摘要
Molten metal, esp. steel, is fed into a sealed chamber in which gas pressure is used to drive the melt vertically upwards through a mould located below extn. rollers; and an electromagnetic inductor subjects the melt in the mould to centrifugal force to form the tube. The speed of rotation of the melt in the mould, and the extn. speed, are pref. adjusted to control the wall thickness of the tube blank. The pref. plant consists of a chamber contg. a ladle for the melt, which is driven up a vertical casting pipe into the mould; and a microcomputer is employed to control the process parameters. Used for casting steel and stainless steel tube blanks with low impurity content.
