Drop Bottom Quench Furnace

Where are these furnaces used?

Drop-bottom quench furnaces are used for the solution heat treatment of aluminium alloys. They are designed to operate with tight uniformities from 150°C to 650°C for maximum flexibility to allow for aging and annealing. The drop-bottom furnace stands on a base so that a quench tank can be positioned directly below the furnace.

Because of the broad working temperature range, drop-bottom furnace plants allow complete T6 heat treatments, consisting of solution annealing, quenching, and artificial aging in just one furnace.

Drop bottom furnaces are typically used when very fast water quench times are required. The furnaces are designed to meet all requirements of Aerospace Material Specifications (AMS) AMS 2750E and AMS 2770N, NADCAP, RPS-953 and Boeing Aircraft (BAC) specifications. These furnaces are also used for solutionizing, ageing of structural parts, and in forging industries of aluminium alloys.

Features of Drop Bottom Quench Furnace

• The heavy-duty mechanism for quenching and load lifting.
• This furnace integrates solution heat treatment and quenching into one controllable operation.
• Clamping Door Seal – When closed, the doors are tightly clamped against the bottom of the furnace to prevent cold air leakage which can disrupt the temperature uniformity of the load and increase operating expenses.
• High-Velocity Air – High-pressure blowers provide faster heating rates and tighter temperature uniformity for varying load configurations and densities.
• Recirculating ventilation systems designed to provide large volume and high-velocity airflow through the work zone to ensure uniformity and efficient heat transfer to the load.
• It has a customized air distribution design that matches the airflow pattern requirements according to the product/load arrangement.
• The quench tank can be equipped with controlled heating to pre¬heat the quenching medium and/or a heat exchanger for cooling.
• Water or polymer quench tanks have a single stainless steel wall and have an integrated circulation system of the quenching medium for effective removal of energy from the charge.
