Abstract
The utility model discloses a high-temperature hydrogen burning and sizing furnace, which comprises a furnace body. A heating pipe transversely passes through the furnace body. An electric heating wire is wound on the outer wall of the heating pipe in the inner cavity of the furnace body. A filament passes through the heating pipe. A hydrogen lead-in pipe is connected to the side wall at the front end of the heating pipe. A spiral cooling water channel is arranged in the pipe wall at the tail end of the heating pipe. A cold water inlet and a hot water outlet are respectively connected outside the cooling water channel. According to the high-temperature hydrogen burning and sizing furnace disclosed by the utility model, the hydrogen burning temperature is easy to control and keep; the structure is rational; and the annealing and sizing quality of the filament is increased.
Description
Technical field
The utility model relates to high temperature annealing in hydrogen atmosphere shaping furnace.
Background technology
Filament is the twinkler of incandescent-lamp bulb, is generally all formed by the tungsten filament spirally-wound.In order to make coiled filament typing and not oxidation, the typing of must in hydrogen-burning stove, annealing is called for short annealing in hydrogen atmosphere.Experiment shows, the height of annealing in hydrogen atmosphere temperature directly has influence on the life-span and the photoelectric parameter of incandescent-lamp bulb.Yet in existing production reality, tungsten filament annealing in hydrogen atmosphere temperature receives the influence of many factors, is difficult to keep constant.
The utility model content
The purpose of the utility model provides a kind of high temperature annealing in hydrogen atmosphere shaping furnace, annealing in hydrogen atmosphere easy control of temperature and maintenance, and reasonable in design has improved the annealing typing quality of filament.
The technical scheme of the utility model is following:
High temperature annealing in hydrogen atmosphere shaping furnace; Include body of heater, crossed heating tube in the body of heater, the heating tube outer wall that is arranged in the body of heater inner chamber is wound with electrical heating wire; Passed filament in the heating tube; Have access to hydrogen ingress pipe on the sidewall of heating tube front end, be provided with spiral helicine cooling water channel in the tube wall of the tail end of heating tube, cooling water channel is connected with cooling water inlet, hot water outlet outward respectively.
Described inboard wall of furnace body is provided with insulating brick.
The annealing in hydrogen atmosphere easy control of temperature and the maintenance of the utility model, reasonable in design has improved the annealing typing quality of filament.
Description of drawings
Fig. 1 is the structural representation of the utility model.
