an entirely simple problem. Due to the fact that during cooling the casing shrinks more than the cemented carbide ring, inwardly directed forces on the cemented carbide ring are produced, giving rise to axially directed tensile stresses on the outer surface of the cemented carbide ring, which are acting perpendicularly to microcracks generated in the roll surface during rolling. Under the influence of these tensile stresses, the microcracks propagate in depth, which may cause roll breakage or need for excessive dressing amount, limiting the total rolling capacity of the roll.
A solution to this problem is described in U.S. Pat. No. 5,044,056, the disclosure of which is hereby incorporated by reference. According to that patent, one or several cemented carbide rings are cast into a casing of an ironMax and co discuss England’s first ever penalty shootout win at a World Cup, Sweden progressing, a Mrs Granqvist update, Paul Konchesky and which of our panellists dealt with tonight’s football the best

Max Rushden is joined by Barry Glendenning, Paolo Bandini and Sam Diss to look back at the final two round of 16 matches, starting with England’s first ever penalty shootout win at a World Cup. Barcelona’s Yerry Mina equalised for Colombia deep into time added on, setting up a nervy, goalless extra time, after which England prevailed from the spot.

In the other game, Sweden beat Switzerland 1-0, courtesy of a deflected Emil Forsberg goal. Low on
