1500°C Tube Furnace
This tubular furnace can reach a maximum temperature of 1500°C. It features a double-shell structure and an air-cooling system. The furnace chamber is constructed of high-purity alumina fiber to minimize energy loss. The inner chamber surface is coated with a high-temperature alumina coating, which improves reflectivity and heating efficiency, extending the instrument's lifespan. It also includes overheat and burnout protection. The furnace offers advantages such as a balanced temperature field, low surface temperature, fast temperature ramp rates, and energy efficiency. It is ideal for universities, research institutes, and industrial and mining enterprises for sintering or annealing new material samples (under vacuum or inert gas protection).

A 20-tonne Acheson graphitization furnace can hold full power for 24 to 40 hours and then need five to seven days of cooling before anyone opens it. Peak temperature is the headline number, but cost per tonne is decided by three quieter things: the furnace type, the condition of the insulation, and the shape of the power profile. Two shops running the same 2800 °C schedule can differ by 30 percent in kilowatt-hours per tonne. The gap is usually not the transformer. It is compressed graphite fel...
