Abstract:

This paper analyzes the reasons for black core in silica brick in the firing process of tunnel kiln and proposes corresponding solutions on that basis.Tests revealed that the K value and M value tend to be reasonable by improving the loading methods and kiln car,and the temperature differences are narrowed and the black cores are eliminated to reduce energy consumption and save production cost for positive effects.
