PURPOSE: To support the entire part of endless belts uniformly under static pressure and to maintain continuous casting adequately by segmenting the recesses of hydrostatic pressure supporting devices on the rear surfaces of the endless belts which face each other at a prescribed spacing and form a mold into small areas.
CONSTITUTION: Hydrostatic pressure supporting devices are provided with plural recesses 32 in array in a width direction as well. When the solidified shell 13 of an ingot is deformed so as to project the central part thereof toward the bodies 31 of the supporting devices, the spacings between the recesses 32 located in the central parts of the bodies 31 and the rear surfaces in the central parts of endless belts 18 decrease, the pressure in the recesses 32 increases and the force trying to push back the central parts of the belts 18 to the home position generate. Since the spacings between the recesses 32 and the belts 18 increase in the respective recesses 32 located in both end parts of the bodies 31, the force to be returned to the home position acts in both end parts of the belts 18 in the tendency reverse from that in the above-described central parts, whereby the self-adjusting power is provided, and the entire parts of the belts 18 are supported uniformly under static pressure.
