机械、电器、交通、船舶、锅炉和排灌等一切产品的制造,在切割和焊接过程中,都要耗用大量的电石。特别是在生产大跃进以来,电石的需用量尤其迅速增长。然而目前由于生产电石设备和电力的不足,所以电石的供应还是非常紧张,有时只能满足生产需要量的50～60％左右。因此,好些工厂企业,由于电石缺乏,不得不使用锯、冲、锤、 The production of machinery, electrical appliances, transportation, ships, boilers, irrigation and drainage, and other products require a large amount of calcium carbide in the cutting and welding process. Especially since the Great Leap Forward, the demand for calcium carbide has grown particularly rapidly. However, the current shortage of calcium carbide equipment and electricity, so the supply of calcium carbide is still very tight, and sometimes only meet the production needs of about 50 to 60%. Therefore, a number of factory enterprises have to use saws, rams, hammers due to the lack of calcium carbide.
