鋁線纜材用Al-Ti-B-M中間合金制備工藝的研究
[Abstract]:In recent years, with the rapid development of aluminum and aluminum alloy industry, aluminum products are more and more widely used in people's daily life. In the context of building a resource-saving society, people attach importance to the recycling and reuse of aluminum. Because of the high content of impurity elements (Fe,Si, etc.), the recycled aluminum has poor performance and less use. It is found that the fine and uniform microstructure can be obtained by adding master alloy refiner to aluminum and alloys, and the mechanical properties, mechanical properties and conductive properties of the products can be improved, and the quality of the products can be improved. The most widely used industrial method is to add filamentous master alloy refiner in continuous casting and rolling production line. Aluminum is widely used in cable factories because of its advantages of light weight, high strength and good conductivity. It is a good choice to refine the regenerated aluminum and use it as cable. Grain refinement can increase the strength of aluminum and improve the properties of aluminum, and the addition of trace elements has a great effect on the conductivity of aluminum alloy. In this paper, the effects of Al-5Ti-1B-M (M=La/Ce/Y/Ca) on the microstructure, mechanical properties and electrical conductivity of recycled aluminum Al-Fe-Si were studied. The purpose of this study was to find a new and efficient intermediate alloy refiner for cable materials to improve the properties of recycled aluminum. So that it can be used as industrial cable raw materials. In this paper, the effects of different trace element refiners on the properties of regenerated aluminum Al-Fe-Si alloy were studied by changing the experimental raw materials, operation technology, heat treatment process and so on. The main conclusions are as follows: (1) different trace elements have little effect on the microstructure of master alloy refiner, and the microstructure and properties of Al-5Ti-1B-La master alloy refiner are better. The tensile properties, hardness and electrical conductivity of regenerated aluminum have been changed, and the properties of regenerated aluminum with Al-5Ti-1B-La master alloy refiner have been improved. The effect of the master alloy refiner prepared by industrial potassium fluoroborate and potassium fluorotitanate is relatively good. The cost of preparation was greatly reduced. 4. The properties of regenerated aluminum were not changed obviously after the optimization of heat treatment process.
