Title: Method and device in the press treatment of a paper web
IPC: D21G1/02
Filed: 1989-04-12
Abstract: Method and device in a machine for the manufacture of paper or board for heating the outer face (10 min ) of such a cylinder or roll (10) as is in direct contact with the web (W) to be pressed against said roll face. The cylinder or roll face (10 min ) is heated from outside inductively by using a magnetic field, by means of which a heating effect based on eddy currents is produced in the outer layer (3) of the roll. As the cylinder or roll face (10 min ), a relatively thin outer layer (3) of an electrically conductive ceramic material is used, in which the resistive heating effect is concentrated. The depth of penetration of the heating effect in the radial direction of the roll to be heated is restricted to a sufficiently low depth by means of the choice of the thickness of the ceramic outer layer (3) and/or of the electric frequency (f) of the induction heating. Besides on the basis of its electric properties, the ceramic material of the outer layer (3) is chosen so that the cylinder or roll face (10 min ) is given the necessary properties of strength, also in view of the thermal shock of the heating effect.
