  • Shear for shearing products and associated production process
    Patent number: 9221086
    Abstract: Rolling mill shear provided with at least one blade having characteristics of toughness and resistance to thermal shock typical of the family of tool steels for hot shearing and at the same time having sufficiently high characteristics of surface hardness and wear resistance, typical of tool steels for cold shearing. This shear is particularly suitable for carrying out, with greater efficiency and for a longer time, relative to the known shears, the shearing of sections or bars at a temperature between 150 and 800° C., downstream of the Quenching & Tempering heat treatment thereof.
    Type: Grant
    Filed: September 29, 2011
    Date of Patent: December 29, 2015
    Assignee: Danieli & C. Officine Meccaniche S.P.A.
