摘　　要：大型船用柴油机气缸套采用离心铸造工艺生产,在生产过程中会产生夹渣、缩松与缩孔、花纹、白口等铸造缺陷。研究表明,通过提高冷却速度、高温出炉、低温浇注以及严格控制化学成分等工艺措施可有效地防止此类铸造缺陷,从而显著提高缸套的产品质量。The diesel engine cylinder sleeve used for large.marine was produced by centrifugal casting process, there were inclusion, shrinkage porosity, shrinkage cavity, pattern, cementite and other casting defects in the production process. The research results show that taking the measures of increasing cooling rate, increasing melting temperature, pouring at low temperature and strict controlling chemical composition can effectively prevent such casting defects, so as to significantly improve the product quality of cylinder sleeve.
