Some of the waste refractory bricks that need to be removed from the furnace for repairs look very good in appearance and have no obvious damage. So can the waste refractory bricks be rebuilt into the kiln? Many people have different opinions. I think it is inappropriate. of. The main reasons are as follows:
- kiln, careful masonry, masonry quality of the kiln life, fuel consumption, glass melting and wire drawing operations have a great impact, if the waste refractory brick masonry to meet the kiln on the brick masonry dimensions and the kiln thermal expansion and other basic requirements;; 2 because of the waste refractory bricks have been fired at high temperatures, the more or less will have some expansion, then the expansion gap between the refractory bricks is very difficult to control; the expansion gap between the fire is very difficult to control.
- As the used refractory bricks have been burned at high temperature, they will have some expansion, so it is difficult to control the expansion joints between the refractory bricks in the masonry.
- Because of the waste refractory bricks in the original masonry are after high-pressure force, its strength has been reduced a lot, if used again, affect the overall performance of the kiln.
