This invention discloses a composite mold for casting copper smelting anode plates. The mold includes a composite mold body with a segmented structure, comprising a lower copper mold body and an upper cast steel mold body. The copper mold body and the cast steel mold body are fixedly connected by a dovetail groove inlay structure. The copper mold body is configured as a permanent section, while the cast steel mold body is configured as a replaceable section. The ears of the cast steel mold body are movable and detachably connected to the side frame of the cast steel mold body by bolts. This invention, by employing a copper-steel composite structure, fully utilizes the excellent thermal conductivity of copper and the good structural strength of steel, effectively solving the problems of surface cracking, frame cracking, and ear deformation common in existing molds. This significantly extends the service life of the mold, reduces maintenance costs, and improves the casting quality of the anode plate.

This invention discloses a high-strength, lightweight aluminum-based medium-entropy alloy and its preparation method, relating to the technical field of lightweight medium-entropy alloy materials. The raw material composition of this aluminum-based medium-entropy alloy, expressed as Al in atomic percentage, can be... a Ti b Cr c M d The alloy comprises 45-65% Al, 10-30% Ti, 15-30% Cr, and 5-10% M, where M is one or more of Sc, V, and Mn, and a+b+c+d = 100. The specific preparation method is as follows: Pretreated raw materials are weighed according to the proportions and placed in a vacuum arc melting furnace or vacuum induction melting furnace. The alloy is melted under high-purity argon protection and held at a constant temperature to ensure uniform composition. The molten alloy is then poured into a preheated cast iron mold or water-cooled copper mold and allowed to cool naturally to room temperature to obtain an aluminum-based medium-entropy alloy ingot. The aluminum-based medium-entropy alloy prepared by this invention possesses both low density and high strength. Its as-cast microstructure is predominantly a solid solution phase, exhibiting excellent strength-plasticity matching. This allows for the fabrication of lightweight, high-performance cast structural parts without the need for complex thermomechanical processing.

The application discloses a method for preparing Sc-Er synergistically reinforced Al-Zn-Mg-Cu alloy by electromagnetic directional solidification, and belongs to the technical field of aluminum alloys. The alloy composition comprises Zn, Mg, Cu, Sc, Er, the balance of Al and inevitable impurities. The vacuum induction melting furnace is used for electromagnetic directional solidification, under the synergistic action of an alternating electromagnetic field and a water-cooled copper mold, the coupling of melt electromagnetic stirring and directional heat flow is realized, the grain is significantly refined, and the composition segregation is inhibited. After subsequent homogenization, hot working and aging treatment, the Sc-Er synergistic effect is used to precipitate high-density, heat-stable L12 type Al3(Sc, Er) nanometer dispersed phase in the matrix. The phase and the η' phase precipitated during aging form a double-peak strengthening system, effectively pinning the grain boundary, inhibiting recrystallization and phase coarsening. The application solves the problems of low toughness and poor heat resistance of high-Zn alloy, and realizes the synergistic improvement of strength, toughness and heat stability.
