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.

To provide a system for producing steel castings that is simple and suitable to continuously produce many small steel castings. A system 1 comprises multiple furnaces 10 that are aligned and hold molten metal for cast steel, a pouring machine 20 that has a ladle 30 that 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 mold 70 by tilting the ladle, a line 60 for 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 sensor 38 that measures a temperature of the molten metal so as to generate an alarm if the temperature is low.

A method for calculating a conveyance velocity at which oscillation of a liquid surface is suppressed in conveying a container in which a liquid is accommodated, e.g., a ladle in which molten metal is accommodated. In a graph of conveyance velocity versus conveyance time, an upwardly convex parabola and a downwardly convex parabola having vertical symmetry are prepared in advance, the downwardly convex parabola and the upwardly convex parabola are smoothly connected to form an acceleration curve, the upwardly convex parabola and the downwardly convex parabola are smoothly connected to form a deceleration curve, and the conveyance velocity is obtained from the acceleration curve and the deceleration curve smoothly connected where the slope thereof is zero.

The invention relates to a casting device for tilting-pour gravity casting, which includes a static frame, a rotatable frame adapted to be rotated with respect to said static frame over a horizontal axis. Said rotatable frame is adapted to hold a mold having a mold cavity and at least one inlet through which molten metal can flow into said mold cavity. A pouring container to contain molten metal having at least one pouring outlet through which said molten metal can flow by gravity from said pouring container to said mold inlet, and a holding arm attached to said second rotatable frame adapted to hold said pouring container so that the pouring container outlet is positioned in correspondence with said mold inlet with a pressing force over the mold as to avoid spills of molten metal out of said pouring container through the contact area of said pouring container and said mold. To enable a quick change of differently shaped casting molds with little effort, according to the invention the holding arm of such casting device includes an adjusting mechanism device for adjusting the position of the pouring container with respect to the position of said mold inlet in the direction of three space axes X, Y and Z with respect to said mold inlet.
