Elevator Hearth Furnace

Elevator Hearth Furnaces

Accessible Loading Beneath a Fixed Heating Chamber

An elevator hearth furnace lowers its insulated base for loading, then raises the complete load into the heating chamber. This bottom-loading arrangement gives operators access to position ceramic components, arrange setter stacks and inspect clearances before firing, without reaching through a front door.

Sintering Ceramics and Advanced Materials

Applications include firing alumina and zirconia components, electronic ceramics and other engineered materials. Heating elements arranged around the load support even heat distribution, with the firing cycle developed around binder content, section thickness and sintering requirements. Combined debinding and sintering processes require dedicated gas-flow and exhaust provisions.

A Hearth Designed for Your Load

We customize the usable chamber, lifting capacity, hearth layout and travel to suit product geometry and kiln furniture. Heating configuration, insulation and atmosphere options are matched to the process. Where production scheduling benefits, interchangeable hearths can allow one load to be prepared while another is firing.
