Compared with prior art, the present invention has the advantages that
This hair water cooled copper plate device is compared with traditional water cooled copper plate device, due to being opened up on the end face at the not opening end of cover plate
There is the radiating groove for radiating, therefore the water cooled copper plate device of the present invention has bigger surface area, radiating effect is more preferable, energy
Enough strengthen recirculated water at same temperature and, to formwork and the cooling effect of molten metal, so as to improve in-furnace temperature gradient, improve orientation
Single crystal casting grain size qualification rate.Water cooled copper plate provided by the invention is simple in construction, simple and easy to do, but the economic benefit created is huge
Greatly.
Further, when being shaped as V-arrangement of the groove cross section that radiates, the depth h=0.3~0.5mm for the groove that radiates, the length of side
L=0.3~0.5mm, the angle on both sides is 60 ° ± 5 °, therefore can ensure that liquid metal is nonwetting with lid surface, Neng Goufang
Only liquid metal enters in radiating groove.
