The twin channel is used to collect the TMT bars leaving the Quenching boxes after being sheared by the Flying Shear in two strands. These channel comprises of CI central box, water cooled to prevent warping during rolling, and C-type CI channe ls which are suspended from a longitudinal structural.The closed C-type channels ensure highest level safety during the operation. This is an excellent system as the bar is carried in the close channel , minimizing the risk of accident. It is the most desirable feature in a high speed rolling system.High Speed Bar Collection System: In case of higher capacity mills,where he finishing speed of the bar is high, the twin channel is replaced with a high speed bar collection system;a drop wall system or a rotating twin channel which can receive more thanone finished bar simultaneously.
