Tubular furnace for 1700 ℃ Temperature

Product Description:

Tubular atmosphere furnace with high standard, high configuration, high requirements of R & D and innovative design, in strict accordance with energy saving and environmental protection of new materials, new technology R & D and manufacturing, energy saving more than 50% than ordinary old electric furnace, replace (old type high energy consumption, high pollution) electric furnace, integrated design, small space, especially save experimental space and energy.

Htt-1700g-60 tubular atmosphere furnace is mainly composed of light alumina fiber furnace, silicon molybdenum rod, transformer, furnace body, electrical control system, corundum tube, vacuum system, etc.

1. Light alumina zirconium fiber furnace: 1800 type high-quality vacuum adsorption molding high-purity alumina polycrystalline fiber material and anti infrared thermal radiation and other new materials are used. The furnace is of assembled structure, with good thermal insulation performance, durability and high tensile strength. The furnace inner surface is coated with high temperature heat insulation coating, which can effectively prevent ash from falling, high temperature resistance and good thermal insulation performance. The thermal insulation material is filled with 1400 type alumina brazing material. The silicon molybdenum rod is a heating element, and the silicon molybdenum rod is a U-shaped rod, which is vertically suspended on both sides of the furnace tube from the upper part of the furnace body, with strong thermal radiation, convenient maintenance and easy replacement.

2. Furnace shell: the furnace shell adopts an integrated design of double-layer structure. The surface of the furnace shell is treated with antirust and high-temperature baking paint. The two-color matching design of the exterior color is beautiful and generous. The inner layer of the furnace shell is made of thickened cold-rolled plate by special process folding and welding. The reinforcement around the shell is evenly distributed and strengthened. A ventilation device is installed between the two layers to ensure the temperature rise of the shell below 30 ℃.

3. Electrical control system: the temperature control system adopts the digital program temperature controller, 50 sections of temperature rise and fall program can be programmed step by step, heating, insulation, cooling program (realize automation), Artificial Intelligence PID adjustment algorithm, solid state relay control mode. Electrical components are high quality components. The control panel includes digital program temperature controller, heating indication, power switch and start stop button. The control system has alarm protection functions such as over temperature, temperature deviation, electric leakage and broken couple, which can automatically cut off the heating power supply.

4. Vacuum charging system: the furnace tube adopts high purity corundum tube as the working room, and the two ends of the corundum tube are pressed and sealed with stainless steel flange and double O-type fluororubber ring. The professional vacuum design and sealing technology ensure that the vacuum degree and sealing performance far exceed those of similar products. It is equipped with valve joints such as charging, venting and vacuum pumping, with good sealing performance, and a high pumping speed vacuum pump, which can quickly empty the furnace Air. After vacuumizing, protective atmosphere can be introduced into the furnace. The inlet flow rate and pressure can be controlled by the charging valve and flowmeter of the tubular atmosphere furnace, which can realize flowing atmosphere protection and sealing atmosphere protection. The gases that can be injected into the furnace include nitrogen, argon, oxygen and other common gases.

This series of products are specially developed for sintering, melting, analysis and production of ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractories, new materials development, special materials, building materials, metals, nonmetals and other chemical and physical materials in laboratories and industrial and mining enterprises of institutions of higher learning and scientific research institutes.
