When casting is started, the head of the dummy bar is the movable inner bottom of the crystallizer, the molten copper is poured into the crystallizer to be gradually condensed into a blank shell with a certain thickness and is continuously pulled out, at the moment, the inner wall of the crystallizer bears the combined action of mechanical stress and thermal stress generated by the static pressure of high-temperature molten copper, the friction force of relative motion between the inner wall of the crystallizer and the blank shell, and the like, and the working condition of the dummy bar is extremely bad. In order to obtain acceptable billets, the basic conditions that the crystallizer should fulfil are: (1) The copper alloy has good heat conductivity so as to enable the copper to be rapidly condensed and formed; (2) The wear resistance is good, so that the service life of the crystallizer is prolonged, the maintenance workload and the time for replacing the crystallizer are reduced, and the operation rate of the continuous casting machine is improved; (3) Has enough rigidity, and particularly needs small deformation under the condition of large chilling shock heat and temperature gradient; (4) The structure is simple and compact, the manufacture is easy, the disassembly and the assembly are convenient, the adjustment is easy, and the cooling waterway can be automatically communicated so as to be convenient for quick replacement; the self weight is small, so that the inertia force of the crystallizer during vibration is reduced, the driving power of the vibration device is reduced, and the vibration of the crystallizer is stable.
