Abstract

Information impactogram application for fast detection of temperature instability zone of a two-channel ceramic roller kiln

Highlights

  • Industrial production of ceramic tiles is highly encumbered by energy expenditures, high competition, and inadequate working force

  • Conclusion: the possible failure impact is exhibited in almost whole maximum temperature zone of both channels of the roller kiln, signals from the kiln are not indicated as the fallout cause because their entropy values are too far from the entropy of the quality control (QC) signal

  • Based on the current results, a workflow was proposed for quality control applicable to ceramic tile production based on information impactogram

Summary

Introduction

Industrial production of ceramic tiles is highly encumbered by energy expenditures, high competition, and inadequate working force. The correspondent data for one-dimensional tessellation entropy are given in Tab. An excerpt of measurement signal shift reports from two-channel roller kiln for raw tiles from press in the period August and September 2009 is given in Tab. 3. Press 5 (Fig. 2a): shift instance 3 was unfavourable with fallout of 6,17 % but not a single kiln signal is in the influence zone. Conclusion: kiln signal after tile from press 8 does is not indicated as the cause of critical fallout in shift instance 2. 2) Shift instance 22 (Fig. 1) was unfavourable with fallout rate of 6,03 %, but there was no code indication of the roller kiln signals.
