Description

Smelting vacuum furnace with smoke abatement mechanism Technical Field The utility model relates to the technical field of smelting vacuum furnaces, in particular to a smelting vacuum furnace with a smoke abatement mechanism. Background In the fields of metal smelting, alloy preparation and special material processing, vacuum smelting furnaces are widely used because of the capability of effectively avoiding material oxidation and improving purity. However, conventional vacuum furnaces are prone to generate large amounts of fumes and dust during high temperature smelting, especially when processing volatile (e.g., zinc, lead, or organic) materials. The smoke not only pollutes the interior of the furnace chamber, so that the observation window is fuzzy, the sensor is misjudged, but also the smoke can enter the exhaust system along with the vacuum pump, and the filter element is easy to block or pollute the environment. In addition, particles in the fumes deposit on the inner walls of the furnace or on the electrodes, reducing the thermal efficiency and even causing the risk of short circuits.
