Abstract
The utility model relates to the technical field of continuous steel casting, in particular to a copper plate for a crystallizer of a continuous casting machine. The copper plate for the crystallizer is rectangular and made from an aluminum oxide dispersion strengthened copper material, and has the length of 50 to 3,000mm, the width of 50 to 1,000mm and the thickness of 10 to 200mm. The copper plate for the crystallizer has high thermal stability, and can maintain original physical and mechanical properties even at temperature approximate to the melting point of copper. The copper has higher electrical conductivity, a higher heat-conducting property, higher hardness, stronger strength and the like compared with chromium zirconium copper, so that the service life of the copper plate for the crystallizer is prolonged.
Description
Technical field
The utility model relates to the continuous casting steel machine technical field, relates in particular to a kind of conticaster and uses copper plate of crystallizer.
Background technology
Crystallizer is the core component of conticaster, copper plate of crystallizer as continuous casting steel machine from liquid molten steel to the important conducting-heat elements that is frozen into solid-state base shell, its quality quality directly has influence on indexs such as slab surface quality, conticaster pulling rate.The steel flow of fusion crystallizes into base, and is pulled out from crystallizer by dummy bar through copper plate of crystallizer under the effect of extraneous cooling water.Often throwing can make the copper plate of crystallizer serious wear, changes frequently, not only reduces production efficiency, and consumes a large amount of crystallizers.On present high operating rate, high casting rate conticaster, high temperature wear, fire check, thermal deformation have become the main cause that copper plate of crystallizer is changed.Require it to have good thermal conductivity, good wearability, higher recrystallization temperature, favorable rigidity and processability to continuous casting crystallizer copper plate.Be to improve the service life of copper plate of crystallizer, person skilled both domestic and external has been launched long-term, research in depth to the copper coin material, and the copper plate of crystallizer material that extensively adopts at present is red copper, silver-bearing copper, chromium zirconium copper etc.Though can't fully satisfy continuous casting steel machine production requirement to copper plate of crystallizer progressively improving the service life of copper plate of crystallizer.
The utility model content
The technical problem that the utility model will solve is to provide a kind of novel conticaster to use copper plate of crystallizer.Physical life with further raising copper plate of crystallizer.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of conticaster is used copper plate of crystallizer, it is characterized in that, said copper plate of crystallizer is rectangular, and it is processed by the aluminum oxide dispersion copper product.
The length of said copper plate of crystallizer is 50～3000mm, and width is 50～1000mm, and thickness is 10mm～200mm.
Said aluminum oxide dispersion Cu crystallizer copper coin, A1 in its chemical composition
20
3Content is 0.03-0.8%.All the other are Cu.
The beneficial effect of the utility model is: the utility model adopts the aluminum oxide dispersion copper product to process; The advantage of aluminum oxide dispersion copper product is existing than red copper and high intensity and the softening temperature of chromium zirconium copper; The heat-conductivity conducting performance that red copper about 85% is arranged again; Its softening temperature can reach 900 ℃, and the softening temperature of red copper has only 250 ℃, and the softening temperature of chromium zirconium copper is 500 ℃.High softening temperature can stop the crystallization again of material, prevents grain growth, improves the ability of thermal fatigue resistance.The heat endurance of aluminum oxide dispersion copper is fabulous, even under near the temperature of copper fusing point, still can keep original physical properties.Therefore the copper plate of crystallizer of the utility model all has superior performance on aspects such as conduction, heat conduction and hardness and intensity, and the service life of therefore having improved copper plate of crystallizer.
Description of drawings
Fig. 1 is the sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1, a kind of conticaster is used copper plate of crystallizer, it is characterized in that, said copper plate of crystallizer is rectangular, and it is processed by the aluminum oxide dispersion copper product.
The length of said copper plate of crystallizer is 50～3000mm, and width is 50～1000mm, and thickness is 10mm～200mm.
Said aluminum oxide dispersion copper coin can make as follows: according to A1
20
3Content 0.61%, all the other feed intake for Cu, and earlier with the albronze fusing, the Cu-Al alloyed powder is processed in atomizing then, with Cu
20 is blended in the airtight container and heats the oxidized generation of solute element Al A1
20
3After obtaining the crystallizer copper blanks, be heated 870 ℃ and carry out forge hot to regulation processing dimension, be machined into finished size at last.The testing product performance is following:
Electrical conductivity: 84.1%IACS; Tensile strength: 487N/mm
2Percentage elongation: 14.8%; Hardness (HB): 153
Adopt the aluminum oxide dispersion carbon/carbon-copper composite material,, can replace domestic red copper or the chromium zirconium copper product copper plate of crystallizer that generally adopts, improved copper plate of crystallizer physical property and mechanical performance through the copper plate of crystallizer that thermal forging technology is produced.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
