Abstract
The utility model provides a follow-up furnace door which is arranged on a furnace body of a steekle mill. The follow-up furnace door comprises a furnace door body, hydraulic cylinders are arranged on the outer side of the furnace door body at intervals, the inner side of the furnace door body is filled with fireproof materials, one ends of the hydraulic cylinders are fixedly arranged on hydraulic cylinder head supports arranged on the outer side face of the furnace door body, and the other ends of the hydraulic cylinders are fixedly arranged on hydraulic cylinder tail supports on the furnace body. According to the follow-up furnace door, the furnace door can slide vertically along with changes of the diameter of a strip coil, and the defect of the poor sealing performance of a furnace opening is overcome on the premise of guaranteeing that the strip coil enters and comes out of a coiled furnace smoothly.
Description
Technical field
The utility model relates to one and is adapted to coiler furnace fire door before and after steekle mill, relates in particular to a kind ofly in the winding process of steekle mill, and the position of directive wheel can change and the servo-actuated fire door that changes along with winding diameter.
Background technology
On steekle mill production line, milling train working stand is divided in two parts, on it, be provided with the coiling machine with holding furnace, can under hot state, be embodied as the reversible rolling of coiled strip steel, but because band steel toe tail rolls low, the rapid heat dissipation of speed, the strip thickness deviation shutting out is large, again because the finish rolling time is long, secondary oxidation iron sheet is many, therefore surface quality is undesirable.
In the prior art, the steekle mill of rolled band steel, its band steel entrance fire door is all generally to use dull and stereotyped fire door, so just makes to be with steel afterbody can not enter into coiler furnace, low with the temperature that causes the end segment with steel band steel above, affect the rolling quality of afterbody section strip steel.
Summary of the invention
In order to address this problem, the utility model provides a kind of servo-actuated fire door, and this servo-actuated fire door has been realized fire door along with the diameter of the roll coil of strip changes and slides up and down, and ensures that the roll coil of strip passes in and out under the prerequisite of coiler furnace smoothly and overcome the poor defect of fire door sealing.
To achieve these goals, the utility model provides a kind of servo-actuated fire door, be arranged on the body of heater of steekle mill, comprise oven door body, the outside of oven door body is arranged at intervals with hydraulic cylinder, and the inner side of oven door body is filled with refractory material, wherein, one end of hydraulic cylinder is fixedly mounted on the hydraulic cylinder head support arranging on oven door body lateral surface, and the other end of hydraulic cylinder is fixedly mounted in the hydraulic cylinder aft mount on body of heater.
Preferably, the left and right sides of oven door body is fixedly installed directive wheel, and the left and right sides of oven door body is also arranged at intervals with guide rail, and directive wheel can move back and forth on guide rail.
Preferably, the both ends of guide rail are all fixed on fire door place, in one end of guide rail, are provided with pressed slider.
Preferably, between pressed slider and guide rail, be connected by adjusting bolt, this adjustment bolt can be adjusted the initial position of pressed slider.
Preferably, on hydraulic cylinder, be provided with displacement transducer.
Preferably, hydraulic cylinder is 2-4.
The advantage that the utility model has compared to prior art is, this servo-actuated fire door can better meet the insulation requirement of the operation of rolling, and can not affect back and forth passing through of winding; In addition, oven door body, guide rail, directive wheel, lifting hydraulic cylinder integrated design, compact conformation, facilitate automation control, be easy to repair and maintenance.
Brief description of the drawings
Fig. 1 is the structural representation of servo-actuated fire door in the utility model;
Fig. 2 is that Fig. 1 middle guide compresses schematic diagram.
Detailed description of the invention
Below, by exemplary embodiment, the utility model is specifically described.But should be appreciated that element, structure and the feature in an embodiment also can be attached in other embodiments valuably in the situation that further not narrating.
Referring to Fig. 1, it is the structural representation of servo-actuated fire door in the utility model.As shown in the figure, this servo-actuated fire door is arranged on the body of heater of steekle mill, comprises oven door body 1, is arranged at intervals with hydraulic cylinder 4 in the outside of oven door body 1, and preferably hydraulic cylinder 4 is 2-4, is arranged on the left and right sides of oven door body 1; The inner side of oven door body 1 is filled with refractory material, wherein one end of hydraulic cylinder 4 is fixedly mounted on the hydraulic cylinder head support 5 arranging on oven door body 1 lateral surface, the other end of hydraulic cylinder 4 is fixedly mounted in the hydraulic cylinder aft mount 6 on body of heater, on hydraulic cylinder 4, be also provided with displacement transducer (not shown), this displacement transducer can be realized servo-actuated fire door adjustable height and change with the diameter of stove volume.
With further reference to accompanying drawing 1, and in conjunction with Fig. 2, as shown in the figure, be fixedly installed directive wheel 2 in the left and right sides of oven door body 1, directive wheel 2 can move back and forth on guide rail 3, this guide rail 3 is disposed on the left and right sides of oven door body 1, the both ends of guide rail 3 are all fixed on the steel structure support at fire door place, in one end of guide rail 3, be provided with pressed slider 9, pressed slider 9 can do directive wheel 2 to compress along the direction of guide rail 3 and move, directive wheel 2 can continue to continue to move a certain distance to fire door internal direction under the effect of pressed slider 9 in the time that fire door drops to the limit like this, to ensure better sealing between fire door and fire door.Preferably, between pressed slider 9 and guide rail 3, be connected by adjusting bolt 10, this adjustment bolt 10 can be adjusted the initial position of pressed slider 9, and convenient adjustment is convenient to change.
In the time that servo-actuated fire door is arranged on body of heater, need by the angled installation of this servo-actuated fire door, can overcome like this deadweight produce directive wheel and guide rail between friction and the heat affecting of furnace mouth radiation.
Be appreciated that the utility model is described by some embodiment, those skilled in the art know, in the situation that not departing from spirit and scope of the present utility model, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present utility model, can modify to adapt to concrete situation and material and can not depart from spirit and scope of the present utility model these features and embodiment.Therefore, the utility model is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs in the scope that the utility model protects.
