Process for the preparation of thin-wall casting technique chill casting with crystallization under pressure

摘要

1. A method of producing a thin-wall castings by casting in a metal mold with the crystallization under pressure, which comprises casting a melt into the mold through the gating-nutritional system, characterized in that the initial filling of the mold the melt is effected by its flow by gravity, and then degassing is carried out metal air through the riser to evenly fill the mold cavities followed by crystallization of the casting under pressure to compensate for shrinkage splava.2. A method of producing a thin-wall castings by casting in a metal mold with crystallization under pressure according to claim 1, characterized in that the crystallization is carried out under a casting pressure of 0.1-0.4 MPa.
