Abstract
The invention discloses a non-ferrous metal glass mold and a preparation process thereof. The non-ferrous metal glass mold comprises the following components in percentage by weight: 0.17-2.4% of cobalt, 0.17-0.21% of silicon, 0.4-1.7% of nickel and the balance of raw material copper and inevitable trace impurities. The preparation process comprises the following steps of: manufacturing a casting mold, utilizing a melting furnace to melt the raw material copper, forming a copper solution, then adding the silicon and the nickel into the copper solution, further adding the cobalt into the copper solution obtained in S20, and stirring to melt the cobalt into the copper solution so as to obtain a liquid-state cobalt-copper alloy. According to the preparation process disclosed by the invention, a cobalt-copper alloy cast is taken as a production workpiece, and has not only good processing performance and wear resistance, but also high efficiency and heat resistance; and furthermore, because the consumption of raw materials and energy is reduced, the pollution during the production process is reduced. As the production efficiency is improved, replacement and maintenance of the mold during the production process are reduced.
Description
Technical field
The present invention relates to a kind of alloy production technique, especially non-ferrous metal glass mold and preparation technology thereof.
Background technology
Along with improving constantly of standard of living, the human consumer constantly promotes the demand of daily glass product both at home and abroad, class and specification of quality to product also improve constantly, maximum contention adversary's plastics of adding glass itself are the derived product that belongs to oil, its proper constituent is unfavorable to health, many countries put into effect the policy of " plastic limit ", this has also brought new development and challenge to the domestic glass packaging industry, source as domestic glass packaging industry industrial chain, glass mold will be to more accurate under the driving of large situation in industry, the high-order level development that the life-span is longer.In addition improving constantly along with people's living standard, people are more and more higher to the requirement of high-end glasswork, but China's glass mold manufacture level is compared in addition larger gap with the world, for example a goblet is sold several units, dozens of yuan for domestic, abroad top grade then can buy units up to a hundred, thousands of units, therefore to the glass mold transition of high-end precision, improving international competitiveness is the main direction of China's glass mold development.
Cobalt-copper alloy has good thermal conducting performance and physicals, and has acid resistance.Easily satisfy work-ing life and the fast-developing working condition of system bottle.Cobalt dissolves in the diluted acid, is passivated because generating layer oxide film in nitrosonitric acid.Cobalt is the glossiness Steel Grey metal of tool, 1493 ℃ of fusing points, proportion 8.9, harder and crisp, cobalt is ferromagnetic, similar with iron and nickel aspect hardness, tensile strength, machining property, thermodynamic property, electrochemical behavior, have good processing characteristics and anti-wear-resisting, resistance toheat, so use the cobalt-copper alloy foundry goods to become a kind of trend of glass industry.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the applicant has researched and developed non-ferrous metal glass mold and preparation technology thereof through long-term practical exploration.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the present invention is: non-ferrous metal glass mold and preparation technology thereof, described non-ferrous metal glass mold components by weight is as follows: 0.17～2.4% cobalt, 0.17～0.21% silicon, 0.4～1.7% nickel, surplus are raw copper and inevitable trace impurity.
Described preparation technology may further comprise the steps:
S10 makes casting die;
S20 utilizes smelting furnace melting raw copper, behind the formation copper liquid silicon and nickel is added in the copper liquid, and the rear adding insulating covering agent of skimming stirs, and makes silicon and nickel incorporate copper liquid;
S30 adds cobalt in the copper liquid that S20 obtains, and stirs, and cobalt is circulated in the copper liquid, obtains liquid cobalt-copper alloy;
S40, the cobalt-copper alloy of the liquid state that S30 is obtained injects casting die, then temperature is adjusted into 910～920 ℃, forms solid-state cobalt-copper alloy foundry goods;
S50 keeps the solid-state cobalt-copper alloy foundry goods that obtains among the S40 1.5 hours under 910～920 ℃ of temperature environments, in the cold water of then quenching fast, forms required foundry goods.
Further, in the described S20 step, the temperature of smelting furnace rises to 1200～1250 ℃ of melting raw copper.
Again further, in the described S30 step, copper liquid temperature is adjusted to 1100～1200 ℃, then adds cobalt.
Further, the smelting furnace in the described S30 step is vacuum induction furnace.
Beneficial effect: the present invention compared with prior art, its beneficial effect is:
1, the present invention as production work, not only has good processing characteristics and anti-wear with the cobalt-copper alloy foundry goods, and has the performance of efficient heat-resisting;
2, the present invention has reduced the pollution in the production process owing to reduced starting material and energy consumption.Because production efficiency improves, and reduced die change maintenance in the production process.
