- 摘要:
- 针对4D缸体在生产中出现气孔、烧结、砂孔等问题,采取工艺补正、选择特种覆膜砂及涂料等多项工艺措施,最终使其质量问题得到有效的控制。并对其质量问题的解决过程进行总结概述,进一步提升对干式缸体的缺陷的分析能力及管控对策。Aiming at the defect problems of porosity, sintering and sand hole in the production of 4D cylinder block, a number of technological measures, such as process correction, selection of special coated sand and coating, were adopted to effectively control the quality problems. It also summarizes the process of solving quality problems and further improves the analysis ability and control countermeasures of the defects of the dry cylinder block.
