ABSTRACT:
A channel structure, i.e. iron trough or iron runner, for flow of molten pig iron during tapping of a blast furnace, comprises a wear lining which provides the surface along which the iron flows, a permanent lining outside the wear lining and an outer lining of high thermal conductivity outside the permanent lining. The outer lining has a bottom wall and two opposed side walls thermally connected at their lower ends to the bottom wall. To improve resistance to thermal stress, outside and adjoining at least one, but not all, of the walls of the outer lining, there is at least one refractory insulating lining layer, and the other or others of the walls of the outer lining are thermally coupled to heat dissipating means.
