The protective atmosphere isolation device in the continuous annealing furnace for cold-rolled strip steel. A furnace roll is installed under the strip steel passing line of two adjacent furnace sections in the furnace body, and a pair of sealing baffles are installed above and below the furnace roll; the upper and lower The head ends of the baffles are respectively flexibly connected with the fixed frames on the corresponding furnace walls, the end of the upper baffle is close to the strip steel, and the end of the lower baffle is close to the furnace roll; there is a transition furnace chamber between the two furnace rolls, and the top is provided with The furnace pressure control port is equipped with a furnace pressure control baffle driven by a cylinder. The utility model can mechanically isolate the protective atmosphere in adjacent furnace sections, and is easy to operate and control.
Description
(1) technical field: the utility model relates to a kind of heat treatment furnace, is specifically related to the protective atmosphere disrupter in the metallurgical industry cold-rolled steel strip continuous annealing stove.
(2) background technology: cold rolled strip is because the difference of steel grade and purposes, and that takes in annealing furnace has different modes such as recrystallize clean annealing, decarburizing annealing and nitriding annealing; For the cold rolled strip of some special kinds, in same stove, should finish the recrystallize clean annealing, also need simultaneously carbonization treatment, therefore each is different in different stove segment protect atmosphere, promptly is low dew point H in the primary reformer chamber
2With N
2Mixed atmosphere, be the H of high dew point in another section furnace chamber
2With N
2Mixed atmosphere; For preventing that furnace atmosphere from interpenetrating, disturbing, guarantee that quality product mainly takes the method that protective atmosphere flow and various parameter are regulated is controlled at present aborning, but it is very loaded down with trivial details to operate.
(3) summary of the invention: the purpose of this utility model just provides a kind of can mechanically the isolation protective atmosphere in the adjacent stove section, and is simple to operate, the protective atmosphere disrupter in the continuous annealing furnace that is easy to control.
The utility model be the band steel of adjacent two stove sections in body of heater by a furnace roller respectively is set under the line, be provided with a pair of sealing baffle furnace roller upper and lower; The head end of wherein going up lower baffle plate respectively with corresponding furnace wall on anchor flexibly connect, the end of overhead gage is near the band steel, the end of lower baffle plate is near furnace roller; One transition furnace chamber is arranged between two furnace rollers, and its top is provided with furnace pressure control mouth, and the furnace pressure control baffle plate by air cylinder driven is housed on the control mouth.
Owing to adopted above-mentioned disrupter, make the obstruct of the different protective atmospheres of the adjacent stove section control easily that becomes; In process of production, as long as to the furnace pressure P of adjacent stove section
1, P
3Reach the furnace pressure P of transition furnace chamber between the adjacent stove section
2Detect supervision, and control the aperture assurance P of furnace pressure control baffle plate all the time
2Less than P
1And P
3So just can guarantee that part shielding gas that two stove sections overflow all can overflow and is unlikely to enter other stove sections from furnace pressure control mouth.This point is especially for the shielding gas that requires quick refrigerative high tensile steel plate in annealing (front and back stove section 5%H
2, cooling section 75%-100%H
2) obstruct more seem very important, can accelerate speed of cooling and satisfy product requirement, make again safety be protected.
(4) description of drawings:
Fig. 1 is that the utility model is at the intravital structural representation of stove.
(5) embodiment:
Referring to Fig. 1, adjacent two stove sections are that the band steel of forehearth section 2, back stove section 3 respectively is provided with furnace roller 5,6 for 4 times by line in body of heater 1, and these furnace roller two ends are separately fixed at (not shown) on the bearing support of furnace wall, and can rotate synchronously by steel going along with; Be provided with sealing baffle 7 on the top of furnace roller, be provided with lower seal baffle plate 8 in the bottom of furnace roller, wherein the head end of upper-lower seal baffle plate respectively with corresponding furnace wall separately on anchor 9 flexibly connect, open when conveniently wearing band baffle plate allow thread a needle by.The terminal as close as possible band steel of last sealing baffle, but not the contact zones steel in order to avoid scratch the band steel; The terminal as close as possible furnace roller of lower seal baffle plate; for keeping lower baffle plate and horizontal direction at an angle to reach better seal; the vision slit (not shown) is set on body of heater usually observes; when in a single day baffle plate rotates to only angle when wearing band; promptly baffle position is locked by the outer control lever (not shown) of stove; such two pairs of sealing baffles and furnace roller form two active barriers, mechanically cut off the protective atmosphere of adjacent stove section.A transition furnace chamber 10 is arranged between two furnace rollers, and this furnace chamber top is provided with furnace pressure control mouth 11, and the furnace pressure control baffle plate 12 by the air cylinder driven (not shown) is housed on the control mouth.
