Sealed Multi-purpose Furnace for the Preparation of Violet Tungsten Oxide

The preparation of high-quality violet tungsten oxide has attracted more and more attention. In addition to improving the preparation process, upgrading the preparation device can also improve the quality of violet tungsten oxide effectively. Sealed multi-purpose furnace is suitable for the production of high-quality violet tungsten oxide.

Sealed multi-purpose furnace is a new generation powder metallurgy equipment. It is suitable for melting compound of non-ferrous metal, which has high melting point, into oxides through calcination reduction. This kind of equipment is efficient, environmental-friendly and energy-saving. It is especially suitable for the production of high-quality violet tungsten oxide. In addition, the technology of double dynamic seal has been adopted in this kind of furnace.

Here are the characteristics of sealed multi-purpose furnace as following as:

1. A new type of dynamic sealing device is adopted and the service life of seal is more than 15000 hours.

2. Small air volume is adopted to prevent material loss caused by excessive pumping force, and the powder recovery rate is over 99.5%.

3. The operation cost is low and the performance is stable. The furnace can be filled with hydrogen to prepare violet tungsten oxide.

4. New transmission of slide rail is adopted, which is stable and reliable. The manual plate can prevent deformation of the furnace tube and extend its service life.

5. The improved cone-shaped discharge bin is adopted. And the mixing and cleaning device is mounted to keep material flow in order and avoid the agglomeration of material. Therefore, violet tungsten oxide prepared by this kind of equipment is of high quality. In addition, this kind of equipment has characteristics of low energy consumption, high thermal efficiency and good thermal insulation. The temperature rise of the furnace surface (except the two ends) is less than or equal to 35°C.

Violet tungsten oxide is an important raw material for the preparation of ultrafine tungsten powder. In order to prepare high-quality violet tungsten oxide, the selection of the furnace is extremely important. Only adopt the furnace with good mechanical properties, can ultrafine tungsten oxide be successfully prepared. Sealed multi-purpose furnace is an ideal equipment for the production of high-quality violet tungsten oxide.
