Brannprøveovn
A fire test furnace is primarily used in the fire assay process for precious metal analysis, suitable for detecting and analyzing the content of metals such as gold and silver.
The equipment melts the sample at high temperatures, causing the precious metal to react with and separate from the flux, thus completing the enrichment and determination process. It is commonly used in geology, mining, metallurgy, and testing institutions, and is a fundamental piece of equipment in fire assay experiments.
Produktfunksjoner (Brannprøveovn)
- Fire Assay Process Design
The furnace chamber dimensions are designed to accommodate the placement of assay crucibles and ash blowing dishes, allowing for simultaneous processing of multiple samples and improving analytical efficiency. The heating profile and holding time can be precisely controlled, meeting the stringent temperature profile requirements of fire assays.
- High-Quality Furnace Lining, Resistant to Rapid Heating and Cooling
The furnace lining is made of vacuum-formed high-purity alumina lightweight material, offering advantages such as resistance to rapid heating and cooling, crack resistance, and slag resistance, making it durable and resistant to damage over long-term use. High-impact areas for material handling (furnace opening and bottom) utilize lightweight hollow spherical alumina plates for enhanced durability.
- Complete Supporting Equipment
We provide supporting equipment such as ash hoppers, scrapers, crucible supports, crucible tongs, and ventilation systems, supporting complete system integration and providing a complete fire assay solution for laboratory testing.
- Observation Port Design for Easy Monitoring
The furnace door is equipped with an observation port, allowing operators to monitor the melting state of the crucible or the ash blowing process in real time without opening the door, thus minimizing heat loss.
- Electric and Pneumatic Top-Opening Door with Foot Switch Control
The furnace door uses a top-opening mechanism that combines electric and pneumatic operation, and is equipped with a foot switch to control the opening and closing height.

Ofte stilte spørsmål (FAQ)
- What is a Fire Test Furnace?
A fire test furnace is a high-temperature heating device specifically designed for the analysis and testing of precious metals (gold, silver, platinum, palladium, etc.). It is mainly used for pyrometallurgical analysis of precious metal content in samples such as ores, alloys, and waste.
- How does a fire test furnace differ from a regular high-temperature furnace?
A fire test furnace is specifically designed for the characteristics of the fire test process: the furnace chamber size is suitable for accommodating the test crucible and ash dish; it has a good ventilation and fume extraction system to promptly remove fumes generated during the smelting process; and it has high temperature control accuracy to meet the stringent temperature profile requirements of the test process.
- How effective is the ventilation and fume extraction?
The fire test process generates harmful fumes containing lead and other pollutants. The furnace body is equipped with fume extraction ports at the top or rear, which can be connected to the user's exhaust system to promptly remove fumes, protecting the health of operators and meeting environmental protection requirements.
- How safe is it?
It features safety functions such as over-temperature alarm, thermocouple breakage protection, and overcurrent protection; some models also include a door-open power-off function. The furnace shell adopts a double-layer air-cooled structure, with a surface temperature ≤45℃, ensuring it remains cool to the touch.
- Can it be customized?
The furnace size (number of crucibles or specifications of ash trays) can be customized according to the batch size of the user's samples. Optional features include exhaust gas purification devices, computer communication interfaces, and multi-segment program control.
