Description
Technical field
The utility model relates to a kind of pouring device, particularly a kind of device of the reduction potting head that is used to cast.
Background technology
In the magnesium metal production process, one of them important operation is a reduction process, in the reaction of reduction process, utilizes Si that Mg is cemented out from MgO.This reduction process is carried out in the reduction jar.Fig. 1 is the schematic diagram of the reduction jar of prior art.As shown in Figure 1, an end that is provided with the reduction jar of end socket 1 seals, and 3 all are placed in the reduction furnace from the blind end to the connecting portion, and the temperature in the reduction furnace is about 1200 ℃, and in reduction process, cold junction 4 is sealed, and will reduce jar and vacuumize.The tank body 2 and the end socket 1 of reduction jar are made by heat-resisting steel material, but their preparation method's difference, and tank body 2 is with centrifugally cast method preparation, and end socket 1 utilizes the method for gravitational casting to prepare, and then the two is welded together.
The method of centrifugal casting is that a molten steel of fusing waters a mould the inside of rotation at a high speed, and molten steel clings on the mould, along with the mold cools down moulding owing to action of centrifugal force.Because the speed of mould rotation is very high, so the suffered centrifugal force of molten steel is very big, so organizing of tank body 2 is very fine and close.And end socket 1 is owing to utilize gravitational casting, and volume is less, so its final tissue looseness, even has defectives such as shrinkage porosite, shrinkage cavity.According to calculating, in forming process, the suffered pressure of tank body 1 material that utilizes centrifugal casting is about 60 times of end socket 2 material pressures that utilize gravitational casting, so dense structure's property of tank body material is played the tissue far above seal head material.
In the magnesium metal reduction process, owing to contain iron and nickel reactant in pernicious gas such as sulfur dioxide and the reduction tank material in the employed fuel, generate compositions such as iron sulfide and nickel sulfide, and this reaction occurs in the position of crystal boundary at first, and the fusing point of product is lower than 1000 ℃ (about 1200 ℃ of temperature in the reduction furnace), therefore causes and organizes corrosion spalling.Compare with tank body 2, organizing of end socket 1 is very loose, so corrosion rate will be far above tank body 2.Therefore in use, under the also intact situation of tank body, end socket at first corrodes and causes gas leakage, finally causes whole reduction jar to be scrapped.And the cost of tank body causes great waste far above the cost of end socket.
But also there is not the relevant report for preparing the device of reduction potting head with centrifugal casting process at present.
Summary of the invention
At above-mentioned existing in prior technology problem and shortage, the utility model has designed a kind of device that utilizes centrifugal casting process preparation reduction potting head, utilize the method preparation reduction potting head of centrifugal casting, improve dense structure's property of reduction potting head, improve its corrosion resistance, increased the service life of whole reduction jar.
The utility model provides a kind of device of spun casting reduction potting head.This device comprises: axle, bed die and mold, and wherein this mold is placed on this bed die, and this mold and this bed die link together removably, and this bed die and this axle are fixed together.
According to described device, this bed die is connected by key with this axle and is combined together.
According to described device, between this bed die and this axle, can be provided with the mould seat, this mould seat and this bed die link together removably, and this mould seat is connected by key with this axle and is combined together.
According to described device, this mold, this bed die and this mould seat are linked together by nut and pressing plate.
According to described device, this is inserted in the bracing frame that is provided with the hole, and is combined together by bearing and this bracing frame.
According to described device, between this axle and this bracing frame, can be provided with axle sleeve, this axle sleeve is combined together by bearing and this axle.
According to described device, in this bottom belt pulley is installed, this belt pulley connects by key and this axle is combined together.
The device of casting reduction potting head of the present utility model has following advantage:
(1) improves dense structure's property of reduction potting head greatly.
(2) casting process is simple.
(3) mould utilizes pressing plate to connect convenient disassembly up and down.
(4) improve the corrosion resistance of reduction potting head greatly, improve the service life of reduction jar.
Description of drawings
Fig. 1 is a reduction jar structure schematic diagram.
Fig. 2 is the installation diagram according to casting reduction potting head unit of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 2, mold 5 is placed on the bed die 11, and they are assembled together by pressing plate 3 and bolt 4, but the utility model is not limited to pressing plate 3 and bolt 4, also can use other dismountable mode that mold 5 and bed die 11 are assembled together.Be provided with the casting gate 112 that is used to cast on the top of mold 5.In addition, mold 5 and bed die 11 also are respectively equipped with locating hole projection and locating hole 111, are used to guarantee the accurate cooperation of mold and bed die.
Bed die 11 can directly cooperate (for example, connecting by key) with axle 9 together, rotates with mold 5 so that axle 9 drives bed die 11.But for easy for installation, and prevent to change when bed die is damaged conveniently, as shown in Figure 2, between bed die 11 and axle 9, can be provided with mould seat 2.Can mold 5, bed die 11 and mould seat 2 be assembled together by pressing plate 3 and bolt 4.Mould seat 2, rotates so that axle 9 drives mould seat 2, bed die 11 and mold 5 together with axle 9 affixed (for example, cooperating by the key connection) together.
In order to make axle 9 stable rotations, axle 9 is put in the bracing frame 1 that is provided with the hole, be combined together by rolling bearing 10 between bracing frame 1 and the axle 9.Alternatively, except rolling bearing 10, can also be provided with pressure bearing 6 between bracing frame 1 and the axle 9, be used to bear appendicular weight on axle 9 and the axle 9.
In addition, preferably, between bracing frame 1 and axle 9, can also be provided with axle sleeve 7.In this case, axle sleeve 7 is made from a variety of materials with bracing frame 1, and the material of making axle sleeve 7 is better than the performance of bracing frame 1.Therefore, when not having axle sleeve 7 than bracing frame 1 and axle between 9, whole bracing frame 1 all needs situation about making with the performance better material, has saved manufacturing cost.The upper and lower part of axle sleeve 7 can seal with gland 13 and bolt 12.
In addition, in the bottom of axle 9 belt pulley 8 is installed, the device that belt pulley 8 can more external motors and so on comes driving shaft 9 rotations, driving bed die 11 and mold 5 rotates, thereby carries out spun casting.
It is as follows to use the device of spun casting of the present utility model reduction potting head to prepare the process of end socket: starter motor drive unit at first, and making axle 9 rotations and rotating speed is 100 rev/mins to 600 rev/mins, thereby drives mold 5 and bed die 11 rotates together; Then the casting gate 112 of molten metal liquid from mold 5 poured into the mould, when molten metal pours into 2/3rds places of die casting mouth, stop casting; After stopping casting, axle 9 continues rotation 5 to 15 minutes, stops operating then; Open bolt 4 and pressing plate 3, take out the reduction potting head of moulding; The potting head that will reduce is placed into and carries out nature in the holding furnace and cool off with stove; During cool to room temperature, the potting head that will reduce takes out, and chamfering welds together with the reduction tank then.
Use the reduction potting head of the device preparation of spun casting reduction potting head of the present utility model, the service life of organize densification more, intensity is high, corrosion resistance is strong, having improved the reduction jar.
