Abstract
The utility model relates to an annealing device, and particularly relates to a continuous annealing device for molybdenum wires. The device comprises a wire-releasing wheel and a wire-withdrawing wheel which are parallelly arranged; an annealing furnace is disposed between the wire-releasing wheel and the wire-withdrawing wheel; a molybdenum wire is winded between the wire-releasing wheel and the wire-withdrawing wheel; the molybdenum wire passes through the annealing furnace; an electrical contact is disposed in the annealing furnace; the electrical contact is externally connected with a power supply system; a nitrogen inlet tube is introduced into the annealing furnace. The continuous annealing device for molybdenum wires is simple in structure, easy to operate, and good in stability, and is energy-saving.
Description
Technical field
The utility model patent relates to a kind of annealing device, relates in particular to a kind of continuous annealer that is used for molybdenum filament.
Background technology
After the molybdenum filament process multi-pass stretch process, owing to work hardening causes that resistance to deformation increases, plasticity reduces, so the process annealing of necessary process improve its processing characteristics to eliminate internal stress in the present prior art.
The annealing way that adopts at present has 3 kinds: a kind of is intermittent type annealing under hydrogen shield, uses not electric furnace of box horse, the rolling molybdenum filament is placed on takes out after being incubated certain hour in the stove; Another kind is the continous way annealing under hydrogen shield, uses corundum electric tube furnace indirect heating; Also have a kind of Sweet natural gas or direct-fired continuous oxygen annealing of liquefied gas of being to use.
What preceding two kinds of annealing way adopted is electrically heated, all must use the hydrogen shield molybdenum filament not oxidized, and the electric furnace energy consumption is big, use hydric safe property is poor; A kind of annealing way in back relies on combustible gas and pressurized air, and cost is high, and anneal uniformity is poor, poor working environment.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and the continuous annealer that is used for molybdenum filament of save energy.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of continuous annealer that is used for molybdenum filament; Comprise parallel placement put a silk wheel and a wire drawing wheel, described putting between silk wheel and wire drawing wheel is provided with lehre, described putting between silk wheel and wire drawing wheel is wound with molybdenum filament; Described molybdenum filament passes lehre; Be provided with electrical contact in the described lehre, the external power supply system of described electrical contact, feeding in the described lehre has nitrogen inlet tube.
The mode that adopts molybdenum filament directly to switch on and heat is set the electrical contact spacing, regulates current/voltage and receives a speed, annealing temperature and time that acquisition needs.Electrical contact adopts graphite (being used for crin annealing) or tungsten cotton (being used for filament annealing); Feed the not oxidation of nitrogen protection molybdenum filament in the lehre; Utilize waste heat to form the rete that is easy to apply lubricant at surface of molybdenum wire under.
Advantage that is reached and effect: the annealing way that has changed traditional use hydrogen shield.Use hydrogen is dangerous, and is inflammable and explosive, and nitrogen safety.The hydrogen cost is high, and the nitrogen price is lower than the over half of hydrogen; Electric furnace indirect heating with traditional is compared, and present method power consumption saves 50%, and production efficiency improves more than 30%; Combustible gas heating with traditional is compared, and present method is not used combustible gas, and the annealing operation is easy to control, good stability, the shortcoming of having avoided combustible gas to heat.
As preferably, the left end and the right-hand member of described lehre are respectively equipped with electrical contact, and electrical contact is crossed in described molybdenum filament cross-under.
As preferably, described nitrogen inlet tube is located at the interposition of lehre.
Therefore, the continuous annealer that is used for molybdenum filament of the utility model, simple in structure, easy to operate, good stability, save energy simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
