Description

Technical Field

[0001] This utility model relates to the field of casting and rolling equipment technology, and in particular to continuous casting and rolling equipment for high alloy steel strips. Background Technology

[0002] High-alloy steel strip continuous casting and rolling equipment is a specialized production line for producing high-alloy steel strips. This equipment typically consists of a series of automated systems, enabling efficient and high-quality production of high-alloy steel strips. It is widely used in the production of high-alloy steel strips in industries such as automobiles, aerospace, and electronics. This article will discuss the specific details and characteristics of high-alloy steel strip production equipment.

[0003] When using existing casting and rolling equipment, heated billets need to be hot-rolled to achieve the required thickness and width. However, after hot-rolling the billets to the required thickness, the width is usually achieved by hammering. At this time, the thickness of the billets increases due to the hammering of the sides, which reduces the production quality of the billet processing. In addition, when hot-rolling to ensure that the required thickness is achieved, waste residue will form on the surface of the billets, which needs to be cleaned in time. Therefore, it is necessary to design a continuous casting and rolling equipment for high alloy steel strips. Utility Model Content

[0004] The main purpose of this invention is to provide a continuous casting and rolling equipment for high alloy steel strips, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A continuous casting and rolling equipment for high alloy steel strip includes a base, a bottom plate on the upper surface of the base, auxiliary rollers rotatably connected to the upper surface of the bottom plate, and two gantry frames fixedly connected to the upper surface of the base. There are two auxiliary rollers. A hydraulic rod is provided on the upper surface of the gantry frame, with its output end penetrating the upper surface of the gantry frame and extending to one side of the inner surface of the gantry frame. A top frame is fixedly connected to the output end of the hydraulic rod, and a drive roller is rotatably connected to the inner surface of the top frame. A limiting component is fixedly connected to one side of the top frame, and a pressure plate is slidably connected to the inner wall of the limiting component. A bidirectional screw is rotatably connected to the inner surface of the gantry frame, rotating with the limiting component and threadedly connected to the pressure plate. A roller is rotatably connected to the lower surface of the pressure plate.

[0007] To limit the position of the pressure plate, a fixing plate is fixedly connected to one side of the gantry frame, and a crossbar is fixedly connected to the inner surface of the fixing plate. The crossbar is slidably connected to the pressure plate.

[0008] In order to enable the piston rod to move, mounting bases are fixedly connected to both the front and back of the base plate. A cylinder is mounted on the upper surface of the mounting base, and a piston rod is fixedly connected to the output end of the cylinder.

[0009] To enable hammering of the side of the steel strip, a hammer block is fixedly connected to one end of the piston rod.

[0010] To facilitate the collection of iron slag, a bracket is fixedly connected to the front of the base plate, a rotating shaft is rotatably connected to the inner surface of the bracket, a fan blade is fixedly connected to one end of the rotating shaft, a wind duct is fixedly connected to the inner surface of the bracket, a collection box is fixedly connected to the upper surface of the base, and an opening and closing door is provided on the back of the collection box.

[0011] To enable rotation, a drive motor is mounted on the front of the bracket, and the output end of the drive motor is fixedly connected to the rotating shaft.

[0012] In order to enable the bidirectional screw to rotate, a first motor is installed on one side of the top frame, and the output end of the first motor is fixedly connected to the drive roller. A second motor is installed on the outer surface of the gantry frame, and the output end of the second motor is fixedly connected to the bidirectional screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, through the arrangement of auxiliary rollers, gantry frames, hydraulic rods, top frames, limiting components, and drums, during use, one end of the cast and heated steel strip blank passes through the auxiliary roller of the first gantry frame. At this time, the hydraulic rod runs and drives the active roller to press down. When the active roller rotates, it can carry the steel strip blank through. When it passes through the auxiliary roller of the second gantry frame, the hydraulic rod drives the active roller to press down and hot roll the heated steel strip blank to achieve the required steel strip thickness. When the gantry frame drives the top frame to move down, the pressure plate can press down on the hot-rolled steel strip. At this time, when the width of the steel strip is hammered, it can be ensured that the steel strip thickness does not change, ensuring a constant steel strip thickness and guaranteeing production quality.

[0015] 2. In this utility model, through the arrangement of a base plate, bracket, rotating shaft, fan blades, air duct, collection box, and opening / closing door, when the steel strip passes through the first gantry and the active roller of the second gantry moves down to hot roll the steel strip, waste residue may be generated during hot rolling due to the heat treatment of the steel strip itself. At this time, the rotating shaft rotates to drive the fan blades to run and generate wind. Under the restriction of wind force and direction by the air duct, the wind force blows the waste residue into the collection box and it falls into the collection box along the inner wall of the collection box, which is convenient for collecting the waste residue generated during hot rolling. The opening / closing door can facilitate the cleaning of the collection box after the waste residue is collected. Attached Figure Description

[0027] In this embodiment, a limiting component 8 is fixedly connected to one side of the top frame 6, a pressure plate 9 is slidably connected to the inner wall of the limiting component 8, a bidirectional screw 10 is rotatably connected to the inner surface of the gantry frame 4, the bidirectional screw 10 is rotatably connected to the limiting component 8, the bidirectional screw 10 is threadedly connected to the pressure plate 9, and a roller 11 is rotatably connected to the lower surface of the pressure plate 9.

[0028] In practical use, one end of the cast and heated steel strip blank passes through the auxiliary roller 3 of the first gantry 4. At this time, the hydraulic rod 5 drives the active roller 7 to press down. When the active roller 7 rotates, it can carry the steel strip blank through. When it passes through the auxiliary roller 3 of the second gantry 4, the hydraulic rod 5 drives the active roller 7 to press down and hot roll the heated steel strip blank to achieve the required steel strip thickness. When the gantry 4 drives the top frame 6 to move down, the pressure plate 9 can press down the hot rolled steel strip. At this time, when the width of the steel strip is hammered, it can ensure that the thickness of the steel strip will not change. When the bidirectional screw 10 rotates, it can perform threaded movement with the pressure plate 9, so that the pressure plate 9 can extend or retract into the limiting component 8, thereby facilitating adjustment according to the width of the passing steel strip.

[0029] In this embodiment, a fixing plate 12 is fixedly connected to one side of the gantry frame 4, and a crossbar 13 is fixedly connected to the inner surface of the fixing plate 12. The crossbar 13 is slidably connected to the pressure plate 9.

[0031] In this embodiment, mounting bases 14 are fixedly connected to both the front and back sides of the base plate 2. A cylinder 15 is mounted on the upper surface of the mounting base 14, and a piston rod 16 is fixedly connected to the output end of the cylinder 15.

[0032] In practical use, when the cylinder 15 is running, its output end can drive the extension and retraction of the piston rod 16.

[0033] In this embodiment, a hammer block 17 is fixedly connected to one end of the piston rod 16.

[0034] In practical use, when the piston rod 16 extends or retracts, it can drive the hammer block 17 to move and hammer both sides of the steel strip to achieve the required steel strip thickness.

[0036] In practical use, after the steel strip passes through the first gantry 4, the active roller 7 of the second gantry 4 moves down to hot roll the steel strip. Since the steel strip itself has been heated, waste residue may be generated during hot rolling. At this time, the rotating shaft 19 rotates, driving the fan blade 20 to run and generate wind. Under the restriction of wind force and direction by the air duct 21, the wind force blows the waste residue towards the collection box 22 and falls into the collection box 22 along the inner wall of the collection box 22, which is convenient for collecting the waste residue generated during hot rolling. The opening and closing door 23 can facilitate the cleaning of the collection box 22 after the waste residue is collected.

[0037] In this embodiment, a drive motor 24 is mounted on the front of the bracket 18, and the output end of the drive motor 24 is fixedly connected to the rotating shaft 19.

[0038] In practical use, the drive motor 24 can drive the rotation of the rotating shaft 19 when it is running.

[0039] In this embodiment, a first motor 25 is installed on one side of the top frame 6, and the output end of the first motor 25 is fixedly connected to the drive roller 7. A second motor 26 is installed on the outer surface of the gantry frame 4, and the output end of the second motor 26 is fixedly connected to the bidirectional screw 10.

[0040] In practical use, when the first motor 25 is running, its output end can drive the rotation of the active roller 7, and when the second motor 26 rotates, its output end can drive the rotation of the bidirectional screw 10.

[0041] Working Principle: In operation, one end of the cast and heated steel strip blank passes through the auxiliary roller 3 of the first gantry 4. At this time, the hydraulic rod 5 drives the active roller 7 to press down. When the first motor 25 runs, its output end can drive the rotation of the active roller 7. When the active roller 7 rotates, it can carry the steel strip blank through. When it passes through the auxiliary roller 3 of the second gantry 4, the hydraulic rod 5 drives the active roller 7 to press down and hot roll the heated steel strip blank to achieve the required steel strip thickness. When the gantry 4 drives the top frame 6 to move down, the pressure plate 9 can press down on the hot-rolled steel strip. At this time, when the width of the steel strip is hammered, it can ensure that the thickness of the steel strip does not change. When the second motor 26 rotates, its output end can drive the rotation of the double-headed screw 10. When the double-headed screw 10 rotates, it can perform threaded movement with the pressure plate 9, so that the pressure plate 9 can... Extending or retracting into the limiting component 8 facilitates adjustment based on the width of the passing steel strip. When the cylinder 15 is running, its output end can drive the piston rod 16 to extend or retract. When the piston rod 16 extends or retracts, it can drive the hammer block 17 to move and hammer both sides of the steel strip to achieve the required steel strip thickness. After the steel strip passes through the first gantry 4, when the active roller 7 of the second gantry 4 moves down to hot roll the steel strip, waste residue may be generated during hot rolling due to the heat treatment of the steel strip itself. At this time, the rotating shaft 19 rotates to drive the fan blade 20 to run and generate wind. Under the restriction of wind force and direction by the air duct 21, the wind force blows the waste residue towards the collection box 22 and falls into the collection box 22 along the inner wall of the collection box 22, which facilitates the collection of waste residue generated during hot rolling. The opening and closing door 23 facilitates the cleaning of the collection box 22 after the waste residue is collected.
