An increase in the coke residue of normally employed coal-tar bond substantially increases the concentration of residual carbon in tardolomite refractories, and improves their density and strength in the coked state. There is also a large increase in the resistance of the tar-dolomite refractories in the converter linings. The production of tardolomite refractories by pressing from cooled bodies should be done with soft tar with a coke residue of at least 38%. The temperature of the body during fabrication should then be selected in accordance with the viscosity of the bond. In particular, using tar with a viscosity of C=35-60 sec, the temperature of the body during pressing should be 35-45°C. [ABSTRACT FROM AUTHOR] |
