铸造作业在机器制造工业中占有重要的地位。一般机器产品的零件毛坯,大约有65%—80%是从铸工厂里铸造出来的。铸造作业所涉及的范围很广泛。它的性质也很复杂。在整个工艺过程中,它要求着高度的集体性与组织性,从选砂、造型、配料、熔化、浇铸一直到打箱清砂,如果稍一不慎或组织不当,都会使得铸品报废,使得生产能力不能很好地发挥。 Casting operations play an important role in the machine manufacturing industry. About 65% to 80% of the parts blanks of general machine products are cast from casting factories. Casting operations involve a wide range of fields. Its nature is also very complicated. In the entire process, it requires a high degree of collective and organizational nature, from sand selection, modeling, batching, melting, casting, and box sanding. If one is careless or improperly organized, the cast will be scrapped. Make production capacity not play well.
