  • Arrangement for and a method of introducing particulate material into molten baths
    Patent number: 4042223
    Abstract: A suspension of a particulate material in a carrier medium is introduced into a molten bath through a lance which has an inlet port, an outlet port and a passage communicating the inlet port with the outlet port. The flow-through cross-sectional area of the outlet port is smaller than the flow-through cross-sectional area of the passage so that the speed of flow of the suspension through the outlet port is higher than the speed of flow of the suspension through the passage and penetration of the molten bath into the outlet port is thereby prevented. The supension is introduced into the inlet port through a conduit having a smaller flow-through cross-sectional area than the passage so that the pulsations of the solution which occur in the conduit are damped in the passage. A duct may introduce pressurized medium into the region of the outlet port to thereby loosen the particulate material accumulated in the region of the outlet port.
