Cause Of Fracture Of Mattress Carbon Spring Steel Wire

Cause of fracture of mattress Carbon Spring Steel Wire
In addition to some of the external factors, there are impurities and other factors caused by the fracture.
1, mattress Carbon Spring Steel Wire in the presence of non-metallic inclusions, undermine the continuity of the organization, played a role in the micro-cracks. When subjected to external forces, additional stress concentration is first generated at the top of the inclusions. When the stress concentration reaches a certain size will make the carbide cracking, or in the carbide and the substrate at the junction of cracks. When the crack reaches the unsteady state size, the ground instantaneous fracture.
1, mattress Carbon Spring Steel Wire on the elimination of cracks, subcutaneous bubbles and non-metallic inclusions will be caused by cracks in the wire rod defects, and other billet heating process will also cause the finished product cracks.
2, the process of storage and transportation can cause mattress Carbon Spring Steel Wire surface after the rapid cooling, resulting in the formation of hardened layer surface, resulting in finished surface cracks.
To take this control measures:
1, to prevent the mattress Carbon Spring Steel Wire surface cracks, subcutaneous bubbles and non-metallic inclusions, steelmaking measures are the use of weak cold system, large casting machine arc radius, mold powder casting, a reasonable mold vibration , Mold electromagnetic stirring, accurate mold level control and other aspects of technology. While ensuring that the quality of copper in the Carbon Spring Steel Wire is controlled below 0.10% and the mass fraction of tin and sulfur in the steel is reduced as much as possible.
2, rolling for the control of the ear, folding, need to strengthen the head and tail shear of the standardized operation to ensure the representation of the aging sample; the same time, in order to eliminate the mattress Carbon Spring Steel Wire surface crack, Heating rate and temperature range of heating section.
3, storage and transportation processes to increase the simple packaging, reduce mechanical losses.
There are a number of reasons for the breakout of Carbon Spring Steel Wire, which is a solution to these reasons. We hope that the above measures will help you.
Carbon Spring Steel Wire will have a certain life limit, so if you want to use before and after the quality can be guaranteed, regular maintenance is necessary, if not timely maintenance, it may cause product quality Of the decline, then how to maintain it? Hope that through the following, you can help in the future use.
1. Pickling General use of hydrochloric acid at room temperature for chemical reactions, pickling after the Carbon Spring Steel Wire surface is more beautiful, pickled after cleaning the surface of the acid, rinse with plenty of water.
2. Pickling after the need for phosphating, phosphating is divided into high temperature phosphating and medium temperature phosphating, high temperature flexibility and high cost, energy consumption, but the performance is more stable, Carbon Spring Steel Wire higher quality, medium temperature phosphating cheap , Quality is not high temperature phosphating high quality. Uniformly fine phosphating layer is an important indicator of Carbon Spring Steel Wire phosphating, high-quality phosphating, to ensure that Carbon Spring Steel Wire acid, alkali, corrosion, etc., to improve the life of Carbon Spring Steel Wire is high Quality Carbon Spring Steel Wire is an important indicator of measurement.
The maintenance of Carbon Spring Steel Wire also directly determines whether it will affect its useful life in the future. It may cause problems such as corrosion, broken wire, wear and tear, but if the treatment is timely, these problems can be avoided. It depends on the user is not really determined to maintain.
