This equipment is specially designed for precious metal refining research and development of industrial furnace. It is the last working procedure of noble metal hydroreduction process, which requires very high environmental cleanliness in heating area and does not allow any impurities to pollute raw materials. Because the material contains a small amount of HCL, 316L corrosion-resistant stainless steel material can be used in the inner liner of the equipment, and imported materials can also be used (high price, long cycle).
1. Charging; 2. Vacuum and nitrogen gas washing furnace; 3. Heating up temperature; 4. Heat preservation and constant temperature using material heat balance; 5. Heating up temperature; 6. Heat preservation and constant temperature; 7. Nitrogen gas cooling and washing furnace; 8. Opening up and discharging.
The equipment has the functions of improving the purity of precious metals (platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), iridium (Ir), surface brightness and removing trace impurities.
The device is a side door front charging structure, which is convenient for the switch to take and discharge materials. It includes inner liner and loading tray, temperature control system, heating system, thermal insulation system, temperature measurement system, air supply system, vacuum system, overpressure safety protection system, cooling and cooling system, etc.
