rate stabilization

The relationships between oxidization/ car-bonization/ graphitization temperature, heating rate, raw material type of mesophase pitch and oxidative stabilization extent, graphitization extent, tensile strength/ modulus, electric resistance, and fiber structure are discussed.

讨论了氧化碳化与石墨化温度、升温速率、中介相沥青原料种类与氧化稳定化程度、石墨化程度、抗张强度与模量、电阻率、纤维结构的关系；

The practical production test shows good system stabilization and mathematical model accuracy. The temperature tracking maximal deviation is 1.47%, and furnace temperature optimum setting value can meet heat treating technology needs, and the qualification rate of the billet is more than 98%.

经现场实际生产检验，系统运行稳定，模型准确可靠，温度跟踪最大误差1.47%，炉温优化设定值满足热处理工艺要求，热处理钢坯合格率达到98%以上。
