exterior design：The electric furnace adopts a humanized design, which is beautiful and easy to operate. The outer paint layer uses spray coating and high-temperature baking technology. Has high temperature resistance, oxidation resistance, and acid alkali resistance. Choose a color tone that is resistant to aging and will not fade in appearance due to prolonged use.Changchun high-temperature LCD digital display box type resistance furnace

Shell design：The electric furnace shell adopts a double-layer forced air cooling structure, which makes the external temperature of the furnace shell close to room temperature when the electric furnace works at high temperatures, avoiding accidental injuries.

Temperature control method：useYudian*The temperature controller is equipped with a 30-50 segment programmable PID self-tuning, automatic heating and cooling, and does not require on duty operation. RS-485 communication interface can also be optionally selected (connected to a regular computer to start, stop, pause heating, set heating curve, store heating curve, record historical curve, etc.)

temperature controlSystem:The electric furnace adopts integrated circuits, module control, and dual circuit protection (such as temperature deviation protection, ultra-high temperature protection, circuit breaker protection, overcurrent protection, overpressure protection, etc.) to ensure stable and reliable operation of the electric furnace.

heating rate：The heating rate is 30 ℃/minute, with a recommended rate of 20 ℃/minute.

Furnace material：Using lightweight alumina ceramic fibers, it has excellent insulation effect, light weight, high temperature resistance, resistance to rapid cooling and heating, no cracks, no crystallization, no slag falling, and no need to worry about contaminating the fired products. The energy-saving effect is 60% -80% of that of old-fashioned electric furnaces.

Furnace design：The furnace adopts a stepped assembly structure that integrates the laws of mechanics, effectively ensuring uniform force distribution during the heating process, preventing the loss of heat energy, and extending the service life of the furnace.

Warranty period：The electric stove comes with a 12-month free warranty. If the heating element and cooling fan are naturally damaged within 3 months, they will be replaced free of charge.

accessory：Standard accessories: 1 crucible clamp, 1 pair of high-temperature gloves. One copy of the user manual. Optional accessories:liquid crystalTouch screen control, configuration of air intake and exhaust chimney, paperless recorder, remote communication control system.

MaFu furnaces are divided into domestic MaFu furnaces and imported MaFu furnaces according to nationality. Divided by heating elements, there are electric furnace wire muffle furnace, silicon carbon rod muffle furnace, and silicon molybdenum rod muffle furnace; According to the rated temperature, it is generally divided into: 900 degree series muffle furnace, 1000 degree muffle furnace, 1200 degree muffle furnace, 1300 degree muffle furnace, 1600 degree muffle furnace, and 1700 degree muffle furnace. According to the controller, there are several types: pointer table, ordinary digital display table, PID regulation control table, program control table; There are two types of insulation materials: ordinary refractory bricks and ceramic fibers. So users must clearly state in the contract when purchasing products to avoid suppliers playing tricks.

The muffle furnace system operates in a periodic manner and is used for element analysis and determination in laboratories, industrial and mining enterprises, and scientific research institutions. It is also used for heating small steel parts during quenching, annealing, tempering, and other heat treatments. The high-temperature muffle furnace can also be used for high-temperature heating such as sintering, dissolution, and analysis of metals and ceramics

Precautions for using muffle furnace:

1. When the muffle furnace is used twice or after a long period of disuse, it must be dried. The baking time should be four hours at room temperature of 200 ℃. 200 ℃ to 600 ℃ for four hours. When in use, the furnace temperature should not exceed the rated temperature to avoid burning out the electric heating elements. It is prohibited to pour various liquids and easily soluble metals into the furnace. The muffle furnace operates at temperatures below 50 ℃, during which the furnace wire has a longer lifespan.

2. The muffle furnace and controller must be operated in a location with a relative humidity not exceeding 85%, free from conductive dust, explosive gases, or corrosive gases. When metal materials containing oil or grease need to be heated, a large amount of volatile gases will affect and corrode the surface of the electric heating element, causing it to be destroyed and shorten its lifespan. Therefore, timely prevention and proper sealing of containers or appropriate openings should be taken during heating to eliminate the problem.

3. The muffle furnace controller should be limited to use within the ambient temperature range of 0-40 ℃.

4. According to technical requirements, regularly check whether the wiring of the electric furnace and controller is in good condition, whether there is any jamming or retention phenomenon when the pointer of the indicator moves, and use a potential difference meter to calibrate the instrument for errors caused by fatigue and balance failure of magnetic steel, demagnetization, wire expansion, and spring fragments.

5. Do not suddenly pull out the thermocouple at high temperatures to prevent the jacket from exploding.

6. Regularly keep the furnace clean and promptly remove oxides and other substances inside the furnace.
