As the core component of hydropower power station, the quality control of hydropower forging is very important in its manufacturing process. This paper will introduce the quality control in the manufacturing process of hydropower forgings in detail, including quality control overview, quality control process and quality control measures.
I. Overview of quality control
The quality control in the manufacturing process of hydropower forgings is to ensure the quality, performance and reliability of products to meet the safe and stable operation needs of hydroelectric power stations. Quality control includes the management of raw materials, design, manufacturing process, process control and product inspection. By establishing a strict quality control system, it can improve production efficiency, reduce costs, reduce quality accidents and reduce maintenance costs.
- Quality control process
Design control
In the design stage, we should fully consider the selection of raw materials, manufacturing process and product performance requirements. Carry out sufficient technical research and demonstration, formulate detailed design scheme, and form design document. In the design process, it is necessary to follow the relevant national and industry standards to ensure the rationality and standardization of the design.
Manufacturing process planning
According to the design requirements, make a reasonable manufacturing process plan. Clarify the technical requirements, process flow, operating procedures and quality control standards of each production link. In view of the difficulties and key points in the manufacturing process, formulate countermeasures in advance to ensure the smooth progress of the manufacturing process.
Process control
In the production process, the process parameters and technical requirements should be strictly controlled. Strengthen the inspection of raw materials, semi-finished products and finished products, and establish a sound quality record and statistical system. Analyze and deal with the problems in the production process in time to ensure that the problems are effectively solved and prevent the occurrence of quality accidents.
Product testing
In the testing stage of the finished product, strict testing should be carried out in accordance with the relevant national and industry standards. The test contents include appearance quality, dimensional accuracy, material properties and functional tests. Ensure that products meet design requirements and performance, rework or scrap unqualified products, and prevent bad products from entering the market.
Third, quality control measures
Enhanced forging process
Forging process is an important link in the manufacturing process of hydropower forgings, which directly affects the quality and reliability of products. Therefore, it is necessary to strengthen the control of the forging process, including strict control of the heating temperature, forging ratio, cooling speed and other parameters, to ensure that the product has good mechanical properties and processing properties.
Strictly control the heating temperature
The heating temperature has a great influence on the mechanical properties and metallographic structure of hydroelectric forgings. If the heating temperature is too high, it will lead to quality problems such as coarse grain, oxidation and overburning. If the heating temperature is too low, it will lead to a decline in the mechanical properties of the product. Therefore, it is necessary to strictly control the heating temperature to ensure that it is within the specified range.
Choose high quality raw materials
The quality of raw materials directly affects the quality and performance of hydropower forgings. Therefore, it is necessary to choose suppliers with good reputation and quality assurance, and choose high-quality raw materials that meet the design requirements. At the same time, the inspection and quality control of raw materials should be strengthened in the production process to ensure that the quality of raw materials meets the requirements.
Improve the quality and skill level of employees
Staff is an important factor in the production process, which directly affects the quality of products. Therefore, it is necessary to strengthen the training and education of employees to improve their quality awareness and skill level. Establish a sound incentive mechanism to encourage employees to actively participate in quality improvement activities and improve the quality control level in the production process.
We will strengthen the construction of the quality management system
Establish a sound quality management system, including document control, quality records, nonconforming product control and corrective measures. Through strengthening the construction of quality management system, to ensure the effective implementation and continuous improvement of quality control in the manufacturing process of hydropower forgings.
Iv. Conclusion
The quality control of hydropower forging is one of the key links to ensure the safe and stable operation of hydropower station. This paper introduces the quality control in the manufacturing process of hydropower forgings from the aspects of quality control overview, quality control flow and quality control measures. By establishing strict quality control system, strengthening forging process and selecting high-quality raw materials, the quality and reliability of hydropower forgings can be effectively improved, and quality accidents and maintenance costs can be reduced. In the future production process, it is also necessary to continuously strengthen the construction of quality management system and technological innovation, and constantly improve the overall level of the hydropower forging industry.
