Abstract
A melting furnace for melting a metallic material includes a receiving region for receiving the metallic material, a gas-burning device where the gas-burning device is disposed in the receiving region and where metallic material disposed in the receiving region is heatable and meltable by burning a gas by the gas-burning device, a heat-retention region, and an electrically operable heating device where a melt in the heat-retention region is able to be kept warm by the electrically operable heating device.

A melting furnace for melting a metallic material, comprising:
- a receiving region for receiving the metallic material;
- a gas-burning device, wherein the gas-burning device is disposed in the receiving region and wherein metallic material disposed in the receiving region is heatable and meltable by burning a gas by the gas-burning device;
- a heat-retention region;
- and
- an electrically operable heating device, wherein a melt in the heat-retention region is able to be kept warm by the electrically operable heating device.
A method for melting a metallic material by a melting furnace, comprising the steps of:
- receiving the metallic material in a solid aggregate state of the metallic material in a receiving region;
- heating, and thereby melting, the metallic material in the receiving region by a gas-burning device which is disposed in the receiving region by burning a gas;
- receiving a melt which results from the melting of the metallic material and is formed by the metallic material in a heat-retention region;
- and
- keeping the melt warm in the heat-retention region by an electrically operable heating device.
