Water baffle plate device suitable for aluminum alloy circular ingot half-continuous casting

Abstract

The invention provides a water baffle plate device suitable for aluminum alloy circular ingot half-continuous casting, which comprises a clamping mechanism, a clamping ring and heat resistant rubber. A pair of handles is arranged at the rear end of the clamping mechanism, and a pair of clamping paws is arranged at the front end of the clamping mechanism; a semicircular clamping ring is arranged on each clamping paw; an annular groove is formed on the inner wall of each semicircular clamping ring; half annular heat resistant rubber is embedded into the annular groove of each semicircular clamping ring; the two half annular heat resistant rubbers are clamped opposite to form an integral circular loop; and a steel rope is chained on each semicircular clamping ring. When a water baffle plate is needed, the heat resistant rubber is jointed to the surface of the cast ingot by clamping the handle via a spring to baffle the dropping cooling water, and then the cooling strength of the cast ingot on the lower part of the water baffle plate is weakened; meanwhile, high-temperature melting body in a liquid cave on the upper part of the cast ingot reheats the cast ingot so as to achieve self-tempering effect of the cast ingot and effectively reduce the inner casting stress; and the casting requirement of the aluminum alloy can be better met.

Description

technical field [0001] The invention relates to a water baffle device suitable for semi-continuous casting of aluminum alloy round ingots, and belongs to the technical field of semi-continuous casting of aluminum alloys. Background technique [0002] When the traditional direct cooling semi-continuous casting process is used to prepare aluminum alloy round ingots, due to the uneven cooling of the center and edge of the ingot, the internal stress of the ingot is large, and casting problems such as cracking are prone to occur. Especially for the 2××× and 7××× series hard aluminum alloys with high alloying degree, it is easy to form a large number of eutectic phases with low melting point at the grain boundary, and the plastic zone of the ingot is small and the brittle zone is relatively small during the solidification process. Large, the ability of the ingot to resist crack formation is low, coupled with the uneven cooling of the center and edge of the ingot, the internal stre...
