ABSTRACT:
To diminish cracking due to differential expansion of refractory channels conducting molten materials, e.g. in an iron runner or iron trough, lateral pressure is exerted inwardly on the wear lining of such a channel through intermediate layers of permanent lining. These may include low friction slide plates and at least one layer having a high thermal conductivity. The means exerting the pressure react against an external frame structure and are preferably such that the pressure exerted is independent of the degree of expansion of the channel.
