Processing layout and matching design of key parts for water-cooling permanent mold centrifugal machine with aperture less than 300 mm were introduced to improve production efficiency of the equipment.Three work-station arrangements were designed to shorten time of the auxiliary process and accelerate production rhythm.Accuracy segmentation control was realized for cooling location and time of pipe mold by segment cooling system for centrifugal main machine to effectively decrease cooling time of the produced parts.Through the in-time feedback of current signal to adjust hydraulic mechanism

error correction control can be realized

and precision equivalent pouring of seg-ladle can be ensured.
