METHOD AND FACILITY FOR MANUFACTURING SEAMLESS STEEL PIPE
Document Type and Number:
Japanese Patent JPS6326209
Kind Code:
A
Abstract:
This invention concerns a process and an arrangement for the production of seamless tube. An ingot heated to the rolling temperature is pierced in a skew-rolling stand to form a hollow ingot, is later stretched into a tube bloom and is rolled out into a finished tube. In order to improve this familiar process, it is proposed to conduct the stretching immediately after the piercing in the same heat as the latter, in which case the rolled goods is stretched in the same skew-rolling stand, but with a passage direction that is opposite to that of piercing. An arrangement with which this process according to the invention can be implemented is also proposed.
