  • Patent number: 9410230
    Abstract: A wear-resistant material comprising an alloy that contains: 1.5-5.5 wt. % carbon, 0.1-2.0 wt. % silicon, max. 2.0 wt. % manganese, 3.5-30.0 wt. % chromium, 0.3-10 wt. % molybdenum, 0-10 wt. % tungsten, 0.1-30 wt. % vanadium, 0-12 wt. % niobium, 0.1-12 wt. % titanium and 1.3-3.5 wt. % nickel, the remainder being comprised of iron and production-related impurities, whereby the carbon content fulfills the following condition: CAlloy[w %]=S1+S2+S3 where S1=(Nb+2(Ti+V?0.9))/a, S2=(Mo+W/2+Cr?b)/5, S3=c+(TH?900)·0.0025, where 7<a<9, 6<b<8, 0.3<c<0.5 and 900° C.<TH<1,220° C.

  • Publication number: 20130284840
    Abstract: A roller press, in particular for processing highly abrasive materials, includes at least two press rollers, each of which is provided with a wear protection layer arranged on a base body. The wear protection layer includes plate-shaped and pin-shaped wear resistant material elements. The plate-shaped, wear resistant material elements are applied to surfaces of two opposed edge areas of each base body by sintering with or without pressure, preferably by a hot isostatic pressing operation. The pin-shaped wear resistant material elements are arranged in a central section of each base body extending between the edge areas. A method of producing a wear protection layer, in particular for a press roller, is also provided.
