Method for intensively producing refractory material binder by coal tar pitch needle coke

The invention discloses a method for intensively producing a refractory material binder by coal tar pitch needle coke, comprising: separating, settling, purifying, oxidizing and modifying the QI1 residue which is not utilized in the prior art, coal tar, byproduct oils of a delay coking tower, a conditioning agent and a nickel, vanadium and cobalt depriving agent, to obtain the refractory materialbinder with high softening point, high slagging resistance, high oxidizability and high thermal shock resistance, mixing the refractory material binder with the activators: white carbon black, ammonium humate, polyvinyl alcohol, carboxymethyl cellulose, etc., and dry-pressing and forming the mixture to obtain the refractory material for a steel furnace with the performance batter than that of thephenolic resins. The refractory material binder is dissolved in the solution of carbon black, xylene, coumarone, polyethylene glycol, etc., to obtain a liquid spray coating type binder for repairing the steel furnace, which has higher repairing intensity than the common medium temperature asphalt does. The refractory material binder can effectively prolong the service life of a converter, an electric furnace, a calciner, etc.
