MIXING AND KNEADING MACHINE FOR CONTINUOUS CONDITIONING PROCESSES AND METHOD FOR CONDITIONING METALS

摘要

What is proposed is a mixing and kneading machine (1) which is suitable, in particular, for continuously conditioning metals such as aluminium or magnesium for a subsequent die-casting operation. To this end, the mixing and kneading machine (1) has a worm shaft (3) which rotates and at the same time moves in translation in the axial direction in a housing (2). The temperature of both the housing (2) and the worm shaft (3) is controlled by means of a flowing gas in such a manner that the conditioned metal assumes a thixotropic state when it leaves the mixing and kneading machine (1).
