Abstract
The invention provides an energy-saving type smelting furnace sluice. The energy-saving type smelting furnace sluice comprises a sluice body (3) connected to a liquid outlet (2) of a smelting furnace (1), a spoiler (4) is arranged in the sluice body (3) fixedly, a flow channel (5) is arranged between the bottom end of the spoiler (4) and the sluice body (3), and a gas hood (6) is arranged on the sluice body (3) and is connected to a protection gas tank (7) preventing molten aluminum from being oxidized through a switching valve (8). According to the invention, by arranging the gas hood, the molten aluminum flowing out from the smelting furnace can be in an oxygen-free environment and can be prevented from making contact with air when discharged from the smelting furnace, and therefore oxidization can be reduced, and the quality of aluminum alloy can be improved.
Description
Technical field
The invention belongs to aluminium alloy production equipment field, especially relate to a kind of energy-saving launder of smelting furnace.
Background technology
At present, as wheel hub factory of automotive wheel manufacturing enterprise, be by aluminum alloy smelting furnace, aluminium ingot is melted, and then cast; In the production process of aluminium alloy, when aluminium liquid flows into chute from the leakage fluid dram of smelting furnace, because the pressure in smelting furnace is comparatively large, when opening smelting furnace leakage fluid dram, the aluminium vacuole produced because of high low head is more, and aluminium vacuole is easily oxidized to aluminium oxide.Therefore, the quality of aluminium alloy has been had a strong impact on.
Summary of the invention
In view of this, the present invention is intended to propose a kind of energy-saving launder of smelting furnace, to solve the easily oxidized problem of aluminium liquid, improves the quality of aluminum products.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of energy-saving launder of smelting furnace; comprise the cell body (3) be connected with the liquid outlet of smelting furnace (1) (2); spoiler (4) is set in described cell body (3); described spoiler (4) is installed in described cell body (3); runner (5) is provided with between described spoiler (4) bottom and described cell body (3); described cell body (3) top is provided with gas shield (6), and described gas shield (6) connects by switch valve (8) the protection gas tank (7) that avoids aluminium liquid oxidation.
Further, described protection gas tank (7) is nitrogen pot or argon tanks.
Further, temperature sensor is provided with in described protection gas tank (7).
Further, described temperature sensor connects a controller, and described controller controls the switch valve (8) of described protection gas tank (7).
Relative to prior art, energy-saving launder of smelting furnace of the present invention has following advantage:
The setting of energy-saving launder of smelting furnace gas shield of the present invention can make the aluminium liquid of outflow smelting furnace be in the environment of an anaerobic, when avoiding aluminium liquid to discharge from smelting furnace and the contact of air, reduces oxidation, improves the quality of aluminium alloy.
Accompanying drawing explanation
The accompanying drawing forming a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the energy-saving launder of smelting furnace described in the embodiment of the present invention.
Description of reference numerals:
1-smelting furnace, 2-liquid outlet, 3-cell body, 4-spoiler, 5-runner, 6-gas shield, 7-protects gas tank, 8-switch valve.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
A kind of energy-saving launder of smelting furnace; as shown in Figure 1; comprise the cell body 3 be connected with the liquid outlet 2 of smelting furnace 1; spoiler 4 is set in cell body 3; spoiler 4 is installed in cell body 3; be provided with runner 5 between spoiler 4 bottom and cell body 3, be provided with gas shield 6 above cell body 3, gas shield 6 connects the protection gas tank 7 avoiding aluminium liquid oxidation by switch valve 8.
Protection gas tank 7 is nitrogen pot or argon tanks.
Temperature sensor is provided with in protection gas tank 7.
Temperature sensor connects a controller, the switch valve 8 of controller Control protection gas tank 7.When temperature sensor detects higher than indoor temperature, controller gauge tap valve 8 is opened, gassy in gas shield 6, and protection aluminium liquid is not oxidized, and then improves the quality of aluminum products.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
