Definitions

  • the invention relates to a method for producing a hollow cylindrical Casting roll made of copper or a copper alloy and on the other hand a casting roll.
  • the invention is based on the object Process for producing a hollow cylindrical casting roll made of copper or a To create copper alloy, in particular the provision of large format Casting rolls made possible in a simple and economical manner. Furthermore, an economic Casting roll to be produced.
  • At least two hollow cylinders are initially reduced Mass poured. It is important here that the inside diameter of a 1st Hollow cylinder dimension larger than the outer diameter of the other 2nd hollow cylinder becomes. The difference in diameter is such that subsequently the two Hollow cylinders concentrically into one another to form a large-format casting roll can be added.
  • the advantage of such a method is that the hollow cylinders are less critically cast with a smaller mass and also by warm and / or Cold intermediate forming can be processed further if the dimensions or the mass is smaller. In this way, the requirements of the Size / mass of the inner hollow cylinder and the outer hollow cylinder significantly reduced become. This comes from both cheaper manufacturing Foundry as well as in the subsequent hot / cold intermediate forming opposite. This makes it possible, in principle, twice as much to manufacture heavy casting rolls as before.
  • the hollow cylinder can Cast blocks with subsequent intermediate forming or from pipe strings are manufactured.
  • Another advantage of the invention is that now different materials for the outer hollow cylinder and the inner hollow cylinder can.
  • a particularly fatigue-proof material for the outside To use hollow cylinders is a relatively highly heat conductive material usable.
  • the wall thicknesses according to claim 2 of the inner hollow cylinder and the outer hollow cylinder depending on the material or can be specifically adjusted depending on the application.
  • a higher degree of cold forming may also be required the hollow cylinder can be adjusted.
  • an inner hollow cylinder can also be used with a larger wall thickness compared to the wall thickness of an outer one Combine hollow cylinders.
  • the possibility of the so manufactured Large-format castor roll can also be installed on a steel core.
  • the joining the casting roll on a steel core is done in particular by hot isostatic Pressing ("bouncing").
  • the features of claim 4 allow hollow cylinders inserted into one another to be joined coaxially to one another with further hollow cylinders inserted into one another.
  • This Joining is advantageously carried out in beam welding (electron beam or laser beam welding) or by friction stir welding. This welding process allow precipitation-hardened materials to be joined properly.
  • the hollow cylinders of small mass that have been joined to form a large-format casting roll can be provided with a wear or top coating.
  • a large-format casting roll that consists of at least two hollow cylinders of low mass exists, which are concentrically joined together, forms part of the claim 5th
  • the casting roller 1 in FIG. 1 denotes a large-format casting roll.
  • the casting roller 1 sets consist of two concentrically interlocking hollow cylinders 2, 3 of lesser mass composed of copper alloys.
  • the inner diameter ID is the outer one Hollow cylinder 2 larger than the outer diameter AD of the inner hollow cylinder 3 sized.
  • the hollow cylinder 2, 3 can be made from cast blocks with subsequent Intermediate forming or be made from cast tubing.
  • the hollow cylinder 2, 3 are joined together by hot isostatic pressing.
  • Figure 2 shows a large-format casting roller 1 a, in which a total of four hollow cylinders 2, 3 are joined together coaxially.
  • the joining is by beam welding or by friction stir welding.
  • the joining takes place via the mutually facing end faces 4, 5 of the hollow cylinder 2, 3.
  • the joint is designated 6.
  • a circumferential wear or top coating 7 is also conceivable.
  • this coating 7 in dash-dotted lines.
  • the casting roller 1 a with a sleeve 8 that meets the respective requirements be provided.
  • a sleeve illustrated in broken lines 8 can in particular by hot isostatic pressing be added with the casting roller 1 a.
  • the casting roller 1 a applied to a steel core 9 can be. This is also preferably done by hot isostatic Press.
