No. 799 is an electrically-heated 1382°F(~750°C) inert atmosphere cabinet oven from Grieve, currently used for processing ceramic components, prior to assembly. 60KW are installed in alloy wire high temperature plug heaters. Workspace dimensions are 38” wide x 38” deep x 50” high.
The unit has 12” thick insulated walls comprised of 2” of 1900°F block and 10” of 10lb. density rockwool. The oven has a type 304, 2B finish stainless steel interior and is equipped with a solenoid operated door lock.
A 3000 CFM, 3-HP alloy recirculating blower provides horizontal airflow to the oven and a 325 CFM cooling blower pulls room air through the air jacket on the inner oven for additional cooling.
An inert atmosphere oven requires a pressure regulator, flow meter, pressure gauge and internal high temperature gasket. Also needed was a bellow type seal in the doorway throat area, 1/2” thick silicone rubber atmosphere seal and blower shaft seal. Positive latching door hardware, adjustable offset door hinges and an outlet with pressure relief were added as well. To keep gas from escaping, the interior seams were welded gas-tight and all wall penetrations fitted with compression fittings.
No. 908 is a natural gas-heated, heavy-duty box furnace from Grieve, currently used at a commercial heat treater for various applications. Maximum operating temperature is 2000°F and the workspace dimensions measure 48” W x 48” D x 48” H. 1,000,000 BTU/HR are installed in four (4) modulating natural gas burners with a floor-mounted combustion air blower (shown in photo) onboard.
This Grieve furnace features 7” thick walls, comprising 5” of 2300°F firebrick and 2” of 1700°F ceramic fiber insulation, plus a 7” thick floor made from 4-1/2” of 2300°F firebrick and 2-1/2” of 1900°F block insulation. Additionally, a firebrick plate hearth supported by firebrick piers is provided.
