Description

Technical Field

[0001] This utility model relates to the field of bar and wire production technology, and in particular to a bar and wire production system. Background Technology

[0002] The bar and wire rod production line arranges the rolling mill and continuous casting workshop adjacent to each other, allowing for flexible production processes. Billets can be heated to the required standard in a reheating furnace before being fed into the production line for rolling, or high-temperature continuously cast billets from the continuous casting plant can be directly fed into the production line for rolling. Both production lines primarily use direct rolling. When the production of the rolling mill and continuous casting workshop is not matched, cold billets coming off the line are processed using the reheating furnace. Currently, the two bar and wire rod production lines share one reheating furnace, located on one side of the bar production line. A billet transverse transfer device is installed behind the furnace. If the wire rod production line requires billets from the reheating furnace, the heated billets can be transported to the wire rod production line via the billet transverse transfer device.

[0003] However, given the large demand for wire rod and the relatively small demand for bar rod, the long conveying path of the billet from the heating furnace on one side of the bar rod production line to the wire rod rolling mill affects wire rod production efficiency. Furthermore, since wire rod products contain a certain proportion of high-end drawing steel, which requires heating in a heating furnace, existing bar and wire rod production lines cannot meet production demands. Therefore, a new bar and wire rod production system is urgently needed to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a bar and wire rod production system, including a bar production line, a wire rod production line, and a first heating furnace. The bar production line is connected to the feeding end via a bar straight rolling mill roller table, and the wire rod production line is connected to the feeding end via a wire straight rolling mill roller table. The first heating furnace is located on the side of the bar straight rolling mill roller table away from the wire straight rolling mill roller table, and its discharge end is connected to the bar straight rolling mill roller table. The system also includes a second heating furnace, which is located between the bar straight rolling mill roller table and the wire straight rolling mill roller table, and its discharge end is connected to the wire straight rolling mill roller table. A billet transverse transfer mechanism for bidirectional transfer of billets between the bar straight rolling mill roller table and the wire straight rolling mill roller table is also provided. Both the first heating furnace and the second heating furnace are located on the side of the billet transverse transfer mechanism closer to the feeding end.

[0005] Furthermore, the feed roller conveyor of the second heating furnace is connected to the bar rolling roller conveyor, and a steel-separating mechanism is provided at the connection point. The steel-separating mechanism is connected to a steel-separating drive unit for switching between a first working position and a second working position. In the first working position, the channel between the bar production line and the feeding end is connected, and in the second working position, the channel between the second heating furnace and the feeding end is connected.

[0006] Furthermore, the steel-splitting mechanism includes a fixed base and a steel-splitting component. One end of the steel-splitting component is sleeved on the fixed base and can rotate around the fixed base. The steel-splitting drive unit is hinged to the steel-splitting component to drive the steel-splitting component to switch between a first working position and a second working position.

[0007] Furthermore, the discharge end of the second heating furnace is provided with a discharge roller conveyor, which includes a plurality of discharge rollers arranged at intervals. At the junction of the second heating furnace and the wire rod straight rolling mill, the plurality of discharge rollers and the wire rod rollers of the wire rod straight rolling mill are alternately arranged along the billet running direction.

[0008] Furthermore, the feeding end of the second heating furnace is provided with a cold billet feeding platform, which is connected to the furnace inlet roller conveyor of the second heating furnace.

[0009] Furthermore, the billet transverse transfer mechanism includes several billet transfer brackets, each of which is arranged at intervals perpendicular to the billet transfer direction. Each billet transfer bracket has a groove, and each groove contains a transmission chain. Each transmission chain has a billet transfer block and a chain tensioning device. One side of one of the billet transfer brackets is provided with a billet transfer drive unit for driving the rotation of each transmission chain.

[0010] Furthermore, the billet transverse movement mechanism also includes several billet platforms, with each billet platform and each billet moving support arranged alternately, and the elevation of the billet platform is not lower than the elevation of the billet moving support.

[0011] Furthermore, the discharge end of the first heating furnace is equipped with a first transfer device for transferring the billet from the first heating furnace to the bar straight rolling mill or the billet transverse transfer mechanism, and for transferring the billet from the billet transverse transfer mechanism to the bar straight rolling mill.

[0012] Furthermore, the billet transverse transfer mechanism is provided with a second transfer device at one end near the wire rod straight rolling mill for transferring the billet between the wire rod straight rolling mill and the billet transverse transfer mechanism.

[0013] Furthermore, both sides of the feeding end are provided with cold billet storage areas for storing cold billets, and the cold billet storage areas are connected to the feeding end through cold billet roller conveyors.

Additionally, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] As per the instruction manual Figure 1As shown, this utility model provides a bar and wire rod production system, including a bar production line 4, a wire rod production line 5, and a first heating furnace 6. The bar production line 4 is connected to the feeding end via a bar straight rolling mill 2, and the wire rod production line 5 is connected to the feeding end via a wire straight rolling mill 3. The first heating furnace 6 is located on the side of the bar straight rolling mill 2 away from the wire straight rolling mill 3, and its discharge end is connected to the bar straight rolling mill 2. The system also includes a second heating furnace 7, which is located between the bar straight rolling mill 2 and the wire straight rolling mill 3, and its discharge end is connected to the wire straight rolling mill 3. A billet transverse transfer mechanism 8 for bidirectional transfer of billets between the bar straight rolling mill 2 and the wire straight rolling mill 3 is also provided between them. Both the first heating furnace 6 and the second heating furnace 7 are located on the side of the billet transverse transfer mechanism 8 closer to the feeding end.

[0027] Specifically, the feeding end refers to the equipment that can provide hot steel billets. In this embodiment, the feeding end refers to the continuous casting production line 1, which is used to provide hot steel billets. When the continuous casting capacity matches the rolling capacity, the hot steel billets after continuous casting by the continuous casting production line 1 are sent to the bar production line 4 by the bar straight rolling roller table 2 for rolling into bars, or sent to the wire rod production line 5 by the wire rod straight rolling roller table 3 for rolling into wire rods. When the continuous casting capacity is greater than the rolling capacity, the remaining steel billets are cooled by the continuous casting turning cooling bed 11 at the discharge end of the continuous casting production line 1 and then stored offline. Both sides of the continuous casting production line 1 are provided with cold billet storage areas for storing cold billets. The cold billet storage areas are connected to the continuous casting turning cooling bed 11 through cold billet roller tables 12. The cold billets in the cold billet storage areas can be used by the heating furnace. The two cold billet roller tables 12 are used for bar cold billet feeding and wire rod cold billet feeding, respectively. When the steel rolling capacity is greater than the continuous casting capacity, at least one heating furnace can be turned on. The heating furnace heats the cold billet to the set temperature and then conveys it to the bar production line 4 or the wire production line 5 for rolling.

[0028] As one specific implementation, the feeding end of the first heating furnace 6 is provided with a furnace inlet roller conveyor, which is connected to the first cold billet loading platform 61 for feeding cold billets. The cold billets can be transferred from the cold billet storage area to the first cold billet loading platform 61 by a crane for feeding. After the cold billets enter the first heating furnace 6 through the furnace inlet roller conveyor and are heated to the set temperature, they are then sent to the bar production line 4 via the bar straight rolling roller conveyor 2, or sent to the wire rod straight rolling roller conveyor 3 via the billet transverse transfer mechanism 8 and then enter the wire rod production line 5, thus meeting the production needs of bars and wire rods.

[0029] As one specific implementation, the feeding end of the second heating furnace 7 is equipped with a cold billet loading platform, denoted as the second cold billet loading platform 71. The second cold billet loading platform 71 is connected to the furnace inlet roller conveyor of the second heating furnace 7 and is used for cold billet loading. The cold billet can be transferred from the cold billet storage area to the second cold billet loading platform 71 by a crane for loading. After the cold billet enters the second heating furnace 7 via the furnace inlet roller conveyor and is heated to the set temperature, it is then sent to the wire rod production line 5 via the wire rod straight rolling roller conveyor 3, or sequentially sent to the bar production line 4 via the wire rod straight rolling roller conveyor 3, the billet transverse transfer mechanism 8, and the bar straight rolling roller conveyor 2, thus meeting the production needs of bars and wire rods. The steel billet heated by the second heating furnace 7 is sent to the wire rod production line 5 via a short path, which can improve the wire rod production efficiency and meet the demand for high-end wire drawing steel on the wire rod production line.

[0030] To save operating costs, when producing small-sized products, only one heating furnace needs to be operated. Both heating furnaces can meet the needs of conveying steel billets to the two production lines behind the furnace. The bidirectional steel billet transverse transfer mechanism 8 meets the conveying requirements.

[0031] In an optimized implementation, the feed roller conveyor of the second heating furnace 7 is connected to the bar rolling roller conveyor 2, and a steel-separating mechanism 21 is provided at the connection point. The steel-separating mechanism 21 is connected to a steel-separating drive unit 22 for switching between a first working position and a second working position. In the first working position, the channel between the bar production line 4 and the feeding end is connected. In the second working position, the channel between the second heating furnace 7 and the feeding end is connected.

[0032] Specifically, in the bar production process, the high-temperature continuous casting billet output from the continuous casting production line 1 can be directly sent to the bar production line 4 for rolling via the bar straight rolling roller table 2. A steel separating mechanism 21 is provided at the junction of the bar straight rolling roller table 2 and the furnace entry roller table of the second heating furnace 7. The steel separating mechanism 21 can divert and guide the high-temperature continuous casting billet sent to the bar straight rolling roller table 2. When it is in the first working position, the high-temperature continuous casting billet on the bar straight rolling roller table 2 continues to be transported to the bar production line 4 via the bar straight rolling roller table 2. When it is in the second working position, the high-temperature continuous casting billet on the bar straight rolling roller table 2 enters the second heating furnace 7 for heating after passing through the furnace entry roller table of the second heating furnace 7. The heated billet is then sent to the bar production line 4 or the wire rod production line 5. For wire rod products that contain a certain proportion of high-end wire drawing steel, the steel billets need to be heated in a heating furnace to ensure the temperature of the steel billets entering the wire rod production line 5. The high-temperature continuous casting billets output from the continuous casting production line 1 can be further heated in the second heating furnace 7 before being sent to the wire rod production line 5. This ensures the temperature of the steel billets while shortening the conveying path and guaranteeing the demand for high-end wire drawing steel.

[0033] Specifically, there are two types of incoming materials in the second heating furnace 7: one is cold billets fed from the second cold billet feeding platform 71, and the other is hot steel billets from the continuous casting production line 1. The material source can be selected as needed to ensure the production needs of the wire rod production line 5.

[0034] As per the instruction manual Figure 2 As shown, the steel-splitting mechanism 21 includes a fixed base 211 and a steel-splitting component 212. One end of the steel-splitting component 212 is sleeved on the fixed base 211 and can rotate around the fixed base 211. The steel-splitting drive unit 22 is hinged to the steel-splitting component 212 to drive the steel-splitting component 212 to switch between a first working position and a second working position. The steel-splitting drive unit 22 can be a cylinder or a hydraulic rod. The output end of the steel-splitting drive unit 22 is hinged to the middle of the steel-splitting component. By extending or retracting the cylinder or hydraulic rod, the steel-splitting component can be driven to rotate around the fixed base, thereby guiding the steel-splitting component 212 to split the steel.

[0035] In an optimized implementation, the discharge end of the second heating furnace 7 is equipped with a discharge roller conveyor, which includes multiple discharge rollers spaced apart. At the junction of the second heating furnace 7 and the wire rod direct rolling mill 3, the multiple discharge rollers and the wire rod rollers of the wire rod direct rolling mill 3 are alternately arranged along the billet running direction. This allows for a compact layout of the second heating furnace and the wire rod direct rolling mill 3, saving space, and also facilitates the discharge of billets from the second heating furnace 7, which can be directly fed onto the wire rod direct rolling mill 3.

[0036] In this embodiment, all roller conveyors have the same structure, and their dimensions, arrangement positions, and arrangement directions can be set as needed. Each roller conveyor refers to the bar direct rolling roller conveyor 2, the wire rod direct rolling roller conveyor 3, the furnace inlet and outlet roller conveyors of the first heating furnace 6, and the furnace inlet and outlet roller conveyors of the second heating furnace 7. Taking the bar direct rolling roller conveyor 2 as an example, it includes multiple rollers arranged at intervals along the billet running direction. Each roller is connected to a roller drive unit for driving the rollers to rotate, thereby conveying the billet.

[0037] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 3-4As shown, the billet transverse transfer mechanism 8 includes several billet transfer supports 81. The length direction of each billet transfer support 81 is parallel to the transfer direction of the billet on the billet transverse transfer mechanism 8. Each billet transfer support 81 is arranged at intervals perpendicular to the transfer direction of the billet. Each billet transfer support 81 has a groove. Each billet transfer support 81 is equipped with several sprockets. Each groove contains a transmission chain 82. The transmission chain 82 meshes with the corresponding sprocket. The rotation of the sprocket can drive the transmission chain 82 to rotate. Each transmission chain 82 is equipped with a billet transfer block 83. The billet transfer block 83 can move with the transmission chain 82. The billet transfer block 83 can move along the groove. When the billet transfer block 83 moves along the groove, it protrudes from the outside of the groove to push the billet placed on the billet transfer support 81, thereby driving the billet to be transported. One side of one of the steel-moving brackets 81 is provided with a steel-moving drive unit for driving the rotation of each transmission chain 82. Each of the transmission chains 82 is equipped with a chain tensioning device 84 for adjusting the tension of the transmission chain to ensure that the transmission chain rotates forward and backward under the action of the steel-moving drive unit, thus meeting the bidirectional transmission requirements.

[0038] In some embodiments, each of the transmission chains 82 is equipped with a plurality of steel transfer blocks 83, which can sequentially transfer a plurality of steel billets to improve the steel billet transfer efficiency.

[0039] In this embodiment, the billet transverse movement mechanism 8 is equipped with two billet moving drive units, which are respectively located at both ends of the billet moving bracket 81 and are designated as the first billet moving drive unit 85 and the second billet moving drive unit 86. The first billet moving drive unit 85 is connected to a sprocket on the corresponding side via a rotating shaft. The first billet moving drive unit 85 drives the rotating shaft to rotate, thereby driving the sprocket to rotate and realizing the rotation of the transmission chain 82. The second billet moving drive unit 86 is connected to a sprocket on the corresponding side via a rotating shaft. The second billet moving drive unit 86 drives the rotating shaft to rotate, thereby driving the sprocket to rotate and realizing the rotation of the transmission chain 82. The first billet moving drive unit 85 and the chain tensioning device 84 are located on the side near the bar straight rolling mill 2, and the second billet moving drive unit 86 is located on the side near the wire rod straight rolling mill 3. The driving directions of the first billet moving drive unit 85 and the second billet moving drive unit 86 are opposite. During the operation of the billet transverse movement mechanism 8, only one of the billet moving drive units is activated for driving.

[0040] As one specific implementation method, when the steel billet is fed from the bar straight rolling mill 2 to the wire rod straight rolling mill 3, the second steel transfer drive unit 86 is activated. When the steel billet is fed from the wire rod straight rolling mill 3 to the bar straight rolling mill 2, the first steel transfer drive unit 85 is activated.

[0041] In an optimized implementation, the billet transverse movement mechanism 8 further includes several billet platforms 87, with each billet platform 87 and each steel transfer support 81 arranged alternately. The elevation of the billet platform 87 is not lower than the elevation of the steel transfer support 81. The billet is mainly supported on the billet platform 87 and is transferred by the transmission mechanism on the steel transfer support 81.

[0042] In an optimized implementation, the discharge end of the first heating furnace 6 is equipped with a first transfer device 9 for transporting the steel billet from the first heating furnace 6 to the bar straight rolling mill 2 or the steel billet transverse transfer mechanism 8, and for transferring the steel billet from the steel billet transverse transfer mechanism 8 to the bar straight rolling mill 2.

[0043] In some embodiments, the discharge roller conveyor of the first heating furnace 6 extends to be arranged side by side with the bar straight rolling roller conveyor 2 and the billet transverse transfer mechanism 8. The rollers of the discharge roller conveyor and the bar straight rolling roller conveyor 2 are aligned one by one. The first transfer device 9 includes a transfer bracket disposed between adjacent rollers. The transfer bracket is connected to a lifting mechanism and a translation mechanism. The lifting mechanism is disposed on the translation mechanism. The transfer bracket is disposed at the output end of the lifting mechanism. The translation mechanism can move between the discharge roller conveyor, the bar straight rolling roller conveyor 2 and the billet transverse transfer mechanism 8. The transfer bracket is lifted by the lifting mechanism to transfer the billet to the transfer bracket. Then it is moved to the target position by the translation mechanism and lowered by the lifting mechanism to transfer the billet to the target position. This realizes the transfer of the billet on the discharge roller conveyor of the first heating furnace to the bar straight rolling roller conveyor 2 or the billet transverse transfer mechanism 8, and the transfer of the billet on the billet transverse transfer mechanism 8 to the bar straight rolling roller conveyor 2.

[0044] In an optimized implementation, a second transfer device 10 is provided at one end of the billet transverse transfer mechanism 8 near the wire rod straight rolling mill 3 for transferring the billet between the wire rod straight rolling mill 3 and the billet transverse transfer mechanism 8. The second transfer device is used to transfer the billet on the wire rod straight rolling mill 3 to the billet transverse transfer mechanism 8 or to transfer the billet on the billet transverse transfer mechanism 8 to the wire rod straight rolling mill 3.

[0045] In some embodiments, the structure of the second transfer device 10 is the same as that of the first transfer device 9, or an existing steel receiving device is used, which will not be described in detail here.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0047] Those skilled in the art will understand that this invention can be implemented in many other specific forms without departing from the spirit and scope of this invention. Although embodiments of this invention have been described, it should be understood that this invention is not limited to these embodiments, and those skilled in the art can make changes and modifications within the spirit and scope of this invention as defined in the appended claims.
