QingDao NPA Industry Co.,Ltd
Centrifugal Casting
    • Summary:

      The centrifugal casting machine is designed with NPA patented know-how. The casting parameter (incl. centrifugal speed, mold temperature control (automatic heating system, centrifugal acceleration rate, speed control) are programmed in PLC to ensure the consistency of the quality.
      Centrifugal casting tube sizes: OD100mm-OD1500mm
      wall thickness: 6mm-30mm

    • Summary:

      The quality of the steel is improved from the essence, and the material is mixed in a separate area. Every batch of raw material after drying kiln (heating furnace) is preheated to remove the moisture (water), reduce the oxygen, hydrogen into the smelting furnace.
      The Induction furnaces are designed environment-friendly consisting of: IGBT controlled power unit, PLC control with programmed melting process, liquid steel temperature control and gas protection system etc.
