| 摘要 |
The invention relates to a process for manufacturing a seamless hot-finished tube of steel with reduced capacity for deformation, especially roller bearing steel, wherein a pretreated and degassed and deoxidized molten steel is continuously cast in the required chemical composition and, after separation from the strand, the continuously cast bar, divided into insertion lengths, is subjected to forming. According to the invention, the insertion length is heated to forming temperature and fed to a tube-machine without any prestraining, i.e., in the cast state and without heat treatment (diffusion annealing).
