Abstract
The invention provides a process for producing high-performance manganese-aluminum alloy. The process comprises: taking manganese and aluminum as raw materials, grinding the raw materials, mixing themanganese well with the aluminum in a weight ratio of 15 to 85 at a temperature between 10 and 20 DEG C and putting the mixture into a vacuum synthesis furnace; discharging air in the synthesis furnace to form high pressure in the furnace; using electrodes to heat the synthesis furnace at a heating speed of 3 to 4 DEG C/min; maintain the temperature range in the synthesis furnace in a period of time to synthesize products; and finally adopting cooling water (room temperature) in a circulating water tank to cool the synthesis furnace and sending a compound out of the furnace after the furnace is cooled to a certain temperature. The method is little pollution of process flow and high performance of products.
Description
One, technical field:
The present invention relates to a kind of manufacturing process of alloy, especially relate to a kind of production technique of high-performance mangal.
Two, background technology:
Mangal claims that again the manganese ferroaluminium is a kind of new high-tech material, and in STEELMAKING PRODUCTION, it promptly is strong reductor, it is again additive, also can use, in steel and alloy, add the mangal of minute quantity, can reach the purpose that purifies steel and alloying as master alloy.Therefore it is widely used in civilian industry, particularly is applied to high-tech areas such as space flight and aviation.At present the commercial application of mangal manufacturing technology has only five countries in the whole world, does not domesticly form industrialization as yet.China is the raw material supply base of global mangal maximum, to but dependence on import of the demand of mangal.The output of the annual electrolytic manganese of China reaches nearly 400,000 tons, and area, the western Hunan only the electrolytic manganese annual production just account for national output more than 60%, area, western Hunan Mineral resources advantage is very obvious, rely on its other resources superiority condition, use this technology major and immediate significance to be arranged advancing regional new industrialization process.
The production technique of mangal mainly is to claim alloy to convert method again with intermediate frequency furnace remelting fusion process at present, promptly convert and produce with medium high carbon ferromanganese, waste and old aluminum shot, the remelting by a certain percentage of waste and old steel, this kind production is not relying on manual operation to finish under the closed state, it is produced and stirs and must be undertaken by the dry wooden stick of artificial usefulness, therefore operator's danger of being easy to be subjected to the injury of hyperthermia radiation and electric shock being arranged, the easy efflorescence of the product that this kind production technique is produced, produced a large amount of dust and waste water in its production process, environment has been caused pollution.
Three, summary of the invention
The object of the present invention is to provide a kind of production technique of high-performance mangal, it compared with prior art, its production process is safe and efficient, can solve waste gas and discharge of wastewater problem in the mangal production process, make and be in closed state in the whole process of production, no dust and discharge of wastewater.
In order to reach the foregoing invention purpose, the present invention adopts following steps:
(1), crushing metal manganese and metallic aluminium;
(2), under 10 ~ 20 ℃ condition with manganese metal and metallic aluminium in by weight 15: 85 ratio thorough mixing, and in the vacuum synthetic furnace of packing into;
(3), get rid of the air in the synthetic furnace, making the vacuum tightness in the synthetic furnace is 10 ~ 30PA;
(4), adopt electrode synthetic furnace to be heated with the speed of 3 ~ 4 ℃/min;
(5), with material synthetic 6 ~ 8hr in 600 ~ 800 ℃ scope;
(6), behind the end of synthesis, adopt the water coolant in the circulating water pool that synthetic furnace is cooled off, when being cooled to 100 ~ 150 ℃ material is come out of the stove.
Manganese is manganese powder, and purity is 99.7%, and aluminium is metallic aluminium powder, and purity is 99.9%.
The size range of pulverizing the back manganese metal is 80 orders ~ 100 orders, and the size range of metallic aluminium is 60 orders ~ 80 orders.
Advantage of the present invention is product hardness and the wear resisting property height of producing; Whole process of production is closed production, all is to carry out in the infiltration stove, does not therefore have dust to fly out; Add thermal recovery heated by electrodes device and heat, need not to carry out the technology heating and just can finish heat-processed, so production process does not have the waste gas generation with bunker coal or oil fuel; The temperature control process adopts the recirculated water temperature control, uses water source from the beginning, the production process non-wastewater discharge.
Four, description of drawings
Be expressed as the technological process of production figure of high-performance mangal.
Five, embodiment
With 85g purity is that 99.7% manganese metal and 15g purity are that 99.9% metallic aluminium is pulverized, and the size range that makes manganese is 80 orders ~ 100 orders, and the size range of aluminium is 60 orders ~ 80 orders; Under 10 ~ 20 ℃ condition, be that 85% manganese metal and content are the thorough mixing of 15% aluminium with content, and in the vacuum synthetic furnace of packing into; Extract the air in the synthetic furnace, make the vacuum tightness in the synthetic furnace reach 10 ~ 30PA; Adopt electrode synthetic furnace to be heated with the speed of 3 ~ 4 ℃/min; Mixture in 600 ~ 800 ℃ of scopes, is synthesized 6 ~ 8hr; Adopt the water coolant (normal temperature) in the circulating water pool that synthetic furnace is cooled off, remove stove after cooling the temperature to 100 ~ 150 ℃, both product of the present invention.
