Bearing is a kind of sliding parts commonly used in mechanical industry, and its material is different from metal, nonmetal and composite materials.Learn More
1、Preheat before use. Specific operation: Before dipping into liquid aluminum, preheat for 5 minutes to 10 minutes at about 100 mm above the liquid level to avoid the impact of acute cooling on the material. In addition, before dipping into the solution, the gas must be passed first. In order to avoid the blockage of the pores on the nozzle, the gas supply can be stopped after the rotor raises the liquid level.
2、Isolate the air. Nitrogen or argon gas is injected into the purification box to isolate the external air and prevent oxidation of the rotor. Note: Nitrogen or argon must be pure.
3、Graphite rotor immersion depth. Make the strengthening sleeve about 80 mm above the aluminum liquid level and about 60 mm below the submerged liquid level, effectively increase the rotor anti-oxidation loss and erosion.
4、The transmission system is smooth. If the relevant parts of the transmission equipment are loose, the overall operation of the rotor will be affected, and it is easy to be damaged.
