5 - 10 Ton Physical Test Furnace
|
General specifications:
|
 5-10 Ton Hot press |
This 10 Ton hot press can be equipped with many options: a ceramic hot zone for operation in air (1650C max.), a graphite or metallic zone for operation in vacuum or inert gas (2300C max), diffusion pumping system, turbo pumping system, roughing pump, thermocouple or pyrometer temperature control, etc. The furnace comes equipped with an intuitive and easy to use computer interface, allowing full control of the furnace. In addition it provides data trends and storage, display and logging of alarms, unlimited recipe profiles for pressure control and temperature control, security, etc. The PC is an industrial flat panel PC mounted in the control console and is built to withstand harsh environments. The furnace can easily be converted to a batch furnace for production. A data acquisition package is supplied to easily document and research previous runs.

The chamber is loaded from the front and contains a Hot Zone with a 3.0" dia. x 6.0" high usable zone
and +/- 10C temperature gradient. The heating element is a 1/2-
1/2 split design allowing the a die body to
be inserted straight into the zone. The furnace chamber is
manufactured from doubled-walled stainless steel
welded together and polished for a clean finish and good vacuum integrity.
The hot zone assembly can be one of three choices: a graphite band element and rigid
fibrous graphite insulation pack, a Moly-D rod element and ceramic insulation pack, or a high temperature metal mesh heating element and layered metal shielding. In the hot press configuration the
maximum operating temperature is 2200C ( 1650C with ceramic zone). With the end plug
shields supplied to plug the top and bottom hot rod openings
the furnace can be used as a batch/sintering
furnace with operation temperatures to 2300C.

The Post and Platen Press frame with load train is designed and manufactured to withstand well over 10 tons of force. This Post & Platen Frame is fully adjustable in all directions. Unlike the standard welded "H" frame, this MRF design supports the chamber totally free of the load train and is fully adjustable. The support includes, four (4) independent post clamp collars, a top platen supporting the top mounted hydraulic cylinder, bottom platen supporting the lower dead rod, and adjustment bolts for the clamp collars and cylinder flange. The load train includes water-cooled stainless steel top and bottom cold rods, and . high strength top and bottom hot rods. The top rod has a 4.0" stroke and the top cold rod is sealed by a static O-Ring on a bellows assembly to provide a vacuum seal.
The Servo Hydraulic and Pressure Control System includes a 4.0" stroke hydraulic cylinder, a hydraulic power unit, a pressure gauge to monitor hydraulic fluid pressure, a load cell to measure and control pressure. The pump size and servo valve size are calculated to give a cylinder speed on the extend stroke of 30 inches per minute. Cylinder positional accuracy will be 0.001" and pressure accuracy of 1 lbs. Manual jog buttons are included on the PC to allow for manual control of the top ram for loading and unloading a specimen.

Power to the hot zone is supplied by a Three Phase SCR controlled power supply, including a circuit breaker, a contactor, an SCR to modulate the power to the hot zone, a main stepdown transformer matched to meet the heating element resistance, Volt and Amp Meters, and a set of water-cooled power cables to supply power to the furnace.
| Temperature and press control is accomplished with Programmable Logic Controller (PLC). The PLC is used to control temperature, the force (pressure to 1 lbs. accurate) or displacement (travel to 0.001" accurate), and other system components such as vacuum and gas. The pressure and temperature control programs can be synchronized. Since the instrument reads and controls travel, temperature, and pressure, other instruments can be eliminated thus simplifying operation and configuration.The controller interfaces with the PC and transmits the temperature,power, pressure, travel, |

A type "C" sheathed and coated thermocouple is supplied and can be used to measure the furnace temperature up to 2300C. When operating the furnace to temperatures above 1600 o C, control is automatically switched over to a Pyrometer.

The evacuation system consists of a Rotary Vane mechanical pump,
an electro-pneumatic
vacuum valve, vacuum gauge controller and vacuum gauge. This vacuum system will allow for operation in a vacuum environment (10-2 Torr range) A 4" or 6"diffusion pumping system or a turbo pumping system can be provided as well and can achieve vacuum levels down to 10-6 ( diffusion pumping system) and 10-7 Torr range ( turbo pumping system). A manual
valve is provided for leak checking or air releasing the
roughing line.
The gas system is supplied to provide an inert environment for the work samples during the heat and physical testing. The process Gas System (Argon): includes
solenoid-operated inlet valve, a Compound Gauge (30 P.S.I.G. x
30 in. Hg.), a gas flow meter, and a 2 P.S.I.G. outlet relief
valve to maintain a positive pressure. There is also a 5
P.S.I.G. over-pressure safety relief valve.

The Furnace Water cooling manifold consists of multiple circuits to adequately cool all the furnace parts and includes a strainer, pressure regulator, pressure gauge, water inlet and outlet manifold,
a water flow switch as a visual water flow indicator
with a flow interlock to protect the furnace in the event of a
water flow failure. This switch turns off power to the hot zone
contactor if water flow is below recommended minimum for a certain amount of time. Each part of the furnace is supplied with a separate cooling circuit that can be regulated by independent manual ball valves.
