自从六十年代苏联开始研究电液压清砂以来,现已广泛清理各种铸件,不论是有色还是黑色金属铸件;不论是砂型还是熔模铸件;不论铸件大小还是复杂程度,均可用此法来清砂。由于这种清砂方法具有耗电少、效率高、成本低、无粉尘、劳动条件好等优点,在苏联已有200多家工厂采用了30多种型号的电液压清砂设备,其效果十分显著。仅1974年一年就节省600万卢布,有四千名清砂工人从恶劣的工作中解脱出来。
Since the Soviet Union began to study electro-hydraulic sand cleaning in the 1960s, various castings have been extensively cleaned up, whether colored or ferrous metal castings; whether sand or investment casting; regardless of the size or complexity of the castings can be used to clear sand. Because of this sand-cleaning method with less power consumption, high efficiency, low cost, no dust, good working conditions and other advantages, in the Soviet Union has more than 200 factories using more than 30 types of electro-hydraulic sand cleaning equipment, the effect is very Significant. In the year 1974 alone, 6 million rubles were saved and 4,000 sand-cleaning workers were freed from poor work.
