With the continuous growth of global energy demand, power plants have put forward higher requirements for the performance of materials operating under high temperature and high pressure environments. As the core material of key components of thermal power plants, the forming process of heat-resistant steel directly affects the reliability, life and energy efficiency of equipment. In recent years, the forming technology of heat-resistant steel has been continuously innovated, providing a solid guarantee for the efficient operation of power plant equipment.
The forming process of heat-resistant steel mainly includes forging, rolling, welding and precision casting. Among them, the forging process applies pressure to the metal billet at high temperature to optimize its microstructure, thereby improving the creep resistance and high temperature strength of the material. Modern forging technology uses a combination of computer simulation and automatic control to significantly improve the consistency and qualified rate of products. The rolling process refines the grains through multiple rolling passes to further enhance the toughness and high temperature corrosion resistance of the material.
Welding technology is another key link in the forming of heat-resistant steel. Since heat-resistant steel usually contains a high proportion of alloy elements, cracks and performance degradation are prone to occur during welding. At present, advanced laser welding and plasma arc welding technologies have been widely used in the connection of heat-resistant steel parts, effectively reducing the heat-affected zone and improving the durability of welded joints. In addition, the precision casting process can produce high-precision parts with complex shapes by controlling the cooling rate and mold design, meeting the needs of power plants for special-shaped components.
In the future, the heat-resistant steel forming process will develop in the direction of intelligence and greening. The introduction of artificial intelligence and big data technology will further enhance the process optimization capabilities, and low-energy consumption and low-emission forming technology will also become a research and development focus. With the promotion of ultra-supercritical units and nuclear power generation technology, the market demand for heat-resistant steel will continue to expand, and the innovation of its forming process will provide important support for the upgrading of power plant equipment.
The progress of heat-resistant steel forming technology has not only promoted the improvement of power plant equipment performance, but also injected new impetus into the sustainable development of the global energy industry.
