XTL Sinytron The manufacturer of magnesia cupel

Magnesia cupel is a type of vessel used in the process of assaying precious metals such as gold and silver. Made from a special type of magnesia-based material, the cupel is designed to withstand high temperatures without melting or reacting with the metals being tested.During the assaying process, the magnesia cupel is placed in a furnace along with the metal sample. As the temperature rises, the cupel absorbs any impurities or base metals present in the sample, leaving behind only the pure gold or silver.

Once the assaying process is complete, the magnesia cupel is carefully removed from the furnace and allowed to cool. The cupel is then cracked open to reveal the precious metal bead that has formed inside. This bead is then weighed and analyzed to determine the purity and quality of the metal sample. 

Overall, the magnesia cupel plays a crucial role in the assaying process, providing a reliable and accurate method for determining the purity of precious metals.

The main component of magnesia cupel:
The main component of magnesia dust pan is magnesium oxide, which is a high-temperature material with good thermal insulation and thermal insulation properties. Magnesium oxide is divided into two types: light magnesium oxide and heavy magnesium oxide. Light magnesium oxide has a small specific gravity and low melting point, while heavy magnesium oxide has a high density and good corrosion resistance. In order to improve the performance of magnesium oxide, other materials are added to the magnesite gray pan, such as magnesite, ductile iron, etc. In addition, some magnesia ash dishes will also add special fluxes, such as special fluxes with a content of up to 4%.
Magnesia cupel production process flow:
The production process of magnesia gray pans can be designed and adjusted according to specific production requirements and process flows. The following is an example of a general magnesia gray pan production process flow: 1. Raw material preparation: Collect the required raw materials, including magnesia powder, binder and mold. 2. Mixing and proportioning: Mix magnesium powder and binder together in a certain proportion to ensure even distribution. 3. Mold filling: Pour the mixture into the mold used to make the gray dish, making sure it is evenly filled and compacted. 4. Mold vibration: Shake or vibrate the mold to eliminate gaps and improve the tightness of magnesia. 5. Drying: Place the filled mold into a drying chamber to remove moisture and allow the gray pan to form a stable structure. 6. Demold: After the gray dish is completely dry, take it out of the mold, taking care to keep the shape intact. 7. Refinishing and Refinishing: Surface refinishing and repairing of gray dishes to ensure a smooth and defect-free appearance. 8. Roasting: Place the ash pan in a high-temperature furnace for roasting to achieve the required hardness and heat resistance. 9. Cooling and processing: Cool the fired ash dish and perform necessary processing and decoration, such as glazing, painting, etc. 10. Quality inspection and packaging: Carry out quality inspection on the finished gray dishes to ensure that they meet the requirements before packaging and leaving the factory. Please note that this is just an example process flow and actual conditions may vary depending on different manufacturers, product requirements and process technologies. Detailed process flow should be designed and adjusted according to specific circumstances and requirements.
