PLANT FOR THERMAL PLASTIC HARDENING OF LARGE-SIZED ARTICLES Russian patent published in 2003 - IPC

Abstract RU 2219250 C1

FIELD: heat treatment of articles; hardening of large-sized articles such as turbine disks of gas- transfer units. SUBSTANCE: proposed plant includes gas burner and sprayer mounted on strut. Burner and sprayer are located separately at distance no less than 110 mm for longitudinal motion. Length of sprayers is selected from the following relationship: L_spr = (1,7-2,3)L_burn, where is length of burner. Strut is secured on frame provided with fasteners at its ends. EFFECT: enhanced efficiency. 2 cl, 4 dwg
