown aluminum oxide). The thermal conductivity of the carbon brick used in the furnace is 4.73 kcal / m · h, then the carbon brick is fully paved, and the total thickness of the furnace bottom is 2.4m(aluminum oxide blasting grit). In addition, a layer of graphite brick cushion is built near the air-cooled part of the furnace bottom.


(low price aluminium oxide for blasting factory south africa)Three months after the furnace was put into operation, the lining at the bottom of the furnace reached a state of heat balance(brown aluminium oxide), and the solidification line of molten iron remained relatively stable, that is, the erosion had basically stopped, and the use effect was good. The blast furnace was opened on May 18, 1973(white aluminium oxide blasting media), and a minor repair was carried out due to the damage of the lining at the waist and the lower part of the furnace body.


A layer of 50mm thick graphite brick shall be laid at the bottom of the furnace bottom(glass beads manufacturers), and then four layers of carbon brick shall be laid; the furnace wall from the hearth to the air outlet shall also be laid with 1000mm thick carbon brick, and the rest furnace walls shall be laid with 42% and 35% A12O3 bonded bricks(brown aluminum oxide grit). On June 25, 1979, the furnace was shut down for overhaul, with a total iron production of 8.06 million tons, its isotherm has exceeded two layers of carbon bricks.


That is to say, the bottom of air-cooled all carbon brick furnace with graphite brick cushion is safe and reliable(garnet abrasive price). D. the large and medium-sized blast furnace generally adopts a comprehensive furnace bottom, and absorbs the experience of Western Europe and other countries(brown alumina abrasive). Since the furnace was put into operation, due to the poor construction of carbon ramming materials around the cooling air duct, poor heat dissipation and deep iron erosion.(low price aluminium oxide for blasting factory south africa)


In 1070, all carbon brick bottom was used in blast furnace in China, with a total thickness of 3100mm(glass bead abrasive). The furnace has been used for about 10 years, and the erosion is more than one meter. It has reached the state of heat balance, and the erosion has basically stopped(white corundum price). The carbon brick at the bottom of blast furnace in foreign countries is generally processed and pre built in the factory and transported to the site, then the number of people is matched.


(low price aluminium oxide for blasting factory south africa)Generally, the carbon brick at the bottom of blast furnace is laid flat(steel shot abrasive). In order to prevent floating, it can be locked, staggered or wedge-shaped. A layer of graphite ramming material cushion is rammed in the furnace bottom steel plate, and a layer of graphite carbide brick is built, and then the clay brick with A12O3 content of about 40% is used to build the working layer(white fused alumina abrasives). For example, the working capacity of L Gaoyuan is 3680m, and the hearth diameter is 13.6m.
