Description

Technical Field

[0001] The present application relates to the technical field of strip steel, and in particular to a strip head tilting device and a pickling mill. Background Art

[0002] The pickling mill is a device used for rolling steel, which mainly includes processes such as pickling, rolling and shearing. During maintenance and abnormal strip breakage, the strip needs to be threaded through the mill. The strip threading through the mill includes making the strip head, that is, lifting the strip head by about 20-50 mm to facilitate the rolling mill to pass the strip into the interior of the mill.

[0003] Currently, when making a strip head, at least 2-3 operators are required to place a round tube about 2.5-3 meters long and 13 mm in diameter under the strip head. Then, a strip pressing device is used to press the strip head down. On the one hand, this requires a large number of operators, which is time-consuming and labor-intensive. On the other hand, because the round tube is easily displaced during the pressurization process, the strip head usually does not tilt into place during a single pressurization. Therefore, the round tube must be pulled and pressurized multiple times. When pulling and pulling the round tube, because the surface of the round tube is lubricated, it is easy to slip, which not only poses a safety hazard but also makes the operation difficult.

[0046] Figure 1 A schematic diagram showing a strip head tilting device supporting a supporting mechanism in an embodiment of the present application is shown. Figure 2 A schematic diagram showing a strip head tilting device in an embodiment of the present application, in which a supporting mechanism supports the strip head and a pressing mechanism presses the strip head downward. Figure 3 A schematic diagram showing a strip head tilting device in an embodiment of the present application in which the supporting mechanism does not support the strip head and the pressing mechanism does not press down the strip head is shown. Figures 1 to 3In the figure, 1 is the pressing mechanism, 2 is the strip steel, 3 is the top plate, and 4 is the strip guide plate. Figures 1 to 3 , provides a head lifting device, which includes at least a pressing mechanism and a supporting mechanism, which are described in detail as follows:

[0047] The pressing mechanism presses down the strip head from above.

[0048] Specifically, the pressing mechanism can be set close to the free end of the strip head, for example, 50 cm away from the free end of the strip head. The free end of the strip head can be understood as the end of the strip head, that is, Figures 1 to 3 The right end of the middle strip and the top of the strip head are the upper positions of the strip during strip production. Pressing down the strip head can be understood as pressing the strip head from top to bottom to make the strip head move downward.

[0049] The supporting mechanism is located between the pressing mechanism and the free end of the strip head, and supports the strip head from below to make the strip head suspended in the air.

[0050] Specifically, the lower part of the strip head is the lower position of the strip during production, and the supporting mechanism is located between the pressing mechanism and the free end of the strip head. It can be understood that the pressing mechanism, the supporting mechanism and the free end of the strip head are distributed in sequence along the length direction of the strip. The supporting mechanism supports the strip head so that the strip head is suspended in the air. The pressing mechanism presses on the strip head, and the free end of the strip head can be tilted, so that the strip head can be tilted for the purpose of threading the strip through the rolling mill.

[0051] Optionally, the holding mechanism includes:

[0052] Top plate, located below the strip head;

[0053] The lifting component is fixedly connected to the top plate and drives the top plate to rise, supporting the strip head through the top plate.

[0054] Specifically, the lifting component drives the top plate to rise, so that the top plate contacts the lower end of the strip head to support the strip head.

[0055] Optionally, the top plate is parallel to the width direction of the steel strip, so that the top plate supports the steel strip from the width direction of the steel strip.

[0056] Optionally, the top plate is rectangular, and its length direction is parallel to the width direction of the strip.

[0057] Optionally, the length of the top plate is greater than the width of the bandwidth.

[0058] Optionally, when the top plate is against the steel strip, both ends of the top plate in the length direction are located on the outside of the steel strip in the width direction.

[0059] Figure 4Schematic diagram of the tape threading guide plate in the embodiment of the present application is shown. Figure 4 In the figure, 3 is the top plate, 5 is the belt guide plate, and optionally, see Figure 4 The top plate is obtained by cutting the strip guide. Since the strip guide is an existing component and is located between the strip pressing device and the cross-cutting shear at the rolling mill entrance, the top plate is processed using existing components and does not need to be prepared separately, which effectively reduces costs, reduces the space occupied by equipment, and has the advantage of simple structure.

[0060] Specifically, there is a gap between the strip guide plate and the lower end of the strip head. The top plate is driven up by the lifting component, and the top plate can support the strip head. The pressing mechanism presses the strip head downward, and the strip head can be tilted up.

[0061] Optionally, the belt threading guide plate further includes a fixing plate, on which a receiving hole or receiving notch matching the top plate is provided, and the shape of the receiving hole or receiving notch can be set as required.

[0062] For example, Figure 4 In the middle, the accommodating hole is square, the length of the belt guide is 2m, and the width is 200mm. From the middle and rear position of the belt guide, a top plate with a length of 1.8m and a width of 70 to 80mm is cut out.

[0063] Figure 5 Schematic diagram of the lifting component in the embodiment of the present application is shown. Figure 5 In the figure, 3 is a top plate, 6 is a scissor jack, 7 is a lead screw, and 8 is a base. Optionally, the lifting components include:

[0064] A base, fixedly set on the ground;

[0065] The lifting component has a lower end fixed on the base and an upper end fixedly connected to the lower end of the top plate.

[0066] Optionally, the lifting assembly includes at least two scissor jacks, and the scissor jacks are lifted and lowered by the same screw, which can be a hand-cranked screw. The hand-cranked screw can realize synchronous lifting and lowering of the scissor jacks.

[0067] Optionally, the lifting assembly includes at least two lifting cylinders or at least two lifting hydraulic cylinders or at least two electric push rods.

[0068] Optionally, the pressing mechanism is a strip pressing device.

[0069] Optionally, the pressing mechanism includes:

[0070] The pressurizing cylinder is located above the strip steel head. The end of the piston rod of the pressurizing cylinder is connected with a pressing head, and the pressing head is used to press the strip steel head.

[0071] According to a second aspect of the present application, a pickling mill is provided, comprising the above-mentioned strip head tilting device.

[0072] Figure 6 A flowchart of a method for lifting a lead is shown in an embodiment of the present application. Figures 1 to 6 According to a third aspect of the present application, a method for warping a lead is provided, comprising:

[0073] S1: Use a supporting mechanism to support the strip head from below so that the strip head is suspended in the air;

[0074] S2: Use a pressing mechanism to press down the steel strip head from above so that the free end of the steel strip head is tilted upward.

[0075] Optionally, after the free end of the steel strip head is tilted upward, the method further comprises:

[0076] The pressing mechanism is separated from the strip head and does not press down the strip head;

[0077] The supporting mechanism is separated from the strip steel head and does not support the strip steel head;

[0078] The warped strip head is used to thread the strip through the rolling mill and carry out normal strip production.

[0079] Specifically, the supporting mechanism is separated from the strip head, that is, the lifting component drives the top plate to descend.

[0080] In addition, when the top plate is cut by the strip guide, the top plate drops to a position flush with the strip guide, and the top plate and the fixed plate form a complete strip guide. The strip guide can perform corresponding work and the strip can be produced normally.

[0081] In this application, the strip head is supported by a supporting mechanism, and then the strip head is pressed down by a pressing mechanism, so that the strip head is tilted. In the above process, the operator does not need to carry the round tube, which can effectively reduce labor intensity.
