Abstract
The invention discloses a production method of a soft red copper belt, belongs to a production process of a red copper belt, and solves the problem of difficult rolling starting for such materials. Hard finished product belt materials after rolling are subjected to cleaning and oil removal; the shape of the whole coil of belt materials is improved by stretch bending and straightening; a large and heavy coil of finished product belt materials is cut into small coils with a weight of about 500 kg by a shearing machine; the materials are coiled by small tension force on a sleeve made of high-temperature resistant materials; annealing of the cut finished product belt materials is carried out by a roller-bottom bright annealing furnace; since the finished product materials are small in tension force and low in coil weight during coiling, and are protected by protecting atmosphere in the roller-bottom furnace, the annealed belt materials completely realize the effects of no bonding, no oxidation, and good performance, and can be directly subjected to packaging, warehousing and sale. The production method of the invention has the characteristics of small thickness, broad belt width, excellent belt shape, novel annealing process, and the like, and thus has good popularization and application value.
Description
Technical field
The present invention relates to a kind of processing method of ultra-thin soft state copper belt, especially the production method of the soft state copper belt of ultra-thin breadth.
Background technology
Copper belt is widely used in electric equipment products as a kind of good conductive material.Along with the fast development of electronic product towards high-grade, precision and advanced direction, for the requirement of copper strips material, make rapid progress especially.Thin thickness, plate face width, surface-brightening, the red copper band that hardness is low and extension property is good have become the very large product of market demand.Make a general survey of at present restraining factors that domestic copper strips processing enterprise cannot produce the soft state red copper of 0.05 * 630mm specification band mainly contain following some:
1, the template problem of material, the impact of the factors such as such thickness of strip is thin, it is cooling to be subject in the wide operation of rolling of charge level, roll shape, tension force, rolling stock starting difficulty, the very difficult control of template, often there will be starting backfin phenomenon.
2, the annealing problem of finished-product material, for copper processing, conventional strand-anneal(ing) equipment has two kinds of bell furnace and air-cushion type annealing furnaces, and the copper belt of 0.05mm twists in after cover annealing material, can produce between layers serious bonding, even when the processing uncoiling of postorder, produce bonding to tear; And while annealing by air cushion furnace due to the thickness ultrathin of material, in annealing furnace district, often can produce belt phenomenon, cause producing and cannot normally carry out.
Above 2 productions that seriously restricted the soft state copper belt of similar 0.05mm thickness, at present, the solution also not had.
Summary of the invention
Technical assignment of the present invention is that the production method of the soft state copper belt of a kind of ultra-thin breadth is provided for above-mentioned deficiency of the prior art, and the method has the features such as the material thickness processing is thin, plate face width, template is good, annealing process is novel.
The technical solution adopted for the present invention to solve the technical problems is:
1, the method adopts the hard state band of six-high cluster mill rolling 0.05 * 630mm, when rolling starts to walk, presetting 1.5 times of exit thicknesses to target thickness is rolled, after the operation of 200 meters of materials of rolling and equipment tends to be steady, the target exit thickness that again exit thickness is adjusted into 0.05mm is rolled, and with the method, has solved such material rolling difficult problem that starts to walk;
2, hard state finished product band after rolling success is through cleaning after oil removing, turn order to stretch bending-straightening machine, by stretch-bending straightening, improve the template of entire volume band, then through cutter, the finished product band that volume is heavy is greatly divided and is cut to the heavy rouleau of 500kg left and right volume, with less tension force, material webs is taken on the made sleeve of exotic material, to divide the finished product band cutting to use bright annealing furnace with roller bottom to anneal afterwards, because finished-product material tension force is when take-up little, volume is heavy little, be subject to again the protection of protective atmosphere in stove at the bottom of roller simultaneously, after annealing, band reaches non-caked completely, be not oxidized, well behaved effect, can directly pack warehouse-in sells.
Compared to the prior art the production method of the soft state copper belt of a kind of ultra-thin breadth of the present invention, has following outstanding beneficial effect: the material thickness that processes is thin, plate face width, template are good, the features such as annealing process novelty.
The specific embodiment
Production method to the soft state copper belt of a kind of ultra-thin breadth of the present invention is described in detail below.
The production method of the soft state copper belt of a kind of ultra-thin breadth of the present invention, its technical parameter requires: the hard state band that 1, adopts six-high cluster mill rolling 0.05 * 630mm, when starting to walk, rolling presets 1.5 times of exit thicknesses to target thickness (deflection of material when reducing to start to walk, to better control starting template, reach gentle start object) be rolled, after the operation of 200 meters of materials of rolling and equipment tends to be steady, then the target exit thickness that exit thickness is adjusted into 0.05mm is rolled.2, the hard state finished product band after rolling success is through cleaning after oil removing, turn order to stretch bending-straightening machine, by stretch-bending straightening, improve the template of entire volume band, then through cutter, the finished product band that volume is heavy is greatly divided and is cut to the heavy rouleau of 500kg left and right volume, with less tension force, material webs is taken on the steel sleeve of exotic material, will divides the finished product band cutting to use bright annealing furnace with roller bottom to anneal afterwards.
The band of producing ultra-thin soft state according to this production method both solved this type of strip-rolling difficult problem that starts to walk, solved again the problem that finished-product material cannot realize normarzing annealing, processed the ultra-thin soft state copper belt of surface-brightening, excellent performance.
Except the technical characterictic described in description, be the known technology of those skilled in the art.
