The free forging equipment commonly used by forging plants are: air hammer, air steam hammer and hydraulic press forging equipment. The nominal parameters of the air hammer are 65kg, 100kg, 150kg, 250kg, 400kg, 560kg and 750kg. The air hammer is simple in structure, easy to operate, easy to maintain Read More

Heating before forging is an indispensable part of the whole forging process, which has a direct impact on improving forging productivity, ensuring forging quality, saving energy consumption and reducing product cost. The purpose and requirements of forging heating are as follows:1. Heating purposeI Read More

During the production of forgings, in addition to ensuring the required shape and size of forgings, the performance requirements of forgings during use must also be met, which mainly include: strength index, plasticity index, impact toughness, fatigue strength, initial fracture degree, stress corros Read More

The purpose of economic analysis of forging process is to explore the best technical scheme and pursue the maximum economic effect. In any production process, it is not only necessary to formulate the process, determine the process parameters and process equipment, but also to discuss the economic e Read More

The process way to improve the plasticity of forgings and reduce deformation resistance In order to facilitate the flow forming of metal blanks, reasonable measures can be taken to reduce deformation resistance and save equipment energy during forging, the following methods are generally used to ach Read More

The design of precision die forging is the same as that of ordinary die forging, and the precision forging drawing is prepared according to the product part drawing. It is the main basis for formulating precision forging process, designing precision forging die, manufacturing and acceptance of forgi Read More

Forging is an article in which metal is pressed to shape the required shape or suitable compression force through plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process creates a refined granular structure and improves the physical properties of the Read More

The forging of large aluminum forgings not only needs to meet the required part shape and size, but also is important to break the as cast structure, refine the grain, uniform structure, forging shrinkage cavity, air hole, shrinkage porosity and other defects, so as to improve the internal quality o Read More

The purpose of heat treatment for large forgings after forging is to refine the coarse grains caused in the forging process, eliminate work hardening and residual stress, reduce hardness, improve cutting performance, prevent white spots from forming inside the forgings, ensure the required metal str Read More

The cooling modes of large forgings mainly include water cooling (including water spray cooling), oil cooling, air cooling (natural air cooling and air blast cooling), gap cooling (water air, water oil, oil air) and spray cooling. The commonly used quenching media for large forgings are water, oil a Read More

High-temperature alloys are iron, nickel and cobalt-based metal materials that can work for a long time at temperatures above 600°C and under certain stresses, with excellent high-temperature strength, good resistance to oxidation and thermal corrosion, good fatigue properties, fracture toughness an Read More

Traditionally, high-temperature alloy materials can be classified in three ways: by matrix element type, alloy strengthening type, and material forming method.1、According to the type of matrix elements(1) Iron-based high-temperature alloysIron-based high-temperature alloy can also be called heat-res Read More
