CATHAY gold melting furnace, high temperature and precise temperature control, efficient gold melting, guaranteed purity

CATHAY gold melting furnace: high-temperature precision melting, the core equipment for gold processing

1. Efficient heating principle to achieve rapid melting of gold

CATHAY gold melting furnace adopts induction heating or resistance heating technology to achieve efficient melting of gold by converting electrical energy into thermal energy. The induction heating type gold melting furnace uses a high-frequency alternating magnetic field (frequency 10-50kHz) to generate eddy currents inside the metal gold, causing the gold to heat itself and quickly heat up to the melting point (1064℃); the resistance heating type uses high-temperature resistant heating elements (such as silicon molybdenum rods and graphite rods) to generate high-temperature radiation, causing the gold to absorb heat and melt. The furnace cavity is constructed with materials with excellent thermal insulation properties (such as alumina fiber and mullite bricks), with a heat loss rate of less than 15%. It can heat 10-500g of gold from room temperature to a molten state within 5-15 minutes, and the melting efficiency is more than 95%, meeting the needs of gold processing of different scales.

2. Multi-scenario adaptation, covering the entire process of gold processing

Jewelry processing field: In the production of gold jewelry, the CATHAY gold melting furnace can melt gold bars and gold nuggets for casting jewelry blanks. For example, 100g of gold raw materials with a purity of 99.9% are placed in the furnace, the temperature is set to 1100℃, and the melting can be completed in 8 minutes. After casting, the purity of the blank remains above 99.9%, without impurity pollution, ensuring the purity and color of the finished jewelry, and meeting the strict requirements of the jewelry industry for gold quality.

Gold recycling and purification: Suitable for the recycling, melting and purification of old gold jewelry and industrial waste gold. In the process of recycling old gold, the gold melting furnace can melt gold of different colors (such as 18K, 24K) separately, remove impurities by adding purifiers (such as borax), and increase the purity of gold to more than 99.9%. The anti-oxidation design of the equipment (inert gases such as argon can be introduced) can reduce the oxidation loss of gold during the melting process, and the loss rate is controlled within 0.1%, thereby improving the recycling efficiency.

Scientific research and experimental research: used for gold alloy ratio experiments and performance tests. In the alloy experiment of gold and other metals (such as silver, copper, and zinc), the melting furnace can accurately control the melting temperature (1064-1300℃) and the holding time (5-30 minutes) to ensure that the alloy components are evenly mixed. For example, in the preparation of 18K gold alloy (containing 75% gold, 15% silver, and 10% copper), the metal is fully fused through precise temperature control, and the alloy performance is stable, providing reliable experimental samples for the research of gold materials.

Industrial gold processing: Gold materials (such as gold wire and gold foil) used in the electronics industry and aerospace fields can be melted and recast. In the production of electronic gold wire, gold is melted and drawn into gold wire with a diameter of 0.02-0.1mm through a wire drawing die. The stable temperature control of the gold melting furnace (temperature fluctuation ≤±5℃) can ensure the consistency of the fluidity of the gold melt and improve the processing accuracy and quality of the gold wire.

Coin casting field: used for the casting production of gold coins and gold bars. When casting gold bars, the gold melting furnace can melt a large amount of gold (such as 500g) and pour it into the mold to form it. By controlling the cooling rate, the gold bar structure is uniform, the surface is smooth, and there are no defects such as pores and cracks, which meets the specifications of gold products in the financial field.

3. Performance advantages to ensure efficient and high-quality gold smelting

Precise and stable temperature control: Adopting an intelligent temperature control system, the temperature adjustment range is 500-1500℃, and the temperature control accuracy is ±1℃. It can display the temperature in the furnace in real time and automatically adjust the heating power to avoid gold volatilization due to excessive temperature (gold boiling point 2808℃) or incomplete melting due to insufficient temperature. For example, when casting gold, the temperature is stably controlled at 1080℃ to ensure that the gold melt has the best fluidity and the casting effect is good.

Reduce gold loss: The inner wall of the furnace cavity is made of high-purity graphite or ceramic material, which does not react chemically with gold to prevent gold from being contaminated; inert gas (such as nitrogen, argon) can be introduced during the heating process to prevent gold from oxidizing to form gold oxide (Au₂O₃), and the melting loss rate is ≤0.1%, which is much lower than the traditional gold melting equipment (loss rate 0.3%-0.5%), which reduces gold loss for users and improves economic benefits.

Convenient and intelligent operation: Equipped with a 7-inch touch screen operation interface, you can intuitively set parameters such as temperature and heating time, support 10 groups of commonly used smelting program storage (such as "24K gold melting" and "18K alloy melting"), and one-click call can automatically complete the heating, insulation, stop and other processes without manual supervision, reducing the difficulty of operation, even novices can quickly get started.

Reliable safety performance: Equipped with multiple safety protection devices - heating cannot be started when the furnace door is not closed tightly to prevent high temperature radiation from hurting people; when the temperature in the furnace exceeds the set upper limit (such as 1500℃), the power will be automatically cut off and an alarm will be issued; the equipment shell adopts a heat-insulating design, and the surface temperature is ≤50℃ to avoid burns to operators; the circuit system is equipped with leakage protection and overload protection to ensure the safety of electricity use.

4. Structural design, taking into account durability and practicality

The furnace body is sturdy and durable: the furnace shell is welded with high-quality cold-rolled steel plates, and the surface is treated with high-temperature paint, which is corrosion-resistant and anti-oxidation, with a service life of more than 10 years; the heating element (induction coil or resistance rod) is made of high-temperature resistant materials, with a continuous service life of ≥1000 hours, reducing the frequency and cost of replacement.

Furnace chamber specifications are diverse: Furnace chambers of different capacities (10ml-500ml) are provided to meet different smelting volume requirements - small furnace chambers are suitable for melting 10-50g of gold (such as jewelry processing), and large furnace chambers can melt 100-500g of gold (such as gold bar casting). The furnace chamber can be disassembled and cleaned, which is convenient for removing residual metal slag, keeping the furnace clean, and avoiding cross contamination.

Efficient heat dissipation system: forced air cooling or water cooling system is adopted to ensure that the temperature of the equipment is stable during long-term operation. The air cooling system discharges heat through a silent fan with a noise level of less than 60 decibels; the water cooling system is suitable for high-power gold melting furnaces, with high cooling efficiency, which can quickly take away the heat of the furnace body and ensure continuous operation of the equipment (can work continuously for more than 8 hours).

Combination of portable and fixed: small gold melting furnaces (weight ≤20kg) are designed with handles for easy movement, suitable for door-to-door gold recycling and other scenarios; large gold melting furnaces adopt a fixed design and are equipped with universal wheels, which are convenient for moving and positioning in the workshop to meet the needs of different working environments.
