发明名称 METHOD FOR MANUFACTURING STEEL CASTS
摘要 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.
