A method for casting a melt uses a melt container in which a melt receiving space is formed. The melt container has a spout in the form of a lance on the bottom on the melt container. The method includes the following steps: filling the melt container with melt, wherein the melt is introduced into the melt receiving space of the melt container from a crucible using a spout orifice of the lance; casting at least one cast workpiece with melt; filling the melt container with melt again. When filling the melt container with melt, more melt is received in the melt receiving space than is needed for casting the cast workpiece. Directly before the renewed filling of the melt container, a remainder of melt having an oxide skin formed at the melt surface is present in the melt receiving space of the melt container.

A smart molten metal pump system and method automatically controls the operating speed of the pump rather than requiring an operator to control the speed. The system includes a pump, a controller for controlling the speed of the pump and one or more vibration sensors (such as an accelerometer) to measure vibration. The controller receives input about the vibration of the pump or one or more pump components, and possibly other data, such as the temperature of the molten metal, and/or the depth of the molten metal, ad/or parameters related to the operation of the pump. The controller analyzes the one or more inputs to vary the speed of the pump, turn the pump off, and/or send a communication to an operator.

A system according to aspects of the invention includes a pump and a refractory casing that houses the pump or is in fluid communication with the pump. As the pump operates it moves molten metal upward through an uptake section of the casing until it reaches a rectangular outlet wherein it exits the vessel. The rectangular outlet is configured to be connected to, or may be attached to, a launder. Another system uses a wall to divide a cavity of the chamber into two portions. The wall has an opening and a pump pumps molten metal from a first portion into a second portion until the level in the second portion reaches an outlet and exits the vessel.

The cast steel alloy has unexpected and unconventional results such as reduced ferrite and enhanced strengths.

A method for producing a metal ingot by using an electron-beam melting furnace having an electron gun and a hearth that accumulates a molten metal of a metal raw material, wherein the metal raw material is supplied to the position on a supply line disposed along a second side wall of the hearth that accumulates the molten metal of the metal raw material. A first electron beam is radiated along a first irradiation line that is disposed along the supply line and is closer to a central part of the hearth relative to the supply line on the surface of the molten metal, wherein a surface temperature (T2) of the molten metal at the first irradiation line is made higher than an average surface temperature (T0) of the entire surface of the molten metal in the hearth.

The present invention is related to a method for centering a pouring tube in a pouring tube assembly using a multi-piece centering sleeve by inserting a pouring tube into a holding casting aperture in a holding casting; pouring grout to fill a portion of a gap between the pouring tube and the holding casting; slipping the centering sleeve over the outside of the pouring tube until it is press fit in a portion of the gap between the pouring tube and the holding casting; adjusting the centering sleeve to center-position the pouring tube; grouting the remainder of the gap to fill all voids in the gap; installing a parting ring on top of the holding casting; and installing a holding ring around the holding casting and parting ring.
