Hot die forging is an important metal forming process, which is widely used in various fields. In the process of hot die forging, heating is a very key link, which directly affects the quality and production efficiency of forging. However, different heating methods differ greatly in terms of energy consumption and efficiency. Therefore, it is of great significance to study the influence of hot die forging heating method on energy saving and efficiency for promoting the sustainable development of hot die forging process.
Analysis of heating method and energy consumption and efficiency of hot die forging
Flame heating: Flame heating is a traditional heating method that uses the flame generated by gas or oil to heat the metal blank. Although the flame heating equipment is simple and low-cost, its energy consumption is high, the heating efficiency is relatively low, and the heating uniformity is poor.
Electric induction heating: electric induction heating uses the principle of electromagnetic induction to generate eddy currents inside the metal billet, and achieves heating through the Joule thermal effect of eddy currents. Induction heating has the advantages of fast heating speed, high efficiency and low energy consumption, but the equipment cost is relatively high.
Laser heating: Laser heating is a new heating method that uses a high energy laser beam to locally heat the metal billet instantaneously. Laser heating has the advantages of extremely fast heating speed and high precision, but the equipment cost is expensive, and the heating efficiency is relatively low for large forgings.
The choice of heating method directly affects the energy consumption, efficiency and product quality of hot die forging production. In order to reduce energy consumption and improve efficiency, the following optimization suggestions can be taken:
According to product demand and production scale, reasonable selection of heating methods. For small, high-precision forgings, electric induction heating or laser heating can be used; For large forgings, flame heating or improved induction heating can be considered.
The existing flame heating equipment is reformed and upgraded, and advanced combustion technology and energy-saving equipment are adopted to improve the efficiency and uniformity of flame heating and reduce energy consumption.
Strengthen production management, rationally arrange production plan and forging heating sequence, reduce no-load time and standby energy consumption of heating equipment.
The heating method of hot die forging has significant influence on energy saving and efficiency. Choosing the right heating method can not only reduce energy consumption, improve production efficiency, but also improve the quality of forgings and promote industrial development. In order to realize the sustainable development of hot die forging, it is necessary to comprehensively consider many factors such as product demand, production scale, equipment cost, and choose the most suitable heating method and continue to optimize it. In the future research, we can further focus on the development and application of new heating technology to promote the development of hot die forging process to a more efficient and energy-saving direction.
