Thermal power forging is an important component in thermal power generation equipment, its quality and performance directly affect the efficiency and safety of thermal power generation equipment. In order to ensure the quality of thermal power forgings, strict quality control measures must be taken in the manufacturing process. This paper will introduce the quality control measures in the manufacturing process of thermal power forgings from the aspects of raw material purchase, storage, processing and testing.
Quality control measures
Raw material purchasing process
In the procurement of raw materials, we should select reputable suppliers and ensure that the purchased raw materials meet the relevant standards and requirements. In addition, strict quality inspection should be carried out on raw materials entering the factory, including chemical composition analysis, mechanical properties testing, etc., to ensure that the quality of raw materials meets the requirements.
Storage link
In the storage process, we should ensure that the storage conditions of raw materials and semi-finished products meet the requirements to avoid moisture, rust, deformation and other problems. At the same time, should establish a strict inventory management system, regular inventory inventory and inspection, timely detection and treatment of quality problems.
Processing link
In the processing process, the following measures should be taken:
(1) Formulate strict processing technology and operating procedures to ensure the standardization and consistency of the processing process;
(2) Regular maintenance and maintenance of the processing equipment to ensure the stability and reliability of the equipment;
(3) Strict control of key links in the processing process, such as forging, heat treatment, machining, etc., to ensure the consistency of product quality;
(4) Timely processing and analysis of waste products and unqualified products generated in the processing process, to find out the causes and take measures to improve.
Detection link
In the testing process, the following measures should be taken:
(1) Formulate strict testing standards and operating procedures to ensure the standardization and consistency of the testing process;
(2) Adopt advanced testing equipment and means, such as flaw detection, mechanical property testing, chemical analysis, etc., to improve the accuracy and reliability of testing;
(3) Record and analyze the test data in detail, find and deal with quality problems in time;
(4) To trace and deal with nonconforming products, find out the reasons and take measures to improve.
In the manufacturing process of thermal power forgings, there are several key control points that need special attention:
Forging link: Parameters such as forging temperature, forging speed and forging strength should be controlled to ensure that the forging has good organizational structure and performance stability.
Heat treatment: Parameters such as heating temperature, holding time and cooling speed should be controlled to ensure that the forgings have the required mechanical properties and corrosion resistance.
Machining link: Parameters such as cutting speed, feed rate and cutting depth should be controlled to ensure that the forging has the required dimensional accuracy and surface quality.
For these critical control points, the following measures can be taken to control:
Formulate strict process and operating procedures, train and assess operators to ensure that they master the correct operating methods;
Using advanced testing equipment and means, real-time monitoring and data acquisition of critical control points, timely detection and treatment of quality problems;
Establish quality files, record and analyze data of critical control points, identify problems and take measures to improve them.
In order to ensure the effective implementation of quality control measures in the manufacturing process of thermal power forgings, a perfect quality control system must be established. The system should include the following aspects:
Quality management system: Establish ISO 9001 quality management system or other equivalent quality management system to ensure the standardization and effectiveness of quality management work.
Quality inspection system: Establish a complete quality inspection system, including raw material inspection, process inspection and final inspection, etc., to ensure the stability and consistency of product quality.
Quality improvement system: Establish a quality improvement system, trace and analyze quality problems, find out the reasons and take measures to improve, and constantly improve product quality.
Quality training system: Establish a quality training system to train and assess operators, improve their quality awareness and skill level, and ensure that product quality is effectively controlled.
Quality control measures in the manufacturing process of thermal power forgings are important means to ensure product quality. By adopting strict quality control measures, we can ensure that the thermal power forging has stable quality and performance, so as to improve the operating efficiency and safety of thermal power generation equipment. Therefore, in the manufacturing process of thermal power forgings, we must pay attention to quality control work, establish a perfect quality control system, and strengthen the monitoring and management of key control points. Only in this way can the normal operation and safety of thermal power generation equipment be guaranteed.
