AI Technical Summary
During operation, the radiant furnace tubes may deform or be damaged due to thermal expansion. Existing installation methods cannot effectively support the expansion of the furnace tubes, resulting in stress concentration.
A stable radiant section furnace tube was designed. Through the combined use of support components and buffer components, including fixing blocks, fitting blocks, loosening components and buffer components, and with the cooperation of springs and screws, the furnace tube is allowed to move during expansion, avoiding obstruction of the expansion part.
This provides stable support for the furnace tubes during the expansion process, avoiding deformation or damage caused by stress concentration and improving the service life of the furnace tubes.

Abstract
Claims
1. A support-stabilized radiant section furnace tube comprising a refractory plate, a furnace tube body, characterized in that: The refractory plate is equipped with a support component to reduce local deformation and damage to the furnace tube body; The support assembly includes a fixing block, on which a fitting block for supporting the furnace tube body is attached, and a loosening assembly for preventing the expansion of the furnace tube body is installed on the fitting block. A crossbar is provided on the bonding block, and a sleeve that is easy to adjust is fitted on the crossbar. Two buffer components for reinforcing and supporting the furnace tube body are installed on the outer wall of the sleeve.
2. The support-stabilized radiant section tube according to claim 1, characterized in that: The loosening assembly includes a protrusion fixed to the top of the fixing block. A translation rod for translational movement is provided on the protrusion. One end of the translation rod is connected to a connector used for fixing the bonding block, and the other end is connected to a connecting plate. The connecting plate and the protrusion are connected by a first connecting spring.
3. The support-stabilized radiant section tube according to claim 1, characterized in that: An additional block is provided on the bonding block, and a first connecting screw for connecting the connector is provided on the additional block.
4. The support-stabilized radiant section tube according to claim 1, characterized in that: The buffer assembly includes a first arc-shaped plate, on which a second arc-shaped plate supporting the furnace tube body is disposed, and the second arc-shaped plate and the first arc-shaped plate are connected by a second connecting screw.
5. The support-stabilized radiant section tube according to claim 4, characterized in that: The second arc-shaped plate is provided with a bonding piece that fits the furnace tube body. A T-shaped block is installed on the bonding piece. The T-shaped block is connected to the second arc-shaped plate by two second connecting springs.
6. The support-stabilized radiant section tube of claim 2, wherein: A limiting block is installed on the left side of the protrusion to restrict the movement space of the connecting plate.
7. The support-stabilized radiant section tube according to claim 2, characterized in that: The right side of the connector is provided with a threaded through hole with the same diameter as the first connecting screw.
