Abstract
A method and a device for producing ingots from metal or metal alloy. The method and the device are suitable for producing ingots from nickel, titanium, vanadium, niobium, tantalum, zirconium, hafnium, or alloys thereof and alloys of the metals in continuous casting methods. The device has an ingot chamber, which is suitable for receiving multiple cast ingots and for allowing the ingots to cool in the ingot chamber. For this purpose, the ingots are arranged in the ingot chamber in a horizontally movable manner on ingot tube section.
Claims16
A device for producing ingots from metal or metal alloy, having
- a. at least one melting device,
- b. at least one permanent mold,
- c. at least one gastight ingot chamber, which is arranged at least partially underneath the at least one permanent mold,
- d. wherein the at least one gastight ingot chamber has a plurality of ingot holding means, which are suitable for receiving at least one ingot in each case,
- e. wherein the ingot holding means are horizontally movable, with the result that
- i. an ingot holding means is moved to a melting position underneath the at least one permanent mold to receive an ingot, and
- ii. is then moved to a different location in order to free the melting position for another ingot holding means,
- f. wherein the at least one permanent mold is arranged in such a way that molten metal or metal alloy is fed to it from the at least one melting device.
A method for producing ingots from metal or metal alloy, comprising the following steps:
- a. melting a metal or a metal alloy to form a melt,
- b. casting an ingot from the melt by means of a permanent mold,
- c. lowering the ingot out of the permanent mold onto an ingot holding means in a gastight ingot chamber, while the ingot holding means is in a melting position,
- d. moving the ingot holding means horizontally, with the result that the ingot holding means occupied by the ingot frees the melting position for another, unoccupied ingot holding means,
- e. allowing the ingot to cool in the ingot holding means,
- f. moving the occupied ingot holding means to an unloading position in the ingot chamber, and
- g. unloading the ingot from the ingot chamber at the unloading position.
