With the development of science and technology, steel rolling mills are constantly being upgraded and improved. The main function of a steel rolling mill is to deform and achieve the desired shape and size by applying pressure to the metal. This process involves complex physical and chemical reactions that require precise control and adjustment. Today, we will discuss the issues that need to be paid attention to and the areas that need to be adjusted during the production and rolling process of the rolling mill.
The following aspects need to be paid attention to during the production process of the steel rolling mill:
Operators should be familiar with the operating procedures and operate in strict accordance with the regulations. When the equipment is running, non-operators are prohibited from entering the operating area to avoid danger.
Before starting the machine, check whether the equipment and tools are defective and whether the lubrication of all parts is good. If problems or abnormalities are found in the equipment, it should be stopped and inspected in time to ensure the normal operation of the equipment.
According to the variety, specifications, and production process requirements of steel products, the rolling parameters of the rolling mill, such as roll gap, rolling speed, rolling temperature, etc., are reasonably adjusted to ensure product quality and production efficiency.
During the rolling process, pay close attention to the quality of the steel, such as surface quality, dimensional accuracy, etc. If quality problems are found, process parameters should be adjusted or the machine shut down in time to ensure that product quality meets requirements.
Optimize the production process and operating methods to reduce the energy consumption of the rolling mill. For example, reasonably adjust rolling speed, reduce no-load operation time, improve equipment efficiency, etc., to reduce production costs.
Perform regular maintenance on the rolling mill, replace seriously worn parts, and keep the equipment in good condition. At the same time, attention should be paid to the lubrication, cooling, and other auxiliary systems of the equipment to ensure their normal operation.
During the production process, we must comply with environmental protection regulations and reduce the emission of waste gas, waste water, noise, and other pollutants. Take effective environmental protection measures, such as installing dust removal equipment, noise reduction facilities, etc., to protect the environment and employee health.
Detailed records of various parameters and operations during the production process for subsequent analysis and improvement. If abnormal conditions or quality problems are discovered, they should be reported to superiors promptly and assisted in handling them.
During the rolling process of the steel rolling mill, equipment adjustment is crucial, involving many aspects such as product quality and production efficiency. The following are the main aspects of equipment adjustment:
Upper roller adjustment device: Realize the pressing or lifting of the upper roller. Common adjustment types include manual press-down, electric press-down, and hydraulic press-down.
Lower roller adjustment device: Realize the lifting or lowering of the lower roller. The commonly used forms include the gear screw lower adjustment structure and the inclined block screw lower adjustment structure.
Ensure rolling line stability and accuracy. This involves adjusting the horizontal, vertical, and axial positions of the rolls to ensure that the rolled pieces are rolled according to the established rolling line.
According to the specifications and process requirements of the rolled piece, the rolling force is adjusted to ensure the dimensional accuracy and surface quality of the rolled piece.
According to the specifications, steel type, and process requirements of the rolled products, the rolling speed is reasonably adjusted to be efficient.
Control the flow and temperature of cooling water to ensure temperature control of the rolled piece during the rolling process.
Ensure the supply and pressure of lubricating oil are stable. Reduce the friction between the roll and the rolled piece. It improves the rolling efficiency.
Advanced auto control technology monitors and adjusts the rolling mill in real time to improve the stability and controllability of the production process.
The equipment adjustment of the steel rolling mill during the rolling process involves many aspects. It is necessary to comprehensively consider factors such as product quality, production efficiency, energy consumption, etc. Then, we make reasonable adjustments and optimizations. At the same time, operators should have rich experience and skills. Thus they can be able to flexibly respond to various changes and challenges according to actual conditions.
