The application discloses a high-tensile super-strong prefabricated part for a boiling calcining furnace and a manufacturing method thereof, and relates to the technical field of calcining furnaces. The prefabricated part comprises a plurality of prefabricated part bodies, at least one anchor is embedded in the interior of each prefabricated part body, and one end of the anchor extends out of the back of the prefabricated part body to form a connecting part for connecting with a furnace shell. By embedding the anchor in the interior of each prefabricated part body, the traditional connecting mode of externally welding the anchor is replaced, meanwhile, the anchor and the prefabricated part body are combined into an integrated whole in the prefabricating stage in the factory, and the interface gap between the traditional welded anchor and the refractory lining is effectively eliminated. Meanwhile, the plurality of prefabricated part bodies are detachably connected to form a modular structure, which not only facilitates the quick installation of the prefabricated part, but also enables the single replacement of the damaged prefabricated part body without large-area furnace shutdown and maintenance, thereby avoiding the shutdown loss caused by the overall replacement of the traditional lining when the lining is totally invalid.

This invention relates to the field of thermal energy-saving technology for water beam systems at the bottom of heating furnaces, and particularly to a multi-layer composite insulation structure for water beam columns in heating furnaces. The structure includes anchor hooks staggered and fixed to the outer surface of the water pipes on the water beam columns, and insulation layers. From the inside out, the insulation layers consist of a first refractory insulation layer, a second refractory insulation layer, a metal mesh temperature-sensitive compensation layer, a castable working layer, a third refractory insulation layer, and metal-glass clamps fastened to the surface of the third refractory insulation layer. The third refractory insulation layer, fastened by the metal-glass clamps, has a sprayed coating working layer on its exterior. The anchor hooks are jointly covered by the first and second refractory insulation layers, the metal mesh temperature-sensitive compensation layer, and the castable working layer, with a thermal bridge blocking sleeve fitted at their ends. The material densities of the first and second refractory insulation layers and the thermal bridge blocking sleeve decrease in a gradient, forming a gradient density insulation structure.
