ABSTRACT:
An apparatus is disclosed comprising a strand guide formed by guide plates which are supported and cooled by hydrostatic support elements. The support elements each include a cylinder and a piston which is stressed against the guide plate by pressure fluid supplied to the cylinder. The pistons are each provided with a bearing pad having a plurality of recesses each supplied with fluid at a constant rate which forms hydrostatic support for and cools the guide plates. The forces exerted by the support elements may be controlled by pressure regulating valves in the fluid supply lines leading thereto in response to sensors which sense positional shifts of the guide plates from a set point. The apparatus may also include a controller for the valves which periodically reduces the pressure of the fluid supplied to the support elements sufficiently to allow the casting to move along the strand guide.
