No. 982 is a 1,000 F, electrically heated rotary hearth oven from The Grieve Corporation, currently used for heat treating machined metal shafts at a customer™s facility. Workspace dimensions measure 24" W x 11" D x 30" H with a 26-inch diameter hearth constructed from overlapping steel plates with 24 pipes holding pin inserts to support the workpieces. 24 KW installed in Incoloy sheathed tubular heating elements provide power, while a 1,000 cfm, 1-hp recirculating blower provides radiant horizontal airflow to the workload. An additional cooling blower is mounted beneath the loading table to cool the parts in the front middle three positions of the hearth. The hearth is driven by a 1/4-hp motor through a gear reducer with torque limiting device, variable from 0.1 to 0.5 revolutions per hour. A loading table is provided in front of the oven to hold extra pin inserts (shown in photo). For more information visit www.grievecorp.com or call (847) 546-8225.
