Double Shaft Twin Channel
The twin channel is used to collect the TMT bars leaving the Quenching boxes after being sheared by the Flying Shear in two strands. This channel comprises of CI central box, water cooled to prevent warping during rolling, and C-type CI channels which are suspended from a longitudinal structural. The twin channel for solution to TMT bar handling at cooling bed at high speeds. Twin channels are available for bar sizes up to 40mm in India and stock speeds as high as 30 meters per second. In TMT Bar rolling mills, a twin channel system is used to safely and efficiently handle TMT (thermo-mechanically treated) bars, especially at high speeds. It's a crucial component for minimizing accidents during the rolling process by guiding and controlling the flow of bars, particularly after they've been sheared by a flying shear and passed through quenching boxes.
This carries the bar in a closed channel until the material comes to a standstill position and discharges it to the bed below automatically. This is an excellent system as it carries the bar in a closed channel, minimizing the accident hazards. Specifically, while carrying out high-speed rolling the system is an absolute necessity.
Its design features makes it possible to work in conjunction with braking pinch rolls, minimizing the length of run-in. The operations of twin channel are automated and are guided by the discharge of the rods from dividing shear. An innovative idea for cast iron centre boxes has drastically brought down maintenance time. Automated Operation, Twin channels are often automated, guided by the discharge of the rods from the dividing shear.
