ABSTRACT:
Slag on the surface of a molten metal is drawn into the inlet end of a suction pipe which is provided with a water cooling jacket having orifices permitting the flow of water to the inlet end of the pipe for pelletizing the entering slag. The suction pipe is connected to a separator hopper, which is evacuated by an exhaust pump to create the suction, and which includes a slag discharge port closed by an openable valve. A sealed auxiliary hopper receives slag from the discharge port of the separator hopper when the valve thereof is opened, and also includes a slag discharge port closed by an openable valve. The hopper discharge valves are operated alternately by suitable control means so that when one valve is open the other is closed, thereby enabling slag to be continuously sucked, separated, and intermittently discharged from the auxiliary hopper.
