        詳細介紹:

        回火是將淬火鋼加熱到Ac1以下的某一溫度,保溫必然光陰,而后冷卻到室溫的熱處分工藝。它的要緊目的為:


        (1)合理地調解鋼的硬度和強度,進步鋼的韌性,使工件滿足應用要求;


        (2)穩定構造,使工件在永遠應用歷程當中不發生構造轉變,從而穩定工件的樣式與尺寸;


        (3)?低落或消除工件的淬火內應力,以削減工件的變形,并防止開裂。

        Tempering is a process in which the quenched steel is heated to a temperature below Ac1, the heat is inevitable, and then cooled to room temperature. Its main purpose is:


        (1) Reasonably adjust the hardness and strength of the steel, improve the toughness of the steel, and make the workpiece meet the application requirements;


        (2) Stable structure, so that the workpiece does not undergo structural transformation during the permanent application process, thereby stabilizing the style and size of the workpiece;


        (3) The low internal pressure of the workpiece is reduced or eliminated to reduce the deformation of the workpiece and prevent cracking.
