Abstract
A method for increasing the durability of refractory linings in vessels having inclined areas or conical parts in their inside contour includes in fitting the refractory bricks obliquely following the inside contour of the vessel. The slant of the bricks is brought about step by step by several layers of machine-pressable turning bricks of known uniform density. This method makes it possible to obtain softer transitions from the horizontally laid bricks to the obliquely laid bricks.
