Embodiment Construction

[0029] In order to better understand the structure and features of the present invention, the present invention will be described in detail below in combination with preferred embodiments and accompanying drawings. In order to make the structure of the present invention clearer, the actual scale relationship of the drawings may be changed during the drawing process, which should not be construed as a limitation to the patent application.

[0030] like figure 1 As shown, it is a structural schematic diagram of a metal vacuum smelting reduction device capable of semi-continuous production in the present invention, including a reduction furnace 1, a reduction tank 4, a liquid crystallizer 8 and a liquid tundish 20, wherein:

[0031] The reduction furnace 1 adopts regenerative combustion technology, and is equipped with a furnace body 3 and a burner 2, both of which are prior art and will not be described in detail.

[0032] The reduction tank 4 is vertically arranged in the furn...

Abstract

The invention relates to a liquid crystallizer, which comprises a crystallizer shell body which is provided with containing space. The containing space communicates with a reduction pot through a flow guide device; a heating control device of the crystallizer for controlling the temperature of the containing space and a vacuum extractor of the crystallizer for controlling the vacuum degree of thecontaining space are arranged on the liquid crystallizer; an intermediate pipeline is also arranged on the crystallizer shell body and used for communicating with a liquid pouring box. By using the liquid crystallizer, the semi-continuous production for metal vacuum smelting can be realized, the productivity effect is increased, and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to a metal vacuum smelting reduction tank, in particular to a vacuum smelting reduction tank for smelting metal magnesium or calcium. Background technique [0002] Some alkali metals and alkaline earth metals with high vapor pressure, such as chromium, chromium, magnesium, calcium, etc., can be prepared by metallothermic reduction of silicon, aluminum or their alloys under vacuum conditions. Among the metallothermal reduction preparation methods of magnesium, the silicothermal or aluminothermic metalthermal reduction principles are most widely used, but the reducing agent is mostly used in the form of ferrosilicon alloy, and the raw material to be reduced is mostly calcined dolomite. A wrought product of a mixture of magnesite and limestone can also be used. The use of ferrosilicon reducing agent, known as silicothermal magnesium smelting, is the most widely used. [0003] According to the different heating methods, the current ...
