The broken hole blank of 310S stainless steel pipe is too long. In order to better improve the service life of the plug, the internal cooling circulating water is expanded. However, the spiral diameter is caused by the two significant temperatures of spiral yin-yang surface and black and red surface of the capillary. During the production and processing of cold drawing fine extruder, due to the existence of black and red capillary surface temperature and inconsistent steel strength, different steps are caused when the metal material is widened.
Generally, the blanking of seamless steel pipe is 09-1.0m. In that way, the operation of cooling circulating water in the top is smaller, which is beneficial to the surface of capillary and is not easy to be on the Yin and Yang surfaces. The feed port (inlet nozzle) at the front end of the cutting machine is clamped tightly without shaking. After the pipe blank is bitten in, the small tail of the pipe blank swings left and right. When the top is broken, it swings indefinitely, resulting in uneven wavy lines of the rough pipe, and the symmetry is accurate. Similarly, the small tail of the pipe blank will swing strongly left and right if the feed inner diameter is not large. Generally, the feed inner diameter of the pipe blank is 15mm larger, so the pipe blank is relatively stable when the pipe blank is bitten in.
For the adjustment of the centering roll, the capillary will be opened when it is close to the first centering roll, and then the capillary will enter the first centering roll, close to the centering roll and into the centering roll. In this short period of time, usually when the second centering adjusts the ejector rod to a low level, the capillary will cause instability in the operation of the ejector (when the capillary is close to the first centering roll, it will be opened and the capillary will sink down, After entering the centering roller, the capillary goes up again. In that way, it goes down one liter, and the top also goes down here. Gradually, the wall thickness of the capillary is uneven.
The blank cutting and sawing of stainless steel 310s Stainless Steel Pipe for sale are different. The sawn material has no flattening degree, the hole is accurately bitten, the thickness uniformity of the top of the head is good, and the cutting flattening degree is large. Sometimes the lower difference of wall thickness is large, which usually leads to poor biting. The top of the seamless steel pipe blank head is impacted by the cooling circulating water in the hot rolled strip and the cooling circulating water in the page head. The top of the capillary head generally causes serious internal and external surfaces, and after fine rolling, The top of the head is very easy to crack.
The gap between the top of stainless steel plate seamless steel pipe and the inner cavity of capillary tube shall not be too small. If it is too small, the rough pipe is very easy to cause big twist and wavy lines, and because the gap is small, the fluidity of the top sprinkler circulation system is reduced, and the top is destroyed quickly. Generally, it is 40-6 blank, and the top diameter is not less than 5-6mm of the inner diameter of the rough pipe. Sometimes the top is applied with a large point, and the diameter of the rough pipe can be moderately larger.
