铸造生产所用的油芯砂子,过去都只能使用一次就报废了。这不仅浪费了大量的砂子,而且废砂的处理也很困难。我厂铸造车间广大职工,紧密结合生产实践,开展试验研究工作,经过“实践、认识、再实践、再认识”的过程,创造了废油砂流态化再生炉,并已正式用于生产。 Foundry used to create the oil sand, in the past can only be used once scrapped. This not only wastes a lot of sand, but also the processing of waste sand is also very difficult. The majority of workers in our foundry’s workshop, in close connection with the production practice and experiment and research work, have created the waste oil sand fluidized regeneration furnace through the process of “practice, understanding, re-practice and re-understanding” and have been formally used in the production.
