The invention discloses an aluminum alloy casting hot crack simulation device and a hot crack prediction method.The aluminum alloy casting hot crack simulation device comprises a casting mold used for conducting simulation casting on aluminum alloy, the casting mold is divided into a front side mold and a rear side mold which are symmetrically arranged front and back, the front side mold comprises a first semicircular thick pipe, and a first semicircular cap pipe is arranged on the upper side of the first semicircular thick pipe; the front side mold comprises a first semicircular thick pipe, first semicircular thin pipes are symmetrically arranged on the two sides of the first semicircular thick pipe, the rear side mold comprises a second semicircular thick pipe, a second semicircular cap pipe is arranged on the upper side of the second semicircular thick pipe, second semicircular thin pipes are symmetrically arranged on the two sides of the second semicircular thick pipe, and the first semicircular thick pipe and the second semicircular thick pipe are arranged in a front-back corresponding mode. The device provided by the invention is easy to operate, can observe the generation of various hot cracks, and has the advantages of being more comprehensive in prediction position, capable of performing semi-quantitative prediction and the like compared with a previous hot crack prediction method.
Description
technical field [0001] The invention relates to the technical field of casting, in particular to an aluminum alloy casting hot crack simulation device and a hot crack prediction method. Background technique [0002] Aluminum alloys are widely used in aerospace, automobile manufacturing and other fields. Aluminum alloy products usually need to go through processes such as casting, deformation processing, and heat treatment. Common casting methods include die casting, direct cooling casting, etc. In the casting process, various defects often occur, such as: hot cracking, cold cracking, warping, etc. Among them, hot cracking is the most common and the most serious casting defect. In order to study the formation mechanism of hot cracking and predict it, a large number of scholars have built hot cracking prediction models, but most of them are for one-dimensional / two-dimensional models, and there is still a certain gap with the actual situation.
