Embodiment 1
[0022] Sand core molding step: fill the quartz sand with a particle size of less than or equal to 400 meshes into the housing 20 of the fuse with the fuse 10, add an appropriate amount of absolute ethanol, and vibrate the housing 20, and the quartz sand in the housing 20 The sand is shaken evenly and compacted, and then, the housing 20 is heated under a gas lamp or an alcohol lamp to remove absolute ethanol in the housing 20 . The quartz sand in the casing 20 is bonded and molded into the sand core 1 . Add absolute ethanol and 5% to 8% of the mass of quartz sand during the sand core forming process.
[0023] Steps for forming the inorganic gelling agent: use silicon powder with a particle size of less than or equal to 1000 mesh as the binder, and the silicon powder belongs to a type of amorphous silicon dioxide. The silicon powder with particle size less than or equal to 1000 mesh is fully dissolved by adding absolute ethanol, and the silicon powder / absolute ethanol saturated...

[0027] Sand core molding step: fill the quartz sand with a particle size of less than or equal to 400 meshes into the housing 20 of the fuse with the fuse 10, add an appropriate amount of absolute ethanol, and vibrate the housing 20, and the quartz sand in the housing 20 The sand is shaken evenly and compacted, and then, the housing 20 is heated under a gas lamp or an alcohol lamp to remove absolute ethanol in the housing 20 . The quartz sand in the casing 20 is bonded and molded into the sand core 1 . Add absolute ethanol and 5% to 8% of the mass of quartz sand during the sand core forming process.
[0028] Steps for forming the inorganic gelling agent: choose sodium silicate as the binder, add the sodium silicate into deionized water to fully dissolve it, and prepare an aqueous solution of sodium silicate as the binder solution. The mass percent concentration of the sodium silicate aqueous solution is 3-8wt.%. The shell 20 of the fuse and the sand core 1 are immersed in th...
