Corundum burner nozzle was characterized by its chemical stability, and strong resistance to acid/alkali slags, metals, and liquid glass, etc. The thermal shock stability is decided by its structure. Usually, the dense refractory products have superior anti-erosion ability, but bad thermal shock stability.
To control the corundum product quality, we need to analyze the key factors causing the product damages. Firstly, to decrease the content of Si02 in the corundum products. Secondly, superior technical measures to ensure the low creepy ratio. Either corundum or mullite, their anti-alkali ability is not good. The materials are easily damaged once content of SiO2, even a little amount, as which formatsβ-Al2O3 that causing the volume expansion 6%~20%.
The regenerative burners are mainly used in the field of industrial gas heating equipment.
For copper smelting furnace burner, usually, SIJIHUO recommends corundum mullite material for customers reference. Due to the crystal structure is more stable, and more conducive to release the mullite and corundum excellent properties. By combing both materials together to achieve high temperature at 1840 ℃, it is helpful for the improvement of the material high-temperature performance.
