摘要
为提高三级锚链钢的各项机械性能,改善钢的质量,将钛微合金化技术应用于CM690三级船用锚链钢的生产试验中。结果表明,在钛含量为0.020%～0.030%时,所生产的CM690三级船用锚链钢各项机械性能指标不仅达到了国家标准要求,而且其抗拉强度远高于国家标准要求。提高了钢的质量,同时开发出钛微合金化CM690三级船用锚链钢新钢种。
In order to increase the mechanical properties of grade three anchor chain steel for ship and to improve the quality of steel, the technology of Ti micro-alloying was applied in producing grade three anchor chain steel. The industrial practice shown that all mechanical properties of produced anchor chain steel, especially the tensile strength, meet the requirement of national standards when the content of Ti is between 0.020% - 0.030%. So producing high quality new type Ti micro-alloying tertiary anchor chain steel was got.
