Abstract

The invention provides an integrated water tank type crystallizer used for casting 7 series extra super duralumin alloy, relating to a crystallizer. The invention solves the problem that cast ingot produces cracks caused by stress concentration as the existing crystallizer is not even in water-cooling distribution. The cross section contour of the flat through hole is composed of two arc sections and two straight line sections, each arc section is formed by butt joint of two arcs in different diameters; the lower end face of all the side walls of crystallizer tank body is opened with an annular groove, the lower end face of the annular water feeding hole wall body between the annular groove and the flat through hole is opened with a plurality of osculums in uniform distribution, the lower end of each osculum is inclined toward the central axis of the flat through hole; and four clapboards are respectively arranged at the two ends of the annular groove and divide the annular groove into four regions. The crystallizer of the invention adopts four-section design and different diameters of osculums to control water flow, so that cooling of cast ingot is even, temperature is ensured to be consistent with stress field distribution, and cast ingot crack tendency is greatly reduced.

Description

technical field

[0001] The invention relates to an integral water tank type crystallizer, in particular to an integral water tank type crystallizer for casting superhard aluminum alloy. Background technique

[0002] The content of Zn and Cu in the composition content of 7 series superhard aluminum alloy is increased, and the ratio of Zn and Mg is increased, so the alloy has the characteristics of high strength, and Zr is used instead of Cr as the grain refiner, so that the alloy has good quenching At the same time, the content of impurities Fe, Si, Mn is reduced, and the plasticity and fracture toughness of the alloy are improved or increased. Therefore, the alloy has the advantages of high strength, high toughness, and good hardenability. It is used in aerospace materials. Get important applications, suitable for the manufacture of thick-walled parts of large aircraft. However, due to the complex chemical composition and phase composition of this alloy, it shows a great te...
