Definitions
- the invention relates to a heatable roll having a coating providing a web contact side, which is suitable for a machine for producing and / or finishing a material web, in particular fibrous web such as. Paper, cardboard or tissue web.
- the invention also relates to a method for coating such a roller.
- Object of the present invention is to propose heated roll with a coating of the roll shell, wherein the coating has a relation to the prior art improved thermal conductivity combined with a sufficient abrasion resistance.
- the heatable roll according to the invention is characterized in that the coating comprises or is formed from at least one metallic or metal-carbide layer, wherein the at least one metallic or metal-carbide layer comprises a first layer-providing layer component and a second layer component distributed in the matrix comprises or is formed from these, and the first layer component a higher abrasion resistance than the second layer component and the second layer component has a greater thermal conductivity than the first layer component.
- Suitable means for heating the roll mantle are well known and include means in which the roll is heated with steam and / or oil and / or hot water and / or by means of radiation and / or induction.
- a metallic layer is a layer which essentially has metallic constituents or only metallic constituents.
- a metal-carbide layer is also a layer that has essentially metallic and carbide constituents or only metallic and carbide constituents.
- the second layer component in particular comprises copper or a copper-based alloy or is in particular formed therefrom.
- a copper-base alloy is meant a copper alloy that consists of more than 50% by weight of copper. Due to the ductile behavior of copper, the adhesion of the at least one layer, in particular the coating, are improved, to the lateral surface of the heated roll, whereby the heat transfer between the coating and roll shell is improved.
- the at least one layer is replaced by 60% by weight or more, preferably more than 75%, of the first layer component and by at most 40% by weight, preferably 5-25% by weight, particularly preferably 10-15% by weight , the second layer component is formed.
- the roller may be a drying cylinder, in particular a drying cylinder for a single-row or double-row cylinder drying group or a Yankee drying cylinder.
- the heated roller is a heated calender roller.
- a heatable roller which has a base body with a metallic and cylindrical Roll mantle and which can be heated by suitable means is proposed, the method comprising the following steps:
- Layer component has a greater thermal conductivity than the first layer component.
- a thermal spraying process in particular a high-speed flame spraying process (also called HVOF)
- a powder mixture comprising the starting materials for the first and second layer components may be used.
- a powder mixture can be used, which comprises a highly alloyed iron base powder and a pure copper powder, or consists of these powders.
- the at least one layer, in particular the coating can be produced by the so-called laser cladding method.
- the second layer component particularly preferably comprises a soft metal, in particular a solid lubricant, such as copper, brass, gunmetal, aluminum or lead, or a mixture of these or corresponding alloys.
- a soft metal in particular a solid lubricant, such as copper, brass, gunmetal, aluminum or lead, or a mixture of these or corresponding alloys.
- suitable materials especially non-metallic materials such as graphite, are conceivable. It may be advantageous for both the use in heated or heated rolls as well as in non-heated rolls when the soft metal has a comparatively high thermal conductivity.
