The present invention relates to a method for manufacturing a refractory erial having numerous through pores in a certain direction. The refractory material is manufactured by covering a woven fabric composed of combustible weft and/or warp threads with a slurry of a refractory material, and then drying and baking the coated fabric to burn out the combustible yarns so that the desired through pores may be obtained in directions corresponding to the direction of the burned out weft and warp threads.

Method for manufacturing refractory material having numerous through

A method and apparatus for repairing lining which comprises transmitting microwaves modulated by an antenna inserted into the vessel to the surface of the heated refractory lining in the refractory lined vessel, detecting the reflected waves, detecting the difference between the reference surface of the refractory lining and the damaged surface from the phase difference of the microwaves, controlling the transfer of the refractory gunning nozzle inserted into the vessel with the use of the deviation signal, and making the lining repair in the hot atmosphere.
