The induction heating method can be used for on-line, high-efficiency and high-power density heating of stainless steel pipes to achieve the purpose of solid solution heat treatment.
Since most austenitic stainless steels (304, 316, etc.) are not magnetically permeable, ordinary power sources for heating magnetically permeable steel pipes cannot be used. Instead, the diameter and wall thickness of steel pipes need to be considered in accordance with the electromagnetic characteristics of non-magnetic stainless steel , Special matching for power supply; power supplies with different tube diameters and different wall thicknesses are very different, with tube diameters ranging from 2mm to 762mm and wall thicknesses ranging from 0.2mm to 50mm. 20KW-1600KW, the frequency range covers 3KHz-300KHz.
The stainless steel tube on-line solid-smelting induction heating power supply generally runs at high power output and requires continuous and uninterrupted operation. Most of the equipment adopts PLC remote control and automatic temperature control. This has an effect on the overall efficiency, reliability and temperature of the equipment. Control functions, equipment life, and maintenance costs all demand high requirements.
Globally, Kechuang has hundreds of sets of stainless steel tube on-line solid-smelting equipment in operation. These products generally run at least 8 hours a day, and many of them operate continuously for 24 hours without interruption. The products have high reliability.
