How To Solve The Shaped Spring Steel Wire At The Depression

How to solve the Shaped Spring Steel Wire at the depression
Shaped Spring Steel Wire in the production will encounter all kinds of problems, one of which is concave depression at the slow, affecting the production process, how should we solve it.
Shaped Spring Steel Wire's surface is relatively smooth, but also because the processing used in the high-pressure phosphorus removal process, so you can ensure that the flat steel surface smooth, Shaped Spring Steel Wire size is also more accurate. In fact, want to solve the Shandong Shaped Spring Steel Wire depression on the slow situation, we must first find out where the main reason is that the current is small, the bath contains lead composition, the temperature is relatively high, less brightener It will cause this phenomenon, you want to solve this situation, it is recommended that you increase the current, add potassium chloride, zinc powder can also be used to deal with, do a good job cooling, add a brightener on it.
Solve the Shaped Spring Steel Wire Slippery method is simple to operate, it is important that we should master some skills.
There are two main forms of longitudinal Shaped Spring Steel Wire: one is parallel to the mattress Shaped Spring Steel Wire axial linear crack; the other is along the mattress Shaped Spring Steel Wire axial surface curve Shaped curve.
The mattress Shaped Spring Steel Wire was made into a transverse metallographic sample, and it was observed that the curve-type longitudinal shear was actually folded, and the macroscopic shape was similar to the zigzag fold at high magnification. Its main features are cracks and mattress Shaped Spring Steel Wire surface oblique, the edge of the general existence of a serious decarburization, often accompanied by oxide inclusions. A large number of test results show that the depth of folding with the steel, furnace number, origin, specifications vary widely, generally between 0.08-0.45mm, a few serious up to 1mm or more. Some of the wire rod is only one fold, and some are up to 7,8 fold, or even more. The reason is due to the ingot or steel surface uneven and sharp edges and corners, etc., in the rolling process superimposed on the steel, or the ear in the subsequent rolling from the superposition.
In the actual production of mattress Shaped Spring Steel Wire, there may be two or more defects on the surface of the Shaped Spring Steel Wire, causing a number of cracks in different shades.
Mattress Shaped Spring Steel Wire should be more careful if it is strong and durable, but improperly stored or improperly shipped.
1, in the mattress Shaped Spring Steel Wire loading and unloading, it is best hanging net, non-metallic rope and other soft cable tools, do not recommend the use of scratches its surface chains, wire rope and other tools. But also in the handling, handling pipes can not throw throw, rolling;
2, in the course of transport should be avoided by severe crushing or severe impact, but also to prevent the sun was sun or by oil, chemicals and other pollution;
3, as far as possible in the open air to avoid the way to store;
4, stacked when neat and orderly. And the bottom of the pipeline should be flexible bearings, such as sand, wood, etc., while the pipeline code can also be placed between the layers of the appropriate pad of wood, straw mats, etc., so as to avoid long-term storage deformation;
5, should be away from heat, oil and chemical pollution areas, and storage should be exposed to ventilation.
Store the transport mattress Shaped Spring Steel Wire during the bad problem we should try to avoid, hope that the above methods are helpful to you.
