摘要: The present invention relates to an injection material for the hot repairing of a blast furnace and an injection method of applying the same. An injection material comprising a refractory material, which was previously adjusted in particle size, a binder, a hardening agent and a hardening-accelerator is fed to a pressure pump having a mixing function and applied to a portion to be repaired of a blast furnace with mixing in said pump. Thus, since the hardening ingredient is not added until the pump portion, the workability of the repair material can be secured in of a blast furnace to be repaired, said injection material being mixed in said pump. Thus, the injection repairing of the blast furnace can be achieved without being influenced by an atmosphere within the furnace.

摘要: Disclosed is a monolithic refractory comprising 1 to 30 weight parts of pitch having 65 to 90 wt.-% of fixed carbon and a softening point of 250.degree. to 350.degree. C. to form a carbon bond, relative to 100 weight parts of refractory material so as to form carbon bond. The monolithic refractory can contain 0.01 to 0.5 weight parts of carbon fiber. The composition of the invention may be used as any type of monolithic refractory such as gunning material, casting material, in particular, aqueous type casting material, burning type hot repairing mix, mortar, Tamping material, and any basic, neutral, or acid refractory material may be used. The monolithic refractory is capable of solving the drawbacks of the conventional monolithic refractories such as rupture, lack of low shrinkage, low bonding strength, low hot strength, and having both superior strength and superior applicability.
