Definitions
- the subject of this invention is a method for treating a Yankee cylinder, wherein the Yankee cylinder a cylinder jacket made of steel with a
- Yankee cylinders usually have a very large one
- Diameter They are heated from the inside with steam and are difficult to produce, since very high requirements in terms of internal pressures, tightness and large diameters must be met.
- Cylinder diameter 2000 mm to 6500 mm
- Hollow shaft diameter 1000 mm to 2500 mm
- Cylinder length 3000 mm to 8500 mm
- a scraper blade abuts the outer circumferential surface of the Yankee cylinder with which the dried fibrous web is scraped off the Yankee surface.
- Cylinder surface is not excluded that it comes to the material removal of the Yankee surface. In order to reduce this material removal, it is customary to Surface to be coated with a hard material layer.
- EP 2 474 665 A1 describes a Yankee cylinder which is coated with a corresponding layer of hard material.
- Yankee cylinders used to be made predominantly of cast iron from U.S. Pat.
- US Pat. No. 4,196,689 and WO 2008/105005 A1 also already disclose Yankee cylinders made of steel.
- Cast iron (hardness 240 HB), steel laminae are thermally coated with a wear protection.
- a wire is melted and sprayed onto the Yankee surface, the resulting thermally sprayed layer has a considerably higher hardness than steel.
- the sprayed layers have a layer thickness of approximately 0.75 mm.
- thermally sprayed layer lies in its relatively low thermal conductivity.
- the thermal conductivity of a thermally sprayed layer is only in the range of 3 - 7 W / mK. Opposite points the Yankee steel jacket has a thermal conductivity of up to 45 W / mK.
- the aim of the invention is to provide a method for the
- Cylinder jacket heat treated with a laser beam and hardened
- the entire outer surface of the Yankee cylinder jacket is traversed by a laser beam, heated and thus cured.
- An inventively cured Stahlyankee thereby has a 7% higher heat transfer and allows a
- the thickness of the hardened surface layer is the thickness of the hardened surface layer.
- P355NH (DIN EN 10028-3) is well suited as a base material.
- This fine grain structural steel is characterized by a minimum yield strength of 275-460 MPa as well as good weldability and brittle fracture safety.
- Laser beam hardening can achieve hardnesses of up to 400 HB when curing by conventional means. With this new procedure, a max. Hardness of 320HB aimed at with excellent thermal conductivity in the
- the hardness of cast cylinders is in the range of 230-280 HB. It is advantageous if the surface of the Yankee cylinder is briefly heated by the laser beam to a temperature between 800 ° C and 900 ° C.
- Heat treatment is preferably a high-power diode laser or C0 2 laser used, thus heating rates of> 1000 ° C / s can be realized.
- Cylinder surface detachment of the fibrous web at the end of the drying process, and influencing the properties of the tissue produced).
- a multiplicity of depressions uniformly distributed over the mantle surface can be burned into the surface by the laser beam, thereby producing a porous surface.
- the surface of the Yankee cylinder is polished after the heat treatment.
- a grinding of the surface is usually no longer necessary.
- the outer surface of the cylinder jacket is heat-treated simultaneously with a plurality of laser beams.
- the largely finished Yankee cylinder is preferably rotatably clamped horizontally with its stub axles. About one or more laser beams, the cladding surface is heat treated. The Yankee is slowly rotated, so that the laser beam the entire
- Scope sweeps over. By moving the laser in the axial direction (parallel to the Yankee axis), the entire cylinder jacket surface can be heat treated. By using multiple lasers, the
- Processing time can be shortened.
- the treatment can be done by high power diode lasers, which have a
