A graphite-containing monolithic refractory material comprises at least one component selected from alumina and alumina-magnesia spinel, which are divided into selected particle size regions, artificial graphite having a selected average particle size, and pitch powder. The refractory material may optionally comprise a selected amount of silicon carbide having a selected average particle size. The graphite-containing monolithic refractory material exhibits excellent casting workability at a low moisture content, and both excellent corrosion resistance and spalling resistance. The refractory material is suitable as a casting monolithic refractory material for lining a topedo ladle car.

A repairing material for the bricks of the carbonizing chamber in a coke oven is obtained by compounding mortar as a main component with a powder comprising 70-100 wt. % of a Co compound, Ni compound, and/or Al compound and 0-30 wt. % of at least one compound selected from among the compounds of Ca, Mg, Zn, Sr, Ba, Fe, V, Pb, Cu, and Ti, and a liquid formed of water, B, P, and at least one member selected from among Si, Na, and K. A method for repairing includes hot applying the repairing material to portions of the bricks of the carbonizing chamber in the coke oven which are in need of repair.
