DE1608352C - Device for guiding a walking beam system as a pull-out device for a continuous sheet caster - Google Patents

Description

Drawing is not shown in detail. The movement of the upper ends of the walking beams 3 to and from Strand is effected with the help of rollers 9 and 10.

When the crankshaft 4 reaches the lower ends of the Beam 3 pushes apart, the guideways of the projections 3 'lie at the top of the lifting beam 3 on the guide rollers 9 and 10 and these roll on them like on guides, where they continue the underlying attack surfaces 8 of the lifting beam 3 from the surfaces of the strand 1, so that a gap is created between the walking beam 3 and the strand 1.

The projections 3 'are continuously pressed against the guide rollers 9 and 10 by the springs 16. As a result, the walking beam 3 can be moved back to the starting position in which they be pressed together with the aid of the crankshaft 4 to pull out the strand 1. The walking beam 3 of the second walking beam arrangement continue the movement accordingly. The inventive Device for guiding a. Walking beam system as a pull-out device for a continuous bow caster stands out compared to the known systems, which have a lower drive at the upper end

ίο require synchronized drive by a great deal simpler and more reliable structure, which ensures high reliability and the risk largely excludes malfunctions due to the effects of temperature on individual parts of the device.
