摘要:
A refractory metal recovery method includes applying a coolant to a wheel grinding operation at a total rate exceeding a total rate at which the coolant evaporates and distributing the coolant across an interface with the abrasive wheel sufficient to apply the coolant at local rates exceeding local rates at which the coolant evaporates. The method produces refractory metal swarf and decreases oxidation of the swarf compared to dry grinding, allowing collection of the swarf. The abrasive grit may have a size of from about 16 to about 24 mesh and the coolant may contain a nitrite.
摘要(中):
难熔金属回收方法包括将冷却剂以总速率超过冷却剂蒸发的总速率施加到车轮研磨操作,并且将冷却剂分布在与砂轮的界面上,足以以当地速率超过当地速率施加冷却剂 冷却剂蒸发。 与干磨相比,该方法产生难熔金属切屑并减少切屑的氧化,从而允许收集切屑。 磨粒可以具有约16至约24目的尺寸,并且冷却剂可含有亚硝酸盐。
