The Selas Horizontal Differential Hardening Furnace is specifically designed to harden the surface of large rolls quickly and accurately with a minimum of scale formation. Mounted on special rotating fixtures, the rolls are heated over their entire surface to uniform, controlled depths. This is a split-cylinder or clam-shell type furnace.
STANDARD FEATURES
Furnace arrangement and combustion equipment provide uniform, fast heating of the entire roll body surface.
Heating is confined to the roll body only. This assures the development of hard, wear-resistant body surface with maintenance of a tough fracture-resistant metal structure in the body core and journals.
The excellent turndown of the burners maintains the desired hardening temperature at the surface while heat penetrates to the desired depth below the surface.
Furnace design incorporates the required flexibility for accommodating the wide range of body diameters and lengths of the rolls.
Attributes of rapid heating and uniform temperature control are achieved through a proprietary Selas burner design allowing considerable turndown capability to accommodate substantial heating rate difference between heat up and hold cycle portions.
Furnace design features the required flexibility for accommodating the wide range of body diameters and lengths.
Rugged design and construction require minimal maintenance.
