METHOD AND SYSTEM FOR PRODUCING SEAMLESS HOT-ROLLED PIPE, CENTRIFUGLESS-ROLLED PIPE AND APPLICATION OF AN EMPTY BLOCK OBTAINED BY CENTRIFUGAL CASTING

摘要

Sensitive hollow blocks or tubes are elongated in a hot-forming elongator while maintaining, if possible, the internal structure that is present or that forms immediately after casting, and thereby, in the case of suitable method management, even thin-walled tubes or tubes rolled from centrifugally cast hollow blocks can be made available to a sufficiently operationally reliable extent. As a result, for the first time, it is possible for rolled centrifugally cast composite material tubes to be made available and for composite material hollow. blocks produced using centrifugal casting to be utilized for the production of a seamless tube.
