Description

Technical Field

[0001] The invention belongs to the technical field of hot-rolled steel plate surface treatment, and particularly relates to a process for improving the wrinkling defects on the surface of titanium and titanium alloy hot-rolled coils. Background Art

[0002] In the production process of hot-rolled titanium and titanium alloy coils, surface wrinkling defects have always been a key problem that has plagued the industry; in the rolling process, improper temperature control, inability to accurately match the rolling speed, and unbalanced distribution of rolling force in various parts of the plate will all lead to uncoordinated deformation of hot-rolled titanium and titanium alloy plates and wrinkling;

[0003] Therefore, the straightening process plays a key role in eliminating the wrinkle defects on the surface of titanium and titanium alloy hot-rolled plates and improving the flatness of the plates. However, in traditional straightening equipment, there is a problem that the straightening force cannot be accurately controlled; if the force applied during straightening is too large, it exceeds the elastic limit of the titanium and titanium alloy hot-rolled plates, causing excessive plastic deformation of the titanium and titanium alloy hot-rolled plates; when the straightening force is withdrawn, the titanium and titanium alloy hot-rolled plates will undergo reverse deformation due to the interaction of elastic recovery and plastic deformation; on the contrary, if the straightening force is too small, the titanium and titanium alloy hot-rolled plates cannot be effectively straightened;

The force applied during straightening is too large, exceeding the elastic limit of the steel plate, causing excessive plastic deformation of the steel plate; when the straightening force is withdrawn, the steel plate will be reversely deformed due to the interaction of elastic recovery and plastic deformation; on the contrary, if the straightening force is too small, the steel plate cannot be effectively straightened;

Summary of the invention

[0006] The object of the present invention is to overcome the deficiencies in the prior art and provide a process for improving the surface wrinkling defects of hot-rolled titanium and titanium alloy plates. Through the leveling seat in the straightening mechanism, the hot-rolled titanium and titanium alloy plates are limited during the extrusion and straightening by the leveling rolls, preventing the reverse deformation of the hot-rolled titanium and titanium alloy plates caused by excessive downward pressure of the leveling rolls. Through the spraying and brushing mechanism, not only the rapid cooling of the hot-rolled titanium and titanium alloy plates after annealing is achieved, but also the efficient cleaning of the oxide scale on the surface of the hot-rolled titanium and titanium alloy plates is realized. Through the drying mechanism, the efficient dehydration and drying of the surface of the hot-rolled titanium and titanium alloy plates are realized.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A process for improving the surface wrinkling defects of hot-rolled titanium and titanium alloy plates, the process steps are as follows:

[0009] 1) Annealing: The hot-rolled titanium and titanium alloy plates are annealed through an annealing device, the solution heat treatment temperature is 800°C ± 5°C, and the annealing process speed is 6 m / min - 8 m / min;

[0010] 2) Post-annealing treatment: The re-treatment of the surface wrinkling defects of the coil is completed through a post-annealing treatment device;

[0011] a) Deviation correction: Motor II starts, drives the bidirectional lead screw I to rotate, so that the two sets of deviation correction plates slide mirror-symmetrically along the sliding rod I and contact both sides of the hot-rolled titanium and titanium alloy plates to correct the deviation of the hot-rolled titanium and titanium alloy plates. The lateral thrust applied by the deviation correction plates to the hot-rolled titanium and titanium alloy plates is 200 - 300 N;

[0012] b) Cooling: When the hot-rolled titanium and titanium alloy plates enter the spraying area of the treatment tank along with the transmission rolls, water flows in from the water inlet of the connecting pipe I, enters the fixed pipe through the sleeve, and then reaches the moving pipe through the hose I. Motor III starts, drives the bidirectional lead screw II to rotate through the belt, so that the moving frame I slides along the sliding rod II in the sliding groove I, and then drives the moving pipes on both sides of the transmission rolls in the spraying area of the treatment tank to move up and down mirror-symmetrically, so that the high-pressure nozzles can approach the hot-rolled titanium and titanium alloy plates to cool and wash the surface of the hot-rolled titanium and titanium alloy plates. The water outlet pressure of the high-pressure nozzles is 1.5 - 2 MPa, so that the surface temperature of the hot-rolled titanium and titanium alloy plates quickly drops below 150°C;

[0013] c) Removal of scale: Motor Ⅳ drives the rotation of rotating rod Ⅰ, and rotating rod Ⅰ drives the swing of connecting rod Ⅰ, causing the high-pressure nozzle to rotate at the hemispherical water outlet end of the moving pipe, effectively flushing the scale on the surface of the titanium and titanium alloy hot continuous rolling plate; while spraying, several groups of electric push rods simultaneously push the brush plate closer to the titanium and titanium alloy hot continuous rolling plate to brush the remaining scale on the surface of the titanium and titanium alloy hot continuous rolling plate. Motor Ⅴ drives the bevel gear on the telescopic rod, driving the belt pulleys at both ends of the brush plate to rotate at a speed of 200 revolutions per minute. While the brush heads on one side of the belt brush the titanium and titanium alloy hot continuous rolling plate, the scale accumulated on one side of the brush plate is brushed to the bottom of the spray area of the treatment tank;

[0014] d) Removal of surface moisture: After the titanium and titanium alloy hot continuous rolling plate enters the drying area of the treatment tank, Motor Ⅵ drives the worm, driving the two rotating shafts to rotate mirror-symmetrically. The connecting rods Ⅱ at both ends of the rotating shafts drive the moving frame Ⅱ to slide in the sliding groove Ⅲ of the fixed rod, making the air jet head close to the titanium and titanium alloy hot continuous rolling plate while accurately adjusting the extrusion force of the squeezing roller on the titanium and titanium alloy hot continuous rolling plate. The linear pressure of the squeezing roller on the titanium and titanium alloy hot continuous rolling plate is 1.2 - 1.5 kN / m; Motor Ⅶ drives the squeezing roller to rotate, and most of the surface moisture of the titanium and titanium alloy hot continuous rolling plate is removed by frictional extrusion on the roller surface, and the removal rate can reach 85%; at the same time, the hot air generated by the hair dryer is shunted to each hose Ⅱ through the connecting pipe Ⅱ and finally sprayed out from the air jet head at the bottom of the T-shaped frame. Motor Ⅷ drives the rotation of rotating rod Ⅱ, driving the T-shaped frame to perform a fan-shaped sweep through the sliding groove Ⅴ, so that the hot air covers the surface of the titanium and titanium alloy hot continuous rolling plate at multiple angles, quickly removing the surface moisture of the titanium and titanium alloy hot continuous rolling plate;

[0015] e) Straightening: The titanium and titanium alloy hot continuous rolling plate is conveyed from the drying area of the treatment tank to the support frame Ⅱ by the conveying roller. Several groups of hydraulic cylinders simultaneously push the sliding plate, and the thrust of the hydraulic cylinder is 1.5 - 2 kN, causing the flattening roller to press down and cooperate with the conveying roller to flatten and straighten the titanium and titanium alloy hot continuous rolling plate. The flattening seat limits the titanium and titanium alloy hot continuous rolling plate; Motor Ⅹ drives the rotation of the bidirectional lead screw Ⅲ, causing the two limit plates to move mirror-symmetrically. The telescopic plate performs deviation correction and limitation on the titanium and titanium alloy hot continuous rolling plate during the straightening of the titanium and titanium alloy hot continuous rolling plate; Motor Ⅺ drives the reciprocating lead screw, causing the scraper to reciprocate at a speed of 0.3 - 0.5 m per minute to clean the impurities attached to the surfaces of the flattening roller and the conveying roller, ensuring the flatness of the surfaces of the flattening roller and the conveying roller; The lubricant in the water cylinder is applied to the surfaces of the flattening roller and the conveying roller through the sponge sleeve, and the thickness of the lubricant application is 0.01 - 0.03 mm, reducing the friction force of the conveying roller and the flattening roller on the titanium and titanium alloy hot continuous rolling plate during straightening, and reducing the friction coefficient from 0.12 to below 0.04.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1) Titanium and titanium alloy hot-rolled plates are transported from the drying area of ​​the processing box to the support frame II by the transmission roller. Several hydraulic cylinders push the sliding plate at the same time to press the leveling roller downward, and cooperate with the transmission roller to flatten and straighten the titanium and titanium alloy hot-rolled plates. The leveling seat limits the titanium and titanium alloy hot-rolled plates to prevent the leveling roller from pressing too hard and causing the titanium and titanium alloy hot-rolled plates to deform in the opposite direction; the motor X drives the bidirectional screw III to rotate, so that the two sets of limit plates move in a mirror image. The telescopic plate corrects and limits the titanium and titanium alloy hot-rolled plates when they are straightened, which can effectively reduce the deviation and shaking of the titanium and titanium alloy hot-rolled plates during the transmission and straightening process, improve the straightening accuracy of the titanium and titanium alloy hot-rolled plates, and ensure the stability and reliability of the straightening effect;

[0029] 2) The motor Ⅺ drives the reciprocating lead screw to make the scraper move reciprocally, cleaning the impurities adhering to the surfaces of the leveling roller and the transmission roller, ensuring the flatness of the surfaces of the leveling roller and the transmission roller, and preventing the impurities on the surfaces of the leveling roller and the transmission roller from scratching the surface of the hot continuous rolling titanium and titanium alloy plate during straightening; the lubricant in the water cylinder is applied to the surfaces of the leveling roller and the transmission roller through the sponge sleeve, reducing the friction between the transmission roller and the leveling roller and the hot continuous rolling titanium and titanium alloy plate during straightening, and significantly reducing the risk of scratching the surface of the hot continuous rolling titanium and titanium alloy plate;

[0030] 3) The motor Ⅲ starts, drives the bidirectional lead screw Ⅱ to rotate through the belt, makes the moving frame Ⅰ slide along the sliding rod Ⅱ in the sliding groove Ⅰ, and then drives the moving pipes on the upper and lower sides of the transmission roller in the spraying area of the processing box to move up and down mirror-symmetrically, so that the high-pressure nozzles can approach the hot continuous rolling titanium and titanium alloy plate and wash the surface of the hot continuous rolling titanium and titanium alloy plate; at the same time, the motor Ⅳ drives the rotating rod Ⅰ to rotate, and the rotating rod Ⅰ drives the connecting rod Ⅰ to swing, making the high-pressure nozzles rotate at the hemispherical water outlet ends of the moving pipes, realizing multi-angle spraying and effectively scouring the scale on the surface of the hot continuous rolling titanium and titanium alloy plate; during spraying, several groups of electric push rods simultaneously push the brush plate close to the hot continuous rolling titanium and titanium alloy plate to brush the remaining scale on the surface of the hot continuous rolling titanium and titanium alloy plate. The motor Ⅴ drives the bevel gear on the telescopic rod to drive the belt pulleys at both ends of the brush plate to rotate. While the brush heads on one side of the belt brush the hot continuous rolling titanium and titanium alloy plate, the scale gathered on one side of the brush plate is brushed to the bottom of the spraying area of the processing box; it not only realizes the rapid cooling of the hot continuous rolling titanium and titanium alloy plate after annealing, but also realizes the efficient cleaning of the scale on the surface of the hot continuous rolling titanium and titanium alloy plate, preventing uneven stress during straightening due to the remaining scale on the surface of the hot continuous rolling titanium and titanium alloy plate during the subsequent straightening by the straightening mechanism, which affects the straightening quality of the hot continuous rolling titanium and titanium alloy plate;

[0031] 4) The motor Ⅵ drives the worm, driving the two groups of rotating shafts to rotate mirror-symmetrically. The connecting rods Ⅱ at both ends of the rotating shafts drive the moving frame Ⅱ to slide in the sliding groove Ⅲ of the fixed rod, making the air jet heads approach the hot continuous rolling titanium and titanium alloy plate while precisely adjusting the extrusion force of the squeezing roller on the hot continuous rolling titanium and titanium alloy plate; the motor Ⅶ drives the squeezing roller to rotate, and most of the water on the surface of the hot continuous rolling titanium and titanium alloy plate is removed by frictional extrusion through the roller surface; at the same time, the hot air generated by the hair dryer is shunted to each hose Ⅱ through the connecting pipe Ⅱ and finally ejected from the air jet heads at the bottom of the T-shaped frame. The motor Ⅷ drives the rotating rod Ⅱ to rotate, driving the T-shaped frame to perform a fan-shaped sweep through the sliding groove Ⅴ, so that the hot air covers the surface of the hot continuous rolling titanium and titanium alloy plate at multiple angles, realizing the efficient dehydration and drying of the surface of the hot continuous rolling titanium and titanium alloy plate.

The linear pressure of the squeeze roller on the titanium and titanium alloy hot-rolled plates is 1.2-1.5kN / m; the motor VII drives the squeeze roller to rotate, and most of the moisture on the surface of the titanium and titanium alloy hot-rolled plates is removed by friction and squeezing of the roller surface, and the removal rate can reach 85%; at the same time, the hot air generated by the hair dryer is diverted to each hose Ⅱ through the connecting pipe Ⅱ, and finally sprayed out from the nozzle at the bottom of the T-frame, and the motor Ⅷ drives the rotating rod Ⅱ to rotate, and drives the T-frame to sweep in a fan shape through the sliding groove Ⅴ, so that the hot air covers the surface of the titanium and titanium alloy hot-rolled plates at multiple angles, and quickly removes the moisture on the surface of the titanium and titanium alloy hot-rolled plates; Straightening: Titanium and titanium alloy hot-rolled plates are transported from the drying area of ​​the processing box to the support frame II by the transmission roller. Several hydraulic cylinders push the sliding plate at the same time. The thrust of the hydraulic cylinder is 1.5-2kN, which presses the leveling roller downward and cooperates with the transmission roller to flatten and straighten the titanium and titanium alloy hot-rolled plates. The leveling seat limits the titanium and titanium alloy hot-rolled plates; the motor Ⅹ drives the bidirectional screw III to rotate, so that the two sets of limit plates move in a mirror image. The telescopic plate corrects and limits the titanium and titanium alloy hot-rolled plates when the titanium and titanium alloy hot-rolled plates are straightened; the motor Ⅺ drives the reciprocating screw to make the scraper reciprocate at a speed of 0.3-0.5m per minute to clean the impurities attached to the surface of the leveling roller and the transmission roller to ensure the flatness of the surface of the leveling roller and the transmission roller; the lubricant in the water cylinder is applied to the surface of the leveling roller and the transmission roller through the sponge sleeve. The thickness of the lubricant is 0.01- 0.03mm, reducing the friction of the transmission roller and leveling roller on titanium and titanium alloy hot-rolled plates during straightening, and reducing the friction coefficient from 0.12 to below 0.
