の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides that the mold wall forming the hollow chamber is brought to the geometrical dimensions of the mold by means of gunpowder and is in the form of a tube made of copper alloy, straight or curved continuous casting. This invention relates to a mold manufacturing method.

51-37828), gunpowder applies force to the mold wall that forms the hollow chamber to deform this wall, and this force deforms the wall to the geometric dimensions of the mold. Manufacturing methods are well known. The advantages of the known method are as follows. That is, the mold made of copper or copper alloy deformed by this method has good surface characteristics and dimensional accuracy inside the hollow chamber. Furthermore, the surface can be hardened by the deformation force. In this case, a starting material having a Rockwell B hardness of 40 can be hardened to a Rockwell B hardness of 50 to 75.

く、また浴鏡面領域に割れ目を形成し易いもので
ある。 The disadvantage of this method is that the explosive deformation causes only a small reduction in the wall thickness and therefore only a small overall cold deformation is possible. This makes the overall strength of the cross-sectional shape of the mold relatively low, and hence the stability of the shape. Another disadvantage of ordinary copper alloys is that the cold hardening achieved by cold deformation is reversed at temperatures above 350°C, and as a result, the durability of molds subjected to high loads is extremely short. Higher strengths are achieved in known methods by using higher alloy types of copper alloys. However, this type of alloy has poor thermal conductivity and tends to form cracks in the bath mirror area.

くできる方法を提示することを課題とする。 The present invention makes it possible to produce molds of any size, for example large-walled tubular molds for processing block forming equipment, which have a very high strength over the entire wall thickness as well as a softening temperature The present invention proposes a method in which the thermal conductivity or electrical conductivity can be made very high or to a limited extent in the case of molds for magnetic stirring, for example, by appropriately selecting the alloy components. That is the issue.
この課題は、本発明により次の様にして解決さ

〜600℃の範囲の温度で少なくとも15分間硬化し、
この管片を最終寸法付けのため最後に爆発成形に
付すという製造方法により解決される。 This problem is solved by the present invention as follows. That is, a hardenable copper alloy is used as a starting material, a tube is made from this copper alloy, the length of the tube is shortened into a tube section, the tube section is solution-treated, and the tube section is then formed into a predetermined shape. , 400 solution-treated tube pieces
Cure for at least 15 minutes at a temperature in the range of ~600℃,
The solution is achieved by a manufacturing method in which the tube section is finally subjected to explosive molding for final dimensioning.
尚、溶体化処理とは合金を硬化可能乃至は変形

における熱応力に対して、形状保存性を増すこと
並びに僅かしか摩耗させない高い耐摩耗性を増す
ことから生ずる。 Molds made in this way have substantially higher strength than molds made in known ways. The reason for this is that a hardenable copper alloy is used as the mold material. In this material,
Heating at 400-600°C increases the strength due to the uniform dispersion effect (hardening) of the alloy components. Improving the properties of the mold will result in a longer life. This increased service life results from increased shape preservation against thermal stresses at relatively high temperatures as well as increased wear resistance with minimal wear.

能である。 In the method of the present invention, the strength can be further increased by mechanically cold deforming the softened tube in a conventional manner after solution treatment. This cold deformation process can be carried out by inserting a mandrel (in the case of a curved tubular mold, a correspondingly curved mandrel) into a tubular mold, and pressing the mold together with the mandrel by a mother mold (die). In this case, the cold deformation rate can be adjusted from 2 to 30% depending on the desired final strength. Because of the locally very high strength values that occur after this subsequent hardening, it is expedient to bring the final geometrical dimensions of the tubular mold already to the correcting time after the solution treatment. In this way, it is possible to remove the distortions that occur during curing in the explosion process, resulting in the best possible final product.

A copper alloy with the balance copper and common impurities is first cast into billets and then continuously cast into tubes at 1030°C. The tube is water-quenched and tube sections are cut from the tube. The tube piece is bent on a bending machine,
A mold with a round cross section is inserted into the hollow space of the tube piece.
On the outside of the tube piece, gunpowder is evenly distributed and ignited. Next, remove the mold from the tube piece and 475
Anneal for 4.5 hours at °C. After cooling, a mold is inserted into the tube piece taken out from the annealing furnace, possibly with some distortion. The cross-section of the mold corresponds exactly to the cross-section of the casting to be cast. In this case, care must be taken to insert the slightly bent mold into the tube so that the direction of curvature of the tube and the direction of curvature of the mold are in the same direction.

項に記載の方法。[Scope of Claims] 1. A method for manufacturing a straight or curved continuous casting mold made of a copper alloy and having a tubular shape, in which the walls of the mold forming a molding cavity are deformed by explosives, the starting material Using a copper alloy that can be hardened as The treated pipe piece
A process characterized by curing for at least 15 minutes at a temperature in the range from 400 to 600°C and finally subjecting the tube piece to explosive forming for final dimensioning. 2. The method according to claim 1, wherein the shaping is performed by a cold working method. 3. A method as claimed in claim 2, characterized in that a mandrel is introduced into the tube piece and then the tube piece is pressed by a matrix for cold deformation of the mandrel together. 4 Copper alloys contain 0.3-1.2% chromium and 0.05% by weight
One of claims 1 to 3, characterized in that ~0.2% by weight of zircon is used.
The method described in section.
