Abstract

A water-cooled centrifugal pipe casting machine includes a sector ladle tilting system, a pouring runner, a pipe mold and a pipe removing device. The pipe mold is provided to a travel system, and rotation of the pipe mold is controlled by a pipe mold rotating system. By using a servo motor driving the sector ladle tilting system, by using a parallel four-bar linkage structure tilting a sector ladle, and by using a variable frequency motor controlling the movements of a rack and a gear of a travel driving system, a constant amount of hot metal flowing out of the sector ladle per unit time can be ensured and a constant traveling speed of the centrifugal pipe casting machine are achieved. As such, uniformity of the wall thickness of the casting pipes can be ensured, the quality thereof can be improved, and materials required can be saved.
