Cheap White Aluminum Oxide Crystals Factory South Africa

This type of furnace bottom structure has no cooling facilities(aluminum oxide abrasive), poor thermal conductivity, and deep erosion, which is about 70% of the thickness of the brick lining of the furnace bottom. The blast furnace hearth of No. 2 blast furnace at Caizhunhausen Plant of West Krupp Iron and Steel Company has a diameter of 11.5 meters(brown fused alumina grit), a working volume of 2355 meters, two iron ports and 28 air ports, but with little success.

Because, after the cooling facilities are installed in the bottom of large and medium-sized blast furnaces, clay bricks can also be used for construction(aluminum oxide grit). The cost of aluminum silicate attached fire brick is only 1/3 of carbon brick, which can also meet the production requirements and save construction investment(black silicon carbide suppliers). Before 1950, the traditional clay brick hearth was dominant, generally about 0.5 of the hearth diameter.

(cheap white aluminum oxide crystals factory south africa)For example, the bottom of the No. 6 blast furnace of the US Steel Company Duken Plant is lined with super or high-grade clay bricks(white fused alumina). In order to improve the service life of the blast furnace bottom and prevent burn-through accidents, some countries have adopted the method of thickening the bottom of the furnace(silicon carbide companies). Using the integrated furnace bottom or gold carbon brick furnace bottom solves the problem.

In 1944, the Soviet Union ’s Chelyabinsk first used a clay brick-carbon brick composite furnace bottom on the No. 1 blast furnace(white aluminum oxide). Its structure was built by sticking bricks on the bottom of the furnace bottom and carbon bricks on the upper working layer. The clay bricks at the bottom of the furnace flowed out from the iron mouth(garnet abrasive). During the rebuilding, the two bricks were interchanged up and down to build the furnace bottom.(cheap white aluminum oxide crystals factory south africa)

In the 1950s, on the blast furnace bottom(white corundum), the United States, Japan, West Germany and China and other countries have successively used clay bricks (or high aluminum bricks)-carbon bricks to build a comprehensive furnace bottom, and conducted tests of different structural types. Because it is cheap to stick bricks, small blast furnaces in some countries are still in use(garnet suppliers). The total thickness of the furnace bottom is 4153 mm.

(cheap white aluminum oxide crystals factory south africa)Production practice has proved that high thermal conductivity carbon bricks are built in the hearth wall(brown fused alumina price), the lower layer of the furnace bottom and the periphery, the aluminum silicate refractory bricks are built in the middle of the upper layer of the furnace bottom, and the cooling facilities are added(green carborundum). Applications. In some cases, the furnace bottom has also burned through. The thickness of the furnace bottom is 4.8 meters.

The blast furnace is developing in the direction of large-scale(black aluminum oxide). Although the materials and structural types of the furnace bottom are different, there are still many integrated furnace bottoms, especially in the Soviet Union and the United States. Countries such as Japan and China are more common(glass bead blasting media suppliers). The bottom of the furnace is composed of two layers of clay bricks, three layers of flat bricks and one layer of carbon bricks.(cheap white aluminum oxide crystals factory south africa)

For example, the diameter of No. 5 blast furnace hearth of Fukuyama Plant in Japan is 14.4 meters(silicon carbide price). The bottom of the furnace has eroded three layers of aluminum silicate bricks, and has reached thermal equilibrium. With the development of large-scale blast furnaces, and the hearth was thick(white aluminum oxide 120 grit), the load on the bottom of the furnace is getting heavier and the requirements on the materials are getting higher and higher.

(cheap white aluminum oxide crystals factory south africa)Five layers of aluminum silicate bricks are built in the center of the upper layer of the furnace bottom(pink aluminum oxide), 2286 mm thick, and the bottom of the furnace shell is built with carbon bricks; then two layers of carbon bricks, 1295 mm thick; two layers under the cooling tube Carbon brick, 572 meters thick(steel grid). It has been produced for three years and four months, with an output of 6.8 million tons of iron. There was no overhaul for 15 years.
