Description

Technical Field

[0001] The invention relates to the technical field of composite material processing, in particular to a high-temperature plastic flow control method and processing equipment for a nickel-steel composite plate during roll bonding. Background Art

[0002] Composite materials can generally be divided into layered metal composites, particle-reinforced composites and fiber-reinforced composites. Layered metal composites, as a type of composite material, refer to composite materials formed by metallurgical bonding at the interface using composite technology or multiple metals with different chemical and mechanical properties. They give full play to the special physical and chemical properties such as corrosion resistance, wear resistance, electrical properties, magnetic properties and mechanical properties such as strength, fracture toughness and impact toughness of the bimetallic materials, while significantly reducing material costs.

[0003] At present, most of the existing nickel-steel composite plates are prepared by the rolling composite method, that is, the composite method of welding different metal plates together by plastic deformation through the pressure of the rolling roller. During the rolling process, the coating material and the base material can be heated by the rolling roller as needed. However, during the high-temperature rolling process, there is a line contact between the plate and the hot roller, which causes the hot roller to stay for a period of time to complete the heating process, which increases the composite time consumption and reduces production efficiency. In addition, since the plate is only subjected to pressure when the distance between the two hot rollers is close, and the differences in the thermal expansion coefficient, thermal conductivity and mechanical properties of nickel and steel cause the interface between nickel and steel to produce a large interface friction. When the composite plate gradually moves away from the two hot rollers, residual stress will be generated at the interface between nickel and steel. This residual stress reduces the bonding degree of the two plates and the interface bonding quality of the composite plate cannot be guaranteed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a high-temperature plastic flow control method and processing equipment for the laminated rolling of a nickel-steel composite plate. Inert gas is used as the composite atmosphere as a whole to avoid the generation of a composite interface oxide layer. At the same time, an adjusting component capable of adjusting the contact area between the plate and the hot rolling mill is arranged at the front of the hot rolling mill, and the line contact between the plate and the hot rolling mill is adjusted to surface contact, thereby improving the heating efficiency and ensuring the composite production efficiency. In addition, a pressure holding component is arranged at the rear of the hot rolling mill to control the coordinated deformation and plastic flow of the nickel plate and the steel plate, thereby prompting the opposite metal to squeeze into the fresh surface formed by the interface rubbing through the plastic flow, thereby forming a mutually staggered interface, increasing the interface bonding strength, and at the same time, the internal stresses around the extrusion point can offset each other, so that the nickel plate and the steel plate will not produce excessive relative movement, thereby ensuring the interface bonding quality of the composite plate.

[0046] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0047] Example 1:

[0048] Refer to Figures 1 to 12 , the hot rolling high-temperature processing equipment for nickel-steel composite plates includes a rolling chamber 1. In the middle of the inner side of the rolling chamber 1, a hot rolling machine assembly 2 is fixedly arranged, and an adjusting component 3 is arranged on the side of the hot rolling machine assembly 2.

[0049] On the side wall of the rolling chamber 1 close to the adjusting component 3, feeding ports 11 are symmetrically opened. Inside each feeding port 11, cleaning strips 12 are symmetrically installed. On the side wall of the rolling chamber 1 close to the pressure maintaining component 4, a discharge port 13 is opened. An air inlet pipe 14 is installed on the top of the rolling chamber 1.

[0050] On the upper and lower side walls of the discharge port 13, cooling tables 131 are symmetrically installed. An air cavity is opened inside the cooling tables 131. The adjacent ends of the cooling tables 131 are in an arc surface structure and are linearly arranged with ventilation holes 132.

[0051] In the middle of the side wall of the hot rolling machine assembly 2 close to the adjusting component 3, a U-shaped plate 21 is fixedly installed. The opening of the U-shaped plate 21 faces the hot rolling machine assembly 2. On the side wall of the U-shaped plate 21 corresponding to the hot rolling machine assembly 2, support plates 22 are symmetrically connected. At the end of the support plate 22 far from the U-shaped plate 21, a positioning roller 23 is rotatably installed.

[0052] The adjusting component 3 includes an electric push rod 31. In the middle of the side wall of the rolling chamber 1 far from the pressure maintaining component 4, an electric push rod 31 is fixedly installed through a push rod base. The telescopic end of the electric push rod 31 is fixedly connected with an adjusting unit 32. The front and rear ends of the adjusting unit 32 are rotatably installed on the inner wall of the rolling chamber 1. Adjusting rods 33 are symmetrically installed on the adjusting unit 32. At the end of the adjusting rod 33 far from the adjusting unit 32, an adjusting roller 34 is rotatably installed.

[0053] The adjusting unit 32 includes a T-shaped rack 321. The telescopic end of the electric push rod 31 is fixedly connected with the T-shaped rack 321. On the upper and lower sides of the T-shaped rack 321, driven gears 322 are symmetrically meshed. The driven gears 322 are fixedly installed in the middle of the gear shafts 323. The ends of the gear shafts 323 are rotatably installed on the inner wall of the rolling chamber 1. At the end of the T-shaped rack 321 far from the electric push rod 31, a cross shaft 324 is fixedly connected. The cross shaft 324 penetrates to the inner side of the U-shaped plate 21 at the end far from the T-shaped rack 321. A buffer spring 325 is sleeved on the cross shaft 324 between the U-shaped plate 21 and the T-shaped rack 321.

[0054] In this embodiment, it should be noted that the maximum limit of the rotation of the upper and lower adjusting rollers 34 in the direction of moving away from each other is that the outer edge of the adjusting roller 34 and the loading port 11 are at the same horizontal height; in addition, the cleaning strip 12 provided in the loading port 11 can not only clean the upper and lower end surfaces of the nickel plate and the steel plate, but also play a sealing role, thereby preventing external air from entering the interior of the laminating chamber 1 and affecting the composite quality of the two plates.

[0055] In the specific operation, the nickel plate and the steel plate are first manually passed through the loading port 11, and then sequentially passed through the opposite side of the adjusting roller 34, the surface of the positioning roller 23, and the middle of the hot rolling mill assembly 2, and then passed out through the transition outlet 425 and the discharge port 13;

[0056] In the process of the nickel plate and the steel plate passing through the middle of the two hot rollers in the hot rolling mill assembly 2, the hot rolling mill assembly 2 can simultaneously perform high-temperature heating treatment on the nickel plate and the steel plate, and then complete the composite process through extrusion of the hot rolling mill assembly 2, and the adjustment component 3 can adjust the position of the adjustment roller 34, so as to control the contact area between the nickel plate and the steel plate and the hot rolling mill assembly 2 to adjust the heating rate. The specific adjustment process is: start the electric push rod 31, and drive the T-shaped rack 321 to move through the electric push rod 31. Under the action of the driven gear 322, the gear shaft 323 will drive the adjustment rod 33 and the adjustment roller 34 to rotate. When the upper and lower adjustment rollers 34 rotate in a direction close to each other, the upper and lower adjustment rollers 34 will drive the nickel plate and the steel plate to fit the surfaces of the two hot rollers in the hot rolling mill assembly 2, thereby increasing their contact area, thereby avoiding the time consumption of staying for heating, thereby improving the composite efficiency of the nickel plate and the steel plate.

[0057] Embodiment 2:

[0058] The technical solution is basically the same as that of the first embodiment, see Figure 1 ,to Figure 4 as well as Figures 9 to 12 The difference is that a pressure maintaining component 4 is installed on the side of the hot rolling mill assembly 2 away from the adjusting component 3.

[0059] The pressure-maintaining assembly 4 comprises a lining plate 41, and a lining plate 41 is symmetrically installed on one side of the hot rolling mill assembly 2 away from the adjusting assembly 3, and the end of the lining plate 41 is fixedly connected to the inner wall of the stacking and rolling chamber 1, and a limited sliding groove is symmetrically arranged on the opposite side wall of the lining plate 41, and a pressure-maintaining unit 42 is symmetrically installed in the limited sliding groove for sliding upward and downward movement, and a threaded rod 44 is symmetrically installed on the opposite side of the pressure-maintaining unit 42, and both ends of the threaded rod 44 extend to the outside of the stacking and rolling chamber 1 respectively, and one end of the threaded rod 44 is fixedly connected to a cam 48, and the other end of the threaded rod 44 is connected to a driving The driving unit 43 is fixedly mounted on the outer wall of the rolling chamber 1, a driving block 45 is screwed on the threaded rod 44, and a limiting rod 46 is symmetrically mounted on the driving block 45. The end of the limiting rod 46 away from the driving block 45 is slidably sleeved on the sliding shaft 47, and the sliding shaft 47 is symmetrically distributed on both sides of the driving block 45 and the end of the sliding shaft 47 is fixedly connected to the side wall of the rolling chamber 1. An air blowing unit 49 is fixedly mounted on the outer wall of the rolling chamber 1 on the side of the cam 48, and the air blowing unit 49 is communicated with the air cavity inside the cooling table 131.

[0060] The pressure-maintaining unit 42 includes a supporting spring 421, a horizontal plate 422 is slidably installed in the limiting slide groove through the supporting spring 421, pressure-maintaining rods 423 are evenly arranged on the opposite side walls of the horizontal plate 422, a connecting protrusion 424 is fixedly installed in the middle of the side wall opposite to the horizontal plate 422, and a transition outlet 425 is opened between the upper and lower limiting slide grooves.

[0061] The driving unit 43 includes a driving pulley 431, and the end of the threaded rod 44 located on the upper side away from the cam 48 is fixedly connected to the driving pulley 431, and the end of the threaded rod 44 located on the lower side away from the cam 48 is fixedly connected to the driven pulley 433, the driving pulley 431 and the driven pulley 433 are connected by an annular belt 432, and the end of the threaded rod 44 corresponding to the driving pulley 431 is connected to the output shaft of the reciprocating motor 434 through a coupling, and the reciprocating motor 434 is fixedly installed on the outer wall of the rolling chamber 1 through a machine base.

[0062] The inflation unit 49 includes an air cylinder 491, which is fixedly mounted on the outer wall of the rolling chamber 1 on the side of the cam 48, and a piston rod 492 is slidably mounted inside the air cylinder 491. A return spring 493 is sleeved between the piston rod 492 and the air cylinder 491, and the air outlet of the air cylinder 491 is connected to a one-way air outlet pipe 494, which is communicated with the air cavity inside the cooling table 131, and a one-way air inlet valve 495 is installed at the upper end of the air cylinder 491 near the one-way air outlet pipe 494.

[0063] In this embodiment, the one-way air intake valve 495 is connected to an external inert gas supply device.

[0064] During specific operation, when the composite plate passes through the transition outlet 425, the reciprocating motor 434 is started, and the reciprocating motor 434 drives the active pulley 431 to reciprocate. Under the action of the annular belt 432, the driven pulley 433 also reciprocates, thereby driving the upper and lower threaded rods 44 to reciprocate synchronously. During the reciprocating rotation of the threaded rod 44, the driving block 45 reciprocates back and forth along the threaded rod 44, and the driving block 45 squeezes the connecting protrusion 424 to drive the upper and lower transverse plates 422 to approach each other. At this time, the support spring 421 is compressed, and the pressure-maintaining rod 423 provided on the transverse plate 422 squeezes the opposite end faces of the composite plate. The squeezing force can control the coordinated deformation and plastic flow of the nickel plate and the steel plate, thereby prompting the opposite metal to squeeze into the fresh surface formed by the interface rubbing through plastic flow, thereby forming a mutually staggered interface, increasing the interface bonding strength, and at the same time, the internal stresses around the squeezing point can offset each other, so that the nickel plate and the steel plate will not produce excessive relative movement, thereby ensuring the interface bonding quality of the composite plate.

[0065] During the reciprocating rotation, the threaded rod 44 will also drive the cam 48 to reciprocate, and the cam 48 will intermittently squeeze the piston rod 492, thereby continuously driving the return spring 493 to compress and squeeze the inert gas inside the air cylinder 491 into the cooling platform 131 through the one-way air outlet pipe 494, and then spray it out through the air vent 132, thereby cooling the upper and lower end surfaces of the composite plate.

[0066] Finally, it is worth noting that in order to further improve the rolling quality of the nickel-steel composite plate, the external inert gas supply equipment and the air inlet pipe 14 can be connected before rolling, and inert gas can be introduced into the rolling chamber 1 through the external inert gas supply equipment, so that the composite process is carried out in an environment filled with inert gas. This can avoid the formation of an oxide layer on the bonding surface, thereby improving the interface bonding strength.

[0067] In addition, the present invention also provides a method for controlling plastic flow using the high-temperature processing equipment for rolling of the nickel-steel composite plate, which specifically includes the following steps:

[0068] S1, first manually pass the nickel plate and the steel plate through the loading port 11, then pass through the opposite side of the adjusting roller 34, the surface of the positioning roller 23 and the middle of the hot rolling mill assembly 2, and then pass out through the transition outlet 425 and the discharge port 13;

[0069] S2. In the process of the nickel plate and the steel plate passing through the middle of the two hot rollers in the hot rolling mill assembly 2, the hot rolling mill assembly 2 can simultaneously perform high-temperature heating treatment on the nickel plate and the steel plate, and then complete the composite process through extrusion of the hot rolling mill assembly 2, and the adjustment component 3 can adjust the position of the adjustment roller 34, so as to control the contact area between the nickel plate and the steel plate and the hot rolling mill assembly 2 to adjust the heating rate. The specific adjustment process is: start the electric push rod 31, and drive the T-shaped rack 321 to move through the electric push rod 31. Under the action of the driven gear 322, the gear shaft 323 will drive the adjustment rod 33 and the adjustment roller 34 to rotate. When the upper and lower adjustment rollers 34 rotate in a direction close to each other, the upper and lower adjustment rollers 34 will drive the nickel plate and the steel plate to fit the surfaces of the two hot rollers in the hot rolling mill assembly 2, thereby increasing their contact area, so as to avoid the time consumption of staying for heating, thereby improving the composite efficiency of the nickel plate and the steel plate;

[0070] S3. When the composite plate passes through the transition outlet 425, the reciprocating motor 434 is started, and the reciprocating motor 434 drives the driving pulley 431 to reciprocate. Under the action of the annular belt 432, the driven pulley 433 also reciprocates, thereby driving the upper and lower threaded rods 44 to reciprocate synchronously. During the reciprocating rotation of the threaded rod 44, the driving block 45 reciprocates back and forth along the threaded rod 44, and the driving block 45 squeezes the connecting protrusion 424 to drive the upper and lower transverse plates 422 to approach each other. At this time, the support spring 421 is compressed, and the pressure-maintaining rod 423 provided on the transverse plate 422 squeezes the opposite end faces of the composite plate. The squeezing force can control the coordinated deformation and plastic flow of the nickel plate and the steel plate, thereby prompting the opposite metal to squeeze into the fresh surface formed by the interface rubbing through plastic flow, thereby forming a mutually staggered interface, increasing the interface bonding strength, and at the same time, the internal stresses around the squeezing point can offset each other, so that the nickel plate and the steel plate will not produce excessive relative movement, thereby ensuring the interface bonding quality of the composite plate;

[0071] During the reciprocating rotation, the threaded rod 44 will also drive the cam 48 to reciprocate, and the cam 48 will intermittently squeeze the piston rod 492, thereby continuously driving the return spring 493 to compress and squeeze the inert gas inside the air cylinder 491 into the cooling platform 131 through the one-way air outlet pipe 494, and then spray it out through the air vent 132, thereby cooling the upper and lower end surfaces of the composite plate.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
