Description

Technical Field

[0001] The present invention relates to the field of steel or wire rod production, and in particular to a material heat preservation method and device. Background Art

[0002] During the production process, the hot billet of high-speed wire rod must first be rolled and then cooled in the rolling mill. The high-speed rolled coils must pass through a primary slow cooling line (slow cooling roller) and a secondary slow cooling line (slow cooling roller bed) to achieve coils that meet mechanical property requirements. To expand the application range of wire rod, some steel mills have added secondary slow cooling lines and insulation corridors to improve the wire rod's plasticity, drawability, and other process properties.

[0003] Currently, domestic steel companies prefer double insulation corridors, which are relatively advantageous for insulation corridors. Double insulation corridors have advantages over single insulation corridors, including longer insulation time, flexible operation, and stable wire performance. However, most steel companies require manual intervention to implement double insulation corridors, which presents many problems: manual operation or manual intervention can affect the automatic interruption of the slow cooling roller bed, affecting the rolling rhythm and ultimately affecting production; manual operation can easily mix batches (batches of insulated wire coils and batches of uninsulated wire coils), resulting in unstable wire performance and directly affecting product quality; frequent manual intervention increases workers' labor intensity, and improper manual operation can also cause production accidents.

[0068] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0069] It should be noted that the acquisition, transmission, storage, use, and processing of data in the technical solution of this application are in compliance with the relevant provisions of laws and regulations. In the embodiments of this application, certain software, components, models, and other existing solutions in the industry may be mentioned. These should be considered as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of this application, but it does not mean that the applicant has or will necessarily use such solutions.

[0070] Example 1

[0071] Figure 1 Schematic diagram of a material insulation method of the present invention, such as Figure 1 As shown, an embodiment of the present invention provides a method for insulating materials, including: step S101 is to feed materials into a first insulating corridor and obtain first position information of the materials in the first insulating corridor. The first insulating corridor is provided with a heating and / or insulating device for heating and / or insulating the materials.

[0072] Specifically, during the high-speed wire production process, coils of different specifications have different heating and insulation requirements. This application provides an occupancy signal detector within the first insulation corridor to obtain real-time occupancy information of each material within the first insulation corridor, enabling real-time monitoring of the materials. The first occupancy information is the position and insulation duration of n materials in the first insulation corridor, where n is a natural number greater than 0.

[0073] According to a specific embodiment, the occupancy signal detector can be a pressure sensor or an infrared collector. The pressure sensor is arranged on the lower side of the transmission track of the first insulation corridor, or the infrared collector is arranged at the entrance and exit where the material passes. When a material passes by, the occupancy information of the material can be obtained, and the occupancy information can be sent to the central control machine in real time.

[0074] Step S102 is to control the feeding of materials into the second insulation corridor according to the first occupancy information, and obtain the second occupancy information of the materials in the second insulation corridor.

[0075] The first insulation corridor and the second insulation corridor are both provided with occupancy signal detectors for detecting the first occupancy information and the second occupancy information of the materials; the first occupancy information is the position and insulation time of n materials in the first insulation corridor; the second occupancy information is the position and insulation time of m materials in the second insulation corridor, and both n and m are natural numbers greater than 0.

[0076] According to a specific embodiment, controlling the feeding of the second insulation corridor according to the first occupancy information includes: when the first occupancy information meets a first process threshold, controlling the feeding of the second insulation corridor.

[0077] The rolling interval T is set by the process to calculate the travel speed V that meets the production rhythm, and then the travel time P of the first roller bed is calculated. The travel time of the second roller bed can be calculated through the travel time of the first roller bed. Through this deduction, the travel time of each roller bed can be calculated. The first process threshold is determined according to the calculated travel speed V and travel time P. That is, when the first occupancy information meets the first process threshold, the second insulation corridor starts the feeding action, so that the head material to be exported in the first insulation corridor meets the said process requirements.

[0078] For example: the passage speed of the corridor is: V = D / T / F, and the passage time is: P = D / V / F + U, where P is the passage time, D is the distance between roller beds, T is the rolling interval, V is the corridor entrance speed, F is the forward slip value of the roller bed, and U is the passage time of the upstream roller bed.

[0079] Step S103 is to control the feeding of materials into the first insulation corridor according to the second occupancy information, and obtain the first occupancy information of the materials in the first insulation corridor.

[0080] According to a specific embodiment, controlling the feeding of materials into the first insulation corridor according to the second placeholder information includes: when the second placeholder information meets a second process threshold, controlling the feeding of materials into the first insulation corridor.

[0081] Specifically, the corridor parameters such as the length, travel speed, and travel time of the second insulation corridor, as well as the process requirements (such as temperature requirements) of the material (such as the wire coil) are obtained, and the second process threshold is determined according to the corridor parameters and process requirements. That is, when the second occupancy information meets the second process threshold, the first insulation corridor starts the material feeding action, so that the head material to be exported in the second insulation corridor meets the process requirements.

[0082] Step S104 is to control the discharge of the first insulation corridor and / or the second insulation corridor according to the first occupancy information and / or the second occupancy information, so that the discharge meets the insulation requirements.

[0083] According to a specific embodiment, the discharge of the first insulation corridor and / or the second insulation corridor is controlled according to the first occupancy information and / or the second occupancy information, respectively, including: determining the insulation result of the head material to be exported in the first insulation corridor according to the first occupancy information, and controlling the first insulation corridor to discharge the material according to the insulation result; determining the insulation result of the head material to be exported in the second insulation corridor according to the second occupancy information, and controlling the second insulation corridor to discharge the material according to the insulation result.

[0084] Specifically, the insulation result of the head material to be exported in the first insulation corridor is predicted based on the first occupancy information, the heating coefficient of the first insulation corridor and the first material moving speed. When the insulation result meets the process threshold, the first insulation corridor is controlled to discharge the material; the insulation result of the head material to be exported in the second insulation corridor is predicted based on the second occupancy information, the heating coefficient of the second insulation corridor and the second material moving speed. When the insulation result meets the process threshold, the second insulation corridor is controlled to discharge the material.

[0085] The method of predicting the insulation result of the head material to be exported from the first insulation corridor based on the first occupancy information, the heating coefficient of the first insulation corridor and the first material moving speed includes: determining the remaining travel time of the head material to reach the exit of the first insulation corridor based on the first occupancy information and the first material moving speed; determining the insulation result of the head material when it reaches the exit of the first insulation corridor based on the first occupancy information, the heating coefficient of the first insulation corridor and the remaining travel time; predicting the insulation result of the head material to be exported from the second insulation corridor based on the second occupancy information, the heating coefficient of the second insulation corridor and the second material moving speed, including: determining the remaining travel time of the head material to reach the exit of the second insulation corridor based on the second occupancy information and the second material moving speed; determining the insulation result of the head material when it reaches the exit of the second insulation corridor based on the second occupancy information, the heating coefficient of the second insulation corridor and the remaining travel time.

[0086] The method further includes: the first insulation corridor and the second insulation corridor are rotatable corridors, and the inlet and outlet directions thereof are adjusted by rotating the first insulation corridor and / or the second insulation corridor. The adjusting the inlet and outlet directions thereof by rotating the first insulation corridor and / or the second insulation corridor includes: controlling the first insulation corridor or the second insulation corridor to rotate the entrance to connect with the front conveying roller bed for feeding before the first insulation corridor or the second insulation corridor is fed; and controlling the first insulation corridor or the second insulation corridor to rotate the exit to connect with the rear conveying roller bed for discharging before the first insulation corridor or the second insulation corridor is discharged.

[0087] The materials in the first insulation corridor and the second insulation corridor are both steel wires; the steel wires move at a uniform speed in the first insulation corridor and the second insulation corridor.

[0088] The entrance of the first insulation corridor and the entrance of the second insulation corridor can be connected, and the first insulation corridor and the second insulation corridor can be fed separately by switching. The entrance of the first insulation corridor and the entrance of the second insulation corridor can also be separated, and the materials can be fed separately or simultaneously.

[0089] The outlet of the first insulation corridor and the outlet of the second insulation corridor can be connected, and the first insulation corridor and the second insulation corridor can be switched to realize separate discharge of materials. The outlet of the first insulation corridor and the outlet of the second insulation corridor can also be separated, and the materials can be discharged separately or simultaneously.

[0090] The discharge and feeding of the first insulation corridor and the second insulation corridor can be synchronized, or can be done separately, such as opening only the entrance or the exit. This application can achieve the stable switching of the first insulation corridor and the second insulation corridor, ensuring the production rhythm of enterprises such as steel.

[0091] This application identifies and tracks the materials in the corridor, determines the insulation time and rolling rhythm of the wire coil of the corresponding specification according to the process parameters of the corresponding specification, realizes the automatic and complete matching of the slow cooling roller bed, and the identification and tracking of insulated batches and uninsulated batches in the insulation corridor.

[0092] Example 2

[0093] Figure 2 This is a schematic diagram of an embodiment of the present invention, which mainly consists of a collection area PLC system, a human-machine interface, a network system, a transmission device, an on-site detection element, etc. Figure 2 As shown: The high-speed collection PLC is used for data acquisition, product conveying control, product cooling control, and mill unloading control. The high-speed collection PLC is the brain of the system, providing data support for its automatic operation. The human-machine interface is used to display product tracking, set speed advance rate, speed display, and set delay time. The network system connects various systems for data exchange. The transmission device is used to execute speed commands generated by the PLC and control the collection equipment. On-site detection elements are used for on-site hot and cold metal detectors to achieve automatic control and tracking of the insulation corridor, and occupancy proximity switch detection enters the PLC for sequential control to achieve automatic slow cooling roller.

[0094] like Figure 3 As shown in the figure, the identification of insulated and uninsulated batches is achieved by tracking the occupancy signals of the insulation corridor roller beds one by one. The red dots in the figure indicate that the insulated batch (material) is being discharged, and the yellow dots indicate that the uninsulated batch is being fed in. Insulated and uninsulated batches are identified and tracked in real time. When the yellow dots step to the last roller bed, the newly fed batch enters the insulation state.

[0095] Entrance automation mainly deals with the control of entrance direction, which plays a key role in the overall automation. Figure 4As shown, the control of the entrance direction can be divided into two modes: manual and automatic. In manual mode, the direction of the entrance can be switched on the interface. Even if the direction is switched manually, there are interlocking conditions, and the interface will prompt whether the direction switching is allowed. In automatic mode, the interface displays the switching direction in real time. The entrance tracking is completed by the occupancy signal of the roller bed at the entrance of the insulation corridor to realize the processing of the residual material in the entrance direction. When the entrance is switched from corridor A to corridor B, it is necessary to ensure that the first rotating roller bed 31 and the second rotating roller bed 7 in the figure rotate, and the third rotating roller bed 30, the fourth rotating roller bed 29 and the fifth rotating roller bed 6 do not leave any residual material. Similarly, when the entrance is switched from corridor B to corridor A, it is necessary to ensure that the sixth rotating roller bed 27, the seventh rotating roller bed 26 and the eighth rotating roller bed 5 in the figure do not leave any residual material.

[0096] The export automation mainly deals with the control of the export direction, and it also plays an important role in the overall automation. Figure 5 As shown, the control of the exit direction is also divided into two modes: manual and automatic. Manual mode: In automatic mode, the "export automatic switching" operation switches to manual mode. In manual mode, the direction of the exit can be switched on the interface. Even if the direction is switched manually, there are interlocking conditions. The interface will prompt whether the direction switching is allowed. Automatic mode: In manual mode, the "export manual switching" operation switches to automatic mode. In automatic mode, the interface will display the switching direction in real time. The exit direction tracking is completed by the occupancy signal of the roller bed at the exit of the insulation corridor to realize the residual material processing in the exit direction. When the exit side switches from corridor A to corridor B, it must be ensured that the ninth rotating roller bed 11 in the figure does not leave any residual material. Similarly, when the exit side switches from corridor B to corridor A, it must be ensured that the tenth rotating roller bed 10 in the figure does not leave any residual material.

[0097] The control modes of the slow cooling corridor roller bed are divided into single corridor and double corridor modes, and are divided into slow cooling corridor A line, slow cooling corridor B line and slow cooling corridor A+B mode. The control modes of the slow cooling corridor roller bed are divided into manual and automatic modes. The manual mode can be further divided into local manual and centralized manual mode. Manual control principle: Select the roller bed to be operated on the local box or interface, and then you can operate the selected roller bed on the local box or interface accordingly. Automatic control principle: In fact, it is implemented in the conventional stack sequence control method.

[0098] Each roller bed is associated with a corresponding photoelectric switch. When a core rack is transported to the first conveyor roller bed, the photoelectric switch on the conveyor roller bed will generate a signal, which is displayed on the interface. If a core rack is present on the second conveyor roller bed in the forward direction and the core rack is not being transported forward, the conveyor roller bed with the core rack will stop. If a core rack is present on the second conveyor roller bed in the forward direction and is being transported to the third conveyor roller bed, the conveyor roller bed with the core rack will continue to transport the core rack to the second conveyor roller bed, and both core racks will be transported forward simultaneously.

[0099] This embodiment achieves automatic and stable operation of the dual-corridor system, solves the technical difficulties of high-speed wire corridor control, provides users with a reliable and stable control method, and realizes the rolling of high-speed wire steel varieties, thereby helping users to improve production rhythm and increase output, which can reduce the initial investment for steel companies and bring extremely considerable economic benefits in future production. The automatic and stable operation of the dual-corridor slow cooling roller bed can better help users improve production rhythm and increase output. Compared with the manual mode and the production rhythm that cannot be fully automated and requires manual intervention, it increases output by about 2%, which can bring extremely considerable economic benefits to steel companies.

[0104] The insulation result of the head material to be exported in the second insulation corridor is predicted based on the second occupancy information, the heating coefficient of the second insulation corridor and the second material moving speed. When the insulation result meets the process threshold, the second insulation corridor is controlled to discharge the material.
