APPARATUS FOR SPRAY CASTING OF RECTANGULAR ALLOY BILLETS

摘要

A square alloy billet spray casting apparatus is provided which can easily produce a long square billet molded body having a uniform diameter.;The present invention the gas atomizer inclined the angle of the spray axis with respect to the vertical axis in the lower portion of the tundish for containing the molten alloy; A substrate positioned in the chamber such that an upper surface thereof is perpendicular to the vertical axis at a predetermined position in a path through which the spray axis of the gas atomizer passes; Substrate rotating means for rotating the substrate by rotating the angular velocity periodically with respect to the vertical axis; Substrate lowering means for continuously lowering the substrate at a growth rate of the billet along the vertical axis; And a gas atomizer vibration means for vibrating the gas atomizer with a constant amplitude in the vertical axis direction when the substrate is rotated.;According to the present invention, an effect of easily manufacturing a rectangular billet is obtained by appropriately controlling the up and down oscillation motion of the gas atomizer and the rotational motion of the substrate.;Billet forming body, billet spray casting machine, tundish, gas atomizer, gas atomizer vibrating means
