Abstract
The invention discloses an auxiliary device of an electrical heating radiation tube. The auxiliary device comprises a flange plate and a central shaft, the flange plate and the central shaft are welded at the two ends of the electrical heating radiation tube respectively and are meanwhile arranged on the base of the furnace wall of a heating furnace, six holes are evenly formed in the flange plate and are evenly formed in the outer circle of the flange plate, and the hole diameter is 18.5mm. The auxiliary device of the electrical heating radiation tube further comprises an independent steel bar, the diameter of the steel bar is 16mm, and the length of the steel bar is 500mm. The six holes are evenly formed in the outer circle of the flange plate, after the steel bar and the holes are matched and arranged, the electrical heating radiation tube is manually rotated at fixed periods, the downward concave deformation of the electrical heating radiation tube can be reduced in the long-term heating and using process, the service life of the electrical heating radiation tube is prolonged and can be prolonged by 30%-50%, and meanwhile working and production efficiency is improved.
Description
Technical field
The invention belongs to radiant tube servicing unit technical field, be specifically related to a kind of for the heat treated electric heating radiant tube of sheet material servicing unit.
Background technology
The electric heating radiant tube is to adopt electrical heating elements heating electric radiant tube, electrical heating elements is arranged in electric radiant tube, utilize the principle of electric radiation by electric radiant tube, steel to be heated, heat-treat, in order to improve the efficiency of heating surface, electrical heating elements in electric radiant tube and the gap of electric radiant tube only have 8mm, electric radiant tube is long time continuous working, working temperature is up to 900-1100 ℃, the electric radiant tube at high temperature worked long hours, will produce some distortion, middle part at electric radiant tube produces recessed, being out of shape electric radiant tube and electric heating element when larger contacts with each other, affect production and application.
Summary of the invention
The above-mentioned technical problem existed in order to overcome the prior art field, the object of the invention is to, and a kind of servicing unit of electric heating radiant tube is provided, and extends the useful life of electric heating radiant tube, enhances productivity.
The servicing unit of electric heating radiant tube provided by the invention, described electric heating radiant tube is arranged on the pedestal of heating furnace furnace wall, servicing unit comprises ring flange and central shaft, ring flange and central shaft are welded on respectively the two ends of electric heating radiant tube, and be arranged on simultaneously on the pedestal of heating furnace furnace wall, on described ring flange, be evenly equipped with 6 holes, 6 holes are distributed on the cylindrical place of ring flange, and aperture is 18.5mm.The servicing unit of electric heating radiant tube also comprises an independent rod iron, rod iron diameter 16mm, length 500mm.
The servicing unit of electric heating radiant tube provided by the invention, its beneficial effect is, the cylindrical place of ring flange is evenly equipped with 6 holes, rod iron coordinates installation with hole after, regularly hand rotation electric heating radiant tube, can make the electric heating radiant tube in long-term heating use procedure, reduce concave deformation, extend the useful life of electric heating radiant tube, can improve 30%-50% the useful life of electric heating radiant tube, also improved production work efficiency simultaneously.
The accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of one embodiment of the invention;
Fig. 2 is the left side view of Fig. 1.
In figure, mark:
1. hole; 2. ring flange; 3. electric heating radiant tube; 4. central shaft.
Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the servicing unit of electric heating radiant tube provided by the invention is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the servicing unit of the electric heating radiant tube 3 of the present embodiment, described electric heating radiant tube 3 is arranged on the pedestal of heating furnace furnace wall, servicing unit comprises ring flange 2 and central shaft 4, ring flange 2 and central shaft 4 are welded on respectively the two ends of electric heating radiant tube 3, and are arranged on simultaneously on the pedestal of heating furnace furnace wall, on described ring flange 2, are evenly equipped with 6 holes, 6 holes are distributed on the cylindrical place of ring flange 2, and aperture is 18.5mm.The servicing unit of electric heating radiant tube also comprises an independent rod iron, rod iron diameter 16mm, length 500mm.
Above the electric heating radiant tube, be furnace roller, steel plate transmits on furnace roller, and the electric heating radiant tube adopts the principle of electric radiation, and heating is heat-treated to steel plate.The every continuous operation of electric heating radiant tube 3 is after 20 days, rod iron is inserted in the set hole of ring flange 1, and hand-turning 60 degree, effectively reduce the concave deformation that the electric heating radiant tube produces because of heating along clockwise direction, extend the useful life of electric heating radiant tube, also improved production efficiency.
