ConviTec casting coolers CGK are used for continuous and precise cooling of your casts which can then be supplied to manual or mechanic handling. Gentle cooling avoids casting faults and ensures a constantly high quality of the casts at optimum flow-through times. The casting coolers are designed for three-shift operation. ConviTec casting coolers consist of vibrating conveyors with slider-crank mechanism and are designed with a vibrating or stationary hood.

The conveyor trough is wear-resistant and replaceable. Vibrating conveyor trough and hood form the cooling tunnel which can be variably arranged in a linear way or combined with curves. As two-mass system the vibrating conveyor secures the transport of the casts through the cooling tunnel regardless of their load. A frame supported by compression springs reducing the dynamic foundation loads complete the system. Frequency converters control the drive motors. The cooling tunnel is supplied with cooling air by ventilators. For effective cooling a computer-controlled nozzle system sprays water into the cooling airflow systematically. The user is supported by plant visualization of the fully automatic control incl. status display, error messages and maintenance instructions.

Optimal supply of the casting cooler is an essential condition for precise cooling. The cooling airflow is led over the hot casts in counterflow. In the further cooling process, the casts are cooled down to the requested final temperature by evaporative cooling. If you want to determine the cooling behavior of your reference casts, we will offer you the possibility of a test setup with cooling tunnel.
