本文介绍了锰铜高阻尼合金中各元素的基本作用以及合金的熔持特性。为保证合金铸件具有优良的冶金质量,其熔炼工艺原则是:合金应在感应电炉的碱性坩埚中熔炼;金属原材料中的电解锰和电解铜必须进行予除气处理;为防止合金液吸气和氧化,应采用专用覆盖剂;为降低合金液中气体含量,应进行除气处理;采用铝、镁等脱氧剂进行高温脱氧精炼,排除夹杂物,起净化作用;选择并控制合金的熔炼温度和浇注温度。
This paper introduces the basic role of each element in manganese-copper high-damping alloy and the melting characteristics of the alloy. In order to ensure the excellent metallurgical quality of the alloy castings, the principle of the smelting process is as follows: the alloy should be melted in the alkaline crucible of the induction furnace; the electrolytic manganese and the electrolytic copper in the metal raw material must be degassed; And oxidation, should be used special covering agent; In order to reduce the gas content of the alloy liquid, should be degassing treatment; Deoxidizer such as aluminum and magnesium deoxidation at high temperature, excluding inclusions, play the role of purification; Select and control the alloy melting temperature And pouring temperature.
