The countdown to the 2022 Qatar World Cup, which fans have been looking forward to, has entered. Although the Chinese men's football team missed the competition, "Made in China" has played an important role in this world competition. From small souvenirs and daily necessities to large buses and stad
By improving the bearing clearance measurement method and method of the slitting machine, the machining accuracy is ensured, the operation is more convenient, and the machining production efficiency is improved. Through the functional analysis of the practice of the high-speed precision carbon steel
Seven maintenances make the slitting machine look brand new as a wholeIn the usual industrial production, the equipment is the same as the human being. After long-term work, it must be rested and maintained. This is the case with slitting machines. After long-term work, basic maintenance must be car
The appearance of gaps refers to the phenomenon that the welds are not bonded together. The length of the gaps is generally more than a few centimeters or even longer. The main reasons are as follows:(1) Pass wearAs the extrusion roll hole pattern wears, the hole pattern (R) size gradually becomes l
Sand-hole pipes are also a kind of quality accident caused by weld leakage, but their gaps are very small, some of them cannot be directly observed by human eyes, and must be found through testing equipment, so we call this kind of pipes sand-hole pipes. The main reasons for sand hole pipes are as f
(1) The hole type does not matchThere are two-roller, three-roller and four-roller weld seam extrusion structures. As long as the combined hole shapes do not match, it is easy to cause scratches on the surface of the tube blank, especially the two-roller structure.There are many factors that cause t
