Marine rudder forging is an important part of ship manufacturing, its quality is directly related to the safety and service life of the ship. This paper will introduce the production process and quality control of Marine rudder system forgings in detail to ensure the quality and reliability of forgings.
Production technology
Raw material preparation: Select high-quality steel as raw materials to ensure that the mechanical properties and chemical composition of the material meet the standard requirements. In the process of raw material preparation, strict inspection and quality control should be carried out to prevent unqualified materials from flowing into the production link.
Heating and forging: The raw materials are heated to the appropriate temperature and forged by forging equipment. The forging process should control the temperature, deformation and forging speed to ensure the quality and dimensional accuracy of the forging. At the same time, the forging equipment should be regularly maintained and checked to ensure the stability and reliability of the equipment.
Heat treatment: After forging is completed, heat treatment is required to eliminate internal stress and improve the mechanical properties of the material. During the heat treatment process, the temperature, time and cooling speed should be controlled to ensure that the heat treatment effect reaches the expected goal.
Processing and assembly: processing and assembly of forgings after heat treatment. Dimensional accuracy and surface quality should be ensured during processing, and the fitting accuracy and stability between components should be ensured during assembly.
Quality inspection: comprehensive quality inspection of the finished product, including appearance, size, performance and other aspects of the inspection. For unqualified products, they should be reworked or scrapped to avoid unqualified products from entering the market.
Quality control
Formulate strict quality standards and control procedures: according to national and industry standards, formulate quality standards and control procedures suitable for the actual situation of enterprises. In the production process, quality standards and control procedures should be strictly implemented to ensure the consistency and reliability of product quality.
Strengthen staff training and skill upgrading: Regularly conduct quality awareness and skill training for employees to improve their awareness of the importance of quality and their skill level. Through training, so that employees can master the process and operating procedures, reduce the impact of human factors on product quality.
Strengthen equipment maintenance and management: to ensure the stability and reliability of production equipment, regular maintenance and maintenance of equipment. The faulty equipment should be repaired or replaced in time to avoid the impact of equipment failure on product quality.
Establish a perfect quality inspection system: equipped with complete testing equipment and tools, establish a perfect quality inspection system. Through the combination of regular testing and random inspection, the product quality is comprehensively checked. At the same time, the training and management of testing personnel should be strengthened to ensure the accuracy and reliability of testing results.
Implementation of quality management system certification: actively implement quality management system certification, such as ISO 9001. Through the certification, the establishment of a sound quality management system, improve the quality management level of enterprises. At the same time, we should strengthen communication and exchange with customers, collect and process customer feedback in a timely manner, and continuously improve product quality and service level.
Through the implementation of the above measures, Marine forging manufacturers can comprehensively improve the production process and quality control level, to ensure that product quality meets the requirements of national and industry standards. This will help improve the market competitiveness of enterprises and achieve sustainable development goals.
