This refractory system is connected with metallurgical benefits such as high oxidic stability of its oxides, and the ability to bond sulfur from the hot metal. Production and application of carbon-bonded refractories is directly linked with environmental harmful emissions in the broadest sense. In the center of this work is the aspect of increased residual carbon content of the binder resin due to TiO2 addition. Furthermore, this work has observed the applicability of TiO2-treated bricks in AOD converter. The increased residual carbon content of the binder resin connected with improved mechanical, physical, and thermomechanical properties due to sub-micro scaled TiO2 and metallic antioxidant addition offers the feasibility to reduce the total carbon content without downgrading the brick properties. This aspect has not been observed yet, and is of high interest with respect to reduced emissions and environmental friendly refractories. Previous works have investigated the influence of TiO2 on other carbon-bonded refractory systems, such as alumina carbon and magnesia carbon. As illustrated in this work and previous work, TiO2 is working completely different in the doloma carbon system when compared with other systems.
