A pump having a motor, a pump base with a pump chamber, a tangential discharge and an outlet in the pump base. A riser tube extends upward from the outlet and terminates at or above a launder in order to move molten metal out of a vessel with relatively little turbulence.

Disclosed is a transfer pump having a pump base with a pump chamber, tangential discharge and an outlet in the top surface of the pump base. A riser tube extends from the outlet and terminates at a launder in order to move molten metal out of a vessel with relatively little turbulence.

A casting area moving type dust removing device for a continuous casting machine belongs to the technical field of steel-making continuous casting. The casting area moving type dust removing device for the continuous casting machine comprises a dust collecting cover, moving rails, and a workshop dust removing system. The moving rails comprise high rails and low rails which are arranged in parallel. The dust collecting cover consists of two independent cover bodies including a main dust collecting cover and an auxiliary dust collecting cover that are arranged on bilateral sides of a casting site steel ladle rotary table. Each cover body is independently supported on the low rails and the high rails by its own wheels, and the cover body can move linearly along the rails. Adjacent sides of the two cover bodies are open without a sealing wall. A flow guidance cone and a dust removing pipeline moving along with it are arranged on the top of the main dust collecting cover. The main dust collecting cover and the auxiliary dust collecting cover move to the casting site upon casting; the cover bodies cover above the entire casting area, thereby forming a relatively complete dust removing space. The dust removing pipeline belonging to the main dust removing cover is communicated with the workshop dust removing system. The workshop dust removing system finishes the fume purification and discharges the purified fume. The casting area moving type dust removing device for the continuous casting machine has the advantages that the dust removing space covers the steel ladle and the intermediate ladle, thereby the quickly ascending fume and dust can be collected as much as possible; and accordingly the dust removing effect is good; the equipment layout is reasonable; the structure is simple; and the operation is convenient.

This invention relates to an apparatus (high shear device) and method for treating liquid metals by intensive melt shearing. The apparatus comprises a stator and a rotor with a small gap between them to provide intensive melt shearing for dispersing efficiently and distributing uniformly gas, liquid and solid phases in liquid metals without severe turbulence at the melt surface. The device can be extended to a multistage high shear pump by arranging individual rotor / stator assemblies either concentrically (one in another) or vertically. The device and high shear pump can be readily integrated into existing casting processes. The device is suitable for use in casting processes including high pressure die casting, low pressure die casting, gravity die casting, sand casting, investment casting, direct chill casting, twin roll casting, and any other casting process which requires liquid metal as a feedstock. In addition, the device is particularly suitable for providing conditioned liquid metal for both shape casting and continuous (or semi-continuous) casting of metallic materials, preparing high quality semi-solid slurries, solidification processing of particulate reinforced metal matrix composites, mixing immiscible metallic liquids and degassing of liquid metals prior to any casting processes.

There is provided an energy-saving agitator that suppresses the amount of generated heat, is easy to use and carry out maintenance, has flexibility in an installation position, and can also adjust an agitating ability. The agitator includes a furnace body that includes a molten metal room storing a molten metal, and an agitating unit that agitates the molten metal stored in the furnace body. The agitating unit includes a molten-metal driving room-forming part that is disposed in the molten metal room, applies a driving force to the molten metal, and forms a driving room of which both ends are opened; a pair of electrodes that is disposed in the driving room and makes current flow in the driving room under the presence of the molten metal; and a magnetic field unit which is formed of a permanent magnet disposed outside the furnace body, of which one pole of an N pole and an S pole faces the furnace body so that magnetic lines of force generated from the one pole cross the current, and which generates an electromagnetic force for driving the molten metal from one end toward the other end in the driving room.

To provide an exhaustion valve assembly in a die-casting mold manufactured relatively inexpensively even while having abrasion resistance. The valve assembly 1 includes a valve housing 2 divided into two parts. Exhaust ducts 3 and 5 closable by an exhaust valve 7 are provided in the front housing part 2a, an actuator 14 for operating the valve piston 8 of the exhaust valve 7 is housed in the housing 2, and the actuator 14 includes a force converter 15 operated by a casting material, and a force transmission member 20 for transmitting the closing motion of the force converter 15 to the valve piston 8 of the exhaust valve 7, and further includes a laminate spring assembly 23 for returning the actuator 14 and / or discharging a riser.

The present invention is a casting machine for casting parts in a mold out of a metal using a metal feed stock. The machine includes a processing cylinder formed in a thermally conductive block, said processing cylinder having a processing chamber and opposite first and second ends, the first end of the processing cylinder being configured to receive the metal feed stock. The machine further includes an injector cylinder formed in the thermally conductive block adjacent the processing cylinder, the injector cylinder having a shooting pot coupled to the second end of the processing cylinder by a passage configured to permit feed stock to pass from the processing cylinder into the shooting pot, a nozzle coupled to the injector cylinder configured to couple to the mold. The device includes a processing drive for driving the feed stock from the first end of the processing cylinder through the passage into the shooting pot and a heater thermally coupled to the processing cylinder. The heater and processing cylinder are configured to heat the feed stock such that the feed stock becomes progressively more liquid as it passes from the first to the second end of the processing cylinder. The machine further includes an injector plunger coupled to an injector actuator for driving the plunger sufficiently to force the metal from the shooting pot through the nozzle and into the mold.
