Temperature is the main factor affecting the quality of American Standard stainless steel coil. First, the uniformity of the heating temperature of the billet directly affects the uniformity of the wall thickness of the perforated capillary tube and the quality of the inner surface, which in turn affects the quality of the wall thickness of the product. Secondly, the temperature and uniformity of stainless steel coil in the rolling process (especially the final rolling temperature) is related to the mechanical properties, dimensional accuracy and surface quality of the product delivered in the hot-rolled state, especially when the billet or billet is overheated or even overheated, which can also cause waste. Therefore, in the production process of hot-rolled seamless pipes

The quality of process adjustment and work mainly affects the geometry and appearance quality of stainless steel coil.

The quality of the tool, stable or not, is directly related to the dimensional accuracy of the product, surface quality and tool consumption can be effectively controlled; the quality of the mandrel surface treatment (chrome plating) is affected. The inner surface of the stainless steel coil, the second is to affect mandrel consumption and production costs.
