ABSTRACT OF THE DISCLOSURE The invention relates to a wear lining structure of a converter. According to the invention, unburned carbon- bonded bricks comprising 3-40 weight % of a carbonaceous material, 1-10 weight % aluminum, and magnesite clinker for the residual part, are used for at least part of the wear lining in order to enable the wear lining structure of a converter to stand various severe thermal load conditions imposed on the wear lining refractories in a B.O.F. steel making process operated in various forms, such as an oxygen top-blown process, as oxygen bottom-blown process, and com- binations thereof, and the like, thereby to provide the wear lining structure of a converter capable of standing a long-range use even under the said severe thermal load con- ditions.
