Performance requirements for forgings processed by forging

In forging production, in addition to ensuring the required shape and size of forgings, it must also meet the performance requirements of forgings in the process of use, which mainly include: strength index, plasticity index, impact toughness, fatigue strength, initial fracture and stress corrosion resistance. For parts working at high temperature, there are also high-temperature instantaneous tensile properties, durability and thermal fatigue properties.

What are the advantages of forgings and why should forgings be selected?

Dalian forgings are widely used in building materials industry. Conceptually, a forging is a metal that exerts pressure to create a desired shape or appropriate compression through plastic deformation.

What are the analysis methods of Dalian forging quality?

2. find out the quality problems, mainly to find out the causes, find out the defect parts and macro characteristics of forgings, and preliminarily judge whether the defects are caused by raw materials or forging process.

Rescue measures for loose connection between stainless steel piston rod and piston

Before the use of the hydraulic cylinder, the stainless steel piston rod and piston must be connected. During the use, due to some reasons, the stainless steel piston rod and piston may become loose.

Precautions for equipment installation of piston rod

Piston rod is often used in almost all mechanical equipment, so we must pay attention to its installation. Otherwise, if the installation is incorrect, the equipment may not operate normally. In order to effectively improve the assembly quality of the equipment for better work.

What are the disadvantages of flame surface quenching of Dalian forgings?

The method of spraying the high-temperature flame generated by the mixing of combustible gas and oxygen onto the surface of the forging to quickly heat it to the quenching temperature, and then spraying a certain quenching medium on the heating surface for quenching and cooling is called flame surface quenching method.
