Abstract
There is described a rotary trough type cooling bed run-in apparatus for dropping the roll bars of a steel round bar mill onto a cooling bed in an aligned state at high speed and absent the warpage associated with similar devices. Several troughs each having a longitudinal opening and an axial opening are rotatably mounted. A roll bar is introduced axially into each of said troughs following which said opening is closed off by a cover to ensure that said bar will not be prematurely ejected. As said troughs move downwardly said covers are simultaneously removed to expose the enclosed bars and these are allowed to fall downwardly onto a cooling bed.

In a rotary trough type cooling bed run-in apparatus employed for guiding a small round bar rolled by a merchant bar mill to the upper input side of a cooling bed and allowing the bar to drop in an aligned state on the cooling bed, the combination comprising:
- a plurality of rotatably mounted long troughs open at each end and arranged in serial fashion, each having a longitudinal slit and each being adapted to receive a product bar axially;
- a plurality of rotary guide means secured lengthwise to each of said long troughs each having a lateral opening extending in the same direction as said slit;
- fixed support means for rotatably supporting each of said long troughs through said guide means;
- a slit cover secured to said support means without interfering with the rotation of said long troughs and said guide means, whereby, in response to the rotation of each of said long troughs said slit is covered when said slit faces said slit covers and said slit is uncovered when said slit is not facing said slit covers;
- and
- a cooling bed having a plurality of grooves disposed below said long troughs, whereby, the product bar dropped from each of said long troughs through said slit is received in one of said grooves.
