The invention relates to a cast ingot solidification tail end electromagnetic stirring device applied to the metallurgical industry, in particular to a telescopic cast ingot solidification tail end electromagnetic stirring device applied to a semi-continuous aluminium alloy casting process. The device is fixed on the ground outside a casting well, and comprises two parallel groups of electromagnetic stirring device bodies, pneumatic devices and worm and worm gear lifting devices, which are symmetrical about the longitudinal cross section of the cast ingot solidification tail end; one end of an electromagnetic stirrer positioned in each electromagnetic stirring device body is movably connected with an air cylinder positioned in each pneumatic device; each electromagnetic stirring device body and each pneumatic device are arranged on a bearing steel plate; positioning holes are formed in each bearing steel plate; each worm and worm gear lifting device is fixedly arranged on a base, and one end of each worm and worm gear lifting device is movably connected with each bearing steel plate. According to the invention, the structure is simple, the operation is convenient, the application range is wide, high safety and stability are achieved, the production efficiency is high, the quality of an aluminium alloy cast ingot is improved, and the yield of the cast ingot is guaranteed.
Description
technical field [0001] The invention relates to an electromagnetic stirring device at the end of casting slab solidification applied in the metallurgical industry, in particular to a telescopic electromagnetic stirring device at the end of solidification of ingot. Background technique [0002] The production process of semi-continuous casting aluminum alloy ingots is to continuously pour molten aluminum into the crystallizer at a certain casting speed. The mold is equipped with a cooling water jacket, and the crystallized ingots are continuously pulled out vertically at a certain speed. , The ingot from the crystallizer is cooled and solidified and then formed. [0003] In general, there is a meniscus-shaped liquid cavity with a depth of 500mm-1000mm inside the solidification end of the aluminum alloy ingot coming out of the crystallizer, and there is a large temperature difference between the inside and outside of the ingot, which will easily lead to the internal structure ...
