Abstract

PURPOSE:To prevent a wedge-shaped joint gap from being formed at a conical part of a converter by a method wherein trapezoidal bricks are piled up at an appropriate inclination angle gainst a converter which has a conical type furnace shell. CONSTITUTION:When constructing a lower part of the furnace body of a converter or the like, the trapezoidal bracks are used which have a fixed thickness (t) and in which the widths (a), (c) on the side of the wall of an iron shell 1 as a viewed in the trhickness direction and the widths (b), (d) on the side of the furnace center are different from each other. When the bricks are placed with the cross-sectional surfaces of the bricks in parallel to the iron shell 1, the difference berween the furnace circumference l' at point A and that l at point B is absorbed by the difference (a-c) of the brick width across the thickness of the brick and, accordingly, the bricks can be placed without generating any gaps therebetween. By using trapezoidal bricks, it is made possible to minimize or completely eliminate joint gaps even in the case of building up the bricks at an inclination angle of alpha against the horizontal line for the iron shell 1. Accordingly, the useful life of the converter can be prolonged greatly.
