正常化處理維加熱至A3點或Acm點以上40~60℃保持一段時間，使容器板組織變成均勻的沃斯田體結構后，在靜止的空氣中冷卻至室溫的熱處理程序。
The normal processing of Vigage to A3 or Acm at 40~60 DEG C for a period of time, the container plate into a homogeneous austenite structure after heat treatment process in the still air cooling to room temperature.
對亞共析鋼而言，可獲得晶粒細化的目的而擁有好的強度與韌性；對容器板而言，則可防止雪明碳鐵在沃斯田鐵晶粒邊界上形成網(wǎng)狀析出，以降低材料的韌性。
Of hypoeutectoid steel, can achieve the purpose of grain refinement has good strength and toughness; the container plate, can prevent cementite precipitated in austenite formed at the grain boundaries, to reduce the toughness of the material.
完全退火處理主要目的是要軟化容器板、改善容器板之切削性，其熱處理程序為加熱至A3點以上20~30℃（亞共析鋼）或A1點以上30~50℃持溫一段時間，使形成完全沃斯田體組織后（或沃斯田體加雪明碳體組織），在A1點下方50℃使充分發(fā)生波來體變態(tài)，獲至軟化的鋼板。
The main purpose is to complete annealing softening container plate, improve the cutting of container plate, the heat treatment procedure is heated to above A3 20~30 C (hypoeutectoid steel) or above A1 to 30~50 DEG C temperature for a period of time, so as to form a fully austenitic Organization (tissue or austenite and snow tomorrow carbon, full body) occurred in A1 pearlite weirdoes below 50 DEG C, to soften the steel plate.
另外應力消除退火則是在變態(tài)點以下450~650℃加熱一段時間后徐徐冷卻至室溫，可消除容器板內(nèi)部在切削、沖壓、鑄造、熔接過程所產(chǎn)生的殘留應力。
In addition, stress relief annealing is slowly cooled to room temperature after heating for a period of 450~650 below the abnormal point, which can eliminate the residual stress caused by cutting, stamping, casting and welding process.
