摘　　要：对石墨化增碳剂和高硫高氮增碳剂对柴油机缸盖力学性能的影响进行了研究。大量的生产试验表明,在发动机缸盖生产中使用高硫高氮增碳剂比使用石墨化增碳剂单铸试捧的抗拉强度提高约50 MPa,硬度提高HBS10,同时提高了缸盖材料的性能和加工性能,降低了生产成本。The effect of graphitization and high sulfur nitrogen recarburizer on mechnical properties of engine cylinder head was studied. The production test show that tensile strength of separately cast bar was increased 50 MPa, hardness was increased HBS10, the processing performance of cylinder head was improved, the production cost was decreased.
