Abstract
The utility model relates to a well type mo wire annealing furnace, comprising an electrical heating layer and a heat-insulating layer forming a furnace chamber in proper order ento-ectad. The well type mo wire annealing furnace is mainly characterized in that a chamber door is arranged on the top end of the furnace chamber; when fetching or taping material, the mo wire basically does not touch the wall of the furnace chamber so that the furnace tube is free from wear, and the furnace has a long service life. When an electric thermocouple is inserted into the furnace chamber from the chamber door, the electric thermocouple can be inserted into the center position of the furnace and the mo wire coil to make the monitoring temperature more accurate, and the furnace chamber is cylinder type and suitable for the mo wire coil to save space and energy. Compared with the box-annealing furnace, the annealed quality of the mo wire used in the well type mo wire annealing furnace is enhanced highly and the annealing cost is reduced greatly.
Description
The utility model relates to a kind of annealing furnace.
The used process annealing stove of tungsten industry is cabinet-type electric furnace at present, the boiler tube horizontal positioned, and hearth door is at the burner hearth front end, and burner hearth is cuboid, and thermopair inserts in the burner hearth from the back or the top of burner hearth, and thermo electric material is a nichrome wire.The shortcoming of its existence is: owing to pick and place material continually, burner hearth bottom and molybdenum filament friction cause the boiler tube wearing and tearing, the work-ing life of having reduced boiler tube; Convenient for picking and placeing material, thermopair is difficult to insert the burner hearth mid-way, and the observing and controlling furnace temperature is difficult to accurately; Because molybdenum filament is to put into circle material form, square burner hearth has redundant space, increases energy expenditure; Use electrical heating wire, make complexity, the life-span is short; Advance the hydrogen pipe and enter from the burner hearth back, the flow of hydrogen hour, burner hearth bottom is prone to negative pressure, enters air, causes bottom molybdenum filament oxidation.
The purpose of this utility model provides a kind of well formula annealing furnace, is particularly suitable for the annealing of molybdenum filament, and in the work-ing life that can improve boiler tube, thermometric is accurate, and is energy-conservation, molybdenum filament annealing quality height.
Well formula molybdenum filament annealing furnace of the present utility model forms burner hearth by electric heating layer and thermal insulation layer from inside to outside successively, also comprises being passed into advancing the hydrogen pipe, be inserted into the thermopair in the burner hearth in the burner hearth, it is characterized in that hearth door is positioned at the burner hearth top.
Above-mentioned burner hearth is preferably right cylinder, because molybdenum filament is with the annealing of circle material form, with circle material fit, saves the space like this, reaches energy-conservation.
Thermopair can insert in the burner hearth from hearth door, because molybdenum filament is with the annealing of circle material form, thermopair is convenient to insert burner hearth and circle material mid-way, makes the observing and controlling temperature more accurate.
Hydrogen enters burner hearth from burner hearth bottom, and the easier hydrogen that makes is full of whole burner hearth, avoids the oxidation of molybdenum filament.
Electric heating layer preferably vertically inserts the nickel chromium triangle clavate that is arranged in series and becomes in boiler tube.The one, easy to make, two are to use the life-span long.The inwall of burner hearth is exactly a boiler tube, and the one, the protection an electric heating element, the 2nd, be convenient to seal hydrogen.
Hearth door is located at the top, is the well formula, and when picking and placeing material, molybdenum filament does not contact substantially with hearth wall (boiler tube), and boiler tube is not frayed, long service life.
Below in conjunction with the embodiment description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A view.
Among the figure: hydrogen pipe 7 fire doors 8 burner hearths 9 furnace shells are advanced in 1 thermopair, 2 thermal insulation layers, 3 boiler tubes, 4 nickel chromium triangles rod, 5 holes 6
The nickel chromium triangle rod 4 that diameter is 6 millimeters vertically is inserted in the hole 5 in the corundum boiler tube 3, is series system.Boiler tube is cylindrical, and the furnace wall of nickel chromium triangle rod 4 peripheries is thicker, the intensity height, and boiler tube 3 bottoms do not add an electric heating element.Hydrogen enters burner hearth by burner hearth bottom, 900～1100 ℃ of furnace temperature.Outside the thermal insulation layer 2 is furnace shell 9.
Advantage of the present utility model:
Improved the service life of boiler tube, thermocouple temperature measurement is accurate, and is energy-conservation, carried than the annealing quality of box-annealing furnace molybdenum filament Height greatly reduces molybdenum filament annealing cost already.
