The alkaline refractory heat storage products made with partial prefabricated reaction magnesium iron sand .The main minerals consist of calamite, spinel and a small amount of silicate. The granule is the milky structure and the spinel is fully developed. The matrix part is the somatic turbidity structure. The crystal is a kind of magnesium iron sand directly combined with the structure of low porosity products. The product is homogeneous in composition, stable in performance, with high thermal conductivity, super hot melt ratio, load softening temperature and high temperature mechanical strength, and strong chemical erosion resistance of alkaline slag.
