Abstract
The device is adapted to avoid the drawbacks of conventional arrangements including tie-rods and tensioners and in particular ensure a correct centering of the nozzle relative to the heel of the tuyere. The device comprises mainly a support fixed to the casing of the blast-furnace which defines slideways in which there is received a plate rigid with the lower cone of the blast downpipe. Means are provided for rendering the cone rigid with its support before disassembly. These means are withdrawn in normal operation.
