Sillimanite, Kyanite and Andalusite in China and Their Applications Part II: Their Applications in Refractories to Improve Resistance to Creep and Thermal Shock |
|
| Abstract: | As a second part under the title, this paper introduces the applications of sillimanite group minerals (SGM) in refractory products for hot blast stove, blast furnace, torpedo, hot metal mixer, etc., with emphases on their uses in the low creep and thermal shock resistant bricks for tuyere and iron notch of blast furnace and checker brick and ceramic burner of hot blast stove, taking use of their phase transformation to form primary mullite and secondary mullite, accompanied by volume expansion. The developed SGM containing refractories have found wide uses in major domestic iron and steel making plants to meet the requirements of longer service life, higher service temperature and intensified operations. |
