Abstract
The utility model relates to a protecting device which can effectively prevent the molten surfaces being oxidized when smelting the magnesium or the magnesium alloy, comprising a shell 3. The shell is provided with an air inlet pipe 1, an air outlet pipe 4 and a charging opening 2. The protecting device has the advantages of simple structure, convenient operation and low using cost, etc.
Description
One, technical field
The utility model relates to a kind of protector that can effectively prevent its molten surface oxidation when melting magnesium or magnesium alloy.
Two, background technology
Magnesium is a kind of very active metal, and very easily oxidation after the high temperature melting causes the wasting of resources and quality to reduce, and is used for casting or die casting then may cause scrap rate to increase as it.And for example its sfgd. is ineffective, also may cause the fierce oxidation of magnesium or magnesium alloy, burning, very causes accident from producing serious blast.Therefore, when magnesium or magnesium alloy smelting, all need adopt sfgd. to prevent the oxidation of magnesium or magnesium alloy.
At present, adopt usually on magnesium or magnesium alloy fused mass surface when melting magnesium or magnesium alloy, cover one deck sulfur dioxide gas, prevention magnesium or magnesium alloy contact with air, prevent the oxidation of magnesium or magnesium alloy.And in order to guarantee that the sulfur dioxide gas physical efficiency all can cover magnesium or Mg alloy surface in whole fusion process, be constantly to magnesium or magnesium alloy fused mass jet surface sulfur dioxide gas when melting.And can constantly provide the sulfur dioxide gas mode to be comparatively easily at present: the accumulating bottle of in special factory, sulfurous gas being made liquid and being packed into special; after being transported to the use place; in smelting pot, reach protection through special gas distribution station pipe-line transportation to magnesium alloy fused mass.Because the severe corrosive of sulfurous gas is all wanted control very strictly and higher to the equipment and the requirements for pipes that store, carry in storage, transportation and use.However, the equipment and the pipeline that store, carry also often damage, and cause the equipment cisco unity malfunction.Can cause also that if any leaking operator come to harm.
Three, summary of the invention
The purpose of this utility model designs a kind of simple in structure exactly; easy to use; in the time of effectively preventing melting; the protector of magnesium or magnesium alloy solution oxide; it includes housing; on this housing inlet pipe is arranged; escape pipe and charging bole; when using the utility model; housing is placed on the crucible edge of melting magnesium or magnesium alloy; again SULPHUR POWDER or the higher powder of sulphur content are put into housing from charging bole; utilize the heat at crucible edge (also can adopt in the housing to housing and interior sulphur heating thereof; outer alternate manner heating); inject the dried compressed air of certain flow from inlet mouth; air and sulphur are reacted at a certain temperature; generate sulfur dioxide gas; spray to magnesium or magnesium alloy solution surface in the crucible from the air outlet; make it to form magnesium oxide or magnesium sulfide protective layer, reach and prevent magnesium or the fierce oxidation of magnesium alloy solution in magnesium or magnesium alloy solution surface; the incendiary purpose.
The utility model makes the anti-oxidation technology of magnesium or magnesium alloy liquation simple greatly owing to adopt said structure, have simple in structure, easy to use, advantage such as use cost is low.
Four, description of drawings
Fig. 1 is the utility model example structure synoptic diagram;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is another example structure synoptic diagram of the utility model;
Fig. 4 is that the A-A of Fig. 3 is to sectional view;
Five, embodiment
Shown in Fig. 1,3, the utility model includes housing 3, and inlet pipe 1, escape pipe 4 and charging bole 2 are arranged on this housing; In order to make dry air enter in the housing and the reaction of SULPHUR POWDER thorough mixing, inlet pipe can stretch in the container, and the nozzle of its tail end is charging bole 2 correspondence positions in container, as shown in Figure 2; In like manner, for making the reaction of SULPHUR POWDER and dry air thorough mixing, charging bole 2 is at the port correspondence position of escape pipe, as shown in Figure 4; This volume of a container can be 0.0065-0.0095m
3, so that heating and reinforced, thorough mixing, react completely etc.
Claims (4)
1, a kind of magnesium or magnesium alloy smelting protector is characterized in that: it includes housing (3), and inlet pipe (1), escape pipe (4) and charging bole (2) are arranged on this housing.
2, magnesium as claimed in claim 1 or magnesium alloy smelting protector, it is characterized in that: inlet pipe stretches in the container, and the nozzle of its tail end is charging bole (2) correspondence position in container.
3, magnesium as claimed in claim 1 or magnesium alloy smelting protector is characterized in that: charging bole (2) is at the port correspondence position of escape pipe.
