Thermal power forging is an important component in thermal power generation industry, its quality and performance directly affect the operating efficiency and safety of thermal power generation equipment. In order to meet the higher requirements of use, the production process of thermal power forgings must strictly follow the quality control standards. This paper will analyze and discuss the quality control standard in the production process of thermal power forging.
Quality control standard
Quality requirement
The quality requirements of thermal power forging mainly include chemical composition, mechanical properties, dimensional accuracy, surface quality and so on. Chemical composition requirements meet the relevant standards and regulations, mechanical properties requirements meet the design and use requirements, dimensional accuracy requirements meet the drawing and process requirements, surface quality requirements without cracks, burrs, oxide and other defects.
Production process
The production process of thermal power forgings mainly includes raw material inspection, heating, forging, heat treatment, processing, inspection and other links. In the production process, it is necessary to operate in strict accordance with the process flow to ensure the quality control of each link.
Inspection test
In the production process of thermal power forgings, many inspections and tests must be carried out to ensure that product quality meets the requirements. The contents of inspection and testing include chemical composition analysis, mechanical property testing, dimensional measurement, surface inspection, etc. The results of inspections and tests must be recorded and archived for traceability and analysis.
Quality control measures
Production management
Strengthening production management is one of the key measures to ensure the quality of thermal power forgings. Develop a sound quality management system, clarify the job responsibilities and work flow, strengthen the monitoring and management of the production process, and ensure the quality control of each link.
Technology research and development
Strengthening technology research and development is one of the important measures to improve the quality of thermal power forging. Carry out research and application of new materials and new processes, optimize production processes and equipment, and improve production efficiency and product quality.
Quality inspection
Strengthening quality inspection is one of the key measures to ensure the quality of thermal power forgings. Establish a sound quality inspection system, equipped with advanced testing equipment and instruments, strengthen the training and management of testing personnel, to ensure the accuracy and reliability of test results.
Quality detection method
Visual inspection
Appearance inspection is one of the basic methods for quality inspection of thermal power forgings. Inspect the surface of the forging with a visual or magnifying glass to see if there are cracks, burrs, oxide and other defects.
Dimensional measurement
Dimension measurement is one of the important methods for quality inspection of thermal power forgings. Calipers, micrometers and other measuring tools are used to measure the size of the forging to check whether it meets the drawing and process requirements.
Chemical composition analysis
Chemical composition analysis is one of the key methods for quality inspection of thermal power forgings. The chemical composition of forgings is analyzed by means of spectral analysis and chemical analysis to check whether it meets relevant standards and regulations.
Physical property test
Physical property testing is one of the important methods for quality testing of thermal power forgings. The mechanical properties of forgings are tested by means of tensile test and impact test to check whether they meet the design and use requirements.
Taking a thermal power forging production enterprise as an example, the enterprise adopts strict quality control standards and measures in the production process to ensure the stability and reliability of product quality. In the production process, the enterprise adopts advanced forging equipment and technology to improve production efficiency and product quality. At the same time, the enterprise has established a perfect quality management system and testing system, strengthened the monitoring and management of the production process, and ensured the quality control of each link. In a quality spot check, all the thermal power forgings produced by the enterprise were qualified, and were highly praised by customers.
The quality control standard in the production process of thermal power forging is one of the important measures to ensure product quality. In the production process must be strictly in accordance with the process of operation, strengthen production management, technology research and development and quality testing and other aspects of the work to ensure the quality control of each link. Through the use of advanced quality testing methods and means, can effectively improve product quality and stability, enhance the core competitiveness of enterprises and market share. In the future, with the continuous development of science and technology and the adjustment of energy structure, the quality control standards in the production process of thermal power forgings will be continuously improved and improved.
