Abstract
The invention provides an electromagnetic upward suspension continuous casting device which comprises a graphite pipe (1), and the graphite pipe (1) is provided with a protective heat insulation sleeve (12), an electromagnetic pump (5), a crystallizer (11), an auxiliary cooler (16) and an upper traction device (17) which are sheathed outside the graphite pipe (1) and sequentially arranged from bottom to top along the vertical direction. The electromagnetic upward suspension continuous casting device can lead solution to produce upward thrust and simultaneously overcome gravity by leading an upward movement electromagnetic field produced by the electromagnetic pump to be acted on metal solution in the graphite pipe, thereby reducing the hydraulic pressure of molten metal to minimum and further avoiding a plurality of problems produced between a casting mold and a metal interface. The liquid metal is continuously supplemented into the bottom part of a suspension ring and a crystallization area of the crystallizer, a metal casting blank after the crystallization is continuously cooled through the crystallizer, fully cooled through the auxiliary cooler and then pressed and pulled out by a pressure wheel of the upper traction device at the top part, and the blank drawing at the uniform speed is carried out by regulating the traction speed and the electromagnetic thrust.
