Precious Metal Smelting Furnace For Non- Ferrous Metal Smelting

Precious metal melting furnace is a professional equipment used for melting precious metals such as gold, silver, platinum, palladium, etc. The following is its related introduction:

Working principle
Resistance heating type: generates heat through heating elements such as resistance wires or resistance strips, converts electrical energy into thermal energy, and causes precious metals in the furnace to reach their melting point and melt. This method heats uniformly and controls the temperature accurately, effectively reducing the oxidation and loss of precious metals.
Intermediate frequency induction heating type: using intermediate frequency alternating current to generate an alternating magnetic field through an induction coil, causing precious metals in the magnetic field to produce induced current, thereby generating heat to achieve melting. Its advantages are fast heating speed, high efficiency, precise temperature control, and minimal thermal radiation to the environment.

Structural characteristics
Furnace body: It is usually made of materials that are resistant to high temperatures and corrosion, such as ceramic fibers, corundum, etc., to ensure structural stability and sealing at high temperatures and reduce heat loss.
Heating system: Equipped with corresponding heating elements or induction coils according to different heating methods. Heating elements need to have good insulation and high temperature resistance, while induction coils need to have high electromagnetic induction efficiency.
Temperature control system: high-precision temperature sensors are used to monitor the temperature inside the furnace in real time, and the heating power is precisely adjusted through a temperature controller to ensure that the temperature is controlled within the set range. Generally, the temperature control accuracy can reach ± 1 ℃ or even higher.
Melting crucible: used to hold precious metals, usually made of high-temperature resistant materials such as graphite and quartz that do not undergo chemical reactions with precious metals. The shape and size of the crucible are determined according to the specifications and production needs of the melting furnace.
Stirring device: Some precious metal melting furnaces are equipped with stirring devices, such as electromagnetic stirrers or mechanical stirrers. The stirring device can evenly mix precious metal liquids, improve melting quality, and help accelerate heat transfer and chemical reactions.

Performance advantages
High precision temperature control: capable of meeting the strict temperature requirements for precious metal melting, ensuring the purity and quality stability of precious metals. For example, in the process of gold smelting, precise temperature control can avoid problems such as impurity mixing or gold oxidation caused by high or low temperature.
Efficient and energy-saving: The medium frequency induction heating melting furnace has a higher heating efficiency. Compared with traditional fuel or gas melting furnaces, it can significantly reduce energy consumption, shorten melting time, and improve production efficiency.
Environmentally friendly and clean: Resistance heating and medium frequency induction heating methods do not produce combustion exhaust gas during operation, making them environmentally friendly. Meanwhile, due to the relatively closed heating process, it can effectively reduce the emission of precious metal dust and improve the working environment.
High degree of automation: It can be equipped with an automated control system to achieve automated operations such as feeding, melting, and discharging, reducing manual intervention, improving production stability and consistency, and reducing labor intensity and human error.
