<p>Electric vacuum furnace plant comprises three chambers. The main chamber is for the high temp. treatment of the product. To it may be connected either a pre-heating or a cooling chamber. These two chambers are attached to a central revolving column which places them below the main furnace shell and which also incorporates a mechanism for raising the chamber against the bottom inlet of the main chamber. The arrangement permits high output, good operating efficiency and good energy economy. The plant is intended for the production of high temp. components such as sintered Al2O3 components.</p> |
