Description

Technical Field

[0001] This utility model relates to the field of steel strip production, and in particular to a steel strip spheroidizing annealing treatment device. Background Technology

[0002] The main purpose of steel strip annealing is to eliminate work hardening that occurred during the previous cold working process by heating the steel strip to an appropriate temperature, holding it at that temperature, and then slowly cooling it. This process effectively reduces the hardness and strength of the steel strip, restores its plasticity and toughness, improves its internal grain structure, and eliminates internal stress, thus preparing it for subsequent deep drawing, bending, and other reprocessing, and improving the formability and dimensional stability of the product.

[0003] A search revealed patent publication number CN216237204U, which discloses a steel strip annealing and cooling device. The device includes a base plate with a housing fixedly connected to the top. A partition is located inside the housing, and a first processing chamber and a second processing chamber are respectively located on both sides of the partition. An annealing mechanism is located in the first processing chamber. Two corresponding feeding guide rollers are located on the left side of the annealing mechanism, and a tensioning mechanism is located on the right side. Two corresponding guide rollers are located in the second processing chamber, with a chip removal mechanism between them. A cooling mechanism and a chip collection mechanism are respectively located on both sides of the second processing chamber. Both the cooling mechanism and the chip collection mechanism are mounted on the housing. This steel strip annealing and cooling device includes a tensioning mechanism to ensure the steel strip remains taut as it passes through the annealing mechanism, preventing damage to the annealing mechanism from the high temperature. The chip removal and chip collection mechanisms facilitate the removal and collection of dust and debris from the outer surface of the steel strip.

[0004] While existing technologies can achieve certain steel strip annealing treatments, they suffer from drawbacks such as uneven heating, low loading and unloading efficiency, and inconvenient operation during the annealing process of existing steel coils, leading to unstable annealing quality and high energy consumption. In view of this, we propose a steel strip spheroidizing annealing treatment device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a steel strip spheroidizing annealing treatment device.

[0006] The technical solution of this utility model: A steel strip spheroidizing annealing treatment device, comprising a box, a turntable, a lifting block and a moving plate. The turntable is provided at the lower end of the box, a heating port is provided below the turntable, and an air vent is provided above the right side of the heating port. A moving block is inserted into one side of the box, a lead screw is provided inside the moving block, and a second motor for driving the lead screw to rotate is provided on one side of the moving block. The moving block is threadedly connected to the surface of the lead screw, and a moving plate is provided at the upper end of the moving block. The surface of the turntable is provided with cross-shaped grooves, and the inner wall of the box is provided with a guide groove.

[0007] In use, the steel coil to be annealed can be placed on the upper part of the moving plate. Then, the moving plate is driven by the lead screw of motor 2 to move inside the chamber. The moving plate can be inserted into the groove. Then, the hydraulic cylinder drives the lifting frame to move down a short distance, so that the steel coil can sit on the upper part of the turntable. Then, the moving plate is removed and the moving door is closed. Then, the heating port heats up, and the blower sprays hot air from the bottom. The heat wave can form a vortex inside the chamber under the action of the guide groove, thus achieving uniform heating of the steel coil. Hot air can also enter the groove from the air inlet to heat the bottom of the steel coil. Motor 1 can drive the turntable to rotate at a constant speed through gear 1 and gear 2 to achieve a uniform heating effect on the steel coil. After annealing, the original feeding process can be used for unloading, which facilitates the uniform annealing effect of the steel coil and the loading and unloading of the steel coil. It has high practicality.

[0008] Preferably, the lower end of the housing is provided with a bracket, and the lower end of the bracket is fixed with a base. A button is provided on one side of the lifting block. The button is used to control the movement of motor one and motor two. The bracket and base enhance the overall structural stability and load-bearing capacity of the equipment, while raising the bottom of the housing, providing sufficient installation and maintenance space for the bottom heating and transmission mechanism.

[0009] Preferably, a hydraulic cylinder is embedded in one side of the housing, and the output end of the hydraulic cylinder is fixedly connected to the lower end of the lifting block. A synchronizer is fixed on one side of the housing. The hydraulic drive provides a smooth and powerful lifting force, ensuring that the steel coil lifting process is stable and reliable. The synchronizer ensures precise control and synchronization of the lifting action, avoiding uneven loading or jamming.

[0010] Preferably, a bracket is provided at the lower end of one side of the lifting block, and the lower end of the bracket is an adjustable telescopic leg (the telescopic leg is manually adjustable in height and is not shown in the figure here) to assist in balance. The adjustable telescopic leg can flexibly adapt to steel coils of different specifications or slightly uneven placement surfaces, providing additional stability during lifting and support, and preventing the equipment from tipping over or the steel coil from shifting.

[0011] Preferably, a temperature sensor is provided on one side of the chamber, a controller is provided on one side of the chamber, and an air outlet is provided at the top of the chamber. The temperature sensor and the controller form a closed-loop temperature control system to achieve accurate monitoring and automatic adjustment of the annealing temperature. The air outlet ensures the balance of air pressure inside the chamber and the smooth discharge of waste heat, maintaining a stable heat treatment environment.

[0012] Preferably, a heater is fixed at the lower end of the housing, and the heater is used in conjunction with the heating port. A sliding door is inserted into one side of the housing, and a handle is fixed to one side of the sliding door. A blower is provided on one side of the housing, and the blower is connected to the air outlet. The integrated heater and blower provide a high-efficiency, centralized heat source and airflow circulation power. The sliding door design facilitates sealing and opening / closing, is easy to operate, effectively reduces heat loss, and improves energy utilization.

[0013] Preferably, a second gear is fixed at the lower end of the turntable, and a first gear is provided at the lower end of the housing. The first gear meshes with the second gear. A first motor is fixed at the lower end of the housing. The output shaft of the first motor is fixedly connected to the rotation center at the lower end of the first gear. The turntable is driven to rotate at a uniform speed through the gear transmission mechanism. The transmission is smooth and the torque is large, ensuring that the steel coil can receive heat radiation and convection from all directions evenly during the heating process, eliminating the phenomenon of local overheating or underheating.

[0014] Preferably, the turntable has an air inlet arranged in a ring array on its side. The air inlet is connected to the bottom of the groove. The ring array of air inlets directly introduces hot air into the bottom of the turntable groove, realizing direct heating of the bottom and inner side of the steel coil. This makes up for the deficiency of insufficient bottom heating in traditional annealing equipment, and makes the steel coil more fully and thoroughly heated.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model achieves high efficiency, uniformity, and intelligence throughout the entire steel coil annealing process by integrating an automated loading and unloading mechanism, a multi-directional hot air circulation system, and a uniform-speed rotating worktable. The screw-driven moving plate enables automatic pushing and precise positioning of the steel coil, ensuring it accurately falls into the cross groove of the turntable, greatly improving loading and unloading efficiency and reducing manual labor intensity and safety hazards. The hydraulically driven lifting block ensures the smooth placement and removal of the steel coil on the turntable, with smooth and reliable operation. In the heating stage, the bottom heating port and side air vents work together, combined with the guide channel design on the inner wall of the chamber, to create a uniform vortex heat field within the sealed space, ensuring that heat is applied to the steel coil without any dead angles. Simultaneously, the motor drives the turntable to rotate at a uniform speed through a gear set, ensuring even heating of the entire steel coil and effectively avoiding uneven heating or localized overheating caused by static heating. This combination of mechanical automation and refined thermal field control not only significantly improves the uniformity and stability of annealing quality but also effectively shortens the process cycle and reduces energy consumption, possessing high practicality and market competitiveness.

[0017] II. Based on the first beneficial effect, this utility model excels in improving annealing uniformity and quality stability. Traditional annealing equipment often relies on a single-direction heat source or static heating, which easily leads to temperature differences between the inner and outer rings and the upper and lower surfaces of the steel coil, resulting in uneven annealing hardness. This device innovatively adopts a composite heating mode of "bottom direct blowing + lateral vortex + overall rotation". The cross grooves on the surface of the turntable, combined with the annular array of air inlets, ensure that hot air can effectively enter from the bottom of the steel coil, directly heating its lower surface and inner ring. The guide grooves on the inner wall of the chamber guide the hot air to form a vortex around the steel coil, uniformly heating the upper surface and side walls. The continuous uniform rotation of the turntable dynamically changes the position of the steel coil relative to the hot air field, allowing each part to periodically receive the strongest and weakest thermal shocks, ultimately achieving statistically extreme uniformity. This multi-dimensional homogenization design fundamentally solves the pain points of traditional processes, making the microstructure and properties of the treated steel coil more uniform, greatly improving the product qualification rate and high-end application potential.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
