The PRH machines are used for straightening of steel plates in dimensions within the machine’s capacity. PRH machines are produced in a wide range of sizes for plate thicknesses from 1 up to 70 mm and for plate widths up to 3000 mm. The smallest plate size that can be straightened depends on the shape of the plates, but generally the minimum plate length is twice the top roll centre distance. PRH machines are equipped with 5 bottom rolls and 4 top rolls. Top straightening rolls are hydraulically and independently adjustable up and down by means of switches in the control desk. Each top roll has its own set of digital readouts showing its position. Lower straightening rolls are fixed. For more information and capacities, please see our attached brochure.
