Description
Technical field
The utility model relates to the ladle in a kind of casting technique, is specifically related to a kind of ladle that is used for spheroidal graphite cast-iron is carried out spheroidising.
Background technology
Spheroidising is an important process procedure during spheroidal graphite cast-iron is produced, and adopts which kind of spheriodization process thereof to be directly connected to complicated and simple, equipment drops into what, the height of nodularization cost and the quality of operating environment of the height of nodularization quality and stable, technological operation.The ferrosilicon magnesium-rare earth alloy pours the method spheriodization process thereof and is widely used ductile iron production from the sixties in last century owing to having advantages such as equipment is simple, easy to operate.Nearly half a century, though the method spheroidizing process of pouring has continuous improvement, as the improvement that covers iron filings and little steel plate and nodularization alloy on the improvement of adopting nodularization chamber in the big special-purpose nodularization bag of ratio of height to diameter, the bag, the nodularization alloy etc., basic condition does not change.Compare its weak point with various new spheroidizing process and more appear, mouthful open wide as bag, in the air in oxygen and the iron liquid reactive magnesium unrestricted, make a large amount of scaling loss of nodularization element, not only increase the consumption of nodulizer, also produce a large amount of smog and magnesium light, serious environment pollution.And electric furnace when toppling over iron liquid because the variation of drop point also makes nodularization quality instability, be difficult to satisfy the requirement that the high-quality iron casting is produced.Make a general survey of American-European developed country, progressively eliminate traditional " sandwich " method (being that uncovered bag pours method) spheroidizing process since the eighties, then employing is covered the bag method, feeds a silk method, is subcontracted advanced persons' such as method spheriodization process thereof, to the end of the nineties, almost pour method with uncovered bag seldom again and carry out spheroidising.And domestic cast iron enterprise even to this day, and is still most of for various reasons with pouring the method spheroidising.
Spheriodization process thereof commonly used at present has: pour method, lid bag method, feed the silk method, subcontract method, plunging etc. in method, the type.Adopt which kind of spheroidizing process will be according to the kind and the quality requirement of enterprise's foundry goods, melting process and production equipment condition etc. be taken all factors into consideration.For making foundry enterprise select suitable spheroidizing process better for use, need various spheroidizing process pluses and minuses are done a contrast, see Table 1.

Annotate: 1. plunging refers to adopt self-built pressure nodularization bag to handle herein.
2. the original iron melt sulfur content can be relaxed during cupola melting, but must many consumption nodularization alloys or nodularization alloy claded wires.
In above 6 kinds of spheriodization process thereofs, method need be special to the Design of Runner System of different foundry goods in the type spheroidizing reacion chamber and pushing off the slag measure, make product yield and casting mold arrange that the usable area of die cavity greatly reduces, and for preventing to be mingled with generation, require sulfur content＜0.01% of original iron melt, important foundry goods also must 100% be carried out intrinsic shortcomings such as nodularization rate detection,, use producer also seldom even in American-European developed country.
Plunging is early stage spheriodization process thereof, and impressed pressure still is that self-built pressure method all exists troublesome poeration, and the processing time is long, and iron liquid temperature drop is big, and security is relatively poor to be waited inherent defect and progressively abandoned.
Core-spun yarn feed a silk method be the later stage eighties Germany, the U.S. come from the technology transplant of metallurgy industry liquid steel refining to spheroidizing process, because of it can realize that accurately control nodularization alloy adds and the advantage of automated job obtains widely-used at American-European foundry enterprise according to the weight of iron liquid and metallurgical quality.Domestic my company took the lead in feeding the silk method with core-spun yarn and is applied to handle in the press pouring furnace iron notch iron blast pipe iron liquid of wriggling in 95 years, once investment in 2004 is built interior hello the pompon work of treatment station of bag and is manufactured experimently, but because of wire feeder and electric-control system poor quality fault frequent, clad sealing difference and iron liquid splash problem such as serious and the batch process of failing to have high input.Show that from the situation of trial-production this technology is subjected to the influence of factors such as wire feeder system, core-spun yarn quality and wire feeding process bigger, core-spun yarn magnesium content height and spheroidizing reacion is very fierce, magnesium absorption rate not high (even being lower than the method for pouring), operating process is comparatively complicated.Though can be by make great efforts improving the problems referred to above, total spheroidising cost pours the method height, seems some luxury for the big common magnesium iron spare of price competition pressure.Not credulous some article is about feeding silk method magnesium absorption rate height, cost-saved saying.Our practice shows as a kind of new spheroidizing process, feeding the silk method is more suitable in technology content, quality requirement, iron casting that the magnitude of value is high, be particularly useful in the wriggling processing of control range strictness, but good hardware device, core-spun yarn and technology controlling and process must be arranged.
Except pouring method, domestic and international widely used spheroidizing process mainly is exactly to cover bag method, hello silk method and GF to subcontract 3 kinds of methods at present.Wherein subcontract method owing to adopt pure magnesium nodulizer, the nodularization quality is good and stable, can directly handle the high furnace cupola iron liquid of sulfur content, if it is be equipped with that band verts and process chamber that the dedicated processes fork truck of weighing or dedicated processes crane and band are taken out dirt can be formed efficiently, the mechanization system of big disposal ability, therefore more in the application of European massive casting enterprise.Companies such as existing at home emerging cast tube, Kunshan GF casting adopt, but this complex process equipment, supporting requirement is high, the expense that once drops into is big, every bag all will be cleared up nodularization chamber and dividing plate hole during processing, and sealing nodularization chamber cap is subcontracted interior residue clearly, therefore the operation more complicated is applicable to that the single treatment amount is big, economic strength and the strong massive casting enterprise of technical capability.
Lid bag method is the spheriodization process thereof that develops on the basis of method pouring, and has overcome the shortcoming that the method that pours exists substantially, and its basic principle is to wrap in the method nodularization of pouring to install a lid additional.Therefore operating process with pour method roughly the same, nodulizer and auxiliary material and production corollary equipment do not need to change substantially, for adopting uncovered bag to pour the middle-size and small-size foundry enterprise of method spheroidising, only need acquire when changing the spheroidising of lid bag into and add a cover the spheroidising bag and get final product, be fit to China's national situation, be easy to apply.
Because lid bag method has the listed advantage of table 1, is generally used already in American-European developed country foundry enterprise.Though domestic have some producers to adopt, and the trend of increase is arranged, quantity is few, and scope is wideless.Hinder the subject matter of covering the use of bag method to be, though it with subcontract method, feeding a silk method, to compare equipment simple, easy to operate, but compare with the method for pouring, to bother in the technological operation, as the folding of clad, iron liquid quantitatively, the scarfing cinder in clad hole, the cleaning of skimming, wrapping or covering is built and baking bag etc.Must when selecting lid bag type and design cover bag, consider how to make more convenient operation, otherwise can hinder and cover using and promoting of bag method.
Add a cover the bag type abroad and mainly contain 4 kinds of fixed clads, movable clad, lift clad, teapot formula pack processing.Fixed and clad teapot formula pack processing all is fixed on the inclusion, can not arbitrarily open, and can't take off slag operation, and under the relatively poor and higher situation of iron molten sulfur amount of quality of furnace charge, accumulated slag is serious in the bag at home, and the nodularization bag can not use very soon.We once at home certain foreign capitals Foundry Inc. see the use of teapot formula pack processing, not only clear bag being built job contract and doing very heavyly, and because the big iron mouth that advances opens wide, and magnesium light smog is a lot, the nodulizer addition can not reduce.
Therefore, though it is fairly simple to add a cover bag, prior art is still unexposed can to adapt to various working conditions and the easy to operate product of contracting for fixed output quotas of adding a cover, and has influenced applying of this technology.

In order to implement the utility model better, introduce the utility model below and add a cover nodularization and wrap in the several problems that note in the design and use.
1, when the design clad, the liquid-leaking nozzle size of clad must guarantee to be covered by iron liquid in whole spheroidizing reacion process, the aperture is excessive, it is open that reaction does not finish liquid-leaking nozzle, magnesium steam is escaped can influence the absorptivity of magnesium, the aperture is too small, dashes the bag overlong time and can increase iron liquid temperature drop, and the prolongation operating time also is unfavorable for nodularization.Pore size should make the interior iron liquid of iron liquid basin flow to end for good when spheroidizing reacion finishes.The computing formula of the general liquid-leaking nozzle pore size that adopts is now:
In the formula: W---handle iron liquid weight (kg); T---iron liquid is through the flowing hole time (second); Iron hydrostatic pressure head (cm) in h---the clad.
This formula is to be derived by evangelista torricelli small hole stream theorem, and setting fluid friction loss coefficient ψ during derivation is 0.85.According to our practice, for iron liquid, it is 0.75 more suitable to be made as, therefore, and the diameter of liquid-leaking nozzle
More realistic.
During 2, owing to spheroidising, magnesium steam can be set up certain pressure between iron liquid level and clad, for making a large amount of escapes of jack-up clad of magnesium steam, except leaving enough spaces, also will rely on the deadweight of clad and the iron liquid weight in the clad to push down.Therefore clad must have bigger deadweight, and it is enough big and enough high that the iron liquid basin at clad top is wanted, and to hold more iron liquid, this point is even more important for movable clad.Not so magnesium light and flue gas can part be escaped, and influence environment and magnesium absorption rate.
3, for increasing the sealing property of clad, clad must all cover the inclusion upper edge, and therefore, the utility model is made seal groove at the binding site of clad and inclusion, and serve as a contrast with high temperature resistant elastic sealing gasket, not so also can make a large amount of escapes of gaseous magnesium and flue dust and influence environment and magnesium absorption rate.
4, add a cover to note when bag is handled operation following some:
● before tapping a blast furnace, iron liquid will eliminate slag in the stove, in order to avoid slag stops up the clad liquid-leaking nozzle, all will observe the liquid-leaking nozzle situation before simultaneously every bag is handled, and the discovery dross will in time be removed.
● want enlargement discharge when beginning to tap a blast furnace, in iron liquid basin, set up liquid level rapidly, keep liquid level constant then as far as possible.
● still need cover little steel disc on the nodulizer in the inclusion,, improve the nodularization effect to postpone the spheroidizing reacion outburst.
● spheroidizing reacion finishes the back and does not remove clad, can be transported to cast place of skimming and get clad again to reduce contacting and temperature drop of iron liquid and air at once.
