The conclusions are as follows: 1) According to the law of Ostwald repening, the coarsening rate of titanium carbonitride inclusion is very small, the coarsening behavior of titanium carbonitride inclusion cannot be considered in the heating and holding stage. 2) The solid solution behavior of titanium inclusion in the heating process is obviously existed. 3) Through the proper control of rolling temperature, holding time and the subsequent cooling rate, the size and quantity of large particle titanium inclusion in the high strength tire cord steel can be effectively controlled.展开更多
利用固相力化学反应器实现对废旧轮胎橡胶的常温力化学脱硫化。实验结果,表明胶粉的交联密度和凝胶含量随碾磨次数增加显著降低,通过碾磨,再硫化橡胶的力学性能得到显著提高。碾磨40次后,拉伸强度由碾磨前2.3 M Pa提高到10.9 M Pa;断裂...利用固相力化学反应器实现对废旧轮胎橡胶的常温力化学脱硫化。实验结果,表明胶粉的交联密度和凝胶含量随碾磨次数增加显著降低,通过碾磨,再硫化橡胶的力学性能得到显著提高。碾磨40次后,拉伸强度由碾磨前2.3 M Pa提高到10.9 M Pa;断裂伸长率由碾磨前的69.6%提高到290.0%。再硫化胶的断面形貌分析表明,用脱硫胶制得的胶片具有良好的界面结合。展开更多
