The development of Oil-tempered spring steel wire

Oil-tempered spring steel wire production engineering originated in The european countries and then multiply to Japan. In the early 1970's our nation began to investigation our own oil-tempered spring steel wire creation technology.

Once the reform along with opening up, particularly in recent years, using the rapid development of automotive field, motorcycle business, diesel website industry, machines industry, china and taiwan has little by little become the planet's processing platform of oil-tempered spring steel wire. A temptation constitutes a variety of oil-tempered spring steel wire makers.

During the process connected with research oil-tempered spring steel wire technological know-how, we predominantly refer to specialized standards along with technology concepts of Sweden in addition to Japan. But in the early levels of the approach technology we now have met lots of problems. Through to the late 80s, early 90s, oil-tempered spring steel wire production method was basically stable. Along the way, some challenges have been sorted out, such as the problem of brittle fracture associated with steel, decarburization troubles, crack difficulties, the problem associated with uneven sizing, dimensional precision problems.

But the problems with oil-tempered spring steel wire have been fundamentally solved, soon after summing-up, these problems continue to keep affect the effectiveness. We must improve knowledge of essential oil ¡§C tempered spring aluminum wire in addition to increase the expense of know-how and devices, to ensure item quality to an alternative level. In any other case we can solely wandering in the field of low-end spring merchandise.
