  • Patent number: 10065240
    Abstract: The invention discloses metal powder for a 3D printer. The metal powder for 3D printers is 10-50-micron metal powder made by agglomerating many submicron order metal particles through a granulating process. As the metal powder is combined by submicron order metal particles, the metal powder is low in melting point and high in melting speed, so that the printing speed of the metal 3D printer can be increased and the precision of a printing member can be improved. Meanwhile, the average grain size of the metal powder is equivalent to existing atomized metal powder for 3D printers, and the metal powder has good dispersibility and conveying property, and can be suitable for existing 3D printer equipment.

  • Patent number: 10047413
    Abstract: A method for smelting magnesium quickly and continuously includes: preparing dolomite or magnesite with reductants and fluorite at a predetermined ratio, uniformly mixing the prepared ingredients to obtain pellets, and calcining the obtained pellets in an argon or nitrogen atmosphere; continuously feeding the high-temperature calcined pellets (without being cooled) under argon protection into a reduction furnace, and performing a high-temperature reduction reaction in a flowing argon atmosphere to obtain high-temperature magnesium steam; and enabling the high-temperature magnesium steam to be carried out of the high-temperature reduction furnace by an argon flow, and performing condensation to obtain metal magnesium. The present invention eliminates a vacuum system and a vacuum reduction tank, so that quick and continuous production of the metal magnesium is realized, the reduction time is shortened to 90 min or less, and the recovery rate of magnesium is increased to 88% or more.
