The Reducing Of Quality Characteristic Value Fluctuation Of Pusher Kiln Furniture (Slab) By Taguchi Method

The ferrite magnetic core is cranked out in"pusher kiln"under high temperature, setting kiln ambience and heat preservation time. The most important kiln using in"pusher kiln"is"slab".In kiln ,"slab"will continuously endured high temperature, weight(vertical and horizontal), execrable firing ambience and sudden cold & heat impact. Even if any single piece out of its way, split will happen, thereby engendering kiln accident. Kiln accident usually gives birth to a big loss. So quality stability of"slab"is highly required.This paper brings forward that using Taguchi Method to optimize controls parameter. Thereby, productions can have"robustness"to face interferential factors in production process and reduce the eigenvalue fluctuating.This paper firstly sum up the Taguchi Method's background, development and application overseas, development in our country and in industry.Secondly, particularize its conception, content and some details in application. Then aim at our own factory's production process and analysis the interferential factors at length, recognize the interferential factors and controlling factors, confirm the best level of controlling factors by using Taguchi Method parameter setting program. And validate aforesaid level and validity of the hypothesis by validated experiment. Then finish the optimization of controls parameter.Finally, the paper made a Summary, and prospect the direction and domain of future research.
