In order to meet the casting requirement, the refractory material for manufacturing the side sealing plate needs to have the characteristics of good lubricity, poor molten steel wettability, high hardness and high melting point. However, since the side seal plates have a lower thermal conductivity than the casting rolls, the side seal plates tend to freeze cold steel on their surfaces, which can affect the quality of the cast strip. In order to minimize the influence of the temperature drop of the side sealing plates on the casting belt, the side sealing plates need to be preheated before casting, and the heated side sealing plates need to be put into casting operation as soon as possible so as to reduce the temperature drop of the side sealing plates in the installation process of the side sealing plates.

Detailed Description
The present invention is described in detail below with reference to the attached drawings.
As shown in fig. 1, the invention discloses a device for mounting a side sealing plate for twin-roll thin-strip continuous casting, which is used for fixedly attaching the side sealing plate 1 to the end surface of two casting rolls 12 positioned on the same side, so that the side sealing plate 1 and the casting rolls 12 can jointly form a molten steel bath with closed periphery. This side seal board 1 installation device includes:
a positioning device 3 having a receiving space for receiving and positioning the side sealing plate 1;
a drive means 2 for driving the positioning means 3 in a linear movement in a direction of the casting rolls towards and away from the ends of the casting rolls 12;
and a control system for regulating and controlling the moving position of the positioning device 3 through the driving device 2 so as to enable the side seal plates 1 to be attached to or detached from the end parts of the casting rolls 12.
Further, the control system comprises a processor 10 and a position sensor 9 for monitoring the movement position of the positioning device 3. The position sensor 9 is electrically connected to the processor 10 so that it can feed back position information of the positioning device 3 to the processor 10 in real time or at regular time. For example, the user presets the installation position of the positioning device 3 in the processor 10 according to the installation point position of the side sealing plate 1, and sends a signal to the processor 10 when the positioning device 3 moves to the installation position under the driving of the driving device 2, so that the processor 10 controls the driving device 2 to stop the movement of the positioning device 3 and keep the positioning device at the position.
Preferably, the control system further comprises pressure sensors 8 for sensing the pressure between the side closure plates 1 when they are brought into abutment with the ends of the casting rolls 12. The pressure sensor 8 is electrically connected to the processor 10 so that it can feed back a pressure value to the processor 10 in real time or at regular time, so that the processor 10 can determine whether the side seal plate 1 and the casting roll 12 are closely attached to each other according to the received pressure value. The user can predetermine the pressure value when closely laminating between the terminal surface of side seal board 1 and the casting roll 12 in treater 10 according to actual conditions specifically, makes treater 10 accessible comparison pressure sensor 8 real-time detection's the pressure value between the terminal surface of side seal board 1 and the casting roll 12 and whether unanimous with the pressure value of predetermineeing to judge whether closely laminating of terminal surface of side seal board 1 and the casting roll 12. If the pressure value detected by the pressure sensor 8 is smaller than the preset pressure value, the processor 10 determines that the side sealing plates 1 are not tightly attached to the end surfaces of the casting rolls 12, so that the control driving device 2 continues to drive the positioning device 3 to move towards the end surfaces of the casting rolls 12, or the driving device 2 increases the driving force to continue to drive the positioning device 3 to move so as to enable the positioning device 3 to be tightly attached to the end surfaces of the casting rolls 12, until the pressure value between the side sealing plates 1 and the end surfaces of the casting rolls 12 is detected to reach the preset pressure value. If the pressure value detected by the pressure sensor 8 is the same as the preset pressure value, the processor 10 determines that the side sealing plates 1 and the casting rolls 12 are in close contact, and adjusts and controls the driving device 2 to keep the existing driving force so as to continuously drive the positioning device 3 and position the positioning device 3, that is, the driving device 2 continuously applies the driving force to the positioning device 3 so as to keep the side sealing plates 1 and the casting rolls 12 in close contact, so that the positioning device 3 is constantly subjected to the reverse thrust which is equal to the driving force value and is applied to the side sealing plates 1 by the end surfaces of the casting rolls 12, and the positioning effect is achieved.
The driving device 2 in this embodiment is a driving cylinder (of course, the driving device 2 may be another linear driving mechanism). The position sensor 9 is arranged on the cylinder body of the driving oil cylinder, and the pressure sensor 8 is arranged at one end, facing the casting rolls 12, of the piston rod of the driving oil cylinder and is fixedly connected with the positioning device 3. The processor 10 is an external component which regulates the drive cylinder via a servo valve 11 which is electrically connected thereto and is simultaneously connected to the drive cylinder. That is, the processor 10 controls the hydraulic oil flowing into the driving cylinder by regulating the opening degree of the servo valve 11, and further controls the movement speed of the piston rod, so as to achieve the effect of regulating the driving force of the driving cylinder.
Referring to fig. 2 to 4, the positioning device 3 is a supporting base including a plurality of stoppers and a mounting plate 4 parallel to the end surface of the casting roll 12. The end of the piston rod of the driving cylinder, which is provided with the pressure sensor 8, is connected with the side of the mounting plate 4, which is far away from the casting rolls 12. The plurality of limiting members are arranged on the mounting plate 4 in a surrounding manner to form the accommodating space for accommodating and positioning the side sealing plate 1 in cooperation with the mounting plate 4. I.e. the side closure plates 1 are held against the mounting plate 4 by respective retaining members so as to be held in a position parallel to the end faces of the casting rolls 12. When the supporting seat with the structure is adopted to install and position the side sealing plate 1, the operation is simple and quick, when the side sealing plate 1 is installed, the side sealing plate 1 can be installed and positioned only by vertically inserting the side sealing plate into the accommodating space through a manipulator, and extra fixing pieces such as ceramic bolts and the like do not need to be arranged; when the side sealing plate 1 is replaced or moved, the side sealing plate is pulled out of the accommodating space through the manipulator, so that the side sealing plate is very quick and convenient, and the defect of large temperature drop of the side sealing plate 1 due to long positioning time is effectively overcome. (manipulators and other peripheral fixtures are not referred to herein and are therefore not described further.)
Preferably, the shape of the mounting plate 4 is matched with that of the side sealing plate 1, so that the mounting plate 4 and the side sealing plate 1 can be well attached together, that is, the contact area of the two is increased to the greatest extent while saving materials, so that when the piston rod of the driving cylinder applies a jacking force (i.e., a driving force) to the mounting plate 4, the mounting plate 4 can almost completely transmit the jacking force to the side sealing plate 1, the loss of the force is reduced, and therefore, the jacking force can ensure that the side sealing plate 1 and the casting roll 12 are closely attached, that is, the pressure value between the end surfaces of the side sealing plate 1 and the casting roll 12 meets the preset requirement.
With reference to fig. 2, the side sealing plate 1 in this embodiment is approximately shaped like an inverted triangle, in which two sides of the triangle (i.e. two sides respectively connected to the bottom side of the triangle) are both concave inwards to form an arc.
The locating part includes tray 5, two embrace claw 6 and two arc limiting plate 7. The support block 5 is arranged at the bottom of the side sealing plate 1 and used for supporting the side sealing plate 1; the two holding claws 6 are respectively arranged at the tops of the two sides of the side sealing plate 1 to limit the side sealing plate 1, and mainly limit the position of the side sealing plate 1 in the direction vertical to the plate surface of the mounting plate 4, and for the convenience of hoisting the side sealing plate 1 to the supporting seat, the distance between the holding claws 6 and the mounting plate 4 is slightly larger than the thickness of the side sealing plate 1, so that when the side sealing plate 1 is positioned in the supporting seat, a certain gap is required to be reserved between the side sealing plate 1 and the holding claws 6, and in the embodiment, the gap between the side sealing plate 1 and the holding claws 6 is at least 1 mm; two arc limiting plates 7 are respectively arranged in the middle of two sides of the side sealing plate 1, namely an arc limiting plate 7 is arranged between the supporting block 5 and each holding claw 6, the arc radius of the arc limiting plate 7 is slightly larger than that of the arc side edge of the side sealing plate 1, and if the difference between the two radii is 0.5mm-1mm, the side sealing plate 1 can be conveniently installed. Further, the arc-shaped stopper plate 7 is provided mainly for restricting the position of the side seal plate 1 in the direction parallel to the plate surface of the mounting plate 4 and preventing the displacement thereof. Two embrace claw 6 and two equal symmetry settings of arc limiting plate 7 in this embodiment to better spacing side seal board 1. In this embodiment, when the side sealing plate 1 is installed in the supporting seat, a gap of not less than 0.5mm is maintained between the two arc-shaped limiting plates 7 and the side sealing plate 1. In addition, the support block 5, the holding claw 6 and the arc limiting plate 7 are made of high-temperature resistant materials, such as ceramic or high-temperature resistant alloy.
In order to make the side seal plates 1 fit the end surfaces of the casting rolls 12, the side seal plates 1 are required to be protruded with the arc-shaped limiting plates 7 and the supporting blocks 5 towards the casting rolls 12 when they are installed in the supporting seats, in this embodiment, the side seal plates 1 are protruded with the supporting blocks 20mm towards the casting rolls 12. Meanwhile, as shown in fig. 8, when the side seal plates 1 are fitted to the end surfaces of the casting rolls 12, both the clasps 6 are located on the upper portions of the roll surfaces of the casting rolls 12 (the upper portions are shown in the figure), so as to prevent the clasps 6 from contacting the casting rolls 12 and affecting the sealing effect of the side seal plates 1.
The invention also discloses a method for installing the side sealing plates by adopting the device for installing the double-roller thin-strip continuous casting side sealing plates, namely a method for installing the side sealing plates 1 on the end surfaces of the casting rollers 12 by the installation device and putting the side sealing plates into casting use, which comprises the following steps:
1) adjusting the processing mode of a processor 10 in the control system to a position control mode which mainly determines whether to regulate and control the driving device 2 (the driving device 2 in the embodiment is a driving oil cylinder, and hereinafter referred to as a driving oil cylinder) according to whether the position of the positioning device 3 monitored in real time by the comparison position sensor 9 is a preset position, and then presetting a first preset position as an installation position and a second preset position as an adjustment position in the processor 10, so that when the positioning device 3 moves to the installation position and the adjustment position, the processor 10 can rapidly adjust the servo valve 11 according to a position signal fed back by the position sensor 9 to control the driving oil cylinder to stop driving, namely, the positioning device 3 stops at the installation position or the adjustment position; in the embodiment, the position of the adjusting position is the position where the distance between the side sealing plates 1 and the end surfaces of the casting rolls 12 is 2mm-10 mm;
2) as shown in fig. 5, when the device 3 to be positioned is positioned in the installation position, an operator installs the side sealing plate 1 in the positioning device 3 by a manipulator or other equipment;
3) as shown in fig. 6, after the side seal plates 1 are installed in the positioning device 3, the processor 10 continues to control the driving cylinders to drive the positioning device 3 to move from the installation position to the adjustment position adjacent to the end of the casting roll 12 and stop;
4) the processing mode of the processor 10 is adjusted to be in the position control mode and the pressure control mode which can judge whether to regulate and control the driving oil cylinder according to the comparison that whether the detected contact pressure value between the side seal plates 1 and the end surfaces of the casting rolls 12 is a preset pressure value (namely, the processor 10 is compatible with the position control mode and the pressure control mode at the moment), position data of the position where the positioning device 3 is located when the side seal plates 1 are fitted to the end faces of the casting rolls 12 are then preset in the processor 10 (this position is defined as a third predetermined position as a casting position in the present embodiment), and presetting a first pressure value F1 between the side sealing plates 1 and the casting rolls 12 when the positioning device 3 moves to the casting position and a second pressure value F2 with the pressure value being larger than F1 in the processor 10, so that the processor 10 can correspondingly adjust the driving force of the driving oil cylinder by adjusting the opening degree of the servo valve 11 according to the magnitude of the pressure values F1 and F2; the step is arranged to drive the positioning device 3 to move by a driving force which is matched with preset pressure (namely a first pressure value F1 and a second pressure value F2) so as to enable the side sealing plates 1 to be correspondingly attached to the end surfaces of the casting rolls 12 when the distance between the side sealing plates 1 and the end surfaces of the casting rolls 12 is smaller, compared with the mode that the positioning device 3 is driven by the driving force to move from the installation position, the driving force can be more accurately controlled, and the condition that the side sealing plates 1 are damaged due to larger collision force generated between the side sealing plates 1 and the casting rolls 12 is effectively avoided; in addition, in order to avoid the temperature reduction of the side sealing plate 1, the time for the positioning device 3 to stay at the adjusting position is usually 5s-10 s;
5) after the processor 10 finishes the mode adjustment and the casting preparation work is finished, the casting system sends an action command to the processor 10, at this time, the processor 10 quickly adjusts the servo valve 11, so that the driving oil cylinder drives the positioning device 3 according to the driving force preset by the corresponding pressure value F1, and the positioning device moves to the casting position attached to the casting roller 12;
as shown in fig. 7, when the position sensor 9 detects that the positioning device 3 moves to the casting position, and the pressure sensor 8 detects that the pressure value between the end surfaces of the side sealing plates 1 and the casting rolls 12 is F1, the processor 10 adjusts the servo valve 11 according to a preset second pressure value F2, so that the driving force applied by the driving oil cylinder to the positioning device 3 is gradually increased to increase the contact pressure between the end surfaces of the side sealing plates 1 and the casting rolls 12, and when the pressure sensor 8 detects that the pressure value between the end surfaces of the side sealing plates 1 and the casting rolls 12 is F2, the processor 10 adjusts and controls the driving oil cylinder to keep the pushing force constant and continuously push the positioning device 3, at this time, the side sealing plates 1 are tightly and stably attached to the end surfaces of the casting rolls 12.
Further, when the side seal plates 1 are tightly attached to the end surfaces of the casting rolls 12, that is, when the pressure value therebetween is F2, in order to position the side seal plates 1, the driving cylinders need to provide a permanent pushing force to the positioning devices 3 so that the side seal plates 1 are tightly attached to the end surfaces of the casting rolls 12 at any time, specifically, the following two methods can be adopted:
1) the processor 10 is enabled to correspondingly adjust the opening angle of the servo valve 11 by comparing the quantity relation between the pressure value fed back by the pressure sensor 8 in real time and the second pressure value F2, so that the driving oil cylinder provides a top thrust force (or at least a top thrust force of F2) which can enable the pressure value between the side sealing plates 1 and the end surfaces of the casting rolls 12 to be constant to be F2 to the positioning device 3, and further the side sealing plates 1 are positioned;
2) the operator prestores the precise position of the positioning device 3 (which may have a slight position error with the casting position, but the position error is within a normal error range) when the pressure value between the side sealing plates 1 and the casting rolls 12 is F2 in the position sensor 9 and the processor 10, so that the processor 10 correspondingly adjusts the servo valve 11 by comparing the detected data fed back by the position sensor 9 in real time with the predetermined position, so that the driving cylinder can provide adaptive driving force to the positioning device 3 according to the actual position of the positioning device 3, and the positioning device 3 is constantly positioned at the pressure value between the casting rolls 12 and the side sealing plates 1 of F2.
Preferably, since the casting rolls 12 may periodically generate a certain structural change during operation, in order to match the structural change of the casting rolls 12, an operator may preset a time period in the processor 10 according to the change cycle of the casting rolls 12 (of course, time control may be performed by other mechanisms, the preset time period in this embodiment is 1min-5min), and then the pressure value between the side sealing plates 1 and the end surfaces of the casting rolls 12 is constantly F2 in the time period, when the time period expires, the processor 10 adjusts and controls the driving cylinders 2 to gradually reduce the pushing force exerted on the positioning devices 3, so that the pressure value between the side sealing plates 1 and the end surfaces of the casting rolls 12 is gradually reduced, and when the pressure value between the side sealing plates is reduced to F1, the processor 10 adjusts and controls the driving cylinders 2 to drive the positioning devices 3 with a driving force corresponding to the pressure value F2 so that the side sealing plates 1 are tightly attached to the end surfaces of the casting rolls 12, when the pressure value between the side seal plates 1 and the positioning device 3 is F2, the processor 10 continuously adjusts and controls the driving oil cylinders 2 to keep the pressure value between the side seal plates 1 and the positioning device 3 at F2 in the time period, and the process is repeated, so that the pressure value between the side seal plates 1 and the end faces of the casting rolls 12 is periodically changed between F1 and F2.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
