一、引言烧氢炉是陶瓷金属化的重要设备之一,其性能好坏直接影响到金属化零件的质量,以及生产和试制的周期。我们金属化用烧氢炉是一台由苏修烧氢炉改装而成的卧式炉,自65年投产以来,升温速率一直是个老大难问题,由室温升至1500℃需要8～9小时,这样的升温速率远远不能适应我厂多品种、小批量,以及兼有试制性质的 I. INTRODUCTION The hydrogen-burning furnace is one of the important equipment for ceramic metallization. Its performance directly affects the quality of the metal parts, and the cycle of production and trial production. Our metal-burning hydrogen-burning furnace is a horizontal furnace converted from the Soviet-built hydrogen-burning furnace. Since its commissioning in 65 years, the heating rate has been a long-standing problem. It takes 8 to 9 hours from room temperature to 1500 ° C , So the heating rate is far can not adapt to our plant variety, small quantities, as well as trial-and-
