A method for the tilt casting of a component from light metal, in particular of an aluminum alloy, uses a tilt casting mold having a mold cavity. The melt is continuously poured directly into the casting run of the tilt casting mold, which forms the sprue of the component, at the beginning of and during the tilting movement of the tilt casting mold, using a casting ladle or a casting scoop, and flows through the casting run into the mold cavity of the tilt casting mold from the beginning, wherein the casting ladle or the casting scoop continuously tracks the casting mold during the tilting movement.

[Problem to Be Solved] A pouring control method for controlling an automatic pouring device with a tilting-type ladle is provided. By the method, a lip of a pouring ladle approaches a sprue of a mold without striking any object located within the range of its movement. Also, by the method, the molten metal that runs out of the ladle can accurately fill the mold. [Solution] The pouring control method comprises the steps of setting a target flow rate of molten metal to be poured, generating a voltage to input it to a motor that tilts the ladle (hereafter, the tilting motor) so as to reach the target flow rate of the molten metal based on an inverse model of a mathematical model of molten metal that runs out of a pouring ladle and an inverse model of the tilting motor, estimating the flow rate of the molten metal that runs out of the ladle, estimating the falling position and getting the estimated falling position to be a target position, and generating a trajectory for the movement of the pouring ladle wherein the trajectory causes the height of the lip of the pouring ladle above the level of a sprite of a mold to decrease.

Raw material feed into an electric arc furnace (EAF) is melted into heated liquid metal at a controlled temperature with impurities and inclusions removed as a separate liquid slag layer. The heated liquid metal is removed from the EAF into a passively heatable ladle wherein it is moved into a refining station where they are placed into a inductively heated refining holding vessel and wherein vacuum oxygen decarburization is applied to remove carbon, hydrogen, oxygen, nitrogen and other undesirable impurities from the liquid metal. The ladle and liquid metal is then transferred to a refining station/gas atomizer having a controlled vacuum and inert atmosphere wherein the liquid metal is poured from an inductively heated atomizing holder vessel into a heated tundish at a controlled rate wherein high pressure inert gas is applied through a nozzle to create a spray of metal droplets forming spherical shapes as the droplets that cool and fall into a bottom formed in the chamber. Spherical powder comprising the droplets are removed from the chamber through screen and blenders and then classified by size.

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 (1) that pours molten metal from a container into molds in a line comprises a bogie (10) that travels along the molds; a mechanism (20) for moving the container back and forth that moves the container perpendicularly to the direction that the bogie travels; a mechanism (40) for tilting the container that tilts the container; a weight detector (50) that detects the weight of molten metal in the container; a surface-of-melt detector (60) that detects the level at a pouring cup (110) of a mold (100); and a controller (70) that controls the angle of the tilt of the container by using the detected level and the detected weight.
