Abstract
The method of up-lead continous casting of reduced billets and crystallizer, what relate to is continuous casing and its specialized apparatus accessory.
Adopt continuous casting process still not have to cast out the report of reducing strand in the prior art.Purpose of the present invention just provides a kind ofly utilizes existing led-up continuous casting machine to realize casting out the method for reducing strand and the technical scheme of its special crystallizer.
Characteristics of the present invention are that its crystallization cavity of crystallizer of using is a reducing, make crystal region upper and lower continuously moving in the crystallization cavity of reducing with this crystallizer by the chilling temperature of controlling casting speed and crystallizer, the diameter or the sectional area that reach strand change on demand.
Description
What the present invention relates to is continuous casing and its specialized apparatus, draw on especially the method for continuous casting reducing strand and this method special-purpose crystallizer.
The processing of reducing blank also has only at present with single piece type casting, die casting, forging and pressing or machined way and realizes, still the end retrieves the argumentation of drawing continuous casting process acquisition reducing strand method in the utilization so far.
The objective of the invention is to disclose a kind of use draw the continuous casting means on conventional and can cast out the method for reducing strand and realize the reducing strand special-purpose crystallizer, reach and draw continuous casting process in the utilization and obtain the reducing strand.
Method of the present invention is to realize like this, be that the lead speed by regulating strand and the chilling temperature of crystallizer are controlled the position of strand crystal region in crystallizer reducing crystallization cavity at the specific process that draws on the continuous casting equipment casting reducing strand on the routine.This crystal region position can be moved on to the chamber, big footpath on crystallizer top by the path chamber of crystallizer bottom on continuously, and perhaps the crystal region position is moved down into the path chamber of crystallizer bottom continuously by the chamber, big footpath on crystallizer top.When the crystal region of strand in crystallizer was in the position, chamber, big footpath of crystallizer, what cast out was major diameter tubing base or heavy in section bar base, and crystal region is in the position, path chamber of crystallizer, the time then cast out minor diameter pipe or small bore rod base.Because strand diameter or sectional area that therefore crystal region is controlled continually varying casts out just can realize from large to small that perhaps changing from small to big becomes the reducing strand.As for the position of crystallization control district in crystallizer, all technique known concerning the professional and technical personnel.
Cast the special crystallizer that the reducing strand must use the unified design of the present invention with the inventive method.This special crystallizer also possesses the overcoat, crystallization cavity of conventional crystallizer and the stem stem that the casting pipe needs, and to be crystallization cavity have at least in its special place two chambeies of not waiting directly or sectional areas.The Lower Half of this crystallization cavity is made the path chamber of minor diameter or small bore, and major diameter or chamber, heavy in section big footpath are then made by half one thereon.Connecting portion in the path chamber with chamber, big footpath can suddenly change, and also can one diameter or sectional area continually varying adapter cavity be arranged at connecting portion.
Use method of the present invention and special-purpose crystallizer drawing on the routine on the continuous casting equipment, can cast out the blank that strand diameter that prior art can't realize or sectional area change.Picture is down thick go up flagpole past of subfractionation can't cast form, can realize easily with technology of the present invention now.There is blank also can adopt the present invention's cast form in a cluster again, promptly reduced processing capacity and also saved a large amount of raw material as the lock core class has slightly, thin step changes.This shows that it is extremely significant implementing good effect of the present invention.
Description of drawings:
Fig. 1 is used to cast two kinds of diameter reducing pipes for special crystallizer of the present invention, and the cross-sectional schematic of a kind of embodiment of adapter cavity is arranged at big chamber, footpath and path chamber link position;
Fig. 2, be the schematic top plan view of Fig. 1;
Fig. 3 is used to cast the reducing bar base of two kinds of sectional areas for special crystallizer of the present invention, is the cross-sectional schematic of a kind of embodiment of suddenling change to the path chamber in chamber, big footpath;
Fig. 4 is the schematic top plan view of Fig. 3.
Now the present invention is further elaborated by embodiment in conjunction with the accompanying drawings.Drawing on the routine on the continuous casting equipment,, controlling the position of strand crystal region in crystallizer reducing knot chamber, reaching the variation of strand diameter or sectional area by the lead speed of adjusting strand and the chilling temperature of crystallizer.This its crystallization cavity of crystallizer with reducing crystallization cavity will have two footpaths, unequal chamber or sectional area at least.Now provide two embodiment.Fig. 1 and Fig. 2 provide a kind of tube blank mould that is used to cast two kinds of vary in diameter, and it is by overcoat 1, chamber 3, big footpath in stem stem 2 and the crystallization cavity, path chamber 5, by chamber, big footpath 3 to there being the continuous adapter cavity 4 from large to small of a diameter to constitute the path chamber 5.The crystal region of strand can be controlled at earlier and cast out at this moment the major diameter pipe in the chamber, big footpath 3 when casting, and the crystallization control district moves downwards continuously then.When crystal region enters adapter cavity 4 by chamber, big footpath 3, the strand diameter dwindles continuously along with moving down continuously of crystal region.After crystal region entered path chamber 5, strand then became the minor diameter pipe.The crystallization control district does reverse to move also passablely continuously with above-mentioned, just casts out the minor diameter pipe earlier, casts out the major diameter pipe then, all can realize the casting of reducing pipe, as can cast out down slightly upward the flagpole of subfractionation etc. with this method.Fig. 3, Fig. 4 then provide a kind of embodiment that is used to cast the variable excellent billet crystallizer of two kinds of sectional areas.It is to be made of chamber, big footpath in overcoat 6 and the crystallization cavity 7 and path chamber 8, suddenlys change between path chamber 8 in chamber 7, big footpath, does not have adapter cavity.The excellent base that casts out like this is long-pending in the heavy in section, and the variation between long-pending has a step of sudden change to small bore, is very suitable to the blank of casting as lock core one class.
Utilize technical scheme of the present invention, as long as control strand well in crystallizer, moving of crystal region just can cast out various spheries continuously, the strand of a string continuous spherical or a string continuous shapes such as cylinder, this processing to some product provides preferable blank.This technical scheme also can be generalized in level and the following continuous cast method that draws, so the present invention is a kind of up-and-coming technical conceive except that can realizing in continuous up-casting.
