发明名称 PROCESS FOR CONTINUAL TUBE CASTING WITH SPHEROIDAL 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.
