Definitions

  • the invention relates to a heatable calender roll with axially parallel channels provided below its outer surface for the throughput of a thermal medium causing the heating and with at least one flange pin connected to the roll body.
  • Such heatable calender rolls are used in particular in the paper, rubber and plastics industries; in some cases of considerable length, they are to be kept mechanically extremely stable due to the narrow tolerances of their lateral surfaces, and for procedural reasons they are, likewise within narrow tolerances, at temperatures which are considerably above the ambient temperature, for example in the range of 200 ° C. to heat up.
  • rollers originally used, along with their pins axially drilled through, have not proven themselves even if the bore in the area of the roll body is widened:
  • the thermal medium is not defined here, the low flow rate occurring within the roll body affects the heat transfer, and that remaining relatively large wall thickness results in a strong hysteresis due to its thermal inertia Effect of temperature control.
  • axially parallel channels have been drilled in the roller body, which are connected to one another and to central bores which cause the inflow and outflow through bores which start and run at an angle in their mouths.
  • the effort to be made for the bores feeding and connecting the bores has proven to be undesirably high.
  • calender rolls are built, the roll body of which is designed as a hollow cylinder which is closed on one side and is provided in one piece with a roll pin, the opening opposite the roll pin with a separate one Flange journal is completed.
  • a forced circulation for the thermal medium is created here, in that the cavity is largely filled by a displacer body usually made of sheet steel, so that an annular passage cross section of small thickness remains for the medium, the limited cross-sectional area of which ensures flow rates ensuring the heat transfer Medium results.
  • the thermal medium can be supplied and removed through the two pins from or to different sides; in the case of driven calender rolls, however, it has proven useful to keep the drive side free of supply lines of the thermal medium and to carry out both the supply and the discharge via a connection head provided on the flange side opposite the drive side.
  • the innovation is based on the task of creating a calender roll of the same type in terms of flow technology, which can be produced and maintained with reduced expenditure, which allows heating of precisely defined jacket areas, and which is robust and stable even at high speeds and strong positive and negative accelerations proves, and which can therefore be operated safely with a long service life.
  • roller body of the calender roller being connected on both sides to flange pins and the areas of the end faces of the roller body enclosed by the mouths of the channels receding against the opposite base area area of the flange pins, forming a gap that extends at least up to these mouths of the channels, and by preferably leading central inlet and outlet bores up to these columns.
  • flange spigots arranged on both sides had already been provided for design reasons, in particular if tough, tough roller spigots were required, the resilience of which could not be achieved with one-piece roller spigots due to the special type of roller casting.
  • both the forehead can be used in the areas enclosed by the channels or their mouths
  • Surface of the roller body and the base of the flange pegs each create a gap that gives access to the channels without long, cumbersome and significant machine times bores.
  • the roller body itself is practically made in one piece, even if different cast alloys are used for areas with different radii, so that a stable roller with high section modulus is created, which can also correspond to very high acceleration stresses without deformation.
  • a defined guidance of the thermal medium is achieved, which defines the channels between the gaps formed and intersperses them with flow velocities which ensure the desired heat transfer.
  • a highly resilient, central connection of the flange pin to the roller body can be achieved if the flange pin has a flange that can be connected to the roller body and engages in the recesses of the roller body within the jacket area of the roller body.
  • the facing end faces of the approaches and the. Recesses are expediently designed so that the gaps formed run flat conical.
  • the channels can be arranged within a pitch circle that is significantly less than the diameter of the roller body.
  • the channels closer below the shell of the roller body and thus within a partial circle which is slightly less than the diameter of the roller body if a group of diverging regions of the end faces of the roller body divide along the surface lines of a truncated cone Boreholes that each open into one of the channels and in that the channels are closed at both ends outside the mouths.
  • a secure closure which at the same time defines the heatable width ranges of the roller bodies, is achieved by sealing the channels, which essentially extend from their mouth to the mouth of one of the connection bores.
  • the sealing plugs are expediently provided with at least one seal inserted into a groove.
  • the introduction of the bores is simplified and facilitated if the end-side recesses of the roller bodies have profile areas which run perpendicular to these connection bores.
  • the coolant flow can be reduced or the flow rate of the medium increased by alternately adjacent channels of groups of channels at the two roller ends being closed off by the gap and connected to one another in such a way that the channels of a group flow through the columns from the same medium in succession .
  • three or five channels forming a group can be flowed through in a meandering fashion, starting from one of the gaps, until the medium emerges from the last channel of the group into the opposite gap.
  • rings, disks or projections of the approaches of the flange pins can be tensioned against the mouths of the channels or against the mouths of end faces having connecting bores leading to the channels, which are for the beginning or the end of a Group of orifices formed by the medium through which the medium flows in succession have openings and orifices to be connected to the channels or the connection bores against the gap cover, and in that the disks, rings or lugs or the end face of the roller body have mouths connecting recesses or grooves.
  • connection bores forming the beginning or the end of a group of channels through which the medium flows one behind the other can run substantially diverging along surface lines of a truncated cone, and connection bores leading to channels to be connected to one another are additionally arranged obliquely against the surface lines such that they cross each other, their mouths are closed by plugs.
  • the weight of calender rolls can be reduced if their core area is turned out and the core area is closed off at least on one side by a disk that overlaps it and can optionally also be provided with openings and recesses or grooves.
  • the flange pins can each have feed or discharge bores guided up to their base surfaces, so that the medium can be supplied on one side of the roller and discharged on the other.
  • both the roll body of the calender roll and one of the flange journals with an axial bore and the flange journal with a connection head for supplying and discharging the thermal medium, and the central bore of the flange journal to be a central one into the central bore of the roller body leading pipe to have the bore of the flange pin penetrating to form a tubular jacket-shaped space.
  • a calender roll 1 is shown, below the outer surface of its roll body 2 starting from end faces 3, a family of axially parallel channels 4 is drilled, which can each have the same distance from the roll axis.
  • flange spigots for example the flange spigot 5
  • the flanges 6 of which are clamped by means of screws 7 to the roller body 2 of the calender roller 1 such that projections 8 of the flange spigots 5 engage in centered recesses in the roller body 2.
  • the bases 9 of these approaches are worked in a slightly conical shape so that defined gaps 10 and 11 remain between them, the outer ends of which extend up to the mouths of the channels 4, while the gaps on their inner Merging ends in inflow and outflow bores 12 and 13 of the flange pins 5, which are each equipped with connection heads 14 and 15.
  • the thermal medium can thus be supplied to the connection head 14, for example, and pass through the bore 12 of the flange pin 5 in accordance with the flow arrows entered into the gap 10 formed in front of the end face 3 of the roller body 2, which distributes the medium to the sheet of channels 4.
  • the thermal medium After passing through the channels, the thermal medium is taken up by the gap 11 and again in the arrow direction, ' near the axis to the drain hole 13 and through this to the connection head 15, from where it is returned to the heating control unit via a line network.

  • displacer rolls can be constructed in such a way that, in order to improve these boundary conditions, roll ends covered by the edges of the paper web are no longer heated; in the case of calender rolls heated by means of axially parallel channels, however, the calender roll is heated along the length of its channels and thus practically along its entire length. Furthermore, it has been found that channels which are smooth in order to be able to open into gaps formed behind the projections of the flange journals are to be arranged relatively deep under the lateral surface of the calender roll. This not only causes an occasionally undesirably high thermal inertia of the roll, it also blurs the limits of heated and unheated length ranges of the rolls.

Since the mouths of the channels 32 are already overlapped and closed by the flanges 27 and 28, the mouth regions of the channels are thus removed from the actual circuit of the heating medium until the connection bores open.
  • the effective length of the channels is additionally and defined by sealing plugs 35 inserted into their mouths, which fill the mouth area of the channels up to the area where the connecting bores open and are appropriately additionally sealed.
