Embodiment 1

[0032] The tundish of this embodiment includes: a tundish body 1, which is formed with an alloy liquid container 6 for containing the molten alloy liquid 2; a liquid leakage hole 5 is provided on the bottom surface of the tundish body 1, and is used for setting a leakage hole 5; eye device. The tundish body 1 is made of graphite clay; the protective coating 4 is arranged on the inner wall of the tundish body 1 (the inner wall includes a side wall and a bottom wall), and is used to prevent the molten alloy liquid 2 from contacting the inner wall of the tundish body 1. Chemical reaction and erosion occur, and the protective coating 4 is a magnesium oxide coating, and the thickness of the coating is about 6mm. The tundish body 1 also includes a leaking device (not shown in the figure) arranged at the leak hole 5, so that the alloy liquid in the tundish body falls at a prescribed speed, and the leaking device can be purchased from the market as required, and its The flow rate of ...

Abstract

The invention discloses a tundish for preparing iron-nickel soft magnetic alloy powder through water atomization and a manufacturing method of the tundish. The tundish comprises a tundish body and a protection coating. The tundish body is used for containing molten alloy liquid. The protection coating is arranged on the inner wall of the tundish body and used for preventing the tundish body from chemically reacting with the alloy liquid. Magnesium oxide serves as the protection coating of the tundish, the inner wall of the leakage tundish is coated with magnesium oxide coating, direct contact between molten steel and a graphite clay material is avoided, molten steel foam is reduced and eliminated, and the atomization production process is stable and smooth; and meanwhile, the service life of the tundish can be prolonged, the service life of the tundish can be prolonged to 10 heats from previous 1 to 2 heats, and therefore the production cost is greatly reduced.

Description

technical field [0001] The invention relates to an atomization tundish, in particular to a tundish for preparing iron-nickel soft magnetic alloy powder by water atomization and a manufacturing method thereof, belonging to the field of powder metallurgy. Background technique [0002] Iron-nickel alloy powder is a common catalyst material for diamond synthesis, which is usually prepared by smelting and atomization. During the preparation process, the alloy is melted first, and then the molten steel is poured into a leaky ladle (ie, a tundish). Usually the leak bag is made of graphite clay material, see figure 1 , including only the tundish body 1 made of graphite clay, when the high-temperature molten steel 2 contacts the inner wall of the leaky ladle, a large number of air bubbles 3 will be generated to form foamed steel, which hinders the flow of molten steel and affects the process. In this case, the service life of the leaking bag is drastically reduced. [0003] During...
