Favorable Price Long Service Life Carbon Graphite Rotor Shaft Reduce Aluminum Content in Slag

1. Preheating before use: Before the rotor is immersed in the molten aluminum, preheat the rotor at about 100mm above the liquid level for 5min~10min to avoid the effect of rapid cooling on the material; the rotor must be filled with gas before immersing in the liquid; The air supply can be stopped to prevent the air holes of the rotor nozzle from being blocked.
2. Isolate air: Pour nitrogen or argon into the purification box to ensure positive pressure in the box and isolate the outside air to prevent the rotor from oxidizing.
3. Rotor immersion depth: The reasonable depth of the rotor immersion in the aluminum melt is about 80mm exposed by the strengthening sleeve to the aluminum liquid level and about 60mm below the immersion level, which can effectively increase the rotor’s anti-oxidation loss and erosion.
4. The transmission system is stable: the rotor and the transmission system are connected by connecting rods (tubes). The connecting rods are deformed under the action of high temperature for a long time, or the related parts of the transmission equipment are loose, which will affect the neutrality and operation of the rotor. The stability is easy to cause the rotor to break or be damaged by bumping. The argon or nitrogen gas should be pure: if the pipelines, joints and other components leak, the argon or nitrogen gas introduced into the aluminum solution will be impure, which will seriously oxidize the upper part of the rotor, and even oxidize several rotor jet holes in the lower part. This will greatly shorten the life of the rotor.
