离心铝热法制造陶瓷衬里复合管 Ⅰ.陶瓷衬里不锈钢短管的研制

Ceramiclined compound pipes made by using centrifugal thermit process.Ⅰ.The development of ceramiclined short stainless steel pipes.

研究了离心铝热法制造陶瓷衬里不锈钢短管的工艺。认为合适的条件是：离心分离因素为２００，铝热剂与不锈钢短管的重量比为０．５５～０．６，添加剂为锆英砂。陶瓷衬里管能够承受８００℃的热冲击。讨论了预热温度和气相压力对陶瓷衬里层表面质量的影响。

A study was conducted for the process of making short ceramiclined stainless steel pipes by using centrifugal thermit process.The optimum process parameters were that the centrifugal separating factor was 200,the weight ratio of thermit to short stainless steel pipes was 0.55～0.60,the additive was ZrSiO4 powder.The ceramiclined short stainless steel pipes could resist 800℃ thermalshock,the influence of preheat temperature and gas phase pressure of the surface quality of the ceramiclined layers were discussed.
