As shown in FIG. 3, flow inducement or stirring apparatus 500 includes electromagnetic induction apparatus in the form of a generally rectangular box 501 connected to an inclined end wall 502 of a cradle or port 503 of the apparatus 500, being generally of right-angled isosceles triangle cross-section. The inclined wall 502 is angled at 45° to the vertical wall 504 and horizontal wall 505 of the cradle or support 503. The manner in which the cradle or port 503 can be connected into the vertical end wall 600 of the furnace 601 should be evident from FIG. 3 of the drawings. The port or cradle 503 can be fixed into the wall 600 of the furnace 601 by creating an aperture 602 of an appropriate size and by utilising usual refractory techniques to fix the port in the aperture The electromagnetic induction apparatus 501 is connected to said end wall 502 by any appropriate means and, in use, acts to create circulation of molten metal in the furnace in a vertical plane. |
