有些铸铁件铸造中的缺陷(砂眼、气孔、夹砂等)短时期内不易被发现,经过机器的不断运转振动,缺陷暴露了,故障突然出现:漏油、漏水、漏气,使机器不能正常工作。如一时无法送厂修理,砂眼、气孔又不大时(一般5毫米以下),可采取下述临时措施:取一些生铁屑,越细越好,若一时没有,可用锉刀从废旧铁件上取下,然后用较浓的盐水拌匀铁末后注入砂眼,并捣实,数小 Some cast iron casting defects (trachoma, porosity, sand, etc.) is not easy to be found within a short period of time, after the continuous operation of the machine vibration, defects exposed, sudden failure: oil spills, leaking, so that the machine can not be normal jobs. Such as temporary delivery can not be repaired, trachoma, stomata and not large (usually 5 mm below), can take the following temporary measures: Take some of the raw iron filings, the more detailed the better, if not for a moment, available file from scrap iron Next, and then use a thick brine mixed with iron into the trachoma, and tamping, a few small
