The purpose of the sintered tube furnace turned out to be so important, I blamed it for underestimating it in the first place
Tube furnace may not be unfamiliar to many people in the industry, but they may not understand its type and use. Compared with traditional large kilns, this kind of kiln looks small, but the structure is more complex, which is inseparable from its important function.
As a large-scale equipment, the traditional rotary kiln has been widely used in the cement, lime and steel industries, but the large-scale equipment for the traditional industry and garbage incineration treatment, etc., pay attention to the output and incineration temperature, as long as the purpose of calcination can be achieved, but it lacks many accurate functions, and does not have a good sealing and reduction reaction and other kiln environment.
With the development of science and technology, the performance requirements for new materials are getting higher and higher, which requires a more accurate and miniaturized kiln for experiments, pilot reactions and small batch production, in order to provide parameter support for subsequent technologies. Tube furnaces, then, have many advantages. For example:
1. The maximum temperature is 1100-1800, and the heating zone is 300mm.
2. The furnace body adopts a double-layer furnace shell structure, and a fan is installed between the double-layer furnace shells, which can quickly raise and lower the temperature, and the surface temperature of the furnace shell is low.
3. The furnace tube is made of high-purity quartz tube or corundum tube, and the two ends are sealed with SUS304 high-vacuum flange.
4. The furnace material is made of high-quality imported alumina polycrystalline fiber vacuum adsorption, which has significantly improved energy saving compared with the traditional hard furnace material electric furnace, and has strong resistance to sudden cooling and sudden heating, the 1100 electric furnace furnace is composed of two parts, of which the upper part of the furnace can be turned backward as a whole 110, and the furnace of more than 1100 electric furnace is integrated, which is convenient for taking and placing experimental materials and replacing the furnace tube. The heating element is made of Swedish Contelle resistance wire, silicon carbon rod and silicon molybdenum rod.
5. The temperature control system of the electric furnace adopts artificial intelligence adjustment technology, the instrument control accuracy is 1, it has the ability of PID adjustment, fuzzy control, self-tuning and can compile various heating programs, has the function of ultra-high temperature alarm, has the function of thermocouple damage and power-off, and has the function of built-in parameter password control.
6. The heating rate is 30 min (the recommended heating speed is 10 min), 30 automatic heating programs can be written, thyristor control, equipped with digital LED voltmeter and ammeter.
Because many scientific research units, universities, industrial enterprises, etc. also use it to carry out experiments and tests on a variety of materials, therefore, the small one is also called the experimental rotary kiln. The equipment is equipped with a vacuum pump, a gas mixing device. The temperature control system adopts PID mode adjustment, high temperature accuracy, excellent gas flow accuracy, easy operation, very good thermal insulation effect and temperature uniformity. It is mainly used in rare earth preparation, electronic lighting, crystal annealing, bioceramics, electronic ceramics, special alloys, magnetic materials, precision casting, metal heat treatment and other industrial vacuum sintering, protective atmosphere sintering, CVD experiments, vacuum deposition, material composition determination and other occasions.
