    摘要: The present invention relates to a process for milling a cermet or cemented carbide powder. The process comprises circulating a slurry comprising powder(s) forming hard constituents, powder(s) forming binder phase and a grinding liquid through a grinding chamber. The grinding chamber comprises grinding elements and an agitator where the agitator is rotating around an essentially horizontal axis. The process according to the present invention provides a cermet or cemented carbide powder mixture at a significantly reduced milling time.

    摘要: A method of manufacturing an as-cast composite roll by metallurgically bonding one or more rings of cemented carbide to a cast iron casing. The composite roll may be used for hot or cold rolling. The cast iron has the following composition in addition to Fe, in weight %, 1.9-2.8% Si, 0.02-0.10% Mg, 0.5-4% Ni, 0.1-1% Mn, balance Fe and a Ceqv=2.5-6.

    摘要: There is now provided a roll for hot rolling comprising 70-95 weight %, preferably 85-94 weight %, WC in a binder phase consisting of only cobalt or alternatively a Co--Ni--Cr alloy containing 20-35 weight % Ni and up to 10 weight % Cr, possibly with small additions of molybdenum. The WC grains are rounded with an average grain size between 3-10 .mu.m, preferably 4-8 .mu.m. The maximum grain size should not exceed 2 times the average grain size and no more than 2% of the grains be less than half of the average grain size.
