<p>The present invention proposes a method for constructing a support ring in a curved wall, in particular around an opening in a curved wall of a hot blast stove, wherein the method comprises providing a plurality of standardised wedge-shaped bricks (12, 14, 16, 18, 20, 22) with side faces (32, 34) having tongue and groove profiles (36, 38) for cooperating with the side faces of the neighbouring bricks, the thickness (T) of the brick in the axial direction being in excess of the desired end thickness (t) of the brick. The method comprises determining the intended location of each individual brick in the curved wall and determining, based on the intended location, the location of a front cut line (56) and a rear cut line (58) for shaping the front and rear faces (24, 26) of the brick. The front and rear faces (24, 26) of the brick are then shaped in accordance with the above determined front and rear cut lines (56, 58) by means of a cutting tool.</p> |
