The invention relates to the technical field of metal impregnation, in particular to a vacuumizing metal impregnation method which comprises the following steps: S1, putting metal into a graphite crucible, closing a metal liquid inflow pipe and a metal liquid return pipe, turning on a power supply of a heating element, and melting the metal; s2, putting a graphite product to be impregnated into a graphite frame; then the graphite frame is hung on a placing table, the tank body is sealed and vacuumized, and infrared radiation is adopted for heating; s3, opening the molten metal inflow pipe, and meanwhile, introducing N2 gas into the molten metal surface through a pressurization system for pressurization; s4, after immersion, closing the molten metal inflow pipe, restoring to atmospheric pressure, opening the molten metal inflow pipe, and enabling the molten metal to flow back to the graphite crucible; s5, the molten metal inflow pipe is closed, a proper cooling curve is selected according to the performance index requirement condition of a final product, the graphite product is taken out of a frame after being cooled, and the impregnated graphite product is taken out and put into filler to be prevented from being oxidized; according to the invention, metal impregnation can be well carried out.
本发明涉及金属浸渍技术领域，涉及一种抽真空金属浸渍方法，并包括以下步骤：S1、将金属放入石墨坩埚中，关闭金属液流入管和金属液回流管，打开加热元件的电源，熔化金属；S2、把要浸渍的石墨制品放入石墨框中；然后将石墨框吊入到放置台上，把罐体密封，抽真空，并采用红外辐射加热；S3、打开金属液流入管，同时通过加压系统向金属液面通入N2气加压；S4、浸好后，关闭金属液流入管，恢复到大气压，打开金属液流入管，让金属液流回石墨坩埚；S5、关闭金属液流入管，根据最终产品的性能指标要求情况，选择合适的降温曲线，待冷却后出框，把浸渍好的石墨制品取出，放入填料中防止氧化；本发明能较佳地进行金属浸渍。
