由长春第一汽车制造厂与哈尔滨科学技术大学联合完成的蠕墨铸铁汽车制动鼓试验研究成果鉴定会于1986年1月21日至23日在长春召开。与会代表审查了课题组提交的有关技术文件,并进行了现场参观和测试,经讨论一致认为,可以通过技术鉴定。该项目主要研究采用蠕虫状石墨铸铁代替片状石墨铸铁生产汽车制动鼓,以提高其耐磨性,改善汽车制动的安全可靠性和平稳性,并减轻汽车自重。通过试生产和装车试验结果表明,蠕墨铸铁制动鼓的耐磨性平均为灰铸铁制动鼓的2倍,且具有良好安全可
By Changchun No. 1 Automobile Factory and Harbin University of Science and Technology jointly completed vermicular graphite cast iron drum brake drum test research appraisal will be January 21, 1986 to 23 held in Changchun. Participants reviewed the technical papers submitted by the research group and conducted site visits and tests. After discussion, they agreed that they can pass the technical appraisal. The project mainly studies the use of worm-shaped graphite cast iron instead of flake graphite cast iron to produce automobile brake drums to improve its wear resistance, improve the safety, reliability and stability of automobile brakes and reduce the weight of automobiles. Through trial production and loading test results show that the compacted graphite cast iron brake drum wear resistance average of two times the gray cast iron brake drum, and has good safety
