How to manufacture silicon carbide furnace tubes? First, we need to confirm that silicon carbide is the main raw material, and silicon carbide is formed after high temperature. The obtained material has high temperature resistance, fast thermal conductivity, high strength, high hardness, good wear resistance, good thermal shock resistance, good thermal conductivity, good oxidation resistance and other excellent functions.
Once equipped with a special high temperature insulation cover high-end, avoid metal solution to the corrosion of the electric heating element, thereby protecting the electric heating element. Its various indicators are better than the silicon carbide furnace tubes of various graphite products, and it has good thermal conductivity and oxidation resistance. By improving the manufacturing process of zirconia based electrolyte film, experts reduce the working temperature and manufacturing costs of these materials, and strive to achieve industrialization, which is also an important new direction for silicon carbide in the future. High ionic conductivity, good chemical stability and structural stability of zirconia ceramics have been successfully studied and widely used as electrolyte materials.
The properties and sintering methods of silicon carbide furnace tubes are introduced. Silicon carbide furnace tube not only has the characteristics of high temperature strength and creep resistance. Wear resistance, room temperature strength, low friction coefficient, corrosion resistance. It can work at temperatures of 1600 and is known to have oxidation resistance in the material. Silicon carbide furnace tube has the disadvantages of high brittleness and low fracture toughness. In the later manufacturing, the toughness and strength can be improved by adding fiber, whisker and particle.
Silicon carbide is a very good corrosion resistant material, we can use it to make furnace tubes and other products. When silicon carbide is used to manufacture furnace tubes, there are a variety of sintering methods such as low burning, high fever, closed manufacturing, which can be selected according to the actual processing environment to improve efficiency. Hot pressing and high temperature isostatic pressing can produce high density silicon carbide furnace tube, sintering temperature between 150 ~ 2100℃. Silicon carbide is difficult to make complex shapes and high cost products. Silicon carbide reaction sintering is silicon and graphite powder in a certain proportion of the heated green to produce -SiC. This method produces silicon carbide with low combustion temperature. However, some of the free silicon remains in the green billet, so the lining manufacturer believes that this limits the high-temperature mechanical properties and its application in strong acids and bases.
Regarding the process movement of the silicon carbide furnace tube, after the production of the silicon carbide furnace tube, if it is transferred out of the process slot, it is nothing more than a very damaging problem. How can its integrity be guaranteed from such an environment. The produced silicon carbide furnace tube is placed in the tube groove at the front end of the counterweight plate, and the furnace tube is fixed through the connection of the binding tape and the buckle. Attach the removed fastener to the other compression plate fastener. The fixing piece at the lower end of the rope is connected with the fixed groove set on the surface of the counterweight plate, and the pulley is lifted to a suitable height through the switch operation. The front end of the electric box of the locking rod is removed, and the slide rod is passed through the connection, and the counterweight plate is fixed on the pillar, which plays the role of conveying more furnace tubes, and the efficiency is increased by two times. In this way, the operation is convenient, multiple groups of endurance plates are set up, and the furnace tubes can be loaded using the tube groove set on the endurance plate, which improves the conveying quantity of the furnace tubes and the conveying capacity of the furnace tubes. A non-slip pad that can be installed in the tube groove is used to protect the furnace tube.
