Claims11
A backup structure for a pipe for feeding a molten substance of high temperature which comprises a pipe for feeding a molten substance of high temperature and a thermal insulation material surrounding the pipe wherein the pipe is provided with a plurality of projections on its outer periphery at predetermined intervals, and each of the projections is held at its both sides by the thermal insulation material, wherein said thermal insulation material comprises a plurality of stacked bricks, and wherein each projection acts as a boundary for adjacent bricks.
A backup structure for a pipe for feeding a molten substance of high temperature which comprises:
- a solid thermal insulation material arranged around a pipe for feeding a molten substance of high temperature and
- a container for receiving and supporting the solid thermal insulation material wherein the container is partially changeable in the direction of the pipe between a time that the pipe is at an elevated temperature due to passing therethrough a molten substance of high temperature and a time that the pipe is not at an elevated temperature.
A supporting device for supporting a thermal insulation material for surrounding the circumference of a pipe for feeding a molten substance of high temperature which comprises;
- a supporting plate fixed to a lower end of the pipe for feeding a molten substance of high temperature, the pipe being suspended from a housing,
- a solid thermal insulation material arranged around the pipe and placed on the supporting plate, and
- a push-up means which connects the supporting plate to the housing and forces upwardly the supporting plate to support the thermal insulation material, whereby an expansion force of the pipe and the thermal insulation material is released downwardly against an urging force of the push-up means.
