to analyze the impacts of technological parameters during the process

based on the self-developed HCC slab blank caster.The results reveal that both design of the HCC and cooling rate achieved by the developed apparatus can well meet the critical conditions for formation of metallic glasses of Zr

.The results reveal influence of technological parameters to instantaneous cooling rate and solidification front position

that is

casting speed

>

casting temperature

>

casting start position to solidification front and casting speed

>

casting start position

>

casting temperature to balance state of solidification front and slab length at which instantaneous cooling rate reach the critical value.Accordingly

the optimal process parameters are presented as follows:casting temperature and casting speed of 1 080℃and 4 mm/s

respectively

and the casting start position is suggested 14mm away from the entrance of crystallizer.
