This practicality compares the effect that exists with the background art and is: the heating wire is prevented from being directly exposed inside the annealing furnace, and oil in the air is prevented from being attached to the heating wire, so that the heating wire cannot cause short circuit due to carbonization, and the service life of the heating wire is greatly prolonged.
Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a heating tube structure of a continuous annealing furnace.
[ background of the invention ]
When the existing continuous annealing furnace anneals a copper material, because the surface of the copper material has components such as oil, water and the like, in the annealing process, the oil component in the air is easy to carbonize and is attached to a heating wire, and after a certain amount of oil is accumulated, the heating wire is easy to short-circuit and burn, so that the annealing effect of the annealing furnace is influenced.
[ Utility model ] content
The utility model aims at overcoming the problems, and providing a heating tube structure of a continuous annealing furnace, which adopts the annealing furnace of the heating tube structure to avoid the problem of short circuit burning caused by heating wire carbonization.
In order to realize the above purpose, the utility model provides a heating tube structure of continuous annealing stove, it includes the body and locates the inside heating element of body, and the inside cavity that holds heating element that opens of body, the wherein one end opening of body, heating element includes the support and locates the heating tube on the support, and the support is located one of open-ended is served and is equipped with the portion of connecting electricity, connect electricity portion and heating tube electric connection.
In one or more embodiments, the bracket is further provided with a heat insulation structure at one end of the opening.
In one or more embodiments, the heat insulation structure is heat insulation cotton, the heat insulation cotton is sleeved on the support, and the outer surface of the heat insulation cotton is abutted against the cavity wall of the cavity.
In one or more embodiments, the electric connection part comprises a live wire end and a zero line end, and the live wire end and the zero line end are provided with connection holes.
In one or more embodiments, the heat pipes are uniformly arranged on the support.
In one or more embodiments, an expansion area is left between the inner side wall of the other end of the tube body opposite to the opening and the heating element.
This practicality compares the effect that exists with the background art and is: the heating wire is prevented from being directly exposed inside the annealing furnace, and oil in the air is prevented from being attached to the heating wire, so that the heating wire cannot cause short circuit due to carbonization, and the service life of the heating wire is greatly prolonged.

[ detailed description ] embodiments
In order to enhance the understanding of the present invention, the following detailed description is given with reference to the following embodiments and the accompanying drawings, which are only used for explaining the present invention and do not limit the scope of the present invention.
Referring to fig. 1-3, the present embodiment provides a heating tube structure of a continuous annealing furnace, which includes a tube body 1 and a heating element disposed inside the tube body 1, wherein the tube body 1 is cylindrical, a cavity for accommodating the heating element is formed inside the tube body 1, one end of the tube body 1 is open, the heating element is used for being pulled out or mounted through the opening, the heating element includes a support 2 and a heating wire 3 disposed on the support 2, the support 2 is provided with an electrical connection portion at one end of the opening, the electrical connection portion is electrically connected to the heating wire 3, when the heating wire 3 is powered on, heat emitted by the heating wire 3 is radiated to the cavity and to the outside of the tube body 1, so that the tube body 1 serves as a heating carrier, copper materials to be annealed are annealed, and carbonization of oil-containing gas in the furnace is prevented from being attached to the heating wire 3.
Referring to fig. 2, the heat insulation structure 4 is further arranged at one end, located at the opening, of the support 2, the heat insulation structure 4 is used for sealing the cavity and preventing heat from dissipating from the opening, preferably, the heat insulation structure 4 is heat insulation cotton, commonly called pearl cotton, and has the advantages of being good in heat insulation effect and low in price.
The electric connection part comprises a live wire end 5 and a zero wire end 6, and wiring holes 7 are formed in the live wire end 5 and the zero wire end 6, so that wiring can be conveniently conducted through the wiring holes.
The heating wires 3 are uniformly arranged on the support 2 to ensure that the pipe body 1 is uniformly heated and ensure the annealing effect of the annealing furnace.
The expansion region 8 is left between the inside wall of body 1 for the open-ended other end and the heating element, and when heater 3 generated heat, the inside temperature of cavity was very high, and support 2 and heater 3 have certain thermal expansion to extend, and reservation expansion region 8 can hold support 2 inflation part.
In addition to the above embodiments, the present invention may have other embodiments, and technical solutions formed by equivalent substitutions or equivalent transformations all fall within the protection scope of the present invention.
