This box type muffle furnace highest working temperature is 1900 ºC, uses heating element 1800 high-quality silicon molybdenum rod, with a long working life and better furnace temperature uniformity. The double-layer air-cooled structure furnace shell can keep surface temperature always below 45 degrees Celsius. The furnace top is a reinforced composite structure, more durable for long-term usage. The box type ceramic fiber muffle furnace can be used for heat treatment, high-temperature sintering, metal annealing, and quality testing; It's widely used in laboratories and enterprises.
