  • Can natural graphite powder be made into graphite molds?

    Binderless natural graphite powder can be cold-pressed under the pressure of 5~20 MPa. The density and strength of the mold increased with increasing pressing pressure, while the porosity and appearance change after heating at 1200 ° C decreased with increasing pressing pressure.

  • How to maintain the graphite rotor?

    Graphite rotor is composed by two parts: rotor rod and impeller. Argon or nitrogen is blown into the aluminum melt through the rotor rod and impeller. The graphite rotor with high speed breaks up the argon of the aluminum melt to form many small bubbles and makes them dispersed in the metal liquid, and contacts with the bubbles to generate the adsorption principle to purify the solution. So, how do we maintain the graphite rotor?

  • What determines the service life of graphite bearings?

    The service life of graphite bearings, the service life of rolling graphite bearings is the number of revolutions (or the number of hours working at a certain speed). Definition: The graphite bearing in this life shall have initial fatigue damage (flaking or defect) on any graphite bearing ring or rolling body. But in laboratory experiments or theoretical applications, it can be clearly seen that the theoretical life of the same graphite bearings is different under the same working conditions.
