  • What are the characteristics of graphite block technology?

    The smooth function of graphite is similar to molybdenum disulfide, the friction coefficient is less than 0.1. Its smooth function varies with the size of the scale, the better the degree of graphitization, the smaller the friction coefficient, the better the smoothness.

  • How to properly impregnate graphite rotors with anti-oxidation coating

    Prepare dipping tank according to graphite rotor size specification. The dipping tank can be made of various materials according to the actual conditions, but it should be made of materials with acid corrosion resistance, good sealing, can not be infiltrated by liquid, with certain hardness and good durability.

  • What problems should be paid attention to during the use of graphite rotor?

    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.
