ABSTRACT:
In order to move a furnace body (1) and a furnace lid (2) relative to one another by approximately one furnace body width, the separating surfaces of the furnace body (1) and furnace lid (2) are inclined relative to the horizontal.
The direction of movement when the furnace body (1) is moved then runs in the direction of the angle opening and, when the furnace lid (2) is moved, the movement is in the opposite direction.
In order to reduce the frictional forces between the separating surfaces (4, 5) of the furnace body (1) and furnace lid (2) and to ensure that the relative movement of the furnace body (1) and the furnace lid (2) occurs under defined conditions, the furnace lid (2) is supported on at least two support points on the furnace body (1) on which roller tracks (6) are arranged together with support rollers (7) which roll on the tracks for a certain travel. When opening the furnace body (1) and furnace lid (2), the weight of the furnace lid (2) is by this mechanism first partially, then completely transferred to the lid carrying and swivelling device (10, 42) and, when closing the furnace body (1) and furnace lid (2), the weight of the furnace lid (2) is similarly first transferred partially and then completely transferred to the furnace body (1).
