HEATING FURNACE CHAMBER FOR HIGH-TEMPERATURE TREATMENT OF ROD PARTS Russian patent published in 2016 - IPC B23K20/26 B23K20/14 F27B13/06 

FIELD: technological processes.

SUBSTANCE: invention can be used for high-temperature treatment of rod parts, including for formation of composite, for example glass-metal, materials and articles by diffusion welding of glass and metal billets units. Heating furnace chamber treated parts housing is made of ceramics and comprises detachable bottom and cover. Housing walls by height are formed, at least, from two identical hollow modules installed on each other with possibility of their detachable electric connection to corresponding outputs of adjacent modules. Heating device is made in form of spiral, fixed on each module chamber housing inner surface. Bottom is made in form of flat disk equipped in its central part with coaxial cylindrical protrusion, with possibility of placing on it with gap of module chamber housing lower end. Housing cover is made in form of flat disc having through coaxial opening and equipped with coaxial annular protrusion, having cylindrical groove, which inner diameter is equal to diameter of jointed with it module chamber housing upper end cavity.

EFFECT: chamber ensures possibility of easy device adaptation for discharge of articles of different dimensions in height while maintaining high degree of chamber volume filling.
