Equipment Introduction:

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).
Technological process:
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.
Usage function:
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.
Equipment structure:
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.

Material tray

3 layers, can be pulled.

Non-porous trays and perforated trays, please specify when ordering.

Temperature control system

9 inch touch screen instrument

30-segment PID program freely set

Temperature control accuracy ± 1 ° C

With over temperature alarm, data storage, data export function

When the customer actually needs a larger liner, it is recommended to choose a special furnace with a fan blade on the back, which can make the temperature field inside the liner better.

Heating system

HRE Beijing Shougang Electric Wire

Heating the wire cloth on the outside of the liner

Temperature uniformity ± 8 ° C

Optional imported heating wire (Contel A1, Sweden).

Insulation system

1500 polycrystalline fiber insulation board

Temperature measurement system

K type thermocouple

Gas supply system

The float flowmeter 1 range can be selected as needed.

After the gas is connected, the pipe enters the bottom of the tank, and the two ports are located before and after the tank.

Customers are advised to purchase a good mix of hydrogen and nitrogen.

The ratio is 97% N2 and 3% H2.

If you can't buy it, you can choose two proton flowmeters and two flow controllers.

The amount of intake air is different for each customer's process requirements. Please specify when purchasing.

If the intake air volume is too large, it will affect the furnace temperature field, then you need to choose a gas preheating device.

Vacuum system

VRD-4 vacuum pump 1 set

KF25 vacuum flapper valve 1

KF25 vacuum bellows 1

KF25 clamp 2

Optional imported vacuum pump (Germany Leybold D8c, UK Edward, etc.)

Optional oxygen content analyzer.

Overpressure safety

Protection system

SMC Japan imported vacuum pressure adjustment switch

When the gas pressure in the furnace exceeds 0.02 MPa, the SMC automatically works to discharge the gas.

When the temperature is lower than 0.02 MPa, the exhaust gas is stopped.

Cooling and cooling system

CW-3000 chiller 1 set

Non-standard order

According to the needs of customers, we can customize the equipment to meet the needs.
