Description of the invention (/) The present invention relates to a hardenable copper alloy, especially for the manufacture of wide side plates for continuous casting devices of thin steel plates. In the conventional technology, the wide side plate of the ingot mold for thin steel plate equipment-especially the CSP (Compact Strip Production) equipment is made of copper alloys such as CuCrZr (copper-chrome) or CuAg (copper-silver) Made of alloy. Here, it is advantageous to use a CuAg alloy because it expands greatly as the temperature rises. However, the wide side plate of the ingot mold made of CuAg or CuCrZr cannot withstand the high temperature force in the area of the level surface of the "casting metal liquid", and it is easy to form cracks in the plate in this area. Especially, CuCrZr is easier to Cracks have been formed early. Such cracks are the standard for the failure of the wide side plates of the ingot mold, and it costs large repair and replacement costs for the continuous casting equipment industry. Therefore, we can see that although CuAg has a small tensile strength, it is less likely to form cracks, because it has a larger expandability in the ingot template at high temperatures, so it can eliminate stress, and because of its high thermal conductivity, Its average operating temperature remains low. In the conventional technique, the narrow side plate of the thin steel plate ingot mold is generally used with 125 HB CuCrZr. Among them, nickel is added to the side contact surface to increase the hardness. The failure standard of the narrow side plate is different from that of the wide side plate. It does not form a crack, but wears or wears the contact surface with the molten iron. Unlike it, the most common failure criterion for wide side plates is the formation of cracks in the area of the casting plane. In the German patent DE 3120978C2, many types of precipitation-hardenable _3__ clothing and paper standards are applicable to China National Standard (CNS) A4 specifications (210 X 297 mm) ----------- · install --- ----- Order --------- (Please read the precautions on the back before filling out this page) 524864 A7 __B7____ V. Description of the invention (/) of the copper alloy and its continuous casting ingot in a fixed position The application of the mold 'uses a variety of different CuNiBe alloys, which also contain other alloy components: niobium (Nb), zirconium (Zr), magnesium (Mg) and / or titanium (Ti). U.S. Patent No. 2,137,281 discloses a copper alloy, CuZrNiBe, which is used in steel strip ingot molds (Twin-Belt Casting), which is characterized by greater hardness and higher thermal conductivity. British patent GB 954796 has published a copper alloy CuBeZrTr for ingot molds, which has better thermal conductivity and higher strength. The US Pat. No. 4,599,120 discloses a copper beryllium alloy containing much less nickel (0.05% to 1%) and cobalt. This conventional alloy is used for cold working and is not suitable for the construction of ingot molds that operate at high temperatures. For trouble-free casting operations, especially for casting thin steel plates at high casting speeds (for example, 6 meters / second or higher), the current mechanical properties of the ingot mold material are not sufficient to generate the high temperatures (especially in In the casting plane area). The present invention is directed to the above background technology, and the object thereof is to provide a copper alloy, which is particularly suitable for manufacturing wide side plates for continuous casting ingot molds of thin steel plates with high casting speed. By using the alloy, early stage can be avoided during the casting operation. The formation of cracks (especially in the area of the casting plane) can reduce the wear of the contact surface in contact with the molten iron, and it can withstand the extremely high thermal and mechanical stress in the casting operation, and can be used for a long time. This is achieved by using a hardenable copper alloy to make wide side plates for continuous casting ingot molds of thin steel plates. It contains beryllium 0.1% to 0.5%, nickel 0.5% to 2.0% (CuNiBe). — __4 _ +, the paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ------------------- Order ------- -(Please read the precautions on the back before filling this page) 524864 B7 V. Description of the invention (")) After hardening, this copper alloy can withstand the high temperature stress in the area of the casting position 'and can avoid formation Cracks' and can maintain a relatively long operating time. [Advantages of the invention] Compared with conventional copper alloys (such as CuCrZr or CuAg), the copper alloy CuNiBe used according to the invention has some advantageous material properties that can cause this successful operating result, such as: much higher tensile Strength, about 770 or about 650N / mm2, and 0.2% tensile limit at 2 (TC and 30 (TC about 500N / mm2).

Therefore, the wide side plate does not need to be plated with nickel. The thermal conductivity of this copper alloy CuNiBe (about 300W / mK) is slightly lower than that of CuAg (about 370W / mK), but Since the thickness of the copper wall is reduced by about 25%, it can be compensated back. Therefore, the material cost of manufacturing can also be saved. The continuous casting ingot mold for thin steel plates used in the present invention for manufacturing high casting speed (for example, 2 to or higher) The copper alloy CuNiBe used in the wide side plates of the alloy contains 0.1% to 0.5% beryllium and 0.5% to 2.0% nickel. They can add 99.5% to copper (the percentage above is the weight ratio). The impurities contained in it must not More than 0.5% (the term "impurity" refers to trace amounts of other metals, such as Fe, Zr, Ag, Cr, Mg, etc.). The present invention can make use of a special copper alloy CuNiBe that is not known in the background to produce high casting speeds ( At least 2 ~ 6m / min or higher) thin copper plate to make the wide side plate of the ingot mold. Due to the long service life (especially the occurrence of cracks in the tank and the level surface area is minimized) and the material And significant improvements in operational properties resulting from reduced manufacturing costs This is the result of special selection of the alloy composition. __7_ Chinese paper standard (CNS) A4 specification (21〇X 297 mm) ------------------- Order --------- ^ 9— (Please read the notes on the back before filling this page)
