Abstract

본 발명은 열간단조후 균일 냉각 방법을 이용하여 제품간의 품질편차를 제거할 수 있으며, 제품의 방출열의 재활용에 의하여 에너지의 효율을 증대시킬 수 있고, 변태완료후의 냉각 공정을 수냉방식으로 함으로써, 생산성을 향상시킬 수 있는 비조질강의 열간단조후 냉각방법을 제공하는 것을 목적으로 한다. 열간단조된 비조질강부품을 약 825~875℃로 공냉시키는 단계, 공냉한 비조질강을 약 425~450℃로 제어냉각시키는 단계, 및 제어냉각된 비조 질강을 수냉시키는 단계를 포함하는 것을 특징으로 한다. 또한, 제어냉각단계에서 방출된 열을 이용하여 수냉단계이후에 건조단계가 추가로 포함하며, 공냉단계에서 강제 공냉이 행해지는 것이 바람직하다.The present invention can remove the quality deviation between the products by using a uniform cooling method after hot forging, can increase the efficiency of energy by recycling the heat of the product discharge, and by the cooling process after completion of transformation into water-cooling method, productivity It is an object of the present invention to provide a cooling method after hot forging of non-alloyed steel which can improve the temperature. Air cooling the hot forged non-steel parts to about 825-875 ° C., controlling and cooling the air-cooled non-steels to about 425-450 ° C., and water-cooling the controlled cooled non-steels. . In addition, a drying step is further included after the water cooling step by using the heat released in the controlled cooling step, and forced air cooling is preferably performed in the air cooling step.
