Sink Manufacturer Orders Humpback Annealing Furnace
Gasbarre Thermal Processing Systems manufactured and commissioned a humpback annealing furnace for a worldwide manufacturer and distributor of stainless steel sinks. The gas-fired, continuous furnace, which was custom-designed to meet the company’s strict process requirements, measured 106 feet long with a belt width of 32 inches. It is equipped with six heating zones that can heat up to 2200°F. The sink manufacturer wanted to increase production by up to 50%. A belt speed of 51 inches per minute was chosen to achieve that goal.
To aid in keeping the length of the furnace as short as possible, Gasbarre supplied four Hypercooler accelerated cooling units that also helped eliminate the effects of stainless steel sensitization. A closed-loop water-cooling system was also supplied. Gasbarre installed a Honeywell HC900 HMI to control all functions of the furnace and provide a large selection of data points for analysis and trending.
