Frame refurbishing for optimal system functioning
CalFrame involves overhauling the frame in the super calender for uniformly good and reproducible paper quality. Maintenance is simplified due to replaceable wear bars.
Frame refurbishing can deliver a decisive and reliable contribution to the productivity and efficiency of super calenders. Based on an actual measurement of the sliding and installation dimensions in the bearing guide system, the dimensions of the frame guide and the bearing guides are re-determined. On all rolls that execute vertical movements (center rolls, top and bottom rolls), new bronze slide bars are installed to the front surface. The frame guides are smoothed and a re-measurement of the bearing guide behavior and nip imprints for checking the rebuild is carried out.
