DEVICE FOR CONTINUAL CASTING OF STEEL TUBES WITH SPHEROIDIC GRAPHITE OF CONTROLLED STRUCTURE |
| 摘要 |
The invention concerns a method and apparatus for thermally treating cast-iron pipes formed in a continuous casting die. The pipe or tube undergoes tempering by passing through a vat which is located downstream from the continuous casting die. The vat contains a continuously cooled bath of fluidized sand or the like which lowers the temperature of the tube in a uniform manner and makes it possible to obtain a very precise and homogeneous tube structure. |
