Embodiment 1

[0024] Embodiment 1. After the crystallizer is installed, the effective thickness of the copper sleeve 1 is greater than 12 mm, and all the adjusting copper strips 4 are on the mold copper sleeve 1 at this time. After commissioning and commissioning, the crystallizer can spray qualified strips: the strip thickness is 28μm, the width is 142mm, the lateral thickness deviation is not more than 2μm, the lamination coefficient is not less than 86, and the iron loss is less than 0.19W / kg.

Embodiment 2

[0025] Embodiment 2. When the effective thickness of the mold copper sleeve 1 is less than 12mm, the lamination coefficient is unstable, and sometimes the lamination coefficient is less than 82. At the same time, the band begins to appear broken bands and ruffles. At this time , remove the adjusting copper bar 4 inlaid on the side of each rectangular slot 3 along the same rotation direction, that is, each rectangular slot 3 uses one adjusting copper bar 4, that is, remove half of the adjusting copper bar 4, the above-mentioned bad phenomenon disappears, and the The lateral thickness deviation of the material is mostly below 2 μm.

Embodiment 3

[0026] Embodiment 3. When the thickness of the mold copper sheath 1 reaches 5.5 mm, the band breakage is serious and it is difficult to produce stably. At this time, all the adjusting copper strips 4 are removed, and the amount of water is appropriately reduced, so that the broken belt phenomenon disappears, and stable production can be performed again.

Abstract

An embodiment of the invention provides a copper bush structure of an amorphous crystallizer. The structure comprises a water channel and adjusting copper bars. The water channel is arranged on the inner circumference of the copper bush of the crystallizer, and the adjusting copper bars are arranged in the water channel close to the copper bush. According to the thickness of the copper bush, quantity of the inlaid adjusting copper bars is adjusted timely, wall thickness of the water channel is changed by adjusting the quantity of the copper bars, and accordingly problems of non-uniform thickness of an amorphous copper strip caused by cooling capacity and cooling uniformity change of the copper bush, and flouncing and strip breakage on two sides of the strip are effectively solved, service life of the copper bush is prolonged, quality and yield of the amorphous copper strip are improved, and thermal impact resistant capacity of copper rollers is increased.

Description

technical field [0001] The invention relates to the field of amorphous manufacturing, in particular to a copper sleeve structure 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. The classic structure of the crystallizer is a nested structure. The rotating shaft is inlaid with a copper sleeve. There are several rectangular grooves on the inner circumference of the copper sleeve to connect the cooling water circuit to facilitate the circulation of cooling water. The rotating shaft is generally made of 45# steel, and the copper sleeve is generally Chromium zirconium copper or beryllium copper is used. During the use of the amorphous crystallizer, due to continuous turning and grinding, the thickness of the copper sleeve will gradually become thinner, which lea...
