Description
Technical field
The present invention relates to non-crystal belt making equipment technical field, more particularly to a kind of non-crystal belt making copper sheathing preparation method.
Background technology
At present, the magnetic amorphous ribbon material of China's production is the new material of an energy-conserving and environment-protective, instead of traditional transformer
In silicon steel sheet, the efficiency of transformer can be improved using this material of magnetic amorphous ribbon, reduces, mitigate the volume and again of transformer
Amount, therefore be novel energy-conserving new material.
The copper sheathing on instrument chill roll that production amorphous ribbon must use is the key for determining amorphous ribbon quality and yield rate
Part.Application of the chill roll in the making of amorphous ribbon：That is, the molten steel of the magnetic material of fusing is cast in by narrow slit and revolved at a high speed
(chill roll copper sheathing is actually a copper alloy ring, and copper alloy ring two sides seals up, then for the outer surface of the chill roll copper sheathing turned
Logical cooling water cooling chill roll, gives chill roll cooling), make its rapid cooled and solidified into amorphous ribbon thin 0.025-0.04mm, because
This requires that copper chill roll surface smoothness is high, density is high, grain structure is small；If roller coarse grains, there are micropore, folder ash etc. to lack
Fall into, when molten steel is cast to copper sheathing surface it can be made heated, heat expansion the defects of pin hole, metal liquid is bonded on copper sheathing surface, make
There is hole or surface not only in belt, makes waste product.In addition, chill roll copper sheathing is using after 1~2 time, surface high-temp
Heat erosion after turning, it is necessary to reuse, until 50~0mm turning of the copper sheathing thickness on chill roll by originally to 20~30mm
After do not use.So copper chill roll can not have the defects of small shrinkage cavity, pin hole, folder ash, crackle from inside to outside, this is one
Technical indicator difficult to realize, it otherwise can influence the quality of amorphous ribbon product.
Currently used chill roll copper sheathing material mainly has chromium-zirconium-copper and beryllium copper, because chromium-zirconium-copper yield strength is relatively low, supports
Anti-crack ability is poor, and cracking, which easily occurs, in copper roller surface under thermal shock conditions repeatedly produces pit or wrinkle.Pit when spraying band
Or multiple quarter occurs for wrinkle, and strip surface can be made uneven and influence strip density and surface roughness, and then influence band
Magnetic property, reduce yield rate.It is damaged and fails in addition, the cracking of copper roller eventually results in copper roller surface, makes so as to shorten it
Use the life-span.Because the hot ability to bear of chromium-zirconium-copper is relatively low, it is typically only capable to be applied to prepare amorphous narrow strip, nanocrystalline strip and small quantities of
Measure the chill roll copper sheathing of wide strip.The intensity of beryllium copper is higher than chromium-zirconium-copper, and anti-crack ability is strong under cyclical heat stress condition, heat
Ability to bear is higher, is applicable not only to the preparation of amorphous arrowband, nanocrystalline strip and small lot wide strip, it may also be used for prepares big
The chill roll copper sheathing of batch Amorphous Wide Ribbon material.Although beryllium copper has high intensity, hardness, excellent thermal conductivity and wearability etc. are excellent
Different characteristic, but the alloy also has the shortcomings that its is intrinsic, such as because make it that alloy production cost is high containing precious metal beryllium.It is most important
Be beryllium oxide or dust it is poisonous, be hazardous to the human body, severe patient even can trigger cancer.Beryllium copper beryllium containing toxic element, no
Beneficial to the recovery of material, the waste of resource is caused.
Therefore, how existing non-crystal belt making is improved with copper sheathing preparation method, it is this it is overcome drawbacks described above
An art personnel problem urgently to be resolved hurrily.
