Automatic Cooling bed

Used for Cooling and cross transferring the finished product towards the discharge end.

The Automatic Cooling bed consists of two major units:

  1. Twin-channel Bar receiving Mechanism
  2. Movable Rack Cooling Bed

The Twin-channel bar receiving mechanism comprise of the following:

  1. Twin water-cooled C-type channels with water-cooling arrangement.
  2. Supporting arrangement for the twin-channel and drive system.
  3. Cam device for opening closing of the pipes.
  4. Hydraulic Drive for operation of the cams.

The Twin-channel Bar receiving mechanism is used to collect the TMT bars leaving the Quenching boxes after being sheared by the Flying Shear in two strands. The twin-channel is made out of CI central box, Water cooled to prevent warping during rolling, and C-type CI channels to ensure that the bars do not come out and maintain safety of the personnel.

The opening and closing of these channels is by means of a cam-shaft and follower rollers. After collection of each bar, the bar is dropped onto a fixed CI Straightening rack mechanism one by one, from where it is carried ahead by the Movable rack mechanism. The Twin-channel mechanism is provided along the full length of the Cooling bed. For example In case of a 66 m long Cooling Bed, the twin-cannel size is also 66m long. The mechanism is installed around 300 mm above the Straightening racks.

 

Movable Rack

The purpose of the cooling bed of a Movable rack design is to uniformly air-cool the TMT bars and transporting the same in a phased manner from the entry of the cooling bed to discharge side. The front ends of the bars are also leveled at the discharge side and a fixed number of bars sent for final length cutting by cold shear and bundling. The Movable rack Cooling Bed will be of a walking beam design to ensure that the bars are uniformly positioned over the toothed racks. The cooling bed is designed considering the smallest and the maximum size of the bars being rolled and the cooling time required for the various sizes of the bar.

Rack type cooling bed design depends on Bars cut previously to given lengths, to slow them down, to transport them crosswise over a cooling surface ensuring that the rolled bars in very wide range of lengths, are kept as straight as possible, to collect the bars at the end of the cooling surface to predetermined packs matched to the requirements of the cold shear, and to discharge finally same onto a roller table which conveys the bar packs to the cold shear.
