Abstract
The invention discloses a dummy ingot sealing method capable of preventing casting leakage of a shaped blank, which is used for overcoming the defect that scrap iron is easily burst easily and avoiding the condition that a paper rope contacts molten steel to be burned. A gap between a dummy ingot head and a crystallizer is filled with wool felt and an asbestos rope, the asbestos is sealed on the wool felt; scrap iron is uniformly paved on the surface of the dummy ingot head; small cold iron rods are paved on the surface of the scrap iron in a scattering manner. According to the method, the small cold iron rods are paved on the surface of the scrap iron of the dummy ingot head, the dummy ingot is sealed by the combination of the wood felt and the asbestos rope, the small cold iron rods are used for preventing the molten steel from bursting the scrap iron during casting, and the asbestos rope can be used for preventing the high-temperature molten steel from burning the wool felt, so that the leakage during casting can be avoided.
Description
Technical field
The invention belongs to continuous beam blank casting production technical field, be specifically related to a kind of envelope dummy ingot method that can prevent from shaped blank casting machine from opening watering seepage.
Background technology
Envelope dummy ingot is a key operation step during steel plant continuous casting is produced, and the envelope dummy ingot method generally adopted at present seals dummy ingot with paper string, and spills iron filings dummy bar head surface uniform paving, and object is the gap preventing molten steel from infiltrating dummy bar head and crystallizer.But due to open water Shi Gang stream percussion under iron filings may be rushed to open, can be burnt after paper string runs into molten steel, thus cause molten steel to infiltrate the gap of dummy bar head and crystallizer, cause to open and water seepage, have a strong impact on production.Chinese patent application CN101992279A discloses a kind of envelope dummy ingot method, employing be paper string envelope dummy ingot, spill iron filings dummy bar head paving, there is the possibility that iron filings are rushed to open scaling loss paper string in this method, may cause opening watering seepage.The disclosed another kind of envelope dummy ingot method of Chinese patent application CN101890487A, what adopt is asbestos cord envelope dummy ingot, spill iron filings dummy bar head paving, this method, when iron filings are rushed to open, still may be opened at the weakness of envelope dummy ingot asbestos cord and water seepage.Envelope dummy ingot method in " Measures for Controlling Breaking-out in Cast Starting " document, employing be paper string envelope dummy ingot, dummy bar head paving spill iron filings, there is the possibility that iron filings are rushed to open scaling loss paper string in this method, still may cause opening watering seepage.
Summary of the invention
The object of the invention is a kind of openly envelope dummy ingot method preventing from shaped blank casting machine from opening watering seepage, in order to overcome the deficiency that iron filings are easily rushed to open, paper string is avoided to contact molten steel and be burnt, the present invention adopts the little chill rod of the iron filings scattered lay in surface on dummy bar head, and wool felt is in conjunction with asbestos cord envelope dummy ingot.Little chill rod prevents from opening molten steel when watering and is washed open by iron filings, and asbestos cord can prevent high-temperature molten steel by wool felt scaling loss, avoids opening when watering seepage occurs.
For reaching above-mentioned purpose, the present invention is a kind of can prevent from shaped blank from opening watering the envelope dummy ingot method of seepage, comprises the following steps:
1) fill gap between dummy bar head and crystallizer with wool felt in conjunction with asbestos cord, and asbestos cord is enclosed in above wool felt;
2) iron filings are spilt dummy bar head surface uniform paving;
3) at the little chill rod of the iron filings scattered lay in surface.
Wherein said little chill rod material is QB class steel making, and length is 30-40mm.
The invention difference from existing technology is that the present invention achieves following technique effect:
The present invention, by design little chill rod of scattered lay on the iron filings on dummy bar head surface, opens molten steel when watering and meets little chill rod just quick solidification, can prevent and treat molten steel and be washed open by iron filings.And front cover layer asbestos cord again above the wool felt at the gap place between dummy bar head and crystallizer, asbestos cord is high temperature resistant can be prevented from running into molten steel scaling loss further.The present invention can prevent from opening and water generation seepage, Be very effective.
Below in conjunction with accompanying drawing, the invention will be further described.

Detailed description of the invention
Below in conjunction with embodiment, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.
See Fig. 1 and 2, a kind of method preventing from opening the shaped blank envelope dummy ingot watering seepage when casting blank section is 555 × 440 × 105, the method comprises the following steps:
1) on dummy bar head 1, put into the king bolt bar 2 that two are played connection function, in the side of dummy bar head 1, steady pin 3 is squeezed into;
2) at a dummy bar head 1 surface paving wool felt 4, on wool felt 4, a pressing plate 5 is spread;
3) two king bolt bars 2 are overlapped upper bush 6, sleeve 6 is installed pad 7, mounting nuts 8 on pad 7 is tightened;
4) wool felt 4 of dummy bar head 1 surrounding is enclosed the gap between dummy bar head 1 and crystallizer, and on the wool felt 4 enclosed front cover layer asbestos cord 9 again;
5) at dummy bar head 1 surface paving thickness 30mm iron filings 10;
6) at the little chill rod 11 of the surperficial scattered lay length 30-40mm of iron filings 10.
Of the present invention focus on dummy bar head surface iron filings above scattered paving add little chill rod and prevent iron filings from being washed open by molten steel.With wool felt in conjunction with asbestos cord envelope dummy ingot, asbestos cord is enclosed in above wool felt, and asbestos cord is high temperature resistant prevents scaling loss.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
Claims (2)
1. can prevent from shaped blank from opening watering an envelope dummy ingot method for seepage, it is characterized in that comprising the following steps:
1) fill gap between dummy bar head and crystallizer with wool felt in conjunction with asbestos cord, and asbestos cord is enclosed in above wool felt;
2) iron filings are spilt dummy bar head surface uniform paving;
3) at the little chill rod of the iron filings scattered lay in surface.
2. the envelope dummy ingot method that can prevent from shaped blank from opening watering seepage according to claim 1, is characterized in that: described little chill rod material is QB class steel making, and length is 30-40mm.
