An artificial gemstone melting device that prevents the heating device from being corroded

Abstract

The invention belongs to the field of IPC classification C04 artificial stone manufacturing, and specifically relates to an artificial gemstone melting device for preventing the heating device from being eroded, including a melting pool and a heating device. The two sides of the pool mouth of the firing pool are provided with an upper cover plate extending toward the center of the pool mouth, and a heat conduction plate is arranged between the heat insulation cover and the upper cover plate, and the heat conduction plate is located at the edge of the upper cover plate; The upper covering plate on the outer side of the melting pool. The invention melts and burns artificial gem raw materials more uniformly, and the artificial gem quality produced is better, and can prevent the heating device from being eroded, and can also improve the corrosion resistance of the melting pool, thereby prolonging the service life of the melting pool, and can also Avoid structures such as heating devices falling off into the melting pool due to erosion and debris to affect the quality of artificial gemstones.

Description

technical field [0001] The invention belongs to the field of IPC classification C04 artificial stone manufacturing, and in particular relates to an artificial gem melting device for preventing a heating device from being corroded. Background technique [0002] Materials that are entirely or partially artificially produced or manufactured for use in jewelry and decorations are collectively referred to as artificial gemstones, including synthetic gemstones, man-made gemstones, composite gemstones, and reconstructed gemstones. Many man-made gemstones have a high refractive index and dispersion coefficient. After being polished, they have a diamond-like luster and transparency. They can partially replace natural zircon and diamonds to make jewelry. In the process of manufacturing artificial gemstones, the raw materials need to be melted and fired into liquid at high temperature, and the raw materials for manufacturing artificial gemstones are extremely corrosive in a high-temper...

AI Technical Summary

Problems solved by technology

In the process of manufacturing artificial gemstones, the raw materials need to be melted and fired into liquid at high temperature, and the raw materials for manufacturing artificial gemstones are extremely corrosive in a high-temperature liquid state (>1300°C), which is harmful to the melting device and the inside of the melting device. The heating device and its erosion, especially after the heating device is eroded, it is easy to produce debris and fall off, which is melted into the gem raw material for melting, while artificial gemstones have higher requirements for light transmission, color, and luster. The intervention of trace impurities containing transition elements (especially iron) in the outside world (such as the high-temperature skin of the heating element silicon carbide rod, silicon-molybdenum rod or electric heater peeling off into the high-temperature liquid, which contains iron) will reduce the light transmission of the artificial gemstone Sexuality, poor yellow-brown or even opacity will affect the product quality, greatly reduce the value of the artificial gemstones produced, and also cause damage to the heating device
