Abstract
The utility model relates to the technical field of strip-casting machines for producing amorphous strip steel rolled stock and relates to a strip-casting copper roller for a strip-casting machine. The strip-casting copper roller takes the shape of a cylinder, and is made of aluminum oxide dispersion copper material. The excircle diameter Phi of the strip-casting copper roller is 200 mm to 2000 mm, the inner circle diameter Phi is 100 mm to 1800 mm, and the height is 100 mm to 2000 mm. A linear, ring-shaped or spiral line shaped water tank is processed on the inner surface of the strip-casting copper roller. The strip-casting copper roller provided by the utility model has the advantages that the softening temperature can reach 930 DEG C, and meanwhile, the conductive performance, the heat conducting performance, the rigidity and the intensity are greatly improved by compared with those in the prior art. Therefore, the service life of the strip-casting copper roller is prolonged, particularly when wide strip steel rolled stock is produced, the thickness of the strip steel rolled stock is guaranteed to be uniform.
Description
Technical field
The utility model relates to the production amorphous band and gets rid of band machine technology field, relates in particular to a kind of band machine that gets rid of with getting rid of band copper roller.
Background technology
Amorphous, nanometer crystal alloy, or be called glassy metal, it is a kind of new material that comes out the seventies in 20th century; Be to utilize fast cooling technology; With the molten steel one-shot forming is that thickness is 30 microns strip, and its internal structure is an amorphous or nanocrystalline, has high magnetic conductivity and low-loss characteristics.Manufacturer's major part of domestic amorphous, nano-crystalline thin ribbon all is to get rid of the band machine through single roller to produce through rapid quench technology, is that amorphous gets rid of the critical component on the band machine and get rid of band copper roller.In getting rid of the work of band machine, high temperature foundry alloy liquation to getting rid of on the band copper roller of rotation at a high speed, gets rid of that band copper roller rotates at a high speed and inner through water quench through nozzle ejection, and motlten metal liquid cools off fast and is thrown out of and processes strip getting rid of band copper roller surface.Therefore get rid of band copper roller and be in the cold and hot conversion of long periodicity, it must have the performance of good heat-conducting and thermal fatigue resistance.
Getting rid of band copper roller abroad mainly is to be produced by Germany and Japan, adopts chromium zirconium copper product, and its intensity and electrical and thermal conductivity performance are considerably beyond the domestic production properties of product.The domestic band copper roller manufacturer of getting rid of; Its product all adopts red copper, chromiumcopper, chromium zirconium copper product; Though but fine softening temperature of red copper thermal conductivity and anti-fatigue performance are too poor; Can the narrower amorphous band in production broadband, and produce when needing the broad amplitude band of usefulness as transformer etc., then make thickness of strip uneven or deform easily.Though chromiumcopper and chromium zirconium copper product strength character increase, compare also with the aluminum oxide dispersion copper product and differ greatly.And softening temperature is low, and thermal fatigue resistance is just poor, and it is short service life to get rid of band copper roller.
The utility model content
The technical problem that the utility model will solve is, provides a kind of new band machine that gets rid of to be with the copper roller with getting rid of, to solve above-mentioned prior art existing technical problem when the production wide-format webs.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of band machine that gets rid of is characterized in that with getting rid of band copper roller the said band copper roller that gets rid of is cylinder barrel shaped, and it is processed by the aluminum oxide dispersion copper product.
The said outside diameter φ 200mm～φ 2000mm that gets rid of band copper roller, interior circular diameter φ 100mm～φ 1800mm, height 100mm～2000mm.
The said inner surface that gets rid of band copper roller is processed with linear, annular or spiral yarn shaped tank.
Said aluminum oxide dispersion copper gets rid of band copper roller, A1 in its chemical composition
20
3Content is 0.03%～0.8%.All the other are Cu.
The beneficial effect of the utility model is: because the utility model is processed by the aluminum oxide dispersion copper product; The advantage of aluminum oxide dispersion copper product is existing than red copper and high intensity that manys and the softening temperature of chromium zirconium copper; The heat-conductivity conducting performance that red copper about 85% is arranged again; Its softening temperature can reach 900 ℃, and the softening temperature of red copper has only 250 ℃, and the softening temperature of chromium zirconium copper is 500 ℃.Higher softening temperature can stop the crystallization again of material, prevents grain growth, improves the ability of thermal fatigue resistance.Because the heat endurance of aluminum oxide dispersion copper is fabulous; Its softening temperature is up to 930 ℃, and conduction and heat conduction and hardness and intensity can both keep finely simultaneously, therefore makes the life-span of getting rid of band copper roller be greatly improved; Especially when the production wide-format webs, can guarantee that thickness of strip is even.

The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As depicted in figs. 1 and 2, a kind of band machine that gets rid of is characterized in that with getting rid of band copper roller 1 the said band copper roller 1 that gets rid of is cylinder barrel shaped, and it is processed by the aluminum oxide dispersion copper product.
The said outside diameter φ 200mm～φ 2000mm that gets rid of band copper roller 1, interior circular diameter φ 100mm～φ 1800mm, height 100mm～2000mm.
The said inner surface that gets rid of band copper roller is processed with linear, annular or spiral yarn shaped tank.
Said aluminum oxide dispersion copper gets rid of band copper roller 1, A1 in its chemical composition
