Title:

APPARATUS FOR HORIZONTALLY AND INTERMITTENTLY DRAWING OUT CAST STEEL PIECE FROM HORIZONTAL MOLD OF HORIZONTAL CONTINUOUS CASTING MACHINE

Document Type and Number:

WIPO Patent Application WO/1985/001900

Kind Code:

A1

Abstract:

Apparatus for horizontally and intermittently drawing out a cast steel piece (1) from a horizontal mold of a horizontal continuous casting machine in a plurality of cycles each consisting of a drawing operation continuing for a predetermined period of time, suspension of the drawing operation for a predetermined period of time and a push-back operation for a predetermined period of time. The apparatus comprises: at least a pair of friction feed rollers (2A, 2B; 3A, 3B); a driving device (4) for driving the pair of friction feed rollers (2A, 2B; 3A, 3B); and a damping means (12) including a hydraulic damping device (13) which is driven in interlocked relation to the driving device (4), and a throttle valve for restricting the flow rate of oil flowing out from the hydraulic damping device (13) while the cast steel piece (1) is being drawn out. While the cast steel piece (1) is being drawn out from the horizontal mold, the damping means (12) applies to the driving device (4) a damping force which is proportional to the number of revolutions of the driving device (4), whereby the cast steel piece (1) is prevented from being drawn out from the horizontal mold beyond the above-described predetermined period of time.
