Lab 27L Muffle Furnace Heat Treatment

The high-temperature box furnace integrates the control system and the furnace chamber into a whole, with a compact and beautiful structure. The furnace lining is made of vacuum-formed high-purity alumina poly-light material, which has low heat storage, good heat preservation and energy saving effect, and 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 the laboratories of universities, scientific research institutes, and industrial and mining enterprises as ideal equipment for sintering, melting, analyzing and researching metal, non-metal and other compound materials.

Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient alumina fiber ceramic insulation
High quality MoSi2 heating elements for fast and uniform heating.
Heavy duty double layer structure with cooling fan. Lower temperature outside case.
B type thermocouple installed for immediate use
PID automatic control via current  limiting phase angle fired the resistor.

1. The furnace body is a one-piece structure with a double-layer furnace shell, which can realize air circulation and heat insulation; the surface of high-quality carbon steel is used for rust removal and electrostatic spraying.
2. The furnace is made of light and high-purity alumina, sintered at high temperature without volatile matter.
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. When 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.
6. There are power indicator lights and heating indicator lights on the control panel, which can check the working status of the equipment at any time.
7. A circuit breaker is installed on the side panel of the equipment. When there is a short circuit or leakage, the circuit breaker will automatically protect it, which will neither cause safety hazards to the human body nor cause damage to the equipment.
