Stepping Beam
Stepping Beam is a conveying device used in the steel or metal working industry to transfer hot rolled steel from one machine to another. Stepper beams work by moving the steel step by step to ensure its stable and safe movement. Stepper beams need to bear the weight of steel, so their material needs to be of high strength and rigidity.

Product Description
Stepping Beam is a conveying device used in the steel or metal working industry to transfer hot rolled steel from one machine to another. Stepper beams work by moving the steel step by step to ensure its stable and safe movement. Stepper beams need to bear the weight of steel, so their material needs to be of high strength and rigidity. Stepper beams may come into contact with a variety of corrosive media, such as iron filings, coolants, etc., so the material needs to have adequate corrosion resistance. Stepper beams can be adapted to different production environments and requirements, including different temperatures, speeds and loads.
The stepping beam is a kind of equipment which realizes the material conveying through the step movement. In the steel industry, walking beam is one of the most commonly used steel coil transportation equipment in rolling mills. Whether it is the steel coil coming out of the hot rolling coiler, or the entrance and exit of the cold rolling, galvanizing, and even withdrawing line, the stepping beam plays a vital role. According to the different position of the stepping beam, it is usually divided into the entrance stepping beam and the exit stepping beam. These stepper beams are generally located underground, and the steel coil is carried by a specific mechanism.
Unique structure: The structural design of the stepping beam is unique, and the fixed saddle of the saddle-shaped welding structure is arranged on it. Each fixed saddle is arranged at a certain distance so that the moving beam can move the steel coil from one fixed saddle to the next fixed saddle during operation. This design enables the stepper beam to achieve a smooth and accurate step movement when transporting steel coils.
High transportation efficiency: The stepping beam realizes the stepping transport of the steel coil on the fixed saddle through the periodic movement of the moving beam "rising - advancing - falling - retreating". This mode of transportation enables the stepper beam to complete the transportation of a large number of steel coils in a short time, improving the production efficiency. At the same time, the stepping beam is also equipped with a lifting mechanism and a transverse mechanism, so that it can realize the transportation of the steel coil and the horizontal coil according to the different production process requirements.
Strong adaptability: the movement mode of the stepping beam is divided into translation movement and lifting movement, in which the translation movement is driven by the translation hydraulic cylinder device. According to the type of lifting mechanism, stepping beam can be divided into vertical type, connecting rod type, slope type and eccentric wheel type. These different types of stepper beams have different characteristics and application scenarios, and can meet the needs of different production processes.
High safety: When the steel coil is transported, the stepper beam is supported and fixed by a fixed saddle, which ensures the stability of the steel coil during transportation. At the same time, the stepping beam is also equipped with perfect safety protection devices, such as emergency stopping device, overload protection device, etc., which can stop in time when there is an abnormal situation to ensure the safety of equipment and personnel.
The working principle of the stepping beam is mainly based on electromagnetic principle and hydraulic transmission technology. The stepping beam is composed of a motor, a control circuit and a guide rail. When the motor is driven by a current, the stator inside the motor generates a magnetic field, and the stator's magnetic field interacts with the permanent magnet on the rotor inside the stepper beam. By changing the direction and magnitude of the current, the change of the stator magnetic field can be controlled, and then the momentum and direction of the stepper beam can be controlled. At the same time, the stepping beam is also equipped with the transverse hydraulic cylinder and the lifting hydraulic cylinder, and the horizontal movement and lifting movement of the stepping beam are realized through the hydraulic transmission technology. Stepper beams have a wide range of applications, not limited to the steel industry. In precision instruments and automation equipment, stepping beam also has an important application. For example, stepper beams can be used to control the position and speed of CNC machine tools, printing presses, textile machinery, vending machines and other equipment. In addition, the stepper beam can also be used to control the focal length of the camera and the direction of the lens.
