Graphite bricks belong to neutral refractory materials, which are resistant to erosion of the slag or solvent from acid and alkali materials, as well as other chemical substances. Graphite refractory is featured with erosion resistance, slag resistance, low thermal expansion coefficient, good heat conductivity, and good thermal shock resistance. Graphite block can be used in the lining of reactive tank, storage tank, and the autoclave used in the chemical industry. Besides, block of graphite can be used in the bottom of the blast furnace.
Graphite Blocks Manufacturing Process
Carbon graphite blocks are made of carbon graphite materials. They are manufactured in the process of graphitization in the electric furnace at high temperature about 2500-2800℃. The main raw material of the graphite blocks is calcined anthracite, and the binder is pitch. Such products are produced through forming, high temperature baking, and final precision machining.
Graphite Refractory Bricks Properties
Compared with other refractory bricks, graphite bricks have advantages of the follows:
Graphite bricks save energy and fuels, because of the performances of good thermal conductivity, rapid heat transfer, and uniform heating. In addition, graphite bricks are environmental friendly, with no radioactivity pollute, because of the strong anti-oxidation and reduction performances at the temperature 3000℃ below, especially in the neutral mediums. Besides, such bricks are excellent in chemical properties and erosion resistance, for the features of low porosity, anti-scouring and anti-wear performance. As for the compressibility, graphite brick is featured with good compressibility, because of the low hardness of the graphite.
Excellent in chemical properties and erosion resistance
Good thermal properties and thermal conductivity
Rapid heat transfer, and uniform heating
High refractoriness and good thermal shock resistance
High melting point, about 3700℃
Besides the chemical and physical properties, graphite brick is also featured with excellent thermal properties, such as high refractoriness and good thermal shock resistance, so it will not crack because of the temperature change. Such product has very high melting point, about 3700℃, and with rise of the temperature, the intensity of the graphite increases too. Moreover, it has low thermal expansion coefficient, so it has stable performance and strong durability.
In addition to the properties of the brick itself, it also has other advantages during the construction, such as pollution-free, easy cleaning, excellent curing process, and long-term usage, etc.
Graphite Blocks Uses
For the properties above, graphite blocks are widely used in various industries, take the following parts for example:
Aluminium electrolysis cell
Blast furnace, etc.
