Embodiment

[0040] Embodiment: adopt 300kg vacuum induction melting furnace to smelt 200 kilograms of manganese-copper alloy. Including the following steps:

[0041] S 1 1. Select 150 kg of electrolytic manganese flakes, 40 kg of electrolytic copper blocks, 6 kg of electrolytic nickel blocks, 4 kg of electrolytic aluminum blocks, and 2 kg of slagging agent. First add the electrolytic manganese sheet into the crucible, then place the electrolytic pure copper and pure nickel raw materials on the electrolytic manganese sheet, and then place the electrolytic aluminum block and slagging agent respectively in the silo;

[0042] S 2 1. Close the vacuum chamber, and when the vacuum is below 20Pa, start the heating power supply, increase the power supply step by step to 180kW to preheat the metal raw materials; at the same time, continue to pump to keep the vacuum below 10Pa.

[0043] S 3 1. After observing the red heat of the metal raw materials in the furnace, stop vacuuming, fill the vacuum...

Abstract

The invention discloses a vacuum induction smelting method for a manganese-copper damping alloy. The vacuum induction smelting method comprises the steps that a metal raw material and an alloy material are selected, cloth furnace loading is conducted, vacuumizing is conducted, imposing electric for heating is conducted, the argon is filled after glowing red of the metal raw material in s furnace,continuous heating is conducted until melting down is achieved, still standing and refining are conducted, slag making is conducted, slag skimming is conducted, the alloy material is added, and temperature adjusting and pouring are conducted. The vacuum induction smelting method has the advantages that the slag making procedure is introduced, a large number of metal oxide inclusion produced in thesmelting process of the manganese-copper alloy can be effectively removed, the alloy purity degree is increased, the forging performance of the alloy and the alloy quality are improved, a shrinkage compensation section adopts a reciprocating pouring shrinkage compensation process, the hole shrinkage and shrinkage porosity of an ingot can be effectively reduced, the riser forging performance is improved, the ingot using rate is increased, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of smelting and preparation of special alloys, in particular to a vacuum induction smelting method for a manganin-copper damping alloy. Background technique [0002] With the rapid advancement of science and technology, people's requirements for the stability and precision of mechanical systems are increasing day by day. The harm caused by mechanical vibration, especially in aerospace, precision machining, precision measurement and other fields, the harm caused by micro-vibration interference is becoming increasingly apparent. Therefore, the high damping alloy with integrated structure and function is used to process and prepare the support member of the vibration source, so as to achieve the effect of vibration reduction and vibration isolation, so as to improve the accuracy, stability and life of the overall system, which has been widely valued by the society. [0003] Compared with other vibration dampin...
