摘要： A defective engine block recycling method in a continuous casting line includes inserting a bore pin into an engine block mold, fitting a real liner to an outer circumferential surface of the bore pin, and injecting molten aluminum into the engine block mold to cast an engine block body. If an abnormality is generated in the engine block mold or the molten aluminum and if a defect is expected to generate in the engine block body, a defective engine block unit is produced by fitting a dummy liner, which is made of a material identical with or similar to a material of the engine block body, to the bore pin. The defective engine block unit thus produced is directly melted and recycled.

摘要： A coupling has an opening and a protrusion extending downward from the opening. The protrusion has threads that are preferably positioned outside of the opening. A rotor shaft that connects to the coupling has an internal bore with threads that receives and retains the protrusion, such as by a threaded connection between the two, so the protrusion applies driving force to the shaft.

摘要： An exemplary furnace system for melting stock metal includes a main hearth and a side well subsystem, which includes a melting well disposed downstream of the main hearth for receiving flow from the main hearth, an input flow inducer disposed upstream of the melting well and downstream of the main hearth, and an output flow inducer disposed downstream of the melting well and upstream of the main hearth. The input flow inducer drives molten metal into the melting well, thereby forming a differential metal head in the melting well. The output flow inducer evacuates molten metal from an output conduit, thereby reducing counter-pressure at an output port of the melting well communicating with the output conduit. This allows atmospheric pressure to add to the differential metal head in the melting well, resulting in an increase in productivity of the side well subsystem and of the furnace system as a whole.

摘要： The invention relates to a method for operating a furnace, wherein a starting material comprising at least one metal element is molten, wherein the starting material is heated by at least one burner that is operated with a fuel volume flow of a fuel and an oxidant volume flow of an oxidant. An exhaust gas temperature of the furnace is monitored in an exhaust gas line at least at one measuring point downstream of a post combustion zone, wherein in a standard operational state a target fuel volume stream and a target oxidant volume stream is fed to the burner, wherein a change of the exhaust gas temperature is recorded at predetermined time frequencies and is compared to a predetermined threshold value. The invention is characterized in that when the change of the exhaust gas temperature per time unit is greater than the threshold value, the burner is put into a reduced operational state for a predetermined time, wherein the quotient of fuel volume stream to oxidant volume stream is lowered by at least one of the following actions: A) a predetermined sudden reduction of the fuel volume stream to a reduced volume stream and B) a predetermined sudden increase of the oxidant volume stream to an increased volume stream, said quotient being reset to the standard operating state after the reduction period.

摘要： A metal melting apparatus has a heating furnace, a melting furnace mounted on the heating furnace, a high-cycle regenerative system (HRS), a raw material feeding device and a melted material feeding device mounted on the melting furnace. The HRS heats and recycles high temperature air in the heating furnace and guides the high temperature air to the preheating screw to preheat metal materials in the preheating screw. Thus, a time for melting the metal materials from solid to liquid is greatly shortened. Furthermore, a series of processes for preheating the metal materials in the raw material feeding device, melting the metal materials in the melting furnace and injecting the molten materials to the molds is fluent, time-saving and safe, and can progress continuously.

摘要： A simple, compact burner achieves a more optimal melting of a solid charge followed by performance of combustion under distributed combustion conditions. The burner achieves this by fluidically bending the flame towards the solid charge during a melting phase with an actuating jet of oxidant, redirecting the flame in a direction away from the charge, and staging injection of oxidant among primary and secondary portions during a distributed combustion phase.
