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?
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.
What are the main inspection methods for forgings?
The main inspection methods of Dalian forgings include chemical composition analysis, mechanical property test, low magnification inspection, metallographic high magnification inspection and nondestructive testing.
What are the advantages of forging heat quenching of Dalian forgings?
Dalian forging heat quenching can improve the properties of forgings.Forging heat quenching can significantly improve the strength and hardness on the premise of maintaining plasticity and toughness.
