Problems solved by technology

On the other hand, since the Pidgeon reduction tank works under high temperature and vacuum for a long time, the tank wall will gradually collapse due to high temperature creep, and then fail
At present, the average service life of the reduction tank is only 2-3 months

Embodiment Construction

[0016] The invention overcomes the disadvantages of long reduction period and short service life of the traditional Pidgeon method by providing a reduction tank intensifier device for the horizontal reduction tank. However, the present invention does not change the existing technological process and equipment of the Pidgeon method, nor does it increase the difficulty of loading and unloading materials.

[0017] Fig. 1 and Fig. 2 are respectively the transverse and longitudinal sectional views of the reduction tank strengthener (one of the embodiments). The reduction tank strengthener (100) is composed of three reinforcing plates that are radially formed at an angle of 120 degrees to each other and made of heat-resistant good conductor and heat-resistant material. One of the reinforcement plates (101) has an inclined surface, and some slag leakage through holes (103) are prefabricated on the other two reinforcement plates (102). During installation, the inclined-plane reinforc...

Abstract

The invention provides a reinforcement device arranged in reaction zone of horizontal Pidgeon Process reduction tank, which has well heat-conducting property to convey rapidly the heat from tank wall to low-temperature zone on tank center and benefit to heat all material quickly and evenly and cut reduction time with Pidgeon Process. It also balances the pressure on tank wall to prolong the creep resistance and service life of the tank. The double-bottom charge chute and a method to unload with predetermined slag through hole make it possible to load and unload material for reduction tank with reinforcement device.

Description

Technical field [0001] The present invention relates to the improvement of the traditional Pidgeon metal extraction process and equipment, more precisely, it shortens the metal reduction period and prolongs the reduction period by providing a method and device that can simultaneously enhance the heat transfer efficiency and creep resistance of the reduction tank The service life of the tank can be extended, thereby effectively improving the production efficiency and economic benefits of the Pidgeon process. [0002] The description of the present invention will take the refining of metal magnesium as an example. But it is also perfectly suitable for refining other volatile metals, such as calcium, strontium, zinc and so on. Background technique [0003] Invented in the 1940s, the Pidgeon metal extraction method (US Patent No. 2330143, Canadian Patent No. 415764, 415765 and 463416) is a method suitable for refining various volatile metals (such as magnesium, calcium, stronti...
