Product details
describe
Magnesia bricks need to be used in the walls of the heat storage chamber because they have the ability to resist the erosion of solid powder components (substances carried out by the melting part of the kiln) and alkaline gas media (combustion products of fuel and burning losses of kiln ingredients) in the kiln materials.
Magnesia bricks used in glass kilns have high refractoriness, good alkali slag resistance, and a high starting temperature for load softening. Mainly used for glass kiln heat storage rooms, etc.
