Carbide liner bushing is an alloy material made of hard compound of refractory metal and bonding metal through powder metallurgy process, also known as tungsten steel bushing. Because cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, it basically remains stable even at a high temperature of 500 ° C. change, and still have high hardness at 1000 °C.
Carbide bushings generally also have the characteristics of small deformation and high precision.
Carbide bushings are mainly used for petting and aspect and stretching. Its main function is that the bushing is a type of component that protects the equipment. The use of the bushing can effectively reduce the wear between the punch or the bearing and the equipment, and achieve a guiding role. In terms of stamping dies, cemented carbide bushings are widely used because of their wear resistance and good finish, and do not need to be replaced frequently, so as to achieve a higher utilization rate of equipment and personnel.
In terms of stretching of cemented carbide bushings, it is mainly the stretching of some copper parts and stainless steel parts. Due to the high frequency of use, it is easy to heat up and cause wear of the bushing, so that the punching needle shifts, the size error of the product, and the product size error. poor appearance.
With the increase of oil extraction, the oil on the shallow surface decreases. In order to ensure the usage amount, people gradually develop to large deep wells and highly deviated wells, but the difficulty of oil extraction is gradually increasing. Wear resistance, corrosion resistance, or impact resistance, etc.
As a wear-resistant component in petroleum machinery wells, cemented carbide bushings have the properties of high hardness, good wear resistance and high finish. They have been widely used in modern society and meet the needs of daily use and special performance. Some enterprises use spray welding process to improve the durability and service life of cemented carbide bushings.
The cemented carbide bushings produced by our company provide the most suitable production solutions according to the product performance, grade and size required by customers.
