Definitions
- the invention relates to a method according to the preamble of claim 1.
- the invention also relates to a roll according to the preamble of claim 5.
- the roll of a paper machine according to the invention is in turn principally characterized in what is stated in the characterizing part of claim 5.
- the variation of the stiffness of the shell and its need for balancing are substantially reduced because the shell body is not turned on a lathe, but, instead, after a roll blank has been produced out of a sheet by bending, the shell is first covered by a coating and turned only after this.
- the errors in shape are passed to the coating as thickness variation and, as the modulus of elasticity and the density of the coating are lower than those of steel, both the variation of the stiffness and the unbalance of the shell are substantially reduced.
- the coating is used, for example, in a dryer section a material that withstands high-temperature conditions.
- the coating is selected such as to have a low stiffness and a low density, i.e. the density and the modulus of elasticity are low.
- the invention can be applied to roll blanks made of planar sheets by bending as well as in connection with centrifugally cast rolls.
- the thickness of the wall is measured and its shape is determined accordingly such that the difference in stiffness is as low as possible.
- the coating can be applied to the surface of the roll by rotational casting or by vulcanizing, after which the roll is machined to a desired shape and to a desired surface quality.
- the invention is most suitable for use in connection with guide rolls and nip rolls having a low nip load, such as, for example, a reeling drum.
- Figures 1A and IB show a schematic comparison of differences in stiffness of a roll according to the invention and a roll produced by turning.
- Figures 2A and 2B show a schematic comparison relating to the eccentricity of the centre of gravity when using a roll according to the invention as compared with a roll produced by turning.
- Figures 3 A and 3B show a schematic comparison of the principal inertias of a roll made according to the invention and a roll produced by turning.
- a roll shell is bent out of a sheet blank into tubular form and its longitudinal seam is welded, and after that the shape of the tubular roll blank is measured and corrected, when needed, such that the difference in stiffness is as small as possible.
- the roll is coated by providing, for example, by rotational casting or vulcanizing, the surface of the roll with a coating the density and the modulus of elasticity of which are considerably lower than the corresponding values of steel.
- the coating is machined to a desired shape and to a desired surface quality, after which the roll is ready for use and its stiffness difference and eccentricity of the centre of gravity are substantially smaller than those of a roll produced by means of known methods, as will be clear from the following series of figures and, moreover, the difference in principal inertias as a function of the diameter and the wall thickness of the roll is small.
- the modulus of elasticity of the coating is 10 - 5000 MPa, preferably 10 - 4000 MPa, and its density is 0.9 - 3 g/cm 3 , preferably 0.9 - 1.5 g/cm 3 .
- the coating material is, for example, polyurethane, ebonite or an epoxy composite.
- Figs. 1 A and IB show a comparison of the differences in stiffness of a roll produced in accordance with the invention and a roll produced by turning when the out-of-roundness of the blank is 1 mm.
- Fig. 1A shows a roll produced according to the invention, wherein ⁇ I is 0.2 %, ⁇ I is I, - 1 2 / 1 2 • 100 %, and I- is on the horizontal axis and I, is on the vertical axis. In the case shown in Fig. IB, ⁇ I is 0.61 %.
- the diameter of the roll was 800 mm and the thickness of the wall was 35 mm.
- the difference in stiffhess ⁇ I of the roll produced according to the invention is clearly smaller.
- Figs. 2A and 2B show a comparison concerning the eccentricity of the centre of gravity when using the method according to the invention and a roll produced according to it or when using a roll made by turning, as known in prior art.
- the eccentricity E of the centre of gravity 0.21 mm
- the eccentricity E of the centre of gravity 4.83 mm.
- the outside diameter D u of the roll 810 mm
- the inside diameter D of the roll 800 mm
- the thickness s of the wall of the roll 35 mm
- the eccentricity e of the blank 1.0 mm.
- the eccentricity of the centre of gravity of the roll according to the invention is clearly smaller.
- Figs. 3A and 3B schematically show the difference of principal inertias as a function of the diameter and the wall thickness of the roll when the out-of-roundness of the inside bore is 1 mm and the difference in per cent (%) of the principal inertias is on the Y-axis, the diameter of the roll in millimetres (mm) is on the horizontal axis and the thickness of the wall of the roll in millimetres (mm) is on the Z-axis.
- Fig. 3A shows the values for a roll produced according to the invention
- Fig. 3B shows the values for a roll made by turning it on the outside as known in prior art. Considerably smaller differences are attained for the roll according to the invention.
- the technique according to the invention provides substantial advantages in the balance and stiffness asymmetry of the roll over the prior art arrangements.
