LUCIFER FURNACES: Pot Furnaces

June 27, 2012

This company recently announced it has supplied several top-loading pot furnaces to a customer for use with glass and ceramic research. The series 2055 pot furnaces, available in 10 standard sizes, are used for salt bath heat treatment, reportedly providing high-quality surface protection, minimizing scale, oxidation, and decarburization.

Pot furnaces are constructed with multilayered insulating firebrick and mineral wool insulation for maximum heat storage and low outside skin temperature. Units include a stainless steel pot designed with a flange for sealing against the roof plate, which is constructed of heavy-gauge steel plate to withstand warping and distortion from chamber heat. 

Large models are constructed with a roller-mounted lid to reduce bath surface heat loss during idle periods; the lid track extends beyond the back of the furnace for unobstructed access into the chamber. Heavy-gauge, coil-wound, low-watt-density heating elements in easily removable radiant panels located on all four side walls of the heating chamber are divided into several zones to provide uniform heat to 1500°F. Separate thermocouples monitor both chamber and pot medium temperatures. Side-mounted power regulating equipment includes a magnetic contactor and 230 or 460 volt-to-110 volt control transformer, as well as terminal blocks, instrument fuses and power connection terminals.
