ABSTRACT:
A process for reinforcing porous refractories with fillers, such as carbon particles, is provided. First, filler particles are mixed with a liquid resin to produce a liquid mixture. The mixture is allowed to seep into the pores of the refractory, preferably by immersing the refractory in said mixture in an evacuated tank. The refractory can be removed from the mixture and excess mixture can be allowed to drip from the refractory. The refractory is then cured, preferably by heating. The refractory is strengthened by the process to better withstand heat fluctuations encountered, for example, in the steel refining process.
