Abstract
The invention relates to the method for hot repairing various kinds of pig iron and steel making furnaces wherein a hot repairing material made in the state of slurry by adding 10-50 weight % water to a monolithic refractory comprising refractory and/or carbon-containing granulated particles and a binder is projected onto a worn part necessitating repairs in the high temperature furnace, the water in the projected hot repairing material boiling under the high heat in the furnace whereby said repairing material is not only fully mixed but also permitted to flow into the minutest recesses of the part necessitating repairs, said repairing material being hardened with the termination of the boiling thereby enabling to form in the worn part a fabricated body having high packing, strength and corrosion resistance.
