A pouring facility includes a mold conveying device configured to convey a mold, a molten-metal discharging container configured to store waste molten metal, and a pouring machine movable on a conveyance path located between the mold conveying device and the molten-metal discharging container, the pouring machine being configured to tilt a ladle in a first direction to pour molten metal into the mold conveyed by the mold conveying device, and tilt the ladle in a second direction opposite to the first direction to discharge waste molten metal into the molten-metal discharging container.

Pouring facility

A casting method includes pouring a molten metal in a ladle into a mold, analyzing at least one of a composition and a physical property of a test piece generated based on the molten metal sampled from inside the ladle, and performing appearance inspection of a casting product taken out from the mold, wherein in the performing appearance inspection, the at least one of the composition and the physical property of the test piece obtained in the analyzing is displayed on a display.

Casting method

Casting facility includes a pouring machine for pouring molten metal in a ladle into a mold molded by a molding machine and conveyed to a pouring site, and the pouring machine includes a plan acquisition unit configured to acquire a planned temperature range of the molten metal for the mold, a temperature sensor configured to detect a temperature of a pouring flow during pouring of the molten metal into the mold, and a temperature determination unit configured to determine whether or not the temperature of the pouring flow is within the planned temperature range, and the pouring machine stops the pouring of the molten metal into the mold when it is determined that the temperature of the pouring flow is not within the planned temperature range.

Casting facility

A casting facility control system includes: a database storing conveyance positions and mold information in association with each other; an update section updating the mold information associated with each conveyance position stored in the database; a measurement section measuring a weight of molten metal in a ladle transported to a pouring machine; a calculation section calculating the number of flasks by which the molten metal poured from the ladle can be held; a decision section recognizing, based on the number of flasks by which the poured molten metal can be held, a plurality of molds into which the molten metal to be next transported to the pouring machine is poured, adding up the planned weight of molten metal corresponding to each of the recognized molds, and determining a predicted weight of molten metal to be next transported to the pouring machine; and an output section outputting the predicted weight.

Casting facility control system

The pouring apparatus includes: a ladle including a nozzle and configured to store molten metal; a tilting mechanism configured to tilt the ladle so that a tapping position from the nozzle of the ladle is maintained at a constant position; and a radiation thermometer including a sensor head configured to output a signal related to a temperature at a measurement position and an amplifier configured to process the signal output by the sensor head, wherein the sensor head is disposed so that the measurement position is at the tapping position, and outputs a signal related to a temperature of molten metal in a molten metal flow at the tapping position.

Pouring apparatus

A casting plant to produce a cast product with a high quality and a method for managing data for molding the mold and data on the conditions of the molten metal in the casting plant are provided. The controller () for the molding unit issues a serial number for the mold to a mold (M). The controller () for the unit for conveying the molds shifts the serial number for the mold in accordance with a movement of the mold. It also gathers data on the mold and links the data for molding the mold with the serial number for the mold. When the molten metal is poured from the ladle into the mold, the controller () for the unit for pouring the molten metal sends to the computer () for controlling the casting plant the serial number for the ladle that is linked with the data on the conditions of the molten metal and that is linked with the serial number for the mold.

To provide a system for producing steel castings that is simple and suitable to continuously produce many small steel castings. A systemcomprises multiple furnacesthat are aligned and hold molten metal for cast steel, a pouring machinethat has a ladlethat receives the molten metal from the furnaces, wherein the pouring machine travels in parallel to a line of the furnaces and pours the molten metal into a moldby tilting the ladle, a linefor conveying the molds that intermittently conveys molds that are aligned in parallel to a direction in which the pouring machine travels, wherein the line is located on the opposite side of the furnaces across the pouring machine, and a temperature sensorthat measures a temperature of the molten metal so as to generate an alarm if the temperature is low.

System for producing steel castings

A pouring apparatus comprises a ladle configured to include a body and a nozzle, and a controller configured to control a tilt angle of the ladle, wherein the body includes a side face portion, an inner surface of the side face portion is formed in a cylindrical shape or in a conical shape, the nozzle includes a nozzle tip for guiding molten metal to the outside and is integrated with the body on a side of the body, in order to guide the molten metal in the body to the nozzle tip and to pour out the molten metal through the nozzle tip, and the controller controls the tilt angle on the basis of a surface area of the molten metal when the ladle is tilted.

Molten metal pouring device and molten metal pouring method

A pouring machine is provided to constantly maintain the level of the surface of melt without a leak, or the like, to maintain a necessary and sufficient pouring rate. The pouring machine () that pours molten metal from a container into molds in a line comprises a bogie () that travels along the molds; a mechanism () for moving the container back and forth that moves the container perpendicularly to the direction that the bogie travels; a mechanism () for tilting the container that tilts the container; a weight detector () that detects the weight of molten metal in the container; a surface-of-melt detector () that detects the level at a pouring cup () of a mold (); and a controller () that controls the angle of the tilt of the container by using the detected level and the detected weight.

Pouring machine and method

A low-pressure casting apparatus is provided wherein molten metal can be precisely cast even into a casting mold of a comparatively small capacity, not to mention a casting mold into which a large capacity of molten metal is to be cast, and wherein the casting mold is accurately pressurized. The casting mold, into which a large capacity of molten metal is to be cast, can be cast by connecting at least two crucibles to the casting mold via at least two stalks and at least two connection mechanisms, and by connecting at least two molten-metal holding furnaces to the pressurized-gas supply means via at least two connecting mechanisms, after the pressure chambers of the holding furnaces are made to communicate with each other via the communication mechanisms. A casting mold of a relatively small capacity can also be cast by connecting one of the crucibles to the mold via one of the stalks and one of the connecting mechanisms, and by connecting one of the holding furnaces to the pressurized-gas supply means via one of the connecting mechanisms.
