Product description:
The high-temperature box-type atmosphere furnace is a high-temperature box-type atmosphere furnace independently developed by our company. The furnace uses molybdenum-containing resistance wire as the heating element, and the temperature can reach up to 1200°C. The furnace material is made of alumina polycrystalline fiber material, with double It has a layered shell structure and a 30-segment programmable temperature control system, thyristor control. The furnace material is made of alumina polycrystalline fiber. There is an air-cooling system between the double-layer furnace shells, which can quickly raise and lower the temperature. It can be pre-evacuated and passed through multiple furnaces. An inert gas protection, this furnace has the advantages of balanced temperature field, low surface temperature, fast temperature rise and fall rate, energy saving, etc. It is suitable for atmosphere protection sintering in universities, scientific research institutes, industrial and mining enterprises.
atmosphere furnace
Features:
1. The furnace is made of high-quality alumina polycrystalline fiber inorganic material, which has good thermal insulation performance, durability, high tensile strength, no debris, high purity, and the energy-saving effect is significantly better than other domestic fiber materials;
2. The entire furnace body adopts a double-layer inner tank structure with an air gap in the middle. Even if the temperature of the furnace reaches the highest level, the surface of the furnace body can still be touched safely without feeling hot.
3. The furnace is made of energy-saving materials, and the energy consumption of the whole machine is only 1/3 of the same traditional electric furnace, which is energy-saving and environmentally friendly.
4. The heating element uses molybdenum-containing resistance wire, which has a fast heating rate.
5. The temperature control system adopts touch screen operation, artificial intelligence adjustment, PID adjustment, and self-tuning functions. It can program 30-segment temperature rising and cooling programs, and the temperature rising and cooling data can be stored and output in real time.
6. It has over-temperature alarm and power-off protection function, and is equipped with a safety valve. When the air pressure in the furnace is too high, it will automatically deflate, making the operation safe and reliable.
7. Our company has the ability to develop, design, produce and process by itself. Our machines provide lifetime parts replacement and upgrade services.


Structure introduction
The high-temperature box-type atmosphere furnace adopts a split design. The furnace body is separated from the control system. The door opening method is the front door opening to the right. It is portable and easy to load and unload. All insulation materials and heating elements inside the furnace body are removed from the furnace. It is installed on the upper part of the body and equipped with a movable cover. The control system box is equipped with various control components, panel operation, and simple and beautiful structure. The entire equipment is mainly composed of a lightweight alumina fiber heating and insulation furnace, furnace body, electrical control system, vacuum system, etc.
1. Lightweight alumina fiber furnace: Made of high-quality vacuum adsorption molded high-purity alumina polycrystalline fiber material and anti-infrared heat radiation and other new materials, it is resistant to high temperatures and has good heat preservation performance. Thermal insulation material is filled with aluminum oxide brazing material. The heating element uses molybdenum-containing resistance wire, which has a fast heating rate.
2. Furnace shell: The furnace shell adopts a double-layer integrated structure design, and the surface of the furnace shell is anti-rust and high-temperature sprayed with plastic.
The exterior color is technological gray, which is beautiful and elegant. The inner tank is made of thickened cold-rolled plates welded by a special process. The inner tank is evenly reinforced with strong reinforcements around it. A ventilation device is installed between the two layers to ensure that the temperature of the outer shell is not hot. Prevent high temperature burns.
3. Electrical control system: The temperature control system adopts (Xiamen Yudian) artificial intelligence temperature controller, 30-segment heating and cooling program, artificial intelligence PID adjustment algorithm, and thyristor control method. Electrical components are all made of (Chint Electric) components. Touch screen operation, heating and cooling data can be stored in real time, data can be output, and the control system has alarm protection functions such as over-temperature and couple failure.
4. Vacuum system (optional): Professional vacuum design and sealing technology ensures that the vacuum degree and sealing performance are far superior to similar products. It is equipped with valve joints for air intake, air release, and vacuum evacuation, and has safety pressure relief and automatic release. Qi function, safe and reliable. An optional special high-speed vacuum pump can quickly evacuate the air in the furnace, and the vacuum reaches the best state in a short time. After the vacuuming is completed, the protective atmosphere can be introduced into the furnace. The inlet flow rate and pressure can be controlled through the inflation valve and flow meter provided by the box atmosphere furnace, so that flowing atmosphere protection and sealed protective atmosphere protection can be achieved. The heated sample will not be oxidized.
