Abstract

Procedure for the manufacture of refractory bricks fired from a mixture of sintered magnesia and chromium ore, both starting materials having fine grains less than 0.15 mm, by molding the mixture to form bricks and firing the bricks to a temperature of at least 1700ºC, characterized in that the sintered magnesia is used with a portion of 2 to 10% by weight, based on the mixture, with the grain size of up to 0.1 mm, having at least 70% of This portion has a grain size of less than 0.06 mm, because the chrome ore is used in the mixture in an amount of 26 to 56% by weight, and both in a coarse grain of 0.5 to 5 mm, of preferably 0.7 to 2 mm, in an amount of 10 to 40% by weight of the chrome ore, as well as a fine grain of up to 0.1 mm in an amount of 90 to 60% by weight of the chrome ore and the proportion of this grain being less than 0.06 mm at least 70% by weight, because the cooking of the bricks are carried out at a temperature of 1700 to 1900ºC, preferably 1700 to 1850ºC.
