Abstract
The utility model discloses a radiant tube compensator convenient to be replaced. Two ends of the compensator and two ends of a tube body of a radiant tube which is connected with the compensator are respectively provided with flange plates, the flange plates at the two ends of the compensator are connected with the flange plates of the radiant-tube tube body through bolts. The flange plates are connected through the bolts, accordingly online fast replacing of the compensator is realized, shut-down time can be reduced by 8 hours each time, and unit operating rate is improved. Large amounts of repairing cost can be saved, and production cost is reduced. Simultaneously, damage to the radiant tube caused by processing modes including electric welding and gas welding is avoided, and service life of the radiant tube can be prolonged.
Description
Technical field
The utility model belongs to the machinery field, relates in particular to a kind of removable corrugated compensator of continuous annealing furnace that is applicable to the radiation pipe heating.
Background technique
At present, cold-rolled steel factory generally adopts continuous annealing furnace that the band steel is heat-treated in the world, and its heat form is to utilize mixed gas in the radiation pipe internal combustion, and heat radiation is arrived gas in the annealing furnace internally heated oven.Radiation pipe can produce the hose expansion distortion because of being in for a long time under 650-980 ℃ the high temperature, therefore be connected with corrugated compensator on the radiation pipe body, with the distortion of compensation because of expanding and producing.But compensator all has 10 in the condition of long-term dilatancy following every year approximately to be damaged, and also must change after the damage.General compensator Placement is all taked Type of Welding, need during replacing compensator is pulled down together with radiation pipe, and deliver to specialized factory's electricity consumption, gas welding cutting, and method such as welding is handled again.Its drawback is:
1, need to shut down the replacing radiation pipe, every shutdown is changed one of radiation pipe and is needed 8h, and directly influence production carries out smoothly;
2, need deliver to specialized factory and handle, not only formality is numerous and diverse, and the time spent is longer, and expense is bigger;
3, specialized factory takes electricity, gas welding cutting and soldering, can cause certain damage to the radiation pipe body, influences the working life of radiation pipe.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple in structure, is convenient to implement, can under non-stop-machine situation, change fast, thereby save rehabilitation expense, the service life of radiant tubes life cycle can online replacing radiation pipe compensator.
For this reason, the concrete solution taked of the utility model is:
A kind of radiation pipe compensator of being convenient to change is characterized in that, at the compensator two ends and radiation pipe body two ends be separately installed with flange plate, by bolt compensator two ends flange plate and radiation pipe body flange plate are linked together.
Simultaneously, be provided with the refractory seal pad at compensator two ends flange plate and radiation pipe body two ends flange plate jointing.
The beneficial effects of the utility model are:
Because the utility model changes compensator into flange plate bolt with radiation pipe body Placement and is connected, and can realize fast online replacement, thereby can reduce more than 8h dead time, has improved the unit operation rate at every turn; Can save a large amount of rehabilitation expenses, reduce production costs; Simultaneously, damage that electricity consumption, gas welding processing mode are caused radiation pipe, the working life of service life of radiant tubes have been avoided.
Description of drawings
The radiation pipe compensator structure figure of accompanying drawing for ease of changing.
Among the figure: radiation pipe 1, radiation pipe body 2, body flange plate 3, compensator flange plate 4, compensator 5, refractory seal pad 6, bolt 7.
Embodiment
By accompanying drawing as seen, radiation pipe 1 global shape is two " U " shape pipes that link together, and radiation pipe body 2 two ends that are positioned at radiation pipe 1 one sides are stretched out one section in opposite directions, and 5 of compensators are installed between radiation pipe body 2.The utility model is that a compensator flange plate 4 is respectively installed at the two ends of compensator 5, simultaneously body flange plate 3 is also installed at the two ends of radiation pipe body 2 respectively.Be to strengthen sealing effect, on body flange plate 3 and compensator flange plate 4 interfaces, add and be lined with refractory seal pad 6, adopt bolt 7 solid between body flange plate 3 and the compensator flange plate 4, compensator 5 and radiation pipe body 2 are firmly linked together being bolted.
Claims (2)
1. a radiation pipe compensator of being convenient to change is characterized in that, at the compensator two ends and radiation pipe body two ends be separately installed with flange plate, by bolt compensator two ends flange plate and radiation pipe body flange plate are linked together.
2. the radiation pipe compensator of being convenient to change according to claim 1 is characterized in that, compensator two ends flange plate and radiation pipe body two ends flange plate jointing are provided with the refractory seal pad.
