Embodiment Construction
[0020] The present invention will be described in detail below in combination with embodiments.
[0021] The technical solution of this embodiment is: a method for recycling waste strips to smelt iron-based nanocrystalline master alloys, comprising the following steps:
[0022] Step 1, using an induction furnace that has just smelted the iron-based nanocrystalline master alloy and there is remaining molten steel in the furnace, heating, and adding the waste belt to be recovered into the furnace;
[0023] Step 2: After the materials in the furnace are cleared, add a slagging agent, then perform slagging, sampling, and detect its composition by spectrum;
[0024] Step 3: Calculate and weigh the mass of silicon metal, ferroniobium, ferroniobium, and electrolytic copper to be added according to the difference between the measured component content and the target value, and remove slag; adjust the heating power, and add silicon metal, ferroniobium in sequence , ferroboron, electro...

The invention belongs to the technical field of smelting mother alloys and in particular relates to a method for smelting a Fe-based nanocrystalline mother alloy by recovering a scratch tape. The method comprises the steps: 1,, heating by adopting Fe-based nanocrystalline mother alloy which is just smelted and an induction furnace which internally contains residual molten steel, and adding the scratch tape to be recovered into the induction furnace; 2, after completely smelting materials in the induction furnace, adding a slagging constituent, then removing slag, carrying out sampling, and detecting components of a sample by virtue of spectrum; 3, calculating and weighing the masses of metallic silicon, ferrocolumbium, ferroboron and electrolytic copper which are needed to be added according to the a deviation of the connect of the detected components and a target value, removing the slag, regulating a heating power, and sequentially adding the metallic silicon, the ferrocolumbium, the ferroboron and the electrolytic copper; 4, lowering the heating power, and leading argon into the induction furnace; and 5, removing the slag, sampling, tapping, and pouring the molten steel into the mother alloy with a needed shape. With the adoption of the method, the Fe-based nanocrystalline scratch tape can be smelted again to prepare the Fe-based nanocrystalline mother alloy, and the purposes that the resources are saved and the production cost is lowered are reached.
Description
technical field [0001] The invention belongs to the technical field of smelting master alloys, in particular to a method for recycling waste strips to smelt iron-based nanocrystalline master alloys. Background technique [0002] Iron-based nanocrystals are widely used due to their excellent soft magnetic properties. They can be made into magnetic cores for current transformers, precision current transformers, common mode inductors, high-power switching power supplies, inverter power supplies, magnetic amplifiers, filter inductors, Leakage protection switch, high frequency transformer, high frequency converter, high frequency choke coil, etc. Iron-based nanocrystalline alloys are mainly composed of Fe elements, and a small amount of Nb, Cu, Si, and B elements are added to form an alloy. After rapid solidification, an amorphous material is formed. Common iron-based nanocrystalline raw materials are industrial pure iron, metal Silicon, electrolytic copper, ferro-niobium, ferro...
