Abstract
In order to increase the endurance and lifetime of highly loaded components (6, 8, 12, 14, 24, 26, 34) of a steelworks, an electrolytically applied coating (38) is provided, having a ductile metallic base material (39), in particular nickel or a nickel alloy, with hard material particles (40), in particular boron carbide particles, incorporated in it. This measure achieves high resistance to corrosion, good thermal conductivity and at the same time high mechanical loadability.
Claims24
A component (6, 8, 12, 14, 24, 26, 34) of a steelworks, such as a continuous casting installation (4) or rolling mill (22, 32), which has a basic body (37) on which a coating (38) is applied, the coating (38) comprising a ductile metallic basic material (39) with hard material particles (40) embedded in it.
The component (6, 8, 12, 14, 24, 26, 34) as claimed in one of the preceding claims, in which the fraction of hard material particles (40) in the coating (38) is in the range of between 5% by volume and 30% by volume.
The component (6, 8, 12, 14, 24, 26, 34) as claimed in one of the preceding claims, in which the hard material particles (40) have a size in the nanometer range or in the micrometer range.
The component (6, 8, 12, 14, 24, 26, 34) as claimed in one of the preceding claims, in which the hard material particles (40) used are boron carbide particles, tungsten carbide particles and/or diamond particles.
The component (6, 8, 12, 14, 24, 26, 34) as claimed in one of the preceding claims, in which the thickness (D1) of the coating (38) is in the range of between about 0.7 mm and about 6 mm, in particular in the range of between about 2 mm and 3 mm.
The component (6, 8, 12, 14, 24, 26, 34) as claimed in one of the preceding claims, in which the coating (38) is applied electrolytically.
The component (24, 26, 34) as claimed in one of the preceding claims, in which a hard coating (42), in particular a diamond coating, is applied to the coating (38).
The component (12, 14) as claimed in one of the preceding claims, which is a segment (12), having a plurality of transport rollers (14), of a continuous casting installation (4).
A method for producing a component as claimed in one of the preceding claims, in which the coating is applied electrolytically.
