Embodiment Construction

[0019] This embodiment takes the production of magnesium metal as an example for illustration. As shown in Figure 1, the upper and lower parts of the reduction tank 3 vertically installed in the heating furnace protrude from the furnace roof 4 and the furnace bottom 6 of the heating furnace respectively, and the middle part of the reduction tank is heated in the heating furnace. A preheating storage bin 2 is installed at the upper end of the reduction tank 3, and the outlet of the preheating storage bin is sealed and fixedly connected with the upper end of the reduction tank 3, and the gap between the preheating storage bin 2 and the furnace roof 4 is A metal magnesium crystallizer 17 is fixedly installed on the reduction tank, and a connection port 18 connected with vacuum equipment is fixed on the metal magnesium crystallizer 17 . The outside of the protruding part of the lower end of the reduction tank 3 is fixedly equipped with a support frame 16, and the reduction tank is...

Abstract

The invention relates to a metal production method and the production facility thereof, particularly a process for semi-continuous production of light metals and the production facility thereof. The whole process is performed in a reduction pot, raw materials are fed into the reduction pot by using a sealable preheating storage chamber fixed on the top of the vertical-type reduction pot, and the content of reaction residues inside the reduction pot is above zero when the reaction residues are discharged. The reduction pot is vertically arranged inside a heating furnace in a way that the upper and bottom ends thereof extend out of the roof and hearth of the heating furnace, and is connected with the hearth of the heating furnace via a supporter. The upper end of a discharge tube with a cooling jacket is hermetically connected with the bottom end of the reduction pot, and the lower end of the discharge tube is provided with an openable / closable discharging device that is hermetically sealed with the lower end of the discharge tube when closed. The inventive process and facility can efficiently reduce the time of the whole reduction procedure, increase the heat efficiency of the production process, and increase the production capacity of reduction pot by about one time without changing other production conditions, resulting in significant economic benefits.

Description

technical field [0001] The invention relates to a metal production method and its production equipment, in particular to a semi-continuous production of light metal production technology and its production equipment. Background technique [0002] At present, the smelting of light metals by Pidgeon method has become a classic method. Taking metal magnesium as an example, more than 60% of metal magnesium is smelted by Pidgeon method. This method has some problems that cannot be ignored in the long-term production process. For example, the invention patent application titled "Pidgeon Metal Refining Process and Equipment" published by the China Intellectual Property Office on December 7, 2005, mentioned some problems in the current Pidgeon smelting process in the invention patent application, A method for simultaneously enhancing the heat transfer efficiency and creep resistance of a Pidgeon reduction tank is disclosed. The invention discloses a method for realizing the automa...
