FIELD: heat treatment of metals and plastic metal working; combined process of annealing and hot drawing of wire made from refractory metals. SUBSTANCE: proposed device is made in form of muffle with longitudinal slot in its lower portion at the side; mounted at inlet of said muffle is burner with axis of working nozzle oriented at angle of 40-50 deg. relative to longitudinal axis of muffle; it is mounted at inclination of 3-10 deg. downward relative to level towards inlet; burner is mounted for motion along longitudinal slot of muffle. Proposed device provided for increase of productivity by 3 times. EFFECT: enhanced reliability; simplified construction; reduced usage of metal. 3 cl, 3 dwg, 2 tbl, 2 ex
