Novel amorphous master alloy ingot continuous casting system and application method thereof

Abstract

The invention discloses a novel amorphous master alloy ingot continuous casting system which comprises a melting device, a water cooling crystallizer, a traction rod and a traction device, wherein the melting device is arranged in a vacuum chamber, and an exit of the melting device is connected with the water cooling crystallizer; the traction rod is arranged in a flow channel of the amorphous alloy melt; the drainage end of the traction rod is connected with the exit of the melting device, and the traction end of the traction end is connected with the traction device; the flow channel of the amorphous alloy melt is in the vertical direction; a sealing part is arranged on the water cooling crystallizer; the medium in the sealing part directly contacts with the traction rod; and a sealing ring is arranged at the joint between the sealing part and the traction rod. In the system, a continuous casting system taking the output direction of amorphous master alloy ingot as a vertical direction is adopted; and through the structural design, external air can be effectively prevented from entering a melting chamber so as to avoid the defects of the amorphous master alloy ingot such as surface cracks, segregation tumors and throwing oscillation marks generated by oxidation.

Description

technical field [0001] The invention relates to a continuous casting system for metals, in particular to a continuous casting system capable of realizing continuous casting of master alloy ingots of amorphous alloys and a method for using the system. Background technique [0002] Like crystalline alloys, amorphous alloys are multi-component alloy systems, but unlike the periodic arrangement of atoms in crystalline alloys, in amorphous alloys, the arrangement of atoms does not have long-range Characteristic of order, there is a certain degree of short-range order only in the vicinity of individual atoms. Due to the special microstructure characteristics of amorphous alloys, amorphous alloys do not have defects such as grain boundaries, dislocations and twins of traditional crystal materials, so they have many excellent properties, such as unique electromagnetic properties, mechanical properties, high strength and hardness and high corrosion resistance. So far, the study of ...

AI Technical Summary

Problems solved by technology

Although the above scheme can avoid oxidation on the surface of the amorphous master alloy ingot, the system requires two vacuum chambers to be used, and in terms of vacuum control operation, its controllability is poor, and the cost and operating cost are high, so it is not suitable for popularization.
