Abstract
The invention discloses a fiber cavity radiating element on the inner surface of a furnace composed of refractory materials such as ceramic fiber modules, pouring materials, and ramming materials and a manufacturing method thereof, which includes the following steps: (1) forming the fiber cavity radiating element Put the material into the container, pour in the binder, and continuously stir the material in the container through the mixer; (2) Turn on the vacuum pump to make the vacuum tank in a negative pressure state, and then put the mold connected to the tank into the container , and then open the hydraulic device; (3) when the liquid is injected into the vacuum tank, open the water discharge valve and the pressure regulating system, and put the water in the vacuum tank back into the container; (4) put the components sintered to form fiber ceramics into the Wet the bottom, interior and exterior of the component in a container containing the two-component paint. The invention can adjust the density of the fiber cavity radiation element and the bonding force between materials according to the vacuum pressure, has high productivity, and ensures the light weight and service strength of the element.
Description
technical field [0001] The invention is applied to the fiber cavity radiating element on the inner surface of the furnace composed of refractory materials such as ceramic fiber modules, pouring materials, and ramming materials, and a manufacturing method thereof. Background technique [0002] Adding a number of cavity radiation elements on the inner lining surface of the heating furnace is a project that can increase the radiation heat transfer area and increase the emissivity of the furnace lining surface, thereby achieving enhanced radiation heat transfer, improving furnace heat transfer efficiency, and realizing energy saving and reduction. Energy-saving technologies that improve the economic efficiency of enterprises. The application of this technology on the heating furnace in the metallurgical industry has an energy-saving rate of more than 10%, which has brought good economic benefits to users. [0003] At present, the cavity radiation elements used in industrial fur...
