Drop Bottom Quench Furnace
JR FURNACE has a full range of Solution Heat Treatment Furnaces of batch capacity up to 25 MT for heat treatment of Aluminium and Alloy components for Aluminium Industries like Auto components, Cylinder Heads, Paminum Sheet, Aluminium Ingots, Conductors, and Aluminium Foils etc.
The Solution Heat Treatment furnaces are drop bottom type with the furnace supported on an elevated structure with the water quenching tank underneath to ensure quick quenching after desired heating as per the specific heat treatment cycle of solution treatment.
Hot air circulation inside the furnace is made by an efficient centrifugal or axial type recirculation fan, which can be with a two-speed motor or with a VFD drive.
The Drop Bottom Quench Furnace are of double wall construction with ceramic fiber blankets sandwiched between inner and outer wall for optimum insulation and minimum wall losses. We have full capability to offer complete control and instrumentation systems through PLC based or Hardware based logic controls.
These Drop Bottom Quench Furnace are of Circular/ Rectangular construction with insulated cover that hydraulically/electro-mechanically move sideways to ensure charging of Circular/ Rectangular workbasket from the loading platform through suspended wire-rope type hydraulically/electro-mechanically operated lifting and lowering mechanism.
The loading platform and the quenching tank are mounted on a hydraulically/electro-mechanically driven trolley above the ground level to facilitate quicker quenching (within 30secs), where in the trolley will move underneath the furnace with loading platform under the furnace for loading the charge material into the furnace by the lifting and lowering mechanism for desired heating and soaking.
Subsequently the quenching tank will move under the furnace for quenching after the desired heating and soaking. In case the permissible quenching time is little longer i.e. beyond 45 secs the furnace can also be offered with a cemented quenching tank below ground level with loading platform mounted on a trolley moving above the quench tank for desired loading and unloading.
These Drop Bottom Quench Furnace can be either electrically heated or fuel fired. The electrically heated furnaces are provided with resistive Strip/Wire heating elements located on the sidewall of the furnace.
The heating elements of the furnace are suitably divided into a number of heating zones and can be controlled through Contactor or Thyristor based control philosophy through PID controllers.
- Features & Specifications
Quench systems utilize either straight water or varying concentrations of glycol water mixtures and are temperature controlled to match final desired end results. Air quench options are also available.
Control systems visually monitor tank loading and automatic rack hooking operations keeping the operator away from the furnace and moving equipment.
Temperature uniformities meet MIL and aerospace specifications requiring +/- 5 degrees F of maximum temperature spread.
Drop Bottom Quench Furnace meet AMS-2750E heat treat requirements for temperature uniformity and precise heating of workloads.
Data acquisition systems monitor all phases of the process and are developed to send this information to the end user’s in house network. Local monitoring and live displays of in process information give operators real time useful information.

Frequently Asked Auestion
Details of Basket required in Drop Bottom Quenching Furnace?
For loading and unloading the charge in furnace, SS basket will be provided to transfer the hot charge immediately in the quenching tank through wire rope drive system.
How to generate the report for temperature data in the basis of Heat wise in quantity
Customer has to feed the Job No /Data in PLC/SCADA system for each cycle. The Temperature data will be generated.
