Description
Technical field
The utility model relates to a kind of device, in particular to a kind of novel hot-die Surface of Centrifugal Cast Ductile Pipe liquid iron balling device.
Background technique
Currently, nodularization mode is blowing process in hot-die Ductile Pipe Production, Fig. 1 is seen, but due to the cooling speed of hot-die ductile iron pipe
Degree is slow, and nodularization and casting interval time are long, cause hot-die ductile iron pipe metallographic decaying spheroidisation defect often to occur, and blowing process magnesium
Grain usage amount >=2.3kg/t, cost is also higher, needs to design a kind of easy to operate, saving cost, and improve hot-die centrifugation magnesium iron
The liquid iron balling mode of pipe metallographic spheroidizing quality, therefore, a kind of novel hot-die Surface of Centrifugal Cast Ductile Pipe liquid iron balling device will possess
Good market prospects.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of existing technologies, and provides a kind of novel hot-die centrifugal globe
Iron pipe liquid iron balling device, it is easy to use, save a large amount of cost.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:
The utility model provides a kind of novel hot-die Surface of Centrifugal Cast Ductile Pipe liquid iron balling device, including pipe die, in the pipe die
Portion is provided with chute, and the chute surface flow has flowing molten iron, and the pipe die bottom is provided with pipe die support roller, the chute one
Side is provided with mould powder cloth packet, and magnesium grain and mould powder mixture, mould powder cloth packet side are housed inside the mould powder cloth packet
It is provided with fan-shaped packet, the fan-shaped packet is internally provided with fan-shaped iron clad water, and the fan-shaped packet bottom is provided with pouring truck, described to pour
Note vehicle side is provided with spray gun.
As a kind of optimal technical scheme of the utility model, the pipe die is identical as the fan-shaped packet direction of rotation.
As a kind of optimal technical scheme of the utility model, the pipe die support roller passes through screw and nut phase with the pipe die
Connection.
The utility model beneficial effect achieved is: the utility model has the advantages of simple structure, cheap, and practicability
By force, 1. nodularization costs reduce, and the consumption of magnesium grain drops to 1.5-1.8kg/t by 2.3kg/t；2. due to casting and nodularization it is basic simultaneously into
It is capable, it changes traditional nodularization mode nodularization and the drawbacks of bringing is grown at duration of pouring interval, greatly improve metallographic spheroidizing quality,
3. it is easy to operate, the working efficiency of device is improved, a large amount of cost has been saved, it is easy to use, there is good economic effect
Benefit and social benefit are suitble to promote the use of.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the subjective structural schematic diagram of the utility model；
In figure: 1, chute；2, molten iron is flowed；3, pipe die；4, pipe die support roller；5, magnesium grain and mould powder mixture；6, mould powder cloth
Material packet；7, fan-shaped packet；8, fan-shaped iron clad water；9, pouring truck；10, spray gun.
Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment: as shown in Figure 1, the utility model provides a kind of novel hot-die Surface of Centrifugal Cast Ductile Pipe liquid iron balling device, packet
Pipe die 3 is included, the pipe die 3 is internally provided with chute 1, and 1 surface flow of chute has flowing molten iron 2, and 3 bottom of pipe die is set
It is equipped with pipe die support roller 4,1 side of chute is provided with mould powder cloth packet 6, magnesium grain and mould are housed inside the mould powder cloth packet 6
Powder mixture 5,6 side of mould powder cloth packet are provided with fan-shaped packet 7, and the fan-shaped packet 7 is internally provided with fan-shaped iron clad water 8,
7 bottoms of the fan-shaped packet are provided with pouring truck 9, and 9 side of pouring truck is provided with spray gun 10.
In order to make this kind of novel hot-die Surface of Centrifugal Cast Ductile Pipe liquid iron balling device, easy to use, work efficiency is high, the pipe die
3 is identical as 7 direction of rotation of the fan-shaped packet, and the pipe die support roller 4 is connected with the pipe die 3 by screw and nut.
When the utility model is used, (one) is once blown nodularization, spray gun 10 is inserted into fan-shaped 8 bottom of iron clad water, is utilized
Nitrogen is as carrier, and under 0.4-0.5MPa pressure, the following magnesium grain of 0.2mm granularity is sprayed into molten iron depths by 0.5kg/t dosage,
It is allowed to react under strong stirring condition with molten iron, thus the method for completing spheroidising, a nodularization main function is to make
Slag in molten iron floats, purifying molten iron；(2) it removes the gred, using manually or mechanically mode, molten iron level dross is cleaned out；
(3) second pouring nodularization, using mould powder (0-30 mesh granularity inovulant) as carrier, uniformly magnesium grain is added in mixing, the benefit in casting
With nitrogen, by mould powder, magnesium grain mixture, with injection method, uniformly (magnesium grain additional amount amount is 1.0- to uniform distribution in pipe die mold
1.3kg/t), the nodularization in casting may be implemented, due to greatly shortening nodularization and duration of pouring interval, so ductile iron pipe metallographic
Spheroidizing quality is obviously improved.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
