摘要： A refractory brick made from a size graded batch comprising 20-30 weight percent magnesite containing less than 0.8 weight percent silica, and the balance a chrome ore. The chrome ore includes oxides of chromium, aluminum and iron wherein the ratio between the oxides of chromium and the oxides of aluminum and iron is greater than 2 to 1. The silica content of the chrome ore is less than 2.7 weight percent, the iron oxide content is less than 17 weight percent, and the chrome ore to magnesite ratio is between 2.33 to 4 to 1.

摘要： Direct bonded refractory bricks are provided containing 40 to 70 percent by weight magnesia, 60 to 30 percent by weight chrome ore, and having an overall lime to silica ratio less than 0.30 and a silica content of less than 2.5 percent by weight based on the weight of the brick. The silicate phase of the bricks is essentially non-wetting and non-reactive with secondary spinels at 2,700*F. The lime to silica ratio and silica content are controlled by adding a hydrated silicate compound, such as a magnesium silicate, to the magnesia-chrome ore mixture before it is fired.

CHROMITE GRAIN FORMS 10-35% OF BATCH AS -10+150 MESH PARTICLES. OTHER TWO GRAINS FORM THREE PARTICLE FRACTIONS: 3060% OF BATCH BEING COARSE -4+20 MESH, 0-30% OF BATCH BEING INTERMEDIATE -10+35 MESH, AND FINE MAGNESITE GRAIN IS AT LEAST 10% OF BATCH. THE TOTAL +28 MESH PARTICLES OF CHROMITE GRAIN AND MAGNESITE GRAIN CONSTITUTE 4 TO LESS THAN 50% OF BATCH. BODY BURNED AT ABOUT 1600* C. CHARACTERIZED BY MODULUS OF RUPTURE AT 1340*C.
