Abstract
The utility model discloses a forming mould of a ceramic composite type whole stopper rod head. The forming mould is characterized in that a mould core is included, a circular-table-shaped bottom plate is arranged at the bottom of the mould core, a cylindrical rod body is vertically arranged upwards at the center of the upper face of the bottom plate, a cone-shaped protrusion is arranged at the top end of the rod body, a mould sleeve is arranged on the outer side of the bottom plate in a sleeved mode, the mould sleeve and the bottom plate are matched, a rod head mould is arranged above the mould sleeve, the rod head mould is matched with the mould sleeve, a casting opening is formed in the center of the upper face of the rod head mould which is provided with an inner cavity in a cone shape, and a cover plate is arranged above the casting opening. According to the technical scheme, the stopper rod head can be directly formed, the labor productivity of workers can be improved, rod head turning procedures during a stopper rod manufacturing process can be reduced, raw materials are saved, a compact layer is formed on the surface of the stopper rod head, and the service life of a product is effectively prolonged.
Description
Technical field
The utility model relates to refractory material mould field, is specifically related to a kind of mould of ceramic combined integral stopper rod head.
Background technology
Integral column of sagger is installed on tundish, coordinates with built-in type submersed nozzle or tundish upper nozzle, controls molten steel from tundish to crystallizer flow in continuous casting process, to guarantee molten steel liquid level stabilizing and continuous casting process stable in crystallizer.Determine that stopper rod flow control function and the key position in service life are stopper caputs, stopper caput is taper shape, first molds columniform integral column of sagger in production process, processes the conical caput of stopper after burning till on lathe by drawing.Caput is in Vehicle Processing process, and whether operator will meet drawing requirement with template comparison caput at any time, until all meet the requirements.Simultaneously, when Vehicle Processing stopper caput, operator wants the prudent controlled working depth of cut, and can not feed excessive and make the impaired waste product that causes of stopper caput, operator's operating efficiency be lower.
In manufacture ceramic combined integral stopper rod process; because the material of barred body and stopper head is inconsistent; it in forming process, is separately moulding; after moulding by barred body and stopper head with after the pressure of 100-130MPa etc. static pressure 5-8 minute; under restitutive protection's atmosphere, 1000-1400 degree heat treatment 4 hours.Barred body without pressure forming, needs the pressure forming of 30-100MPa in forming process at stopper head, and forms by a firing under 1700 degree.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of caput high pressure straight forming, without machining, and the mould of the ceramic combined integral stopper rod head of long service life.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of mould of ceramic combined integral stopper rod head, comprise a core rod, described core rod bottom is the base plate of a truncated cone-shaped, and above described base plate, center is provided with a columniform body of rod straight up, and described body of rod top is also provided with a conical projection; Described plate outer side is arranged with a die sleeve, and described die sleeve and described base plate are suitable; Described die sleeve top is provided with a caput mould, and described caput mould and described die sleeve are suitable, and above described caput mould, center is provided with sprue gate, and it is conical that the inner chamber of described caput mould is; Top, described sprue gate is provided with cover plate.
By technique scheme, the utility model beneficial effect is:
1, can by stopper head straight forming out, improve workman's labor productivity, reduce the caput Vehicle Processing operation in stopper manufacturing process, save raw material, and eradicated the waste product causing due to Vehicle Processing caput.
2, because cast raw material is 50%, zirconia adds 50% zircon sand, and in 30-100MPa pressure forming, stopper head surface forms one deck compacted zone, has effectively extended product service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the mould of the disclosed a kind of ceramic combined integral stopper rod head of the utility model embodiment.
Numeral and the represented corresponding component title of letter in figure:
1. core rod 2. base plate 3. body of rod 4. projection 5. die sleeve 6. caput mould 7. sprue gate 8. cover plates.
The specific embodiment
Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.
Embodiment.
As shown in Figure 1, a kind of mould of ceramic combined integral stopper rod head, comprise a core rod 1, described core rod 1 bottom is the base plate 2 of a truncated cone-shaped, described base plate 2 is provided with a columniform body of rod 3 in center above straight up, and the described body of rod 3 tops are also provided with a conical projection 4; Described base plate 2 outsides are arranged with a die sleeve 5, and described die sleeve 5 is suitable with described base plate 2; Described die sleeve 5 tops are provided with a caput mould 6, and described caput mould 6 is suitable with described die sleeve 5, and described caput mould 6 is provided with sprue gate 7 in center above, and it is conical that the inner chamber of described caput mould 6 is; 7 tops, described sprue gate are provided with cover plate 8.
Preferably, the zirconia that the cast raw material of the mould of described ceramic combined integral stopper rod head is 50% adds 50% zircon sand, and the briquetting pressure of the mould of described ceramic combined integral stopper rod head is 30-100MPa.
By technique scheme, the utility model beneficial effect is:
1, can by stopper head straight forming out, improve workman's labor productivity, reduce the caput Vehicle Processing operation in stopper manufacturing process, save raw material, and eradicated the waste product causing due to Vehicle Processing caput.
2, because cast raw material is 50%, zirconia adds 50% zircon sand, and in 30-100MPa pressure forming, stopper head surface forms one deck compacted zone, has effectively extended product service life.
The preferred embodiment of the above-described mould that is only a kind of ceramic combined integral stopper rod head of the present utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
