Embodiment Construction

[0033] exist figure 1 A continuous casting roll 1 is seen in the figure, which has a roll neck 9 which is not discussed further here, and which furthermore consists of a cylindrical roll base body 2 in the exemplary embodiment. A coating 3 made of wear-resistant material is plated on the roller base 2, and its structure is in figure 2 described in detail.

[0034] The coating 3 has a coating thickness D which can be, for example, between 0.05 mm and 2.0 mm. What is important is that the surface 4 of the coating 3 is the running surface of the roll 1 which, in the case of continuous casting rolls, is in contact with the still hot strand and is therefore exposed to high-temperature mechanical and chemical corrosion loads.

[0035] The coating 3 consists of nickel or a nickel alloy, wherein the coating is applied galvanically (electrolytically) to the roller base 2 (for this see image 3 ).

[0036] In order to increase the in particular mechanical and thermal hardness of th...

Abstract

The invention relates to a roll (1) for metal production and / or metal processing, in particular a continuous casting roll, which has a roll parent body (2) of metal and a coating (3) of wear-resistant material applied to said roll parent body (2). In order to make the roll, in particular the continuous casting roll, especially wear-resistant, the invention provides for the coating (3) to have electrolytically applied nickel, wherein the surface (4) of the coating (3) forms the working surface of the roll (1). Furthermore, the invention relates to a method of producing a roll (1) for metal production and / or metal processing, in particular a continuous casting roll.

Description

technical field [0001] The invention relates to a roll, in particular a continuous casting roll, for metal production and / or metal processing, which roll has a metal roll base body and a coating made of a wear-resistant material applied to the roll base body. Furthermore, the invention relates to a method for the production of such rolls, in particular continuous casting rolls. Background technique [0002] The slab guide rollers play a huge role in the unimpeachable function of the continuous casting machine, the quality of the castings and the economy of the plant. The task of the continuous casting billet guide roller is to support, guide, bend and transport the solidified continuous casting billet after leaving the mold. At the same time, the roll bodies and the bearings of the combined rolls are subjected to high temperature, mechanical and chemical corrosive loads. [0003] The thermal load is generated by the direct contact of the roll body surface with the slab, wh...
