Abstract

The invention relates to a rare earth-copper alloy glass mold and a preparation method thereof and belongs to the field of glass mold materials. The rare earth-copper alloy glass mold is composed of, by mass, 9-12% of nickel, 7-10% of aluminum, 8-12% of zinc, less than 0.5% of iron, 0.01-0.5% of rare earth and the balance copper. The preparation method includes the steps that brass alloy is prepared from zinc and electrolytic copper; the aluminum, nickel, iron and copper which are weighed are put into a smelting furnace, the brass alloy is added, standing is carried out, impurities float upward, slagging-off is carried out, copper-rare earth intermediate alloy is added, and slagging-off is carried out again; the temperature of rare earth-copper alloy glass mold melt to be poured is increased, and the rare earth-copper alloy glass mold melt to be poured is discharged out of the furnace and poured into a resin sand casting mold; the obtained rare earth-copper alloy glass mold to be annealed is subjected to stress relief annealing and heat preservation and cooled to the room temperature, and the finished rare earth-copper alloy glass mold is obtained. The flowability and toughness of the alloy are improved. The strength and hardness of the alloy are improved, and the abrasion resistance is enhanced. The mechanical properties and impingement corrosion resistance of materials are improved. The toughness and thermal conductivity of the materials are improved.

Description

technical field [0001] The invention belongs to the field of glass mold materials, in particular to a rare-earth copper alloy glass mold and a preparation method thereof. Background technique [0002] Glass mold is the main equipment for the production of glass products. It is frequently in contact with high-temperature glass liquid at 600°C-1100°C, and suffers from oxidation, growth, heat exchange, and thermal fatigue. At the same time, due to frequent mold opening and closing, it is required The contact surface of the mold has excellent wear resistance. Specifically, the surface of the inner cavity of the glass mold is required to have good high temperature resistance, wear resistance, oxidation resistance and corrosion resistance to prolong the service life; the outer circle of the glass mold is required to have excellent heat dissipation performance, and the mold as a whole has good Toughness to ideally accommodate high-speed production needs. [0003] With the rapid d...
