Definitions

  • This invention has for object a method for receiving and discharging bars and device with couple of adjacent parallel rotating drums for receiving bars in longitudinal advancement and discharging them by fall on underlying cooling bed in rolling mill plants.
  • the speed presently used in the steel bars hot-rolling plants is of about 35 m/sec.
  • the main cause is in the stand-off forced by the receiving of the rolling bars downstream of a well known "flying shear machine", that breaks the continuous rolled section deviating it by sending a bar on one side and a bar on the other in a known channelled rotating drums having four externally open channels on each drum, that by receiving a bar in a drum and a bar in the other, provide alternatively to discharge them downwards after rotation on the underlying cooling bed.
  • a well known "flying shear machine” that breaks the continuous rolled section deviating it by sending a bar on one side and a bar on the other in a known channelled rotating drums having four externally open channels on each drum, that by receiving a bar in a drum and a bar in the other, provide alternatively to discharge them downwards after rotation on the underlying cooling bed.
  • Purpose of the present invention is that of increasing the speed of said device without need of substantially changing its structure.
  • each drum discharging a bar at a time on the respective cooling bed underlying seat that in accordance, will shift transversely the different bars .
  • Figure 1 is a simplified cross sectional view, on the vertical-plane of a device with a double drum device according to the present invention where by 1,2,3,4 are indicated the positions of progressive forwarding of four bars in logic succession in the respective couples of channels in the two drums.
  • Figure 2 is a view of the phases in logic succession (A,B,C,B) showing how the bars are received and discharged according to the present invention.
  • Each drum as in prior art is mounted on rotating axis (51) with head motor (not shown) for its rotation for angular predetermined values.
  • Each drum (52) is internally covered by a crankcase (53) that prevents the bars (1,2,3,4) from coming out, making their downwards fall, only after suitable drum rotation.
  • the bars are sent in succession into the channels 1,2,3 and 4 later starting again from channel 1.
  • the concerned drum stops for a suitable time, in an intermediate angular position for example at 100° (Phase A Fig.2) .
  • the machine can also receive only one bar for drum (in the case of large rod sections with lower speed), in this case only one channel for drum and only two bar-brakers will be used
  • the respective couple of channels 1,2-520 are disposed in two couples one opposed to the other in each drum 52.
