Grieve’s No. 810 is a 500°F, gas-heated, two-zone belt conveyor oven currently used for curing aluminum pistons. Workspace dimensions measure 42" × 24 feet × 15" high.  The workload travels atop a 36"-wide, high-carbon-steel, flat-wire conveyor belt with ¼-hp motor drive, variable from 0.8" to 15" per min., and through an 18"-long open loading zone. It then proceeds through an insulated heat zone that is 36" long and features 2-hp, 2,000-cfm recirculated airflow; a 16"-long insulated, unheated vestibule; a 16-ft.-long insulated heat zone with 10-hp, 12,500-cfm recirculated airflow; a 12"-long open zone; a 36"-long cooling zone; and, finally, an 18"-long open unloading zone.

Each of the oven’s two heating zones features 350,000 Btu/hr. installed in modulating natural gas burners. An aluminized steel exterior houses 4" insulated walls, a Type 304 stainless steel interior with continuously welded seams in Zone One and aluminized steel interior in Zone Two. A 16"-diameter tubeaxial fan driven by a ¾-hp motor pulls room air through the cooling zone.

This unit also features doors at both ends of the workspace to contain heat, as well as push-button electric ignition and a recording thermometer.
