Automatic Fire Assay Furnace

  • Automatic Fire Assay Furnace
  • Automatic Fire Assay Furnace loading
  • Automatic Fire Assay Fusion Furnaces crucible load

TNK AF-05 Automatic Fire Assay Fusion Furnaces is designed and produced by ZJH minerals according to the international standard ISO10378-2005 "Copper, lead and zinc sulfide concentrate gold content determination fire assay method" . It is special for ore and metallurgical products to do fire assay. The equipment has a number of national patents, and the furnace modular combination can be independently disassembled and replaced for easy maintenance. The equipment intake and exhaust air can be automatically controlled without opening the furnace door, reducing the harm of lead oxide to the human body. Patented supporting tools make the work more accurate and convenient.

In the process of constant temperature, the range of furnace temperature fluctuation is small, and the temperature uniformity in the furnace is good. High degree of automation control, human-machine dialogue interface friendly, simple and clear operation. Professional for fusion work, melting effect is obviously better than ordinary high temperature Muffle furnace. A large number of project case show that the product has fully met the design requirements, the performance is good, the reproducibility is good, the experimental error is small.

Features

  • High temperature is heated by electrically power up to 1300 °C
  • Professional fire assay fusion process control software, all english touch screen operation interface, friendly,simple and practical operation. The experimental steps can be programmed variably, which is convenient to realize the fire assay experiment of various samples
  • The equipment intake and exhaust air can be automatically controlled without opening the furnace door, reducing the harm of lead oxide to the human body. It is more friendly for the operator.
  • Chimney opening and closing automatic control, adjustable opening, intake gas controllable, conducive to the experimental personnel to provide appropriate experimental environment according to the characteristics of different samples
  • Furnace chamber modular combination design, can be independently disassembled and replaced for easy maintenance. The furnace chamber is unique in design and equipped with a gas deflector with patented technology to guide the hot air down to form an air circulation channel in the furnace. The temperature gradient in the furnace can be effectively reduced by the heat conduction of the soaking plate in the furnace, and the ideal fusion effect can be obtained
  • Could make an appointment to automatically start the heating program to realize the advance heating of the equipment and effectively improve the experimental efficiency.
  • The heating circuit has the function of electronic collecting current. With broken rod, current imbalance protection and alarm function, to ensure the safety of electricity. With over temperature, broken thermocouple protection and alarm function, can effectively avoid equipment excessive heating damage.
  • The patented kit makes sample retrieval and placement more accurate and convenient
