The present invention provides a new and improved refractory brick that provides many distinct advantages over prior art bricks. More particularly, the brick of the present invention facilitates the construction of an integral furnace lining that prevents the dislodgement or movement of individual bricks. The refractory brick of the present invention also provides a continuous refractory lining which affords improved lining lifetimes or furnace campaigns. Each brick comprises a refractory portion and a pair of steel portions. The steel portions are each contained within a recess formed along each of the major surfaces of the brick. The brick is utilized to form a refractory lining within a vessel wherein at least a part of the refractory portion of each brick is in contact with the refractory portion of adjoining bricks and the steel portions of each of the bricks is metallurgically bonded to the steel portions of adjoining bricks so as to provide an integral (monolithic) refractory wall.
A refractory brick for use in forming a lining for a vessel comprising a refractory portion and at least two sections of steel, said refractory portion having a first major surface and an opposed second major surface, each of said major surfaces includes an outer wall encompassing a recessed portion, said recessed portion comprising a bottom wall and a side wall extending between said bottom wall and said outer wall, said recessed portions each containing one of said sections of steel, said sections of steel each having a first major face and an opposed second major face, said first major faces of said steel sections being in contact with the bottom walls of said recessed portions, said side wall and said outer wall forming a boundary surrounding the entire perimeter of said steel section wherein said side wall is of sufficient thickness to substantially prevent oxidation of protected steel and said second major faces of said steel sections being substantially contiguous with the outer walls of said refractory portions.
A method of producing a refractory brick comprising the steps of:
A device for high temperature processing having a vessel, said vessel including a refractory lining comprising a first and a second refractory brick, said bricks each having a refractory portion and a steel portion, said steel portion being contained within a recess formed along a major surface of said bricks such that said bricks provide a continuous refractory inner lining, at least a part of said refractory portion of said first brick and at least a part of said refractory portion of said second brick being in contact, and said steel portion of said first brick and said steel portion of said second brick being joined by a metallurgical bond wherein each of said bricks further provide a side wall surrounding the entire perimeter of said steel section contained within a recess of said major surface of said bricks and said sidewall is of sufficient thickness to substantially prevent oxidation of protected steel.
A method of producing an integral refractory lining for a vessel comprising the steps of:
