MULPIC(R): In-line Intensive Cooling for Plate Mills
The In-line intensive cooling has become the most powerful process in modern plate mills in order to produce higher strength and value added grades.The key to success is higher cooling rate,better cooling accuracy and uniform cooling across the length and width.Many existing Plate Mills have insufficient cooling capability or no cooling equipment at all.These Plate Mills need to add or improve their cooling capacity in order to respond to the end customer demand.However,every plant has a unique layout and hence it is difficult to incorporate a standard machine to all these customers.This paper illustrates several design techniques that has been adopted to incorporate a standard cooling machine in to existing Plate and Plate Steckel Mills.Since 2002,Primetals Technologies has commissioned many MULPIC(R)(MULti Purpose Interrupted Cooling)machines in plate mills around the world.Until recently,most of these installations were standard MULPIC(R)machines of 24m in length.However,some of the existing plate producers are looking for performance improvements by adding high flow density headers in front of existing laminar cooling sections.This hybrid configuration provides several challenges for process control as well as engineering.In this paper we discuss these challenges and the benefits associated with such a hybrid cooling machine and the steps taken to ensure a smooth and rapid design,installation,start-up and fast achievement of the results.Many new customised design features,such as,flexible hoses,new flow control valve and hybrid cooling model have been introduced to improve performance and ease integrating MULPIC(R)in to existing systems.This enhances the product range but minimises the costs and disruption to the existing production line during installation and start-up.
