Quick coagulation furnace for producing permanent magnet materials

Abstract

The invention discloses a quick coagulation furnace for producing permanent magnet materials. The quick coagulation furnace comprises a furnace body, an induction heater, a cooling pipe sleeve, a crucible, a rotating wheel and a roller. The induction heater, the crucible and the rotating wheel are all mounted in the furnace body. The roller is sleeved with the cooling pipe sleeve and arranged on the side face of the rotating wheel. According to the quick coagulation furnace, the roller is adopted, the outer wall of the roller is covered with a cooling device, and therefore alloy sheets can be cooled rapidly and uniformly. The obtained sheets are of ideal microstructures and in ideal external shapes.

Description

technical field [0001] The invention relates to a quick-setting furnace, in particular to a quick-setting furnace for producing permanent magnet materials. Background technique [0002] At present, in the industry of producing permanent magnet materials, the quick-setting furnaces used in the quick-setting furnace use a turntable to cool the materials after they are thrown into flakes. The cooling rate is relatively slow, and the microstructure of the as-cast quick-setting alloy flakes is not ideal, for example: columnar The uniformity of the grain size of the crystal is poor, and the width of the columnar grain is not uniform; due to the relatively slow cooling rate, the grain size is relatively large. Due to the slow cooling rate, the flakes thrown out have not completely solidified before entering the receiver, so the flakes are bonded together, forming agglomeration and agglomeration. At the same time, due to the rapid rotation of the turntable, the flakes are broken, a...

[0002] At present, in the industry of producing permanent magnet materials, the quick-setting furnaces used in the quick-setting furnace use a turntable to cool the materials after they are thrown into flakes. The cooling rate is relatively slow, and the microstructure of the as-cast quick-setting alloy flakes is not ideal, for example: columnar The uniformity of the grain size of the crystal is poor, and the width of the columnar grain is uneven; due to the relatively slow cooling rate, the grain size is relatively large

Due to the slow cooling rate, the flakes thrown out have not completely solidified before entering the receiver, which causes the flakes to stick together, forming agglomeration and agglomeration

At the same time, due to the rapid rotation of the turntable, the flakes are broken, and the flakes obtained are relatively broken
