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.

1. Method for manufacturing steel casts, in particular but not exclusively manganese steel, intended to obtain a wear element, comprising at least a step of making at least a reinforcement insert, a step of preparing a mold for the cast to be manufactured, in which the reinforcement insert is positioned, and a subsequent step of casting the steel inside said mold, wherein said at least one reinforcement insert is made by compacting in a desired geometric shape, by means of sintering techniques with a selective and localized melting of the EBM (Electron Beam Melting) type, or SLM (Selective Laser Melting), or other similar or comparable techniques, an amorphous mass of hardening powder obtained by mixing powders of pure elements, or of compounds that form carbides and/or micro-structures of great hardness which due to the effect of the melting generate carbides and/or micro-structures of great hardness.
