1957年10月,乌拉尔重机厂试验成功一种清除铸铁件和铸钢件上粘砂的新方法——电解法。达一方法的主要过程就是把需要清除粘砂的铸件放入一个盛有熔盐的电解槽中,然后再向电解槽通直流电。以前,清除大而复杂铸件上的粘砂,需8～10小时,而现在只需30～40分钟,并且劳动条件还大大改善了。 In October 1957, Ural Heavy Machinery Factory successfully tested a new method for removing sticky sand on cast iron and steel castings - the electrolysis method. The main process of a method is to place the castings that need to be cleaned of sticky sand in a molten salt bath and then to the electrolyzer. In the past, the removal of sticky sand on large and complex castings required 8 to 10 hours, now it takes only 30 to 40 minutes, and working conditions have been greatly improved.
