Patent number: 10005113Abstract: A rolling stand for tubes or rounds comprising two or more rolls defining a rolling section of the rolling stand that is coaxial to a rolling axis Y of the same stand, each roll having a respective rolling surface defining a respective straight line of symmetry passing through the rolling axis and through the center of symmetry of the respective surface, thus determining a first half and a second half of the respective surface. The rolling stand also including two gap zones having a radial distance from the rolling axis and a groove bottom zone having a radial distance from the rolling axis at the intersecting point of the respective surface with the respective straight line of symmetry, the rolling stand providing, for each roll on said respective rolling surface, at least one first pushing zone and at least one second pushing zone.Type: GrantFiled: September 28, 2012Date of Patent: June 26, 2018Assignee: Danieli & C. Officine Meccaniche S.p.A.Inventors: Ettore Cernuschi, Fabio Lacapruccia, Gianluca Bazzaro

Patent number: 8899304Abstract: Crystallizer for continuous casting, having a monolithic tubular structure defined by lateral walls (12) in the thickness of which channels (11) are made in which a cooling liquid flows, wherein two adjacent lateral walls (12) define a corner or s edge zone. On at least one longitudinal portion (C) of at least one of the lateral walls (12) and/or of at least one of the corner zones, defining a zone in correspondence with which, during use, the meniscus of the liquid metal is located, a reduction in thickness (13) is made, starting from the external surface, determining a cross section with a reduced area with respect to the remaining longitudinal portions of the monolithic tubular structure.Type: GrantFiled: November 24, 2011Date of Patent: December 2, 2014Assignee: Danieli & C. Officine Meccaniche SpAInventors: Marco Ansoldi, Gianluca Bazzaro, Andrea De Luca

Patent number: 8899305Abstract: Crystallizer for continuous casting, having a monolithic structure defined by lateral walls in the thickness of which channels (11) are made in which a cooling liquid flows. The channels (11) are geometrically sized so as to define, in a zone substantially astride the meniscus (M), an increased transit speed of the cooling liquid, wherein by increased speed it is intended that in at least some of the cooling channels (11) the speed of transit of the cooling liquid is greater in the zone astride the meniscus (M) compared with a zone below or above said zone astride the meniscus (M).Type: GrantFiled: November 24, 2011Date of Patent: December 2, 2014Assignee: Danieli & C.
