砖体上翘的成因及对策初探

THE REASON OF WARPAGE OF BRICK AND THE WAY TO DEAL WITH IT*

本文详细地介绍了一个因窑炉结构、排烟系统不合理，导致产品严重上翘的实例。通过更换排烟风机，改进排烟管路，增加挡火墙、挡火板，加装两节窑炉延长预热带等改进措施以达到降低过大的烧成正压，改善窑内气流分布状态，强化预热期氧化效果之目的，彻底解决了上翘问题，取得了比较理想的烧成效果。

The paper introduces in greater detail the fact that brick is warping because the kiln structure and fume system are not reasonable.We can solve completely the problem of warpage and achieve a good burning result by changing fume aerator,improving flue pipe,increasing bag wall and board flash,assembying two rooms of furnace again and lengthening preheating zone and so on to cut down too high burning barotropy and improve the state of air scattering and the oxidizing result of preheating period.
