As the key parts of the ship, the manufacturing process and quality control of Marine rudder forging are particularly important. As an advanced forging technology, warm forming technology can achieve accurate plastic deformation at low temperature, and is widely used in the production of Marine rudder forgings. In this paper, the warm forming technology of Marine rudder forging is discussed in detail.
Thermoforming technology refers to a process method of plastic deformation under conditions lower than the recrystallization temperature of the material. Compared with traditional hot forming and cold forming, warm forming technology has more mild temperature conditions and less deformation resistance, can achieve more accurate plastic deformation, and less damage to the material.
Warm forming technology for forging parts of Marine rudder system
Preheating: The material is heated to the appropriate temperature to make it have a certain plasticity and good processing properties. The preheating temperature should be lower than the recrystallization temperature of the material to avoid grain growth and material embrittlement.
Forming: The preheated material is put into the mold and plastic deformation occurs by applying external force. In the forming process, the deformation speed and deformation amount should be controlled to avoid material cracking and grain breakage.
Tempering: After forming, the forgings are properly tempered to eliminate internal stress and improve the mechanical properties of the material. The tempering temperature should be lower than the recrystallization temperature of the material to maintain good plasticity of the material.
Application advantage of warm forming technology in forging of Marine rudder system
Improve product quality: Warm forming technology can achieve more accurate plastic deformation, reduce the internal stress and residual stress of forgings, and improve the dimensional accuracy and mechanical properties of products. This helps to improve product quality and reliability and reduce the rate of product rejection.
Reduce production costs: Warm forming technology has mild temperature conditions and small deformation resistance, which can reduce energy consumption and equipment costs. In addition, the technology can reduce production cycles and labor costs, and improve production efficiency.
Broaden the application range of materials: Warm forming technology is suitable for a variety of metal materials, including high-strength steel, stainless steel and so on. This provides a wider range of options for the production of Marine rudder forgings to meet the needs of different ship manufacturing.
Improved material utilization: Warm forming technology enables accurate plastic deformation, reducing machining allowance and material waste. This helps to improve the utilization of materials and reduce production costs.
Environmental protection and energy saving: The temperature conditions of warm forming technology are lower, which can reduce energy consumption and reduce environmental pollution. In addition, the technology is able to reduce waste and waste generation, in line with the requirements of green manufacturing and sustainable development.
Warm forming technology has significant advantages and application prospects in the production of Marine rudder system forgings. By using the warm forming technology, the product quality can be improved, the production cost can be reduced, the application range of materials can be expanded, the utilization rate of materials can be improved, and the environmental protection and energy saving can be achieved. In the future, with the continuous development and improvement of warm forming technology, its application in the field of shipbuilding will be more extensive and in-depth. At the same time, combined with other advanced manufacturing technology and intelligent means, warm forming technology is expected to play a greater role in the production of Marine rudder forgings, and promote the innovation and development of shipbuilding industry.
