Decarburization speed guarantee and demagnetization mode of 316L stainless steel plate

According to the traditional process of 316L stainless steel plate, the oxygen is blown by oxygen to remove carbon. Therefore, the labor intensity of the worker is relatively large, and the consumption of the oxygen pipe is relatively large. In fact, it means that the decarburization speed is relatively slow, resulting in smelting time. Extended, repeated power transmission, high power consumption.
In this regard, even if oxygen decarburization provides chemical energy to the molten pool, because the smelting time is prolonged, the solvent continues to lose heat, and the oxidation heat release value is lower than the heat dissipation value of the molten pool, so the power consumption is increased.
It is precisely because of this that the decarburization speed of the 316L stainless steel plate is directly applied to the water-cooled oxygen lance of the furnace door. When the oxygen pressure is greater than 6, the decarburization speed will be at 04-06, thus It not only guarantees the decarburization speed, but also provides a large amount of chemical energy to the molten pool without reducing the smelting time, which reduces the smelting power consumption.
In order to completely eliminate the magnetic properties of the 316L stainless steel plate, first of all, the stable austenite structure can be recovered by high-temperature solution treatment, which can also eliminate the magnetic properties.
It is precisely because of this that the magnetic properties of the 316L stainless steel sheet material are determined by the regularity of the molecular arrangement and the homology of the electron spin to determine the physical properties of the material.
It should be pointed out that if the stainless steel plate is subjected to different degrees of magnetic properties after cold working, or expressed in physics terms, the stainless steel plate generates a structure in which magnetic origin is derived from electron spin, and electron spin belongs to quantum mechanical machine. performance.
In addition, the 304 stainless steel plate is cold-processed, and the microstructure is also transformed into martensite. The greater the cold-working deformation, the more the martensite transformation, and the stronger the magnetism.
Due to the above reasons, the magnetic properties of the 316L stainless steel plate are not at the same level as the magnetic properties of the stainless steel plates of other materials. In other words, the magnetic properties of the 316L stainless steel plate are always weakly magnetic.
At this time, we need to accurately identify and distinguish, and then, it can be handled in a targeted manner.
