Abstract
The utility model relates to a device which is used for magnesium or magnesium alloy smelting, in particular to a magnesium or magnesium alloy smelting gas protecting device. The magnesium or magnesium alloy smelting gas protecting device solves the problem of the gas supply protection in the prior magnesium or magnesium alloy smelting technology, and comprises a cabinet; the cabinet is provided with a mixed gas tank; the mixed gas tank is connected with three gas inlet pipes, and a mixed gas supply pipe; each gas inlet pipe is provided with a flow meter and a pressure gauge; the mixed gas supply pipe is provided with a pressure gauge and a pressure regulating valve; the flow meters are arranged on a flow meter observation window on the outer surface of the cabinet; and the pressure gauges and the pressure regulating valve are arranged on the outer surface of the cabinet. The magnesium or magnesium alloy smelting gas protecting device can precisely set the proportion of the mixed gas, can regulate the flow of the output gas, and can be applied to the gas protection of all steps in metal magnesium or magnesium alloy smelting, such as smelting, heat preservation, casting and the like.
Description
Technical field
The utility model relates to the device of a kind of magnesium or magnesium alloy smelting use, is specially a kind of magnesium or magnesium alloy smelting gas shield device.
Background technology
The chemical property of magnesium or magnesium alloy is more active, and when beginning to melt, oxidation and burning need take sfgd. to prevent the molten metal surface oxidation easily.The fused magnesium alloy very easily generates hydrogen with water generation vigorous reaction, and might cause blast.Therefore it is very necessary magnesium alloy fused mass being adopted flux or protective atmosphere starvation or aqueous vapor.
At present, people extensively adopt SF in magnesium alloy smelting and production process
6Protective atmosphere.SF
6Protective atmosphere is a kind of very effective protective atmosphere, can significantly reduce melting loss, is widely used in ingot casting production industry and die casting industry.SF in actual production
6Normal and other gases mix and are passed into smelting furnace, and hybrid mode commonly used has air/SF
6, SF
6/ N
2, air/CO
2/ SF
6, send into smelting furnace after these gases accurately need being mixed by a certain percentage.Test shows, 0.01% SF
6Concentration can effectively be protected magnesium liquid, but the actual concentration that adopts wants big, general SF
6Concentration should not surpass 1%.SF in the protective atmosphere
6Concentration do not allow and surpass 2vol.%, otherwise can cause the crucible loss.Particularly at high temperature, SF
6When concentration surpasses a certain specific volume fraction, in the crucible vigorous reaction even blast may take place, therefore must be to SF in the mixed gas
6Concentration is carried out strictness control.In addition, crucible with cover can not adopt pure SF
6Atmosphere is protected.So the Design of device of the optimization of shielding gas supply and operation are the key equipments of realizing protection gas effect.
Summary of the invention
The utility model provides a kind of magnesium or magnesium alloy smelting gas shield device for the problem that solves the protection gas supply that exists in existing magnesium or the magnesium alloy smelting technology.
The utility model is realized by following technical scheme; a kind of magnesium or magnesium alloy smelting gas shield device; comprise cabinet; be provided with the mixing gas tank in the cabinet, mix on the gas tank being connected with three inlet pipe, one is sent mixture pipe; be respectively equipped with under meter and tensimeter on the inlet pipe; send mixture pipe to be provided with tensimeter and relief valve, under meter all is positioned at the under meter viewing window of cabinet outside surface, and tensimeter and relief valve also are positioned at the cabinet outside surface.
It is sulfur hexafluoride, carbonic acid gas, exsiccant air that three inlet pipe of mixing gas tank of the present utility model are carried composition respectively; by high precision control valve, under meter; can accurately set ratio of gas mixture; can regulate the output gas flow amount; can be applied to each link that MAGNESIUM METAL or magnesium alloy are smelted, the gas shield of links such as for example melting, insulation, casting.
