Luoyang Super League forging forging tells you the types and features: When the temperature exceeds 300-400 ℃ (steel blue brittle region) customized ring gear, to reach 700-800 ℃ when precision ring gear, the deformation resistance will be drastically reduced, deformation energy It has also been greatly improved. According to the forging of the ring gear in areas of different temperatures, different quality forgings and forging process requirements for, it can be divided into cold, warm forging, hot forging three molding temperature region. This temperature zone is divided originally no strict boundaries, generally speaking, in forging the recrystallization temperature region have called forging, forging without heating at room temperature is called cold forging. Luoyang Super League Forging Co., Ltd. for your organization about forging defect Follows is an example: It should be noted that the various methods of forming common defects and major defects in various materials forgings all have their laws. Different forming methods, because of their different stress situations, stress-strain characteristics are not the same, the main flaw which may produce is not the same. For example, the major drawback is that the blank side upsetting surface vertical or 45 ° direction of cracks on ingot upsetting, the lower end of the regular cast of residual tissue; major defects rectangular section blank when stretching is transverse crack surface and corner crack, crack inside the diagonal and horizontal cracks; open die forging major drawback when it is fully satisfied, folding and wrong move and so on. The major step in forming common defects will be described in detail in Chapter IV. _ Super League forging ring forging quality assurance (certification) _ by the Luoyang Super League Shanxi ring forging Limited.
