What should be paid attention to when forging large forgings?

What should be paid attention to when forging large forgings? Alloy is a widely used material, and forgings are alloy components produced from alloy forging. In industries such as aerospace, ocean, and shipbuilding, the production of large machinery requires forgings with corresponding specifications, and some industries may require large forgings. Forging large forgings requires a lot of professional knowledge. Today, let’s take a look at what to pay attention to in forging large forgings. Let’s take a look together.

Forging large forgings is a complex and important task that requires attention to the following points:

1.Choose appropriate forging equipment: For the forging of large forgings, it is necessary to choose appropriate forging equipment, such as air hammers, hydraulic forging machines, hydraulic presses, etc. The power, stroke, forging force and other parameters of these equipment should be selected based on the size, shape, and material of the forging.

2.Reasonable forging process: The forging process for large forgings includes forging temperature, forging speed, forging method, etc. The forging temperature should be controlled based on the characteristics of the material and the requirements of the forging process. The forging speed should be selected based on the shape and size of the forging, and the forging methods include free forging, hot die forging, cold forging, etc.

3.Control forging defects: Large forgings are prone to defects such as wrinkles, folds, cracks, looseness, etc. during the forging process. To avoid these defects, it is necessary to strictly control the forging process, such as selecting forging equipment and tools reasonably, controlling forging temperature and speed, and avoiding rapid cooling and heating.

4.Ensure the quality of forgings: The quality of large forgings should comply with relevant standards and requirements, including size, shape, surface quality, mechanical properties, etc. During the forging process, qualified materials and forgings should be used, and the quality during the forging process should be strictly controlled, such as measuring and inspecting the size and shape of the forgings, and conducting mechanical performance tests.

5.Safety production: During the forging process of large forgings, dangerous factors such as high temperature and pressure may occur, so it is necessary to pay attention to safety production. Safety production systems and operating procedures should be formulated based on the actual situation, safety protection facilities and equipment should be set up, and safety education and training should be strengthened to ensure the safety and reliability of the forging process.

Large forging has a quite complex process. Large forging manufacturers need to choose appropriate forging equipment and reasonable forging processes, control forging defects, ensure forging quality, and most importantly, pay attention to safety during production.
