Aluminum alloy ingot casting area water cooling device

Abstract

The invention provides a water cooling device for aluminium alloy ingot area. The water cooling device mainly comprises a bracket, a main clamping plate, an auxiliary clamping plate, a connecting rod, a cylinder and a wiper plate, a plurality of positioning holes or guiding grooves are arranged in the height direction of the bracket, a support rod is inserted in the positioning hole or the guiding groove, and the support rod is sleeved with two main clamping plates, and the cylinder is arranged between the two main clamping plates, each main clamping plate is connected with the auxiliary clamping plate through the connecting rod, and inner walls of each clamping plate and auxiliary clamping plate are provided with a wiper plate respectively. The cylinder retracts to drive the main clamping plate to retract and the two auxiliary clamping plates retract under the drive of the connecting rod so that the wiper plates can realize automatic clamping or loosening ingots. The water cooling device is safe, convenient, can adjust the effective cooling length of regional cooling flexibly, is easy to realize automatic control, and better meets the casting requirement of hard aluminium alloy casting.

Description

technical field [0001] The invention relates to a water cooling device for an ingot in a hard aluminum alloy semi-continuous casting process, and belongs to the technical field of aluminum alloy semi-continuous casting. Background technique [0002] The traditional direct cooling semi-continuous casting (DC casting) method is the main way to prepare hard aluminum alloy ingots in industry. In the semi-continuous casting process, due to the inhomogeneous cooling of the core and edge of the ingot, the internal stress generated by the solidification and shrinkage of the ingot is large. When the internal stress exceeds the strength limit of the material, the ingot will crack. In particular, hard aluminum alloys represented by 2XXX and 7XXX have high content of alloying elements, large number of eutectic phases with low melting point at grain boundaries, wide solidification temperature range during solidification, small plastic zone and brittle zone Larger, the ability of the ing...
