一、概述在伟大领袖毛主席的“五七”指示指引下,我们双方协作,对用超声波清除精密铸造中蜡模组的蓖麻油进行了试验。以前清除精密铸造蜡模上的蓖麻油,是由人在肥皂溶液中刷洗,用软纱布擦。由于工件形状特殊,必须先单工件清洗,然后组合再整体清洗。这样不仅工效低,质量不能保证,而且经常打破蜡模组。每班3～4人才能清洗五、六十组。 I. OVERVIEW Under the guidance of Chairman Mao’s “May-July” directive, both of us collaborated to test the castor oil used for wax removal in precision casting by ultrasonic wave. Castor oil was removed from precision cast wax molds before, and was scrubbed by people in a soap solution and rubbed with a soft gauze. Due to the special shape of the workpiece, you must first single-piece cleaning, and then combined with the overall cleaning. This is not only inefficient, quality can not be guaranteed, and often break the wax module. 3 to 4 people in each class can clean five or sixty groups.
