Abstract

212,494. Pratt, W. L., (Rankin, C. H.). Oct. 1, 1923. Delivering molten metal.-A forehearth forming part of a flow-feeder has its floor carried downwards to form a well 4 at the part adjacent to the tank 1, and a wall 5 for intercepting dross is arranged with its lower edge below the level of the highest part of the floor of the forehearth. The stream of metal through the forehearth is thus taken from below the surface layers of the metal in the tank. The discharge opening 9 is situated at the front end of the forehearth below a space 19, which is elliptical in plan, and the metal flows into the space through gutters between the sides of the forehearth and a block 7. Adjustable gates 11 situated in each of the gutters enable the flow of metal to be regulated. A plug 10 in the space 19 can be raised or lowered to open or close the opening 9. The forehearth 1 is built up of refractory material 12 enclosed in a metal casing 13 from which it is separated by a layer 14 of heat-insulating material. An aperture 8 formed in the wall 5 allows hot gases from the tank to circulate in the forehearth. The opening 9 may also be arranged in the wall of the forehearth instead of the floor.
