在连续式淬火装置中淬火,通常是借助于电炉的输送设备将热工件送入盛有冷却液的槽中。工件浸入冷却介质是淬火的一个重要步骤。这一步骤将决定工件与淬火槽传送带的承接表面接触时的工件温度与能量;因而也决定尔后受撞击时是否会出现凹陷与变形。不知道零件的浸沉速度(以及与此相应的浸沉时间)就不可能进行恰当的冷却计算、不可能评价工件受撞时的机械性能,也不可能正确选择适合于各类型工件的淬火油槽深度。
Quenching in a continuous quench unit, hot workpieces are usually fed into the tank containing the coolant by means of the delivery equipment of the electric furnace. Immersion in the cooling medium is an important step in quenching. This step will determine the work piece temperature and energy when the work piece comes into contact with the receiving surface of the hardened flute conveyor; thus, it is also determined whether the depression and deformation will occur later upon impact. It is not possible to evaluate the mechanical properties of a workpiece without knowing the submergence speed of the part (and the corresponding immersion time), nor to correctly select the depth of the quench tank suitable for each type of work piece.
