Abstract

The present invention concerns a method for creating a thermally stable base structure which may form part of furnaces and means in connection with such a method. In particular, the present invention concerns base structures which may form part of ring furnaces for calcining of carbon blocks for use in aluminium electrolysis. The base structure rests on a foundation consisting of a number of columns (15, 16, 17, 18, 19, 20) and is created by a first layer B' of refractory bricks being laid on the foundation. These bricks are made with locking elements (25, 26) on their tops, onto which is laid a second layer C' of refractory bricks with equivalent, complementary locking elements underneath them. In this way, the two layers are connected to each other and a structure is achieved which has proved stable in relation to thermal and mechanical loads.
