摘要：PURPOSE:To cool refractory materials with good efficiency and prolong service life by using the refractory materials which have high heat conductivity of specific regions and have specific molten steel erosion resistance and molten slag resistance as internal lining and permanent lining refractory materials. CONSTITUTION:The refractory materials which have heat conductivity of the shaded region in the figure, of which chemical components are 75-76 Mgo and 22 33C in wt%, and which have the characteristics of 300kg/cm<2> in compressive strength, 0.5 in molten steel erosion resistance and 0.1 in slag erosion resistance are used as internal lining and permanent lining refractory materials. The refractory materials having the above-mentioned characteristics are produced by compounding magnesia, magnesia dromite, spinel, and alumina such as magnesia carbon, magnesi a dromite carbon, spinel carbon and alumina carbon and carbon in the form of graphite.
