1, through the induction of alternating magnetic field generates eddy currents within the workpiece 301 stainless steel wire, the current distribution in the cross section of the workpiece is no longer uniform current is mainly concentrated in the surface matte stainless steel wire, called the skin effect. Due to the skin effect, from the surface to the core wire induced current gradually decreases liaobu stainless steel wire, steel wire core insufficient heating, the temperature rises slowly than the surface of stainless steel wire, must fully consider the frequency induction heating, the heating time was reasonable measures temperature and average temperature time to achieve consistent core surface temperature. 2, the structure of a small induction furnace air rate cut means that good electromagnetic coupling, but the wire is moved in the guiding device, it must have sufficient clearance so that the wire will not generate grazing the inner wall of the short circuit coil brass. Wires and sensors to maintain good concentricity. Length higher efficiency and compact sensor. Especially for heating non-magnetic steel wire, the length of the sensor should be at least five times the inner diameter. 3, frequency selective induction heating wires are penetrating heat, select the frequency of the main consideration two factors: the temperature uniformity of heating induction heating efficiency and wire section. Penetration reasonable relationship between the two parameters depth δ circuits and wire diameter D, wire induction heating for 6> δ / D> 3. Two phases. Stainless steel wire rope American International Iron and Steel Institute labeling method is to use three numbers to indicate a variety of standard grade stainless steel malleable. Where: ① austenitic stainless steel 200 and 300 series of numerals, for example, some of the more common austenitic stainless steel is 201, 304, 316 and 310 marks. ② ferritic and martensitic stainless steel 400 series is represented by a number. ③ ferritic stainless steel is marked 430 and 446, 410, 420, and 440C martensitic stainless steel is marked, duplex (austenitic - ferritic). ④ stainless steel, precipitation hardening stainless steel and high alloy iron content of less than 50% usually uses proprietary name or trademark name. Stainless steel wire rope a standard classification and grading, grading and classification: ① national standard GB ② industry standard YB ③ ④ local standards enterprise standard Q / CB stainless steel coil, stainless steel wire, stainless steel supplied by Dongguan Shengyuan Shengyuan Stainless.
