Problems solved by technology

As the molten steel falls, the molten steel forms a line parallel to the axial direction of the copper sleeve on the side wall of the copper sleeve, and the molten steel coincides with the rectangular groove. It enters the rectangular groove at the center, which means that the cooling water enters the rectangular groove from one side or the middle and starts to contact the molten steel indirectly. To a high trend, which will lead to inconsistent cooling temperature of molten steel, poor consistency of magnetic properties of amorphous strip

Embodiment 1

[0019] Embodiment 1: as figure 1 , 2 , shown in 4, a kind of amorphous crystallizer copper sleeve, comprises copper sleeve body 1, the inner wall of copper sleeve body 1 is provided with some V-shaped grooves 2 arranged at equal intervals, the intersection of two sides of V-shaped groove 2 Located on the center line of a circle of the inner wall of the copper sleeve body 1, a ring of sealing grooves 3 are provided at both ends of the copper sleeve body 1; the included angle of the V-shaped groove 2 is 30~160°, and the groove width of the V-shaped groove 2 is 4-8mm, the wall thickness of the walls on both sides of the V-shaped groove 2 is 2-6mm, and the wall panels on both sides of the V-shaped groove 2 are twisted and bent.

Embodiment 2

[0020] Embodiment 2: as image 3 As shown, with reference to Example 1, an intermediate partition 4 that divides the V-shaped groove 2 into two halves is provided on the center line of a circle of the inner wall of the copper sleeve body 1 .

[0021] When working, the cooling water flows out from the center line of the inner wall of the copper sleeve body 1, the copper sleeve body 1 rotates, and the molten steel falls from the outer ring of the copper sleeve body 1 along the axial direction of the copper sleeve, and contacts the outer wall of the copper sleeve body 1 , the cooling water on the inner wall of the copper sleeve body 1 cools the molten steel to form a strip. When the copper sleeve body rotates, the direction of rotation of the copper sleeve ensures that the two free ends of the V-shaped groove 2 are located at the front. Due to the cooling in the V-shaped groove 2 Water flows out from the sharp corner of the V-shaped groove 2, and when the two sides of the V-shape...

Abstract

The invention discloses a copper bush of an amorphous crystallizer. The copper bush comprises a copper bush body, a plurality of V-shaped grooves are formed in the inner wall of the copper bush body at equal intervals, the intersection point of the two edges of each V-shaped groove is located on the annular center line of the inner wall of the copper bush body, and the two ends of the copper bush body are each provided with an annular sealing groove. By means of the copper bush body, temperatures of cooling water on each line, coincident with the axis direction of the copper bush body, on the wall of the copper bush body can be coincident, and the magnetic performance of amorphous strips produced through the copper bush is excellent.

Description

technical field [0001] The invention relates to the field of amorphous crystallizers, in particular to a copper sleeve for an amorphous crystallizer. Background technique [0002] Amorphous crystallizer is a wheel type crystallizer used to produce amorphous ribbon. The core component of the amorphous crystallizer is the copper sleeve, and the core technology is the waterway structure. There are several rectangular grooves on the inner circumference of the copper sleeve of the traditional amorphous crystallizer to connect the cooling water circuit to facilitate the circulation of cooling water. As the molten steel falls, the molten steel forms a line parallel to the axial direction of the copper sleeve on the side wall of the copper sleeve, and the molten steel coincides with the rectangular groove. Entering the rectangular groove at the center means that the cooling water enters the rectangular groove from one side or the middle and starts to contact the molten steel indir...
