Abstract: The TRIZ theory was applied to analyze the causal chain of zirconia ceramic products contaminated by the atmosphere in the furnace,and the key problems were determined,and the optimal innovation scheme was generated under the guidance of TRIZ tools:when the furnace temperature is below 1 155 ℃,an oxygen enrichment pump is used to introduce oxygen-rich air into the furnace chamber;when the furnace temperature is above 1 155 ℃,the oxygen enrichment pump is turned off to reduce the oxygen content in the furnace chamber;a composite material is used to fabricate a sealed sagger,and the zirconia ceramic products are placed into the sagger in order to separate the MoO₃ contaminated atmosphere in the furnace chamber from the zirconia ceramic products.

Key words: TRIZ theory, high-temperature furnace chamber, contamination, zirconia ceramics

摘要： 运用TRIZ理论对氧化锆陶瓷制品被炉膛内气氛污染这一问题进行因果链分析,确定了关键问题点,并运用TRIZ工具进行指导,确定了最优创新方案:当炉膛温度在1 155 ℃以下时用增氧泵向炉膛内通入富含氧气的空气;当炉温在1 155 ℃以上时,关闭增氧泵,减少炉膛内氧气的含量。同时采用复合材料制成密闭匣钵,将氧化锆陶瓷制品放于其中,用以分离炉膛内MoO₃污染气氛和氧化锆陶瓷制品。
