摘要

Procedure for the manufacture of pastes or anhydrous carbon masses for the construction and repair of furnace crucibles and walls and the lining of channels, routes, etc., and protection thereof, characterized by consisting of mixing a raw material such as coke or the like, preferably dry coke by a suitable procedure such as fixed, rotary driers, stoves, etc., and ground and mixed in roller mills, propeller mixers, vats or the like with deoiled and dehydrated tar, heated to approximately 80ºC. and to which, for certain uses, a certain quantity of silica (sand), alumina (clay), etc. can be added, to obtain a certain elasticity, as well as a chemical hardening reagent that regulates its cracking time or setting time according to needs, said reagent preferably being a compound of phosphorus, sodium or phenolic resins that act by the action of heat at temperatures below 300ºC and in the presence of CO2, independently or together.
