Abstract
Description
本發明係針對一種藉由具有盒形壁和底板的鑄模具製造金屬或非金屬熔融產品之方法，其中提供熔融產品以藉粉碎進一步加工。The present invention is directed to a method of making a metal or non-metal molten product by a casting mold having a box-shaped wall and a bottom plate, wherein a molten product is provided for further processing by pulverization.
文中主要針對之所謂的熔融產品是指，例如用於冶金術(如，矽鐵、錳鐵或鉻鐵)的合金化裝置。The so-called molten product mainly referred to herein means, for example, an alloying device for metallurgy (for example, ferroniobium, ferromanganese or ferrochrome).
大部分的金屬和非金屬熔融產品於進一步加工之前(如，藉破裂、研磨、篩選..等)在模具中模製。以前使用的鑄模有時製成單片或製成包含多個零件和底板的框。Most of the metal and non-metal molten products are molded in a mold prior to further processing (eg, by cracking, grinding, screening, etc.). Previously used molds were sometimes made in a single piece or as a frame containing multiple parts and a bottom plate.
單片鑄模製自，例如，鑄鐵。此模具藉由傾斜或者以大鉗上提熔融產品而掏空。Monolithic molds are made, for example, from cast iron. The mold is hollowed out by tilting or lifting the product with a tong.
多零件鑄模包含具有四個壁部件用以形成矩形並站在底板上的框。在固化之後，藉大鉗移動熔融產品，事先開啟框部件。The multi-part mold includes a frame having four wall members for forming a rectangle and standing on the bottom plate. After curing, the molten product is moved by a tongs, and the frame member is opened in advance.
此二系統常發生熔融產品部分在運送或在拿取時(即，在確實進一步加工之前)破裂的情況。These two systems often occur where the molten product portion breaks during transport or when it is taken (ie, before it is indeed further processed).
亦常發生於此二鑄模的情況係傾倒熔融產品時因洗除而造成底板磨損。It is also the case that the two molds often occur when the molten product is poured and the bottom plate is worn due to washing.
至於鑄模，此意謂必須交換整個模具，而在鑄模包含多個零件的情況中，必須置換底板。As for the mold, this means that the entire mold must be exchanged, and in the case where the mold contains a plurality of parts, the bottom plate must be replaced.
交換整個鑄模或底板意謂製造碎片，此代表財務損失且必須清除。此外，自鑄模洗除的材料通常與熔融產品混合，使得在一些情況中，熔融產品會受到所不欲的污染。Exchange of the entire mold or bottom plate means manufacturing debris, which represents financial loss and must be removed. In addition, the material that is washed from the mold is usually mixed with the molten product, so that in some cases, the molten product may be undesirably contaminated.
本發明的目的是防止或至少實質上緩解前述代表商業成本因素的缺點。It is an object of the present invention to prevent or at least substantially alleviate the aforementioned disadvantages of representing a commercial cost factor.
根據本發明達到的此目的在於先自熔融產品鑄造可再使用的底板，在於在此底板固化之後，鑄模置於底板上，脫模劑施於底板上之至少鑄模的區域，及之後將對應於底板的熔融產品倒入鑄模中。This object achieved in accordance with the invention consists in first casting a reusable base plate from a molten product, after the base plate has been solidified, the mold is placed on the base plate, the release agent is applied to at least the region of the mold on the base plate, and thereafter corresponds to The molten product of the bottom plate is poured into the mold.
脫模劑防止底板材料與倒入鑄模中的熔融產品之間的熔融連接，以有助於底板和具有固化的熔融產品位於其中的鑄模框的後續分離。The release agent prevents a fusion bond between the backing material and the molten product poured into the mold to aid in the subsequent separation of the bottom plate and the mold frame with the cured molten product therein.
以使用鑄造材料作為脫模劑為佳。所謂的鑄造材料是指熔融產品的後續粉碎得到的細塵。收集此細塵及之後散佈在鑄模，固化的底板，特別是至少散佈在鑄造框將放置或已放置的區域。It is preferred to use a cast material as a release agent. The so-called foundry material refers to fine dust obtained by subsequent pulverization of the molten product. This fine dust is collected and then spread over the mold, and the cured substrate is, in particular, at least spread over the area where the casting frame will be placed or placed.
此外，建議在開始填充鑄模時，此脫模劑，細塵，藉鑄造流敲擊而堆積在鑄造框內的區域。此防止熔融物嚴重滲透進入底板。In addition, it is recommended that the release agent, the fine dust, be deposited in the area inside the casting frame by the casting flow when the mold is started to be filled. This prevents the melt from penetrating heavily into the bottom plate.
鑄模中的熔融產品固化之後，此鑄模自底板上提，與位於其中的熔融產品一起運送至用於進一步加工之處，於此處先分離鑄模和熔融產品。After the molten product in the mold is cured, the mold is lifted from the bottom plate and transported with the molten product located therein for further processing where the mold and molten product are first separated.
此鑄模包含於之後互相獨立的盒形壁和底板。此盒形壁在底板方向上錐形寬化。鑄模以矩形為佳。The mold contains box-shaped walls and bottom plates that are independent of each other. This box-shaped wall is tapered in the direction of the bottom plate. The mold is preferably a rectangle.
鑄造框內側的錐形使其能夠在熔融產品固化之後與框一起運送。因此，不須在進一步加工之前，如，藉懸浮於鑄造起重機上的大鉗，自框移動熔融產品。The taper on the inside of the cast frame enables it to be shipped with the frame after the molten product has cured. Therefore, it is not necessary to move the molten product from the frame before further processing, for example, by means of a tongs suspended on a casting crane.
據此，鑄造框的形狀使得固化的熔融產品以安全鑄造且無廢料的方式運送。Accordingly, the shape of the cast frame allows the cured molten product to be shipped in a safe cast and free of waste.
因不再使用大鉗而使得固化的熔融產品之運送被簡化；當上提鑄模和運送時，熔融產品塊不會破裂。The transport of the solidified molten product is simplified by the fact that the tongs are no longer used; the molten product pieces do not break when the mold is lifted and transported.
以此方式，因為底板製自適於銷售的材料(產品本身)且未製得碎片，所以使得底板的投資成本無耗損，故材料浪費實質降低且達到工作安全改良。In this way, since the bottom plate is made of a material suitable for sale (the product itself) and no chips are produced, the investment cost of the bottom plate is not depleted, so material waste is substantially reduced and work safety improvement is achieved.
事先自熔融產品鑄造的底板代替常用但非源自於產品的鐵材料板(鑄鋼、鋼板)。The bottom plate cast from the molten product is previously replaced with a sheet of iron material (cast steel, steel plate) which is commonly used but not derived from the product.
底板製自與熔融產品相同的材料的事實防止熔融產品被，例如，自底板熔解的鐵，所污染。當然，因為此脫模劑也是源自於產品本身的材料，所以此情況亦適用於脫模劑。The fact that the soleplate is made of the same material as the molten product prevents the molten product from being contaminated by, for example, iron melted from the soleplate. Of course, since the release agent is also a material derived from the product itself, this also applies to the release agent.
此外，因為沒有等待運送的時間，所以能夠迅速地交換底板。In addition, since there is no waiting time for transportation, the bottom plate can be exchanged quickly.
使用自與熔融產品相同的材料製得的底板不僅因為未製造碎片及底板製自可銷售的產品而節省底板的投資成本，同時也意謂因為不假外力地鑄造置換的底板而易取得置換的底板。The use of a base plate made of the same material as the molten product not only saves the investment cost of the base plate because the unfinished chips and the bottom plate are made from a marketable product, but also means that the replacement of the replacement base plate is easy to obtain the replacement. Base plate.
下文將參考體系例地描述本發明。The invention will be described hereinafter with reference to the system.
此二圖式中，典型的鑄造桌以1代表。底板2先置於此鑄造桌上。在習知方法中，此底板2製自鋼片或鋼板，根據本發明之溶液則是使用配備耐火襯料4的鋼管3。熔融產品先倒入此管中，使得熔融產品於固化之後形成底板5。In the two figures, a typical casting table is represented by 1. The bottom plate 2 is placed first on this casting table. In the conventional method, the bottom plate 2 is made of a steel sheet or a steel sheet, and the solution according to the present invention is a steel tube 3 equipped with a refractory lining 4. The molten product is first poured into the tube such that the molten product forms the bottom plate 5 after curing.
之後施用前述脫模劑。此亦可於鑄模已置於藉其覆蓋的區域中之後進行。此二情況中，之後將鑄模6或鑄造框置於底板2或5上且再度將熔融產品倒入其中。The aforementioned release agent is then applied. This can also be done after the mold has been placed in the area covered by it. In either case, the mold 6 or casting frame is then placed on the bottom plate 2 or 5 and the molten product is again poured therein.
如前述者，基本差異在於在習知方式中，傾倒的熔融產品和底板製自不同材料，而在根據本發明中則為相同材料。As mentioned above, the basic difference is that in the conventional manner, the poured molten product and the bottom plate are made of different materials, and in the present invention are the same material.
鑄模中的熔融產品中固化之後，此鑄模和位於其中的熔融產品自底板上提並與後者一起運送至進一步加工處，鑄模和熔融產品於此處分離並藉破裂、研磨之類地進行粉碎。After solidification in the molten product in the mold, the mold and the molten product located therein are lifted from the bottom plate and transported to the further processing place together with the latter, where the mold and the molten product are separated and pulverized by cracking, grinding or the like.
如前述者，收集藉粉碎製得的細塵並使用作為脫模劑。As described above, the fine dust obtained by the pulverization is collected and used as a release agent.
