L&L Special Furnace Co., Inc. has received an order for 10 model GS1714 general-purpose, bench-top lab furnaces. These furnaces will be used as part of a precious metals recovery system for a worldwide manufacturer of catalytic converters, medical devices, and pollution environment controls. The assay division recycles many parts that were originally deployed as catalytic converters for diesel motors, medical components, and electrical parts. The project is expected to be completed in the first quarter of 2022.
The precious metals are burned out of the existing product and placed in crucibles. The crucibles are heated in the L&L model GS1714 at temperatures between 1,800°F / 982°C and 2,200°F / 1,204°C. This allows any impurities in the metals to rise to the surface and be removed for further refinement.
The model GS1714 has an effective work zone of 10” high by 15” across by 13” deep. The furnace is designed to be placed on a benchtop or with an optional furnace stand. It has a Honeywell DCP50 program control and an overtemperature protection system. Solid-state relays drive the element circuit and Inconel sheathed thermocouples are included. There is a ¾” alloy outlet on top of the furnace to remove any binder or contaminates that may exist within the product. Special anti-corrosive paint helps in the harsh environment that the furnaces are required to operate. Part of the recovery process involves salt baths as well as other burnout processes located in the same vicinity as the assay furnaces.
Also available is the larger GS2026 with all of the same options as the GS 1714 but featuring a work zone of 18” wide by 12” high by 24” deep.
The model GS1714 is typically in stock at L&L and available for immediate delivery. L&L can ship even special GS1714 furnaces in about two weeks after receiving the order.
