[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. A fixed component is provided, which drives the laminating press frame to align with the bending position of the slab by controlling and adjusting the electric rail and the moving motor, and the supporting cylinder drives the supporting roller to fit the bottom of the slab to effectively support the slab. The laminating fixed cylinder drives the laminating press frame to deform, so that the laminating press frame can be adjusted according to slabs of different shapes, and has a wide range of applications. The lifting cylinder drives the lifting plate and the laminating press frame to descend, so that the bottom surface of the laminating press frame fits the top surface of the slab. The support of the supporting roller cooperates with the downward pressure of the laminating press frame to effectively fix the slab, and prevent the slab from moving during subsequent cutting, thereby improving the cutting quality. At the same time, the adjusting and moving motors can flexibly adjust the position of the laminating press frame according to the size of the slab, and has a wide range of applications.

[0026] The following electric rail, the following electric push rod and the transverse electric rail drive the dust collection box to move, so that the dust collection head always follows the movement of the cutting gun head. When cutting the slab, water is quantitatively sent into the evaporation box by controlling the first quantitative valve. The water flowing into the evaporation box evaporates quickly, and the blower conveys air to the dust collection box, the telescopic inner tube and the telescopic outer tube to accelerate the air flow inside the dust collection box, the telescopic inner tube and the telescopic outer tube. Under the action of the pressure difference, the external air drives the dust and harmful gas to flow through the dust collection head, the dust collection box, the telescopic inner tube and the telescopic outer tube in sequence into the dust collection box. The water vapor flows through the steam branch pipe, the steam tank and the collecting pipe in turn and enters the dust collection box. The water vapor contacts with the dust to absorb the dust. The hot water vapor touches the cold inner wall of the dust collection box and condenses into water droplets which fall into the dust collection box, separating the dust from the harmful gas. The device can effectively fix the slab while also making effective use of the heat emitted by the slab. The high temperature is used to evaporate the water to form water vapor, which absorbs the dust. When cutting the slab, dust and harmful gases are prevented from flying around, thus ensuring the health of the on-site workers.

[0027] 2. A cooling and fixing component is provided, which drives the lower pressing plate to descend through the lower pressing cylinder to press and fix the straight slab position, and cooperates with the fixing of the slab by the fitting pressing frame, which further enhances the fixing effect, further ensures the cutting stability and improves the cutting quality;

[0028] Clean water is delivered to the inside of the three-way pipe through an external water pump, and the clean water flows through the three-way pipe, the water supply main pipe and the water supply branch pipe in turn into the evaporation box, and the second quantitative valve is controlled to make the clean water drip into the evaporation tank in a quantitative manner. The water in the evaporation tank evaporates quickly, and the evaporated water vapor flows through the steam receiving branch pipe, the steam receiving main pipe and the steam supply pipe in turn into the steam tank, thereby increasing the steam volume in the steam tank, so that dust can be better adsorbed during subsequent dust collection, resulting in a better dust removal effect;

[0029] The driving motor and the transfer motor respectively drive the moving roller and the supporting roller to rotate, and transfer the cut slab. During the transfer process, the external circulation refrigerator delivers cold water to the circulating water pipe and the inside of the circulating water tank. The cold water flows through the water channel to cool the moving roller, reducing the accelerated wear of the moving roller caused by high temperature and extending the service life of the moving roller.

[0030] In summary, using the heat of the slab to evaporate water in the fixing assembly and the cooling fixing assembly can take away the heat from the slab. When the slab is stored, the subsequent cooling time is shortened, and the overall slab processing efficiency is accelerated. At the same time, the dissipated heat is effectively used for dust removal, and the energy utilization rate is higher. BRIEF DESCRIPTION OF THE DRAWINGS

The input ends of the mobile motor 206, the first metering valve 221, the adjusting electric rail 225, the following electric rail 226, the following electric push rod 227, the transverse electric rail 229, the blower 233, the drive motor 306, the second metering valve 317 and the transfer motor 323 are electrically connected to the output end of the external controller, and the input end of the external controller is electrically connected to the output end of the external power supply. Each electrical component is controlled by the external controller, which facilitates the automatic control of the device.

[0055] The working principle and use process of the present invention are as follows: first, the slab is placed on the top of the moving roller 201 in the middle of the assembly frame 1 on one side. Under the connection and driving action of the gear box 305, the driving motor 306 drives the moving roller 201 to rotate, thereby driving the slab to move. When the slab moves to the bottom of the bonding press frame 213, the driving motor 306 stops running, the electric rail 225 and the moving motor 206 are adjusted to start, and the electric rail 225 drives the limit rail 203 to move. At the same time, under the limiting action of the limit rail 203 on the moving slider 204, the moving motor 206 drives the moving slider 204 and the supporting suspension The frame 207 moves to align the laminating press frame 213 with the top of the slab, and then the support cylinder 321 drives the support roller 322 to fit the bottom of the slab to effectively support the slab. Then, the laminating fixing cylinder 210 drives the laminating press frame 213 to deform, so that the laminating press frame 213 can better fit the slab. At the same time, the lifting cylinder 208 drives the lifting plate 209 and the laminating press frame 213 to descend, so that the bottom surface of the laminating press frame 213 fits the top surface of the slab. The support of the support roller 322 cooperates with the downward pressure of the laminating press frame 213 to effectively fix the slab, prevent the slab from moving during subsequent cutting, and improve the cutting quality.

[0056] At the same time, the pressing cylinder 308 drives the pressing plate 309 to descend, and the pressing plate 309 presses down and fixes the straight slab position, further enhancing the fixing effect, further ensuring the cutting stability, and improving the cutting quality;

[0057] Next, the cutting gun cuts the slab, and the following electric rail 226, the following electric push rod 227 and the transverse electric rail 229 are started, and the following electric rail 226, the following electric push rod 227 and the transverse electric rail 229 drive the dust box 230 to move, so that the dust head 232 moves with the cutting gun head;

[0058] To ensure the quality of cutting, the hot-rolled slab is cut at a temperature of 800-900°C. The cutting gun will generate dust and harmful gases when cutting the slab. At this time, the laminating press frame 213 and the hot-rolled slab are laminated. The laminating press frame 213 and the evaporation box 215 are made of metal iron. Under the action of heat conduction, the evaporation box 215 is quickly heated. The external water pump delivers clean water to the inside of the water delivery pipe 219. The clean water flows through the water delivery pipe 219 into the water collection box 218, controls the first quantitative valve 221, and the clean water in the water collection box 218 flows through the branch water pipe 2 20 quantitatively flows into the evaporation box 215, and the water flowing into the evaporation box 215 evaporates quickly. The blower 233 is started, and the blower 233 delivers air to the dust box 230, the telescopic inner tube 235 and the telescopic outer tube 234, accelerating the air flow inside the dust box 230, the telescopic inner tube 235 and the telescopic outer tube 234, so that the pressure inside the dust box 230, the telescopic inner tube 235 and the telescopic outer tube 234 is lower than the pressure outside. Under the action of the pressure difference, the external air drives the dust and harmful gases to flow through the dust collector head 232, the dust collector head 234 in sequence. The box 230, the telescopic inner tube 235 and the telescopic outer tube 234 enter the dust box 237. At the same time, the pressure inside the evaporation box 215 is higher than the pressure inside the dust box 230. Under the action of the pressure difference, the water vapor flows through the steam branch pipe 223, the steam tank 222 and the collection pipe 231 in sequence to enter the dust box 230. The water vapor contacts the dust to adsorb the dust. The water vapor adsorbing the dust enters the dust box 237. Cold water is stored in the water storage tank 236. The hot water vapor contacts the cold inner wall of the dust box 237 and condenses into water. The beads fall into the dust box 237, and the dust and harmful gases are separated. The harmful gases are discharged through the exhaust pipe 240, and the harmful gases can be treated separately. The device can effectively fix the slab and also effectively utilize the heat emitted by the slab. The high temperature is used to evaporate water to form water vapor, and the water vapor adsorbs the dust. When cutting the slab, dust and harmful gases are prevented from flying around, which ensures the health of the on-site workers. At the same time, the evaporation of water can take away the heat on the slab, shortening the subsequent cooling time of the slab.

[0059] At the same time, the external water pump delivers clean water to the inside of the three-way pipe 315, and the clean water flows through the three-way pipe 315, the water supply main pipe 314 and the water supply branch pipe 316 in sequence to enter the evaporation box 215, and the second quantitative valve 317 is controlled to make the clean water drip into the evaporation tank 310 in a quantitative manner. The lower pressure plate 309 is made of metal iron. Under the action of heat conduction, the water in the evaporation tank 310 evaporates quickly, and the evaporated water vapor flows through the steam collecting branch pipe 318, the steam collecting main pipe 313 and the steam supply pipe 319 in sequence to enter the steam tank 222, thereby increasing the steam volume in the steam tank 222, so that dust can be better adsorbed during subsequent dust collection, thereby achieving a better dust removal effect;

[0060] After the slab is cut, the laminating press frame 213 is separated from the slab, the driving motor 306 and the transfer motor 323 are started, driving the moving roller 201 and the supporting roller 322 to rotate, and the cut slab is transferred. At the same time, the external circulation refrigerator is started, and the external circulation refrigerator delivers cold water to the circulating water pipe 304 and the circulating water tank 303. The cold water flows through the water channel 301 to cool the moving roller 201, thereby reducing the damage to the moving roller 201 caused by high temperature and extending the service life of the moving roller 201.

[0061] The water supply pipe 219, branch water pipe 220, steam branch pipe 223, drain pipe 224, collecting pipe 231, water supply branch pipe 316, steam collecting branch pipe 318 and steam supply pipe 319 in the device are all metal corrugated telescopic hoses, which are resistant to high temperatures and do not hinder the movement of the device.
