Anchorage Force and High-Temperature Stability of Refractory Fiber Modules

Refractory fiber modulesRefractory fiber module are widely used in new or upgraded high-temperature forging furnacesFurnace because of their lightweight, heat-insulating, and heat-retaining properties. The service life and operational efficiency of the furnace is strongly related to the stability of the internal fiber module anchorage structure. We have analyzed the force characteristics of the anchoring structure of refractory fiber modulesRefractory fiber module and established the force equilibrium of the stable and non-dislodging interaction of refractory fiber modulesRefractory fiber module with different anchorage structuresAnchorage structure and its correlation with the preset force F0 provided by the anchoring weld. The shrinkage characteristics of the refractory fiber modulesRefractory fiber module in the anchorage structureAnchorage structure, the stability and oxidation resistance of the anchorage structure, and the pre-positioned weld material to high temperatures are investigated through high-temperature simulationSimulation experiments. Combined with the actual application, we propose the installation layout mode to effectively reduce the high-temperature shrinkage gap between the refractory fiber modulesRefractory fiber module, and optimize the position distribution of the anchored metal structural parts in the refractory fiber anchorage structureAnchorage structure and the anchorage welding adjustment scheme. The optimized scheme was applied to the repair and renovation project of a heating furnaceHeating furnace” in a factory, which achieved significant economic and social benefits.
