Laboratory intelligent constant temperature muffle furnaceBox type electric furnace, also known as resistance furnace, can be used for element analysis and determination in laboratories, industrial and mining enterprises, and scientific research units, as well as for general small steel parts quenching, annealing, tempering and other heat treatment heating. It can also be used for high-temperature heating such as sintering, dissolution, and analysis of metals and ceramics.

Box type electric furnaces, like other types of electric furnaces, have similar main functions, but they also have their own characteristics:

1. The furnace door of the box furnace is fixed to the electric furnace panel through multi-stage hinges. The furnace door is closed by using the self weight of the furnace door handle and the lever principle to tightly close the furnace door and mouth. When opening, simply lift the handle lock upwards, pull the rubber hook outwards, and place the furnace door on the left side. In addition, there is a safety switch at the lower end of the furnace mouth that is interlocked with the furnace door. When the furnace door is opened, the power supply of the electric furnace is automatically cut off to ensure safe operation;

2. The shape of the box furnace is rectangular, and the furnace shell is made of angle steel and high-quality steel plate folded and welded together;

3. The box furnace workshop is a furnace made of refractory materials, in which heating elements are placed, and insulation materials are used to build insulation between the high-temperature muffle furnace and the furnace shell

Laboratory intelligent constant temperature muffle furnaceProduct Usage:The muffle furnace is suitable for powder roasting, ceramic sintering, high-temperature experiments, chemical analysis, material processing, ceramics, metallurgy, electronics, glass, plastics, steel, precious metals, gemstones, chemical industry, machinery, refractory materials, new material development, special materials, and building materials quality testing in universities, research institutes, and industrial and mining enterprises. Special specification products can be designed and manufactured according to user needs.

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.

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.
