Dy main purpose is: (1) as an additive, a neodymium-iron-boron permanent magnets, adding about 2 to 3% of dysprosium in this magnet, the coercivity can be improved, the demand for the past little dysprosium, However, as the demand for NdFeB magnets increases, it becomes a necessary additive element, and the grade must be around 95 to 99.9%, and the demand is also rapidly increasing. (2) é• is used as a phosphor activator. Trivalent cerium is a promising active ion of a single luminescent center trichromatic luminescent material. It is mainly composed of two emission bands, one for yellow emission and the other for blue light. The emitted, erbium-doped luminescent material can be used as a trichromatic phosphor. (3) Preparation of dysprosium is necessary magnetostrictive metal bonding material Terfenol gold (of Terfenol) alloy, a number of precision moving mechanical motion can be achieved. (4) Base metal can be used as a magneto-optical storage material with high recording speed and reading sensitivity. (5) Preparation of the lamp for the dysprosium, used in the working substance is dysprosium iodide, dysprosium lamp, which lamp has high brightness, good color, high color temperature, small size, arc stability, etc., has been used in film, printing And other lighting sources. (6) Because the cerium element has a large neutron capture cross-sectional area, it is used in the atomic energy industry to determine the neutron energy spectrum or to make a neutron absorber. (7) Dy3Al5O12 can also be used as a magnetic working substance for magnetic refrigeration. With the development of science and technology, the application fields of é• will continue to expand and extend.
Electric grab Bridge Crane is mainly comprised of box-shaped bridge, grab crab (Grab Bucket), trolley travelling mechanism, cab and electric control system. The load handing device is the grab which is able to capture bulk materials.
The grab cab has switching mechanism and lifting mechanism. The grabs are separately hung over the switching mechanism and lifting mechanism with four steel wire ropes. The switching mechanism drives the grab to close to grab material. When the grab is closed, the lifting mechanism shall be started immediately to hoist the four evenly loaded steel wire ropes. Discharging only needs to start the switching mechanism, which opens the grab to pour materials.
Except the lifting mechanism, the Overhead Crane is basically the same as the bridge crane with hook.
