The flow field and temperature field in the self-developed horizontal-pulling heated mould continuous casting furnace with one-inlet to for-outlets for single crystallization copper were simulated by the Fluent software of CFD

and ite structure optimization was conducted.The results show that distribution of equal-distance location structure of outlets is un-reasonable at the holding furnace

where there exists obvious turbulence of inlet copper melt on outlet copper melt at No.1 and No.3 near inlet position.Meanwhile

the un-even temperature distribution at the holding furnace can be observed

and the maximum temperature difference between the inlet and outlets reaches 5 K

and there is a larger temperature difference between outlets of No.1

No.3 and No.2

No.4.Through designing two-side symmetric and unequal distance structure

where the distance of inlets from outlets of No.1 and No.3 is increased to 198 mm

flow and temperature distribution of liquid copper in the holding furnace exhibit desirable

and the temperature difference of outlets can be ignored.
