Title:
アルミニウムを回転子上に鋳造する方法
Document Type and Number:
Japanese Patent JP7110477
Kind Code:
B2
Abstract:
A method for casting aluminum on a rotor, comprising: installing casting equipment on a casting workbench and storing enough molten aluminum in the casting equipment, wherein the casting equipment comprises an heat preserving furnace and an electromagnetic pump arranged at a side of the heat preserving furnace ; assembling a plurality of rotor iron cores with a plurality of dies respectively and preheating outside the casting workbench; installing the plurality of preheated dies on a plurality of liquid outlet gates at a top end of the electromagnetic pump, wherein each liquid outlet gate is matched with a liquid inlet gate of the dies; heating and keeping the installed die in a multi-stage heating mode; controlling the pressurizing pressure of the electromagnetic pump in time-period when the electromagnetic pump is used for casting; and after completing casting, moving the plurality of dies out of the casting workbench to be cooled. According to the method for casting aluminum through the rotor, the casting efficiency is improved by reasonably distributing the heating time and the one-time multi-casting mode; the top-down temperature gradient is matched with accurate pressure control, so that the compensation capacity is improved.
