The high-temperature box-type furnace integrates the control system and the furnace chamber into one, with a compact and beautiful structure. Furnace lining is made of vacuum-formed high-purity alumina poly-light material, which has low heat storage, excellent heat preservation, and energy-saving effect, and greatly reduces the overall weight of the electric furnace. The furnace shell adopts a double-layer air-cooled structure to ensure that the surface temperature of the furnace shell is close to room temperature. The temperature control system adopts an industrial precision 0.2-level intelligent instrument, PID control, 51-segment programmable heating curve, and a high degree of automation. This series of electric furnaces are widely used in universities, research institutes, laboratories, and industrial and mining enterprises as ideal equipment for sintering, melting, analyzing, and researching metal, non-metal, and other compound materials.

• 1. The furnace body is a one-piece structure with a double-layer furnace shell, which can achieve air circulation and heat insulation; the surface of high-quality carbon steel is used for rust removal and electrostatic spraying, which meets international laboratory standards.

• 2. The furnace is made of light high-purity alumina, sintered at high temperature without volatile matter, safe and environmentally friendly, in line with international industry standards.

• 3. The heating elements adopt high-quality molybdenum-containing resistance wires, silicon carbide rods, silicon molybdenum rods, and other heating elements. The rods are reasonably distributed according to the size of the furnace and the furnace temperature is uniform.

• 4. After the instrument program setting is completed, just press the run button, the next heating and cooling work will be completed automatically, without manual waiting.

• 5. The machine will send out an alarm signal for over-temperature conditions during work, and automatically complete the protection action.
