Referring to fig. 1, an embodiment of the present invention: a continuous production line for hot galvanizing of flat iron (multiple strips) comprises a feeding device, an annealing reduction furnace, a closed tension regulator, a zinc pot, an air knife part, a loading machine, a distributing guide mechanism, a cooling device, a distributing mechanism, a passivating drying device, a blanking device, a hydraulic transmission part and an electric control part, wherein the hot galvanizing of the flat iron takes an acid-washed steel strip as a base strip, the base strip is longitudinally cut into multiple flat irons by a longitudinal shearing machine set in the feeding device according to the width specification of the galvanized flat iron on the whole production line, then the flat irons enter the annealing reduction furnace for annealing reduction, the improved Sendzimir galvanizing process is adopted, the tension of the flat irons is regulated by the closed tension regulator, the length of the flat irons before entering the zinc pot is basically consistent, then the flat irons enter the zinc pot for galvanizing, all four sides of the flat irons after exiting the zinc pot are provided with zinc layers, and redundant zinc liquid on the surface of the flat irons is blown off by the air knife part after exiting the zinc pot, and then the flat irons Guiding and conveying the galvanized flat iron by a leveling machine, wherein the galvanized flat iron passes through a material distribution guide mechanism, a cooling device, a material distribution mechanism, a passivation device, a material distribution mechanism and a passivation drying device, and a guiding machine conveys the flat iron to a blanking leveling machine and finishes the operation of the guiding machine. And at the moment, a longitudinal shearing unit in the feeding device, a feeding leveling machine and a discharging leveling machine in the discharging device realize a linkage function, the galvanized flat iron is pulled to travel towards the discharging direction at a process speed, the transverse shearing machine is tracked by the discharging device in the traveling process of the galvanized flat iron at the traveling speed of the flat iron, when the length of the flat iron is tracked to reach the fixed length of the finished flat iron, the transverse shearing machine is controlled by a computer to perform a transverse shearing process, the galvanized flat iron after transverse shearing falls on a conveying roller way, and is conveyed forwards to a packing position by the conveying roller way after reaching one package, and the galvanized flat iron is packed and warehoused. The tracking transverse shearing machine which finishes the shearing process quickly returns to the original point, continues to track the flat iron which moves forwards, and repeatedly tracks and shears. The continuous production characteristic of the whole production line is realized.
Further, the feeding equipment comprises an uncoiler, a feeding trolley, a leveling and drawing machine, a cross shearing machine, a vertical roll guiding machine, a welding workbench, a No. 1 clamping and conveying machine, a storage loop, a No. 2 clamping and conveying machine, a double-station longitudinal shearing machine set, a leveling machine, a washing mechanism, a tension detection machine, a drawing machine, a feeding hydraulic station and a feeding end electric control part. And reasonably arranging the mechanical equipment according to the process requirements. Various machines play the role of the feeding device, and ensure the technical functions of the feeding device on the whole production line: namely, the continuous production of the flat iron galvanization, the online strip division of the flat iron base band, the online galvanization, the online collection and packaging, the treatment measures when the flat iron is broken in the furnace zone and the like are met.
Further, the improved sendzimir hot galvanizing method is adopted to carry out the continuous production of the hot galvanizing of the flat iron.
The process has the characteristics that the combustion temperature of an annealing area is high, the surface oxidation of the strip steel is small, and a reduction section of a reduction area can be lengthened on the premise that the site is not limited so as to achieve a good reduction effect. The first surface of the galvanized flat iron produced in the way is high in smoothness, the second surface of the galvanized flat iron is free from plating leakage, and the third surface of the galvanized flat iron is high in yield.
Further, the closed tension regulator regulates the tension of the flat iron, so that the flat iron enters the zinc pot for galvanizing after the length of the flat iron before entering the zinc pot is basically consistent, and the deformation of the flat iron in the furnace area caused by heat radiation is shaped in the process.
Furthermore, the submerged roller part of the zinc pot is improved, and blocking edges are manufactured at two sides of the roller body of the submerged roller. The flat iron entering the zinc pot is prevented from separating from the roller body, and the guiding function of the flat iron entering and exiting the zinc pot is achieved.
Furthermore, the machine is composed of a main frame part, a material distributor, a clamping and conveying machine, a material stop mechanism, a material pressing mechanism and a large guide mechanism. Each flat iron is isolated by a material distributor before the liquid zinc on the surface of the flat iron is solidified after the flat iron is discharged from a zinc pot, then the flat iron enters a large guide mechanism, the direction of the flat iron discharged from the zinc pot is the vertical direction, the traveling direction of the flat iron needs to be changed by the large guide mechanism, the traveling direction is changed from the vertical direction to the horizontal direction, the temperature is about more than 350 ℃, an operator cannot approach the flat iron, the moving direction of the flat iron needs to be changed by a material stop mechanism and a material pressing mechanism, and all mechanical actions are controlled by hydraulic pressure. Because the temperature of the flat iron out of the zinc pot is very high, the temperature of the large guide roller mechanism is also very high, and because the production line is continuous production, the large guide roller must be cooled, otherwise, the roll surface of the large guide roller can be subjected to zinc dipping after long-time continuous operation, so that the surface of the flat iron is rough. Aiming at the phenomenon, the cooling water tank is designed at the lower part of the roller body of the large guide roller, and the circulating water is used for cooling, so that the lower part of the roller body of the large guide roller is always soaked in water, and the phenomenon of zinc dipping is effectively solved. The pinch machine is used for providing walking power after the flat iron just comes out of the zinc pot when the flat iron is produced for the first time or is produced again after the pinch machine is stopped.
Further, under the action of the material distribution guide mechanism, the movement direction of the galvanized flat iron is changed after the galvanized flat iron passes through the machine, and at the moment, the phenomenon of overlapping and disordering occurs among a plurality of flat irons, so that each flat iron is required to be separated by the material distribution mechanism through the material distribution disc. Making it advance in order.
The condition that all can appear warping at the galvanized band iron behind water cooling plant and passivating device because of expend with heat and contract with cold's reason, also need at this moment feed mechanism to separate every band iron through the branch charging tray. Making it advance in order.
Further, the passivation drying device is composed of a drying box, a draught fan and a draught fan pipeline. The waste gas in the annealing reduction furnace is led to the drying box for secondary utilization through the draught fan, and the passivating liquid on the surface of the passivated galvanized flat iron is dried, so that the phenomenon that the surface of the flat iron is oxidized due to the fact that the storage environment is moist because the storage time of the surface of the flat iron is too long is avoided.
Further, the blanking equipment consists of a leveler, a tracking cross shear and a blanking platform. The leveler determines the process speed of the whole production line, the speeds of other devices are automatically adjusted by a computer in coordination with the process speed of the leveler, and the leveler is matched with the feeding leveler to control the tension in a furnace area so as to provide power for the forward movement of the galvanized flat iron and level the galvanized flat iron.
Further, when the tracking cross shearing machine finishes the transverse shearing process, the tracking cross shearing needs to track the process speed of the flat iron first, and the transverse shearing process is started when the tracking speed of the tracking cross shearing is consistent with the process speed of the flat iron and reaches the fixed length of the galvanized flat iron product, so that a problem occurs, and the process speeds of the flat irons with different thickness specifications are different. The thinner the thickness of the flat iron, the faster the process speed, and the thicker the thickness of the flat iron, the slower the process speed. That is to say, the process speed of the flat iron with different thickness is different in the production process, so the tracking time and the tracking distance of the tracking cross shear are different, that is to say, the tracking starting point of the tracking cross shear is consistent with the falling point of the flat iron but not the same. And the production process requires that the drop points of the flat iron are consistent. Therefore, a large push plate is arranged on a moving body of the tracking cross shear equipment, the position of the large push plate is arranged below a lower knife edge of the cross shear, the position of the large push plate can be adjusted front and back, different positions are adjusted according to different speeds of the galvanized flat iron, the galvanized flat iron with different drop points is pushed to a uniform drop point in the tracking process of the moving body of the tracking cross shear through the different positions of the large push plate, and then the small push plate pushes the dropped galvanized flat iron uniformly.
The length of each group of the blanking platforms is 6 meters, each group of the blanking platforms consists of 6 groups of driving rollers, 5 groups of driven rollers and two groups of lifting mechanisms, and the height of each blanking platform can be adjusted in a lifting mode. The three groups of blanking platforms can independently control the transmission of the driving roller and can also control the transmission of the driving roller simultaneously, and each group of galvanized flat iron products has the requirement of blanking. The tail end of the first group of blanking platforms is provided with a group of sizing baffles which are matched with a small push plate mechanism of a tracking cross shearing machine to finish the finished product packaging alignment work of the galvanized flat iron product. After one package is achieved in the production of the galvanized flat iron, the galvanized flat iron is conveyed to a second group or a third group of blanking platforms by a conveying roller way to be manually beaten, packaged and warehoused. The first blanking platform continues to collect the next pack of galvanized flat iron, and the whole process production process has no link of stopping. Continuous production is realized.
Furthermore, the hydraulic part provides power for the hydraulic action of the whole production line, the electric control part controls the power source of the whole production line, the speed regulation function is provided according to the property of the power source, and the single-action control and the linkage control are adopted to realize two functions according to the production requirement. The linkage function is to input the program into the PLC according to the process function required by the whole production line, then the PLC controls the process function of each stage of the production line, and the whole production process is completed through the integral cooperation of the machine, the electricity and the liquid.
Example 2
A continuous production line for hot galvanizing of flat iron (multiple strips):
the closed tension adjusting machine is arranged at the position before the flat iron enters the zinc pot, and has the following functions: 1. adjusting the tension of the flat irons in the furnace area to ensure that a plurality of flat irons keep moving forwards synchronously; 2. the deformation of the flat iron in the furnace area caused by thermal radiation is shaped, so that the length of the flat iron entering the zinc pot is consistent.
According to the flat irons with different specifications, the furnace zone temperature of each section of the open flame section, the radiation reduction section, the slow cooling section, the fast cooling section and the like in the annealing reduction furnace is controlled, so that the thermal deformation of the flat iron in the furnace zone is minimized after the annealing reduction process function is completed.
Example 3
A continuous production line for hot galvanizing of flat iron (multiple strips):
the machine consists of a main frame part, a material distributor, a clamping and conveying machine, a material stop mechanism, a material pressing mechanism and a large guide mechanism. Each flat iron is isolated by a material distributor before the liquid zinc on the surface of the flat iron is solidified after the flat iron is discharged from a zinc pot, then the flat iron enters a large guide mechanism, the direction of the flat iron discharged from the zinc pot is the vertical direction, the traveling direction of the flat iron needs to be changed by the large guide mechanism, the traveling direction is changed from the vertical direction to the horizontal direction, the temperature is about more than 350 ℃, an operator cannot approach the flat iron, the moving direction of the flat iron needs to be changed by a material stop mechanism and a material pressing mechanism, and all mechanical actions are controlled by hydraulic pressure. Because the temperature of the flat iron out of the zinc pot is very high, the temperature of the large guide roller mechanism is also very high, and because the production line is continuous production, the large guide roller must be cooled, otherwise, the roll surface of the large guide roller can be subjected to zinc dipping after long-time continuous operation, so that the surface of the flat iron is rough. Aiming at the phenomenon, the cooling water tank is designed at the lower part of the roller body of the large guide roller, and the circulating water is used for cooling, so that the lower part of the roller body of the large guide roller is always soaked in water, and the phenomenon of zinc dipping is effectively solved. The pinch machine is used for providing walking power after the flat iron just comes out of the zinc pot when the flat iron is produced for the first time or is produced again after the pinch machine is stopped.
Example 4
A continuous production line for hot galvanizing of flat iron (multiple strips):
the temperature of the flat iron after being discharged from the zinc pot is 420-480 ℃ in the production process, the flat iron enters a cooling process and a passivation process after being discharged from the zinc pot through an aging treatment process, a circulating water cooling process is adopted in the cooling process, the cooling effect of the cooling process can meet the requirement, but the deformation of expansion caused by heat and contraction caused by cold is large, and the flat iron can be ensured to be arranged orderly in the forward process only by moving forward in a horizontal state as much as possible. Therefore, the circulating water cooling water tank, namely the 'primary-secondary tank', is used for cooling the flat iron, so that the flat iron is always soaked in water in the cooling section and moves forward in a horizontal state.
The galvanized flat iron circulating water cooling water tank ' primary-secondary tank ' is a combined body formed by combining ' secondary tank ' and ' primary tank
The outside water pool sprays water into the sub-tank from top to bottom in a mode of arranging spray pipes through a water pump until the water level line in the sub-tank exceeds the elevation of a traveling route of the galvanized flat iron in the sub-tank and is lower than the overflow water level line, and the standard is realized by adjusting an overflow water level stop valve and the gap of the flat iron in water blocking plates passing through the inlet and the outlet of the sub-tank. The cooling water overflowed from the sub-tank flows into the main tank, and is pumped back to the external cooling water tank by a water pump for circulation cooling repeatedly. If the installation position of the primary and secondary tanks is higher than that of the external cooling water tank, the cooling water in the primary tank can automatically flow back to the external cooling water tank.
The air knives are arranged at the inlet and outlet positions in the female groove, the fan transmits air to the air knives, and the air knives blow the air uniformly to the flat iron to prevent cooling water from flowing out of the female groove.
Example 5
A continuous production line for hot galvanizing of flat iron (multiple strips):
the principle of the galvanized flat iron passivation device-passivation primary and secondary grooves is the same as that of the embodiment 4.
Example 6
A continuous production line for hot galvanizing of flat iron (multiple strips):
the material distributing mechanism consists of a material distributing shaft, a material distributing disc and a hydraulic lifting mechanism, and when the material is distributed, the material distributing disc is lifted by the hydraulic lifting mechanism to separate the flat irons.
Example 7
A continuous production line for hot galvanizing of flat iron (multiple strips):
the tracking cross shear is responsible for shearing the finished product of the fixed-length galvanized flat iron, when the transverse shearing process is finished, the tracking cross shear needs to track the process speed of the galvanized flat iron firstly, the transverse shearing process is started when the tracking speed of the tracking cross shear is consistent with the process speed of the flat iron, and when the process is finished, the tracking cross shear is always in a moving forward state. This presents a problem in that the speed of the process varies for different gauge sizes of sheet iron. The thinner the thickness of the flat iron, the faster the process speed, and the thicker the thickness of the flat iron, the slower the process speed. That is to say, the process speed of the flat iron with different thickness is different in the production process, so the tracking time and the tracking distance of the tracking cross shear are different, that is to say, the tracking starting point of the tracking cross shear is consistent with the falling point of the flat iron but not the same. And the production process requires that the drop points of the flat iron are consistent. Therefore, a large push plate is arranged on a moving body of the tracking cross shear equipment, the position of the large push plate is arranged below a lower knife edge of the cross shear, the position of the large push plate can be adjusted front and back, different positions are adjusted according to different speeds of the galvanized flat iron, the galvanized flat iron with different drop points is pushed to a uniform drop point in the tracking process of the moving body of the tracking cross shear through the different positions of the large push plate, and then the small push plate pushes the dropped galvanized flat iron uniformly.
The working principle of the whole production line is as follows: the flat iron is produced by using acid washed or water washed steel belt as base belt, longitudinally cutting the base belt by a longitudinal shearing machine set according to the width specification of galvanized flat iron on the whole production line, annealing and reducing the base belt in an annealing reduction furnace, galvanizing the base belt in a galvanizing pot, transversely shearing the galvanized flat iron with a fixed length by a tracking transverse shear under the control of a computer after passing through a cooling and passivating drying device, advancing the galvanized flat iron at the process speed without stopping, falling the transversely sheared flat iron on a conveying roller, conveying the galvanized flat iron to a packing position by the conveying roller after reaching one package, and packing and warehousing.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
