Stainless steel annealing SGL-NB-60

Induction Heating Bright Annealing Machine for DIN Standard Stainless Steel Tube Brief introduction: Process Flow On-Line Fixing & Fusing (Anealing) equipment can heat the stainless steel welded pipeto 1050°C then cool it to the temperature lower than 100 °C under the protection of hydrogen.The heating power supply of the intermediate ferquency induction is the newest DSP+IGBT structure.With DSP digital control system,there are self protection and self diagnostic functions.With small volume,it heats pipes rapidly and efficiently with energy-saving and low-waste features.The especially developed inducer designed according to the features of stainless steel can save 15%-20% energy in contrast of other products of the same class.Using hydrongen as of gas every minute. Function 1. Reduce the hardness of steel pipes, improve the plasticity, to facilitate cutting machining and cold deformation. 2. Fine grains and homogeneous steel organization and composition, to improve the performance of steel, also to make preparation for the heat treatment. 3. Remove the residual internal stress in steel, to prevent deformation and cracking. 1.Power system a.Medium frequency power that inverter by IGBT transistor b.Slot compensation power 2.Movable bright annealing section and cooling tunnel c.Induction heating section d.Heat preservation section e.Cooling water tunnel f.Gas protection device g.Infrared thermometer h.Gas pressure detector i.Circulating-outside water colling system 3.Electrical control system
