Wuxi Duorunde Steel Tube Co., Ltd (My Answer); The piercing process is a crucial step in the manufacturing process of precision seamless steel tubes. However, if abnormalities occur during the piercing process, it may negatively affect the quality and performance of the steel tube. Therefore, when abnormalities occur during the piercing process, appropriate measures need to be taken in a timely manner in order to avoid causing greater losses.
The following are some common piercing anomalies and corresponding treatment measures:
? #Automotive manufacturing ? #Military industry ? #Machining ? #Electronic equipment ? #Medical equipment ? #Engineering machinery # #? railroad locomotives ? #? Aerospace ? #? Ships ? #? Injection molding machines ? #? Die casting machines ? #? Machine tooling ? #? Diesel engines ? #? petrochemicals ? #? Power stations ? #Boiler equipment ?
Uneven wall thickness of the bristle pipe: during the piercing process, the wall thickness of the bristle pipe may be uneven. This may be caused by improper control of piercing speed and temperature, wear of rollers, etc. Treatment measures include adjusting the piercing speed and temperature, checking roll wear and replacing the roll in time.
Hair pipe diameter is too small or too large: the diameter of the hair pipe directly affects the subsequent rolling and processing. If the burr diameter is too small or too large, it may be caused by improper control of piercing speed and temperature, roll wear and other reasons. Treatment measures include adjusting the piercing speed and temperature, checking the roll wear and replacing the roll in time.
Hair pipe bending: Hair pipe may be bent during the piercing process, which may be caused by improper control of piercing speed and temperature, roll wear and other reasons. Treatment measures include adjusting the piercing speed and temperature, checking the roll wear and replacing the roll in time.
Hair pipe surface damage: Hair pipe in the piercing process may appear surface damage, which may be due to improper control of piercing speed and temperature, roll wear and other reasons. Treatment measures include adjusting the piercing speed and temperature, checking the roll wear and replacing the roll in time.
Cracks in the wall of the tube: The wall of the tube may be cracked during the piercing process, which may be caused by improper control of piercing speed and temperature, roller wear and other reasons. Treatment measures include adjusting the piercing speed and temperature, checking roll wear and replacing the roll in time.
In addition to the above common anomalies, you may also encounter some other special circumstances, such as the failure of the piercing machine, the inner wall of the tube has impurities. For these special circumstances, it is necessary to take appropriate measures to deal with the specific situation, such as timely repair or replacement of perforating machine components, strengthen the raw material rust removal, etc..
In short, in the manufacturing process of precision seamless steel tube, the piercing process is a very important step. If abnormalities occur, appropriate measures need to be taken in time to ensure that the manufactured steel tube has excellent quality and performance. At the same time, it is also necessary to strengthen the maintenance and repair of equipment to avoid unnecessary losses and waste.
