| 摘 要： | 研究了填充密度、预热温度及添加剂等条件对铝热－重力分离法制备陶瓷复合钢管的影响，随填充密度增大反应速度减慢。预热可以提高反应速度。适当的添加剂可以调节反应速度，使反应过程易于控制。应用的铝热－重力分离法成功地制出了高炉煤粉喷枪枪头，延长了其使用寿命，并一次合成了直径５０ｍｍ￣２７３ｍｍ的弯头。

| Abstract: | The effects of filling density preheating temperature and additives on the ceramic lined steel pipe made by thermite-gravitational separaion process were studied. It shows that the propagating rate of the combustion wave along the steel pipe decreases with increasing the filling density and increases with increasing the preheating temperature. Furthermore, it becomes contrellable with the addition of suitable additives.The coal powder nozzle produced by thermite-gravitational separation process has been used in blast furnace.The bend pipes with the diameter of 50~273 mm were also produced by this process. |
