Patent number: 10357830Abstract: The method for the production of an element subject to wear, comprising a metal matrix and at least a core of hard material. The method provides a first step in which a temporary aggregation structure is prepared with at least partly open pores, which volatilize or in any case eliminate at least partly when subjected to heating. A second step in which, on the whole internal and external surface of said temporary aggregation structure, a liquid mixture of a binder with metal powders which contain hard elements or their precursors is uniformly distributed. A third step in which the temporary aggregation structure is deteriorated by means of a thermal action of controlled heating, so as to take at least part of the temporary aggregation structure to evaporation, rendering free a volume inside the core, and to consolidate the mixture according to the conformation of the temporary aggregation structure. A fourth step in which the core is disposed in a mold so as to only partly occupy the free volume of the mold.Type: GrantFiled: July 8, 2011Date of Patent: July 23, 2019Assignee: F.A.R.—Fonderie Acciaierie Roiale—SpAInventors: Alberto Andreussi, Primo Andreussi, Enrico Veneroso, Eddy Pontelli

Publication number: 20150290706Abstract: Method for manufacturing steel casts intended to obtain a wear element, comprising at least a step of preparing at least a reinforcement insert, and a step of preparing a mold for the cast to be manufactured, the step of preparing the mold providing a sub-step of positioning the at least one reinforcement insert inside the mold in the zones corresponding to the zones of the cast coinciding with those which, in use, will be the zones of the wear element most subjected to wear, and a subsequent step of casting steel inside the mold. The step of preparing at least one reinforcement insert provides the operations of filling a substantially filiform tubular container with a mixture of powders and or small pieces and of shaping, also spatially, the filled filiform tubular container to obtain the physical structure of said reinforcement insert.Type: ApplicationFiled: July 24, 2013Publication date: October 15, 2015Inventors: Alberto Andreussi, Primo Andreussi, Eddy Pontelli, Enrico Veneroso

Publication number: 20150246391Abstract: A method for manufacturing steel casts (110), in particular but not exclusively manganese steel, intended to obtain a wear element, comprises at least a step (15) of making at least a reinforcement insert (115), a step (11) of preparing a mold (111) for the cast (110) to be manufactured, in which the reinforcement insert (115) is positioned, and a subsequent step (12) of casting the steel inside the mold. The reinforcement insert (115) is made by compacting in a desired geometric shape, by means of selective melting techniques, of an amorphous mass of hardening powder (118) obtained by mixing powders of pure elements, or of compounds that form carbides and/or micro-structures of great hardness.Type: ApplicationFiled: September 4, 2013Publication date: September 3, 2015Applicant: F.A.R. - FONDERIE ACCIAIERIE ROIALE - SPAInventors: Alberto Andreussi, Primo Andreussi, Eddy Pontelli, Enrico Veneroso

Patent number: 8636857Abstract: A method to obtain a manganese steel alloy having a percentage weight of carbon varying from about 0.5% to about 2%, a percentage weight of manganese varying from about 10% to about 20%, and a percentage weight of titanium varying from about 0.01% to about 5%. The method comprises at lest a step wherein a determinate quantity of steel scarp with manganese or steel scarp with carbon is melted in order to define a metal bath, a step wherein, in order to deoxidize the metal bath a determinate percentage weight of aluminum is added, a step wherein a determinate percentage weight of nitrogen is added, a step wherein a determinate percentage weight of titanium is added, and a step wherein the metal bath is cast at a determinate temperature.Type: GrantFiled: May 12, 2005Date of Patent: January 28, 2014Assignee: F.A.R.—Fonderie Acciaierie ROIALE SpAInventors: Alberto Andreussi, Primo Andreussi, Enrico Veneroso, Eddy Pontelli

Patent number: 8505843Abstract: A crushing mill for inert material includes a distribution unit, a crushing unit disposed below the distribution unit and a containment structure to contain the distribution unit and the crushing unit. The distribution unit receives the inert material from a feed device and suitably directs it toward the crushing unit below, for the secondary and/or tertiary crushing of the inert material. The containment structure has at least two lower lateral semi-shells, associated with the crushing unit, and at least two upper lateral semi-shells, associated with the distribution unit, which are selectively movable, independently or together, so as to obtain an at least partly open configuration of the mill, which leaves at least the distribution unit completely uncovered and easily accessible, and advantageously also the crushing unit.Type: GrantFiled: November 16, 2010Date of Patent: August 13, 2013Assignee: RAF—Ricambi Attrezzature per la Frantumazione-SpAInventors: Enrico Veneroso, Guido Andreussi, Eddy Pontelli, Olivia Andreussi

Publication number: 20110114776Abstract: A crushing mill (10) for inert material comprises a distribution unit (27), a crushing unit (32) disposed below the distribution unit (27) and a box-like structure (40) to contain the distribution unit (27) and the crushing unit (32). The distribution unit (27) receives the inert material from a feed device and suitably directs it toward the crushing unit (32) below, for the secondary and/or tertiary crushing of the inert material. The box-like structure (40) has at least two lower lateral semi-shells (35, 36), associated with the crushing unit (32), and at least two upper lateral semi-shells (17, 18), associated with the distribution unit (27), which are selectively movable, independently or together, so as to obtain an at least partly open configuration of the mill, which leaves at least the distribution unit (27) completely uncovered and easily accessible, and advantageously also the crushing unit (32).Type: ApplicationFiled: November 16, 2010Publication date: May 19, 2011Applicant: RAF-RICAMBI ATTREZZATURE PER LA FRANTUMAZIONE-SPAInventors: Enrico VENEROSO, Guido ANDREUSSI, Eddy PONTELLI, Olivia ANDREUSSI

Patent number: 7820299Abstract: Method to produce an element (10) subject to wear, such as a mechanical member, an abrasion or crushing tool or suchlike, comprising a metal matrix (14) and at least a core (12) of ceramic material. The method comprises a preliminary step wherein the core (12) is prepared by mixing at least a first component with a base of aluminum oxide in the form of a (a-Al2O3) with a second component comprising a eutectic compound with a base of a-Al2O3 and ZrO2, a second step wherein the core (12) is arranged in a mold, so as to define a free volume inside the mold, and a third step wherein a molten metal material is cast into the mold, to occupy the free volume so as to anchor to the core (12) and thus form a single body.Type: GrantFiled: May 6, 2004Date of Patent: October 26, 2010Assignee: F.A.R.- Fonderie Acciaierie Roiale-SpAInventors: Alberto Andreussi, Guido Castenetto, Valeria Moroso, legal representative, Nella Castenetto, legal representative, Silvana Castenetto, legal representative, Primo Andreussi, Eddy Pontelli
