In April, Primetals Technologies received an order from Liberty Galati for a new Multi-Purpose Interrupted Cooling (MULPIC) system and a water treatment plant that will be implemented at its heavy plate mill line in Romania. The technology provides an in-line plate cooling system designed to reach the cooling rates and temperature drops required for plates of varying product dimensions. This will expand the product range and improve the plates’ product quality.
The MULPIC technology is an in-line and integrated plate cooling system that is offered as a complete mechatronics package, combining the machinery with smart process control technology. The system comprises high precision valves with large flow range, high water nozzle density, and actuators with advanced flow control valves, crown, and edge control functions. This guarantees superior cooling performance and uniform temperature along the length and width of the plate.
The tailor-made water treatment plant consists of several pump groups installed to supply cooling water to the MULPIC machine. The installed pumps are partly frequency-controlled and can switch between different pump groups within seconds. This reduces maintenance requirements and improves the uniform cooling of the plate.
