摘要： A device for submerging scrap metal includes: (a) a drive source, (b) a drive shaft having a first end and a second end, the first end being connected to the drive source, and (d) an impeller connected to the second end of the drive shaft, the impeller preferably having two or more outwardly-extending blades. Preferably, each of the blades has a portion that directs molten metal at least partially downward. The impeller design leads to lower operating speeds, lower vibration, longer component life and less maintenance. Additionally, the impeller preferably has a connective portion. The connective portion is used to connect the impeller to the shaft and preferably comprises a nonthreaded, tapered bore extending through the impeller.

摘要： A coupling mechanism for a molten metal processing system includes an elongated shaft having an upper axial end and a lower axial end. A passage having a torque facilitating shape extends through at least a portion of the shaft. The upper end of the shaft tapers inwardly and forms a tapered seat. At least one channel is machined into an outer surface of the upper end of the shaft. The channel has a first portion extending longitudinally downward from a top surface of the shaft and a second portion extending from the first portion at an angle greater than 90° relative to the first portion. A coupling member, for coupling the shaft to a drive system, includes a body having an annular wall which defines a cavity. At least one locking member is disposed on an inner surface of the annular wall which is adapted to cooperate with the channel in the shaft. The locking member is aligned with the first portion of the channel and the shaft is slid into the cavity. When the locking member reaches a bottom surface of the first portion of the channel, the shaft is turned less than one third of a rotation so that the locking member travels partially across the second portion of the channel thereby pulling the shaft upward. The cavity of the coupling member tapers outwardly forming a mouth which engages the tapered seat of the shaft in a sealing relationship.

摘要： A device for dispersing gas into molten metal includes an impeller and a shaft having a first end and a second end. The second end of the shaft is connected to the impeller and the first end is connected to the drive source that rotates the shaft and impeller. The impeller includes a bottom surface, one or more cavities open to the bottom surface, one or more gas-release openings and a connector. The shaft has a gas-transfer passage therein. A gas source is connected to the first end of the shaft. Gas is transferred through the gas-transfer passage and exits through the gas-release opening(s). At least some of the gas enters the cavities where it is mixed with the molten metal being displaced by the impeller. The configuration of the impeller causes the gas and metal to mix efficiently throughout the molten metal bath. Also disclosed are dual-flow and tri-flow impellers that can be used to practice the invention.

摘要： A technique for producing compacted graphite iron utilizes agglomerations, such as briquettes or tablets that include a sulfur-containing material such as iron sulfide. The agglomerations are free of chemical binders and utilize iron and aluminum metal powders and pressure for compaction on either roll presses or tablet machines. Addition of metal powders provides rapid dissolution of the alloy and improved heat transfer. Iron sulfide agglomerations also provide consistent and improved sulfur recoveries compared to granulated iron sulfide additions with little to no sulfur odor.
