Method of preparing a hearth roll with a coating
 A method of preparing a hearth roll with a coating, including: plating a metal on a ceramic powder by using electroless plating; mixing the metal-plated ceramic powder and a metal powder to form a cement powder; and thermally spraying the cement powder onto a hearth roll. Another method is: plating a metal on a ceramic powder by using electroless plating; mixing the metal-plated ceramic powder, a metal powder, and a binder to form a slurry, and subjecting the slurry to granulating and sintering to obtain a sintered powder; and thermally spraying the sintered powder onto a hearth roll.
