Typical applications of wind power fasteners |
| Update:
2011-3-29 |
| Typical applications: high voltage switching equipment, hydraulic machinery, welding equipment, tobacco machinery, microwave communications, automotive parts, air separation equipment, coal machinery, power machinery, textile and chemical fiber machinery, etc.. In thread machining errors or to repair the damaged inner screw, screw set (steel screw) can be used as a means to repair, can be quickly and effectively repair the typical applications: all kinds of important parts screw hole release after repair, such as injection molding machine template screw hole repair. Use thread sleeve thread metric vs. hole conversion is very convenient and quick. Typical application: wind power fasteners thread imported equipment or machinery spare parts because of supply problems need to be changed to metric thread. Foreign equipment manufacturing enterprises attach great importance to the heat treatment of high strength bolts, to ensure the uniformity of the organization, in order to obtain the best strength and toughness, and ensure the safety of the bolt. Domestic manufacturers have not yet been paid attention to, the general problem is the heat treatment of bolts defects, resulting in uneven tissue. Although the strength and hardness of the bolt can reach 10.9 or more performance requirements, but due to poor uniformity of the organization, a variety of reasons for early failure. Therefore, process control should be strengthened in the manufacturing process. As a series of pin mixer, wind power fastener materials re distribution, extrusion screw machine interrupt causes the material to have a return, the process of material under continuous shear, orientation, cutting, folding, stretching. The detection of high strength fasteners after heat treatment, the main test hardness and tensile strength and microstructure (qualitative detection), Rx gas analysis, 12.9 of the 100% magnetic particle fluorescence nondestructive examination of crack. But the quenching medium cooling performance measurement, the quantitative analysis of the metallographic structure, the internal defect of the parts and the hardness of the sorting is not detected. Spheroidizing annealing in the reform of materials, material annealing by induction heating, and then enter the protection of spheroidizing annealing atmosphere in furnace insulation, advanced technology, the problem can be solved very well decarburization. The wind power fasteners are widely used in wire or cast chain heat treatment quenching and tempering line. In addition to the furnace sealing performance is good, but also has advanced atmosphere, temperature and process parameters of computer control, equipment failure alarm and display and other functions. |
