Supporting device for blast-furnace hot-blast main

摘要

The ends of hot-blast air main hangers are connected to a carrying beam through the medium of pre-compressed springs, preferably each of the springs is in the form of a set of disk springs. The precomposition force of these springs is substantially equal to the mass of a section of the hot-blast main supported by the carrying beam. The magnitude of the pre-compressed setting of the springs is several times larger than the maximum displacements of air heater connecting pipes when the air heaters are vertically displaced during their operation.
