Centrifugal Casting

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: OD60mm-OD1500mm 

wall thickness: 6mm-100mm
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. Induction melting furnace is designed with inert gas protection to avoid oxidation of the steel liquid and improve the steel quality with micro alloy. NPA has 1 electric arc furnace, 10 induction furnaces and 8 centrifugal casting machines.
