Description
Technical field
The present invention relates to a kind of method for preparing large scale high alloy constituent content magnesium alloy ingot, belong to magnesium alloy material
Material preparation field.
Background technology
Used as structural metallic materials most light at present, magnesium alloy has high, good, rapid heat dissipation of damping performance of specific strength etc.
Lot of advantages, makes it be all with a wide range of applications in many fields such as Aero-Space, automobile, weapons.With
Above-mentioned field continues to develop, and the performance and dimensions to magnesium alloy materials be proposed requirement higher.In reality
In the industrialized production on border, for magnesium alloys such as traditional AZ80, ZK60,600~800mm of Φ are reached in diameter
Large scale ingot blank casting process in, due to inside and outside ingot casting cooldown rate differ greatly, setting time it is long, easily produce
Serious component segregation or generation ingot blank center portion cracking phenomena.And for high-strength temperature-resistant but Plastic phase to relatively low
EW75(Mg-7Gd-5Y-1Nd-0.5Zr)、WE83(Mg-8Y-3Nd-0.5Zr)、WE91
(Mg-9Y-1MM-0.5Zr) magnesium alloy of high rare-earth content such as, its melting, cast temperature are relatively higher, thermal conductivity
Rate is lower, and solidification shrinkage is again very big, and intensity of cooling is small in ingot blank casting process, and setting time is long, component segregation
Seriously；Intensity of cooling is big, and solidification shrinkage is uneven, will produce very big residualinternal stress, easily causes ingot blank
Center portion ftractures, and is as shown in Figure 1 the scene of EW75 magnesium alloy large scales ingot casting casting cracking.
Using semi-continuous casting mode, ingotism, the situation of cracking can be improved, but for diameter greater than 600mm
Magnesium alloy ingot, the especially magnesium alloy ingot of high rare-earth content (be more than 10wt.%), semi-continuous casting mode
Equally it is difficult to solve the problems, such as that ingot casting internal-external temperature difference in process of setting is big, segregation is seriously even ftractureed, also generally deposits
In ingot casting surface cold shut depth, cause follow-up machining amount big, founding link high cost, recovery rate are low.
The content of the invention
It is an object of the invention to provide a kind of method for preparing large scale high alloy constituent content magnesium alloy ingot, the party
Large scale magnesium alloy ingot structural constituent prepared by method is uniform, residual stress is low, tearing tendency is small, high yield rate,
It is particularly suitable for the small lot batch manufacture of the large scale magnesium alloy ingot of current high rare-earth content.
The method that the present invention prepares large scale high alloy constituent content magnesium alloy ingot, mainly comprises the steps：
(1) intermediate alloy ingot with pure magnesium ingot, the pure metal ingot of different-alloy element or they and magnesium is as raw material,
The percentage by weight of the magnesium alloy composition for preparing on demand is got the raw materials ready；
(2) preheating furnace is warmed up to 160~660 DEG C, and melting furnace is warmed up to 500~800 DEG C, and to fusing
