Taiyuan program-controlled box type resistance furnaceDaily maintenance precautions
1. When the muffle furnace is used twice or after a long period of disuse, it must be dried. The baking time should be between 200 ℃ and 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 ℃, which results in a longer lifespan of the furnace wire.
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. The thermocouples connected to the controller may cause interference to the controller, resulting in phenomena such as jumping of display values and increased measurement errors. The higher the furnace temperature, the more obvious this phenomenon becomes. Therefore, it is necessary to ground the metal protective tube (housing) of the thermocouple well, and if necessary, use a three wire output thermocouple. In short, all effective measures should be taken to reduce interference.
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.
7. During use, when melting samples or burning precipitates with alkaline substances in the furnace, the operating conditions should be strictly controlled. A layer of refractory plate should be pre laid at the bottom of the furnace to prevent corrosion of the furnace.
Taiyuan program-controlled box type resistance furnaceProduct Usage:The muffle furnace is suitable for powder roasting, ceramic sintering, high-temperature experiments, chemical analysis, material processing in universities, research institutes, and industrial and mining enterprisesceramics、metallurgy、electron、glassPlastic, steel, precious metals, gemstoneschemical industry、machinery、refractory material、New material development、special materials、building materialsUsed for quality inspection. 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.
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.
