Abstract
The utility model discloses an electric heating radiant tube auxiliary apparatus, comprising a flange plate and a central shaft which are respectively welded to two ends of an electric heating radiant tube and are meanwhile installed to the substrate of a heating furnace wall. Six holes are uniformly distributed on the flange plate and are all located at the excircle of the flange plate, the diameter of each hole being 18.5 mm. The electric heating radiant tube auxiliary apparatus also comprises a single steel bar with the diameter of 16 mm and the length of 500 mm. The excircle of the flange plate is distributed with the six holes, and the steel bar and the six holes are cooperatively installed; through rotating the electric heating radiant tube by hand at fixed periods, the concave deformation of the electric heating radiant tube can be reduced in a long term of heating use, the service life of the electric heating radiant tube can be prolonged by 30%-50%, and the production efficiency is also raised.
Description
Technical field
The utility model belongs to radiant tube servicing unit technical field, is specifically related to a kind of for the heat treated electric heating radiant tube of sheet material servicing unit.
Background technology
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 working 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 existing in order to overcome prior art field, the purpose of this utility model is, 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 the electric heating radiant tube that the utility model provides, 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 the pedestal of heating furnace furnace wall simultaneously, 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 the electric heating radiant tube that the utility model provides, its beneficial effect is, the cylindrical place of ring flange is evenly equipped with 6 holes, rod iron coordinates with hole after installation, and regularly hand rotation electric heating radiant tube, can make electric heating radiant tube in long-term heating use procedure, reduce concave deformation, in the useful life that extends electric heating radiant tube, can improve 30%-50% the useful life of electric heating radiant tube, also improved production work efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of an embodiment of the utility model;
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 the electric heating radiant tube that the utility model is provided 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 the pedestal of heating furnace furnace wall simultaneously, are evenly equipped with 6 holes on described ring flange 2,6 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 electric heating radiant tube, be furnace roller, steel plate transmits on furnace roller, and electric heating radiant tube adopts the principle of electric radiation, and to steel plate, heating is heat-treated.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 electric heating radiant tube produces because of heating along clockwise direction, extend the useful life of electric heating radiant tube, also improved production efficiency.
