Automatic Electric Steel Machinery, Brand Name : HANGAO

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.
