Verfahren und Vorrichtung zum Giessen einer Aluminium-Gleitlagerlegierung

摘要

In a continuous casting of a molten aluminum bearing alloy, a casting space (C) is defined between substantially parallel opposed portions of a pair of traveling endless belts (8, 9) and the molten aluminum bearing alloy is supplied into the casting space (C) to be continuously cast into the shape of a plate. A cooling rate DELTA T during solidification of the aluminum bearing alloy is controlled so that the cooling rate DELTA T ranges between 3 and 6 DEG C/sec. where DELTA T=(T-500)/t, T is a temperature when the casting of the aluminum bearing alloy starts, and t is a cooling time in sec. between start of casting and the time when the temperature of the aluminum bearing alloy decreases to 500 DEG C.
