DEVICE FOR PRODUCTION OF DISTILLED CALCIUM INGOTS Russian patent published in 2008 - IPC C22B26/20 C22B9/04 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy, particularly to device for production of distilled calcium ingots. The technical result of the invention is means for production of distilled calcium ingots of 65-75 kg of weight out of bulk metal without changing dimensions of existing thermal equipment and of distillation retorts. The device consists of an electric furnace and a retort with a refrigerator where are successively along the height installed a charge cartridge, a filter of "Рашига" rings and a receiving cylinder-capacitor. Additionally a cylinder insertion is coaxially installed in the retort; the said insertion is designed to move inside the cylinder-capacitor and the charge cartridge, and at its extreme upper position it is located in the upper portion of the retort, while at its extreme lower position it is located at the level providing the insertion placement inside the charge cartridge; thus an overlapped from above ring gap is created between their walls, while below the cylinder insertion there is created a reservoir for cube remains. At that the filter out of rings "Рашига" is installed in the upper portion of the cylinder insertion.

EFFECT: facilitating means for production of distilled calcium ingots of 65-75 kg of weight out of bulk metal without changing dimensions of existing thermal equipment and of distillation retorts.
