Cabinet Oven for Processing Ceramic ComponentsNo. 799 is an electrically-heated 1,382°F (~750°C) inert atmosphere cabinet oven from Grieve, currently used for processing ceramic components, prior to assembly. The 60 KW are installed in alloy wire high temperature plug heaters. Workspace dimensions are 38 in. wide x 38 in. deep x 50 in. high.

The unit has 12 in. thick insulated walls comprised of 2 in. of 1,900°F block and 10 in. of 10 lb. density rockwool. The oven has a type 304, 2B finish stainless steel interior and is equipped with a solenoid operated door lock.

A 3,000 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, ½ in. 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.
