A kind of aluminum titanium boron production process

Abstract

The invention discloses a production process of aluminum, titanium and boron. Firstly, raw materials are put into a reduction table bag for reduction reaction, and a stirrer is used for stirring according to the needs of the reduction reaction; after the reduction reaction is completed, it is transferred into a frequency conversion furnace for alloy chemical operation; finally, the alloy aluminum water enters the continuous casting and rolling process through the crucible to obtain the finished product of aluminum titanium boron. The force is proportional to the specific power density of the electric furnace and inversely proportional to the square root of the operating frequency. The invention separates the reduction reaction from the alloy operation, avoids the uncontrollable drastic temperature change due to the generation of a large amount of heat in the reduction reaction, reduces the occupation time of the crucible, and improves the production capacity; changes the aluminum water out of the crucible to the bottom out method , The electromagnetic stirring generated by the frequency conversion furnace can be used to prevent the precipitation of titanium elements, so that there is no need to add a new holding furnace and electromagnetic stirrer, which reduces the investment in equipment.

Description

technical field [0001] The invention belongs to the technical field of metallurgical production, and relates to an aluminum alloy production method, in particular to an aluminum titanium boron production process. Background technique [0002] Aluminum-titanium-boron alloy is the most commonly used grain refiner for aluminum and aluminum alloys. It is added to aluminum and aluminum alloys to refine the base material. It is widely used in the global aluminum casting and rolling industry. Years of research have found that: TiB2 and TiAl3 are the main refining substances in AlTiB wire, and the content of Ti and B in the alloy and the distribution and morphology of the two phases of TiB2 and TiAl3 in AlTiB alloy And the size has a direct impact on the grain refinement ability of AlTiB alloy used as grain refiner. Therefore, in the production process of aluminum titanium boron, how to ensure the accuracy of the composition and control the distribution, morphology and size of the ...

Problems solved by technology

However, due to the working characteristics of the industrial frequency furnace and the large amount of heat generated during the reduction reaction, it is impossible to effectively control the stirring force and temperature of the aluminum water during the reduction reaction and alloying operations; therefore, it is impossible to produce high-quality aluminum and titanium. Boron alloy products; at the same time, in the traditional process, the alloy aluminum water from the crucible adopts the upward method, and due to the strong precipitation of titanium in the aluminum-titanium-boron alloy, it is necessary to increase the holding furnace and electromagnetic stirrer, so that the input Increased costs
