在热处理过程中,由于工件绑扎不牢,经常掉入冷却剂(硝盐、碱浴、水、油等)内,用长把钳子打捞,很不方便。多年来,我们一直使用马蹄形磁铁打捞工件,既方便又省力。当冷却槽很大时,用铁丝绑住磁铁,放入冷却槽掉工件的方位,也会很快就打捞上来。当掉入500℃以下的热浴中,也可应用,但将磁铁放入500℃以下热浴中后,要等粘在磁铁上的介质(如硝盐)熔化后再打捞,只几分钟就可捞上工件。但要注意,磁铁从热浴中取出
In the heat treatment process, because the workpiece is not strong banding, often fall into the coolant (salt, alkali bath, water, oil, etc.), with long pliers salvage, very inconvenient. For many years, we have been using horseshoe magnets to salvage workpieces, which is convenient and labor-saving. When the cooling tank is large, the iron wire tied to the magnet, into the cooling tank off the workpiece orientation, will soon be salvaged. When dropped into the hot bath below 500 ℃, can also be applied, but after the magnet into the hot bath below 500 ℃, the medium must be attached to the magnet (such as salt) melted before salvage, only a few minutes Can be fishing on the workpiece. Note, however, that the magnet is removed from the hot bath
