The present invention provides pouring equipment of a tilting-type that can appropriately pour molten metal at a high speed corresponding to the speed of molding. It also provides a method of pouring the molten metal. The pouring equipment has a holding furnace supplying the molten metal by being tilted, a pouring ladle pouring the molten metal supplied from the holding furnace into molds that are intermittently transported, a device for measuring weight of the molten metal in the pouring ladle, and equipment for control that controls the tiltings of the holding furnace and the pouring ladle. The equipment for control has a device for storing results from measurements and devices for calculating the first and second flow rate. The equipment controls the tilting of the ladle so that the ladle pours the molten metal into the mold according to the flow pattern of the product.

Pouring equipment and method of pouring using the pouring equipment

To transfer the molten metal that is melted in the melting furnace into the pouring ladle, which is a vessel for transporting the molten metal to the place for pouring, and to further lift the pouring ladle by another crane to pour the molten metal, requires time, such that the molten metal that had a high temperature when melted by the melting furnace is likely to cool down and to cause a defective cast product. To solve the problem the pouring equipment of the present invention pours the molten metal into the mold, comprising the melting furnace that produces molten metal by melting metal material and a driving apparatus that can move the melting furnace backward and forward or in a traverse direction, wherein the pouring equipment moves the melting furnace to the predetermined position by the driving apparatus, and then pours the molten metal into a mold by tilting the melting furnace relative to the mold.

Pouring equipment having melting furnace

A cast-steel pouring apparatus including a furnace body having a furnace main body that includes a fire-retardant lining material demarcating a retainer chamber for retaining molten steel therein, and a steel-outing trough unit that protrudes from the furnace main-body toward an outside and with a trough length equal to &#x2154; or less of an inside diameter of a top-face opening in the retainer chamber; a first pivot shaft having a first axial line oriented along a lateral direction such that the furnace body can pivot on the first pivot shaft in a longitudinal direction; a first pivot driving source for causing the furnace body to pivot about the first axial line of the first pivot shaft which serves as the pivotal center in the longitudinal direction, thereby causing the molten steel to discharge from the steel-outing trough unit of the furnace body, which has pivoted with respect to a sprue of casting mold.

Cast-steel pouring apparatus

An inoculant feeding method and apparatus in which a desired amount of inoculants can be fed into molten metal poured into a mold by an automatic molten metal pouring machine, and an automatic molten metal pouring machine using the apparatus. An inoculant feeding apparatus () feeds inoculants into molten metal poured into a mold () from an automatic molten metal pouring machine (), at a predetermined proportion corresponding to the amount of the poured molten metal which gradually varies. The apparatus () is provided with a hopper () which is attached to a truck () and which stores the inoculants, a screw conveyor () attached to a lower end of the hopper, a drive mechanism () which is attached to a base end of the screw conveyor and which drives the screw driver, and a controller () which controls the drive mechanism. Due to the control by the controller (), the screw conveyor () is driven through the drive mechanism (), corresponding to the amount of the molten metal poured from the automatic molten metal pouring machine () so that the inoculants are fed from the screw conveyor () into the molten metal poured into the mold () from the automatic molten metal pouring machine ().

An automatic pouring method without using a servomotor having a vertical output shaft, establishing the pouring at a low level, eliminating the unstable pouring, sand inclusion, and gaseous defects. An automatic pouring method using a ladle to be tilted for pouring molten metal into a pouring cup of a flaskless or tight-flask mold in at least one pouring device movable along an X-axis parallel to a molding line in which the mold is transferred, wherein the ladle is moved along a Y-axis perpendicular to the molding line in a horizontal plane and is tilted about a first axis of rotation and further about a second axis of rotation.

Automatic pouring method and device

An apparatus for forming a sprue and a communication hole in a vacuum-sealed mould. This method includes steps of: laying a shield film over a pattern and a sprue forming pattern or a communication hole forming pattern; assembling the pattern with a moulding flask; charging a charged material of particulate type into the moulding flask, and laying another shield film over the moulding flask, the charged material and the top portion of the sprue forming pattern or the communication hole forming pattern; welding the two films together along the periphery of the top surface of the sprue forming pattern or the communication hole forming pattern; cutting the two films, thus welded, along the periphery of the top surface of the sprue forming pattern or communication-hole forming pattern; and removing the sprue forming pattern or the communication hole forming pattern through the cut portion of the film. In addition, there is disclosed an apparatus for welding the two films together and cutting the same along the periphery of the top surface of the sprue forming pattern or the communication hole forming pattern.
