TTT分析在陶瓷烧成质量控制中的研究和应用

Research and Application of TTT Analysis on Quality Control of Ceramic Firing

本文介绍了TTT(time-temperature-transformation)分析的工作原理和应用方法,主要介绍了它在陶瓷烧成工艺控制中的作用。以红砖烧成中TTT分析的结果为例用图表的形式加以说明。实践证明,这是一种有效的质量跟踪和控制手段,对指导工厂生产、稳定和提高烧成质量起到积极的作用。它和差热(DTA)、热重(TG)、热膨胀分析相比,更适合在工厂中应用,作为一种动态、在线的质量控制手段有着广泛的应用前景。

The article introduces the workingtheory and applying of TTT(time,temperatureand transformation)analysis,primarily introduces how it works in controlling the firing of the ceramic body.The essay illustrates its action with the results of the TTTanalysis on the firing of the red brick body.The experimentsprove that it is a good way of tracking and controlling the quality of the ceramicbody and it can play an active role in the producingand optimiz-ing firing.Comparedwith the different thermal analysis and the derivative Thermogrivimetry,it is very popular with the brick makers.As an active controlling way on line,it will be applied widely.
