Technical Field

[0001] The utility model relates to the technical field of gold assay furnace heating, in particular to a heating device for an energy-saving gold assay furnace. Background Art

[0002] In order to determine the content of rare metal materials or materials containing rare metals, such as gold, silver, copper, lead, zinc and other concentrates, it is usually necessary to melt the materials in a gold assay furnace to enrich the rare and precious metals in the materials, then take the materials out of the gold assay furnace for cooling, and then determine the rare and precious metal content of the cooled materials.

[0003] When melting metal materials, the materials are usually placed in the furnace of the assay furnace, and then the furnace door is closed to heat the metal to melt it. However, since the traditional assay furnace and the furnace door are connected by rotation, part of the heat is dissipated through the gap between the assay furnace and the furnace door during the metal melting operation, resulting in unstable temperature in the furnace, which affects the metal melting operation.
