Fire Assay Fusion Furnaces
The Fire assay fusion chamber furnace is a kind of equipment used to melt crushed ore samples (containing precious metal) with mixed fluxes (powdered lead oxide) in a refractory clay crucible.
Qingdao Decent Group manufactures various types of laboratory fusion furnaces for fire assay. The industrial-sized, large-capacity furnace chamber can be loaded with multiple crucibles, which significantly improves the efficiency of laboratory smelting and testing of ore samples and reduces the frequency of manual operations.
Industrial-Sized Laboratory Fusion Furnaces for Precise Assaying
DECENT specializes in providing professional-grade industrial-sized laboratory fusion furnaces. These fire assay furnaces are designed for melting crushed or pulverized ore samples containing precious metals. With our various sizes available, our fusion furnaces can accommodate multiple crucibles, offering quick heating, easy operation, and maintenance.
At Qingdao Decent Group, we manufacture a wide range of laboratory fusion furnaces for fire assay. Our industrial-sized furnaces feature larger chambers capable of holding multiple crucibles. This enhances smelting and testing efficiency, minimizing the need for manual operations.
Our laboratory furnaces are equipped with an automatic temperature control system, ensuring uniformity and stability of high temperatures. This guarantees reliable fire assay processes and consistent analysis results.
