  鋁板生產(chǎn)過程中有哪些困難?

What are the difficulties in the aluminum plate production process?

  眾所周知,任何產(chǎn)品在生產(chǎn)過程中難免會(huì)出現(xiàn)一些質(zhì)量問題,有的是機(jī)械導(dǎo)致,有的是人為操作影響的;鋁板也不例外,在鋁板帶生產(chǎn)過程中,因?yàn)樵O(shè)備或者人員操作失誤等原因容易出現(xiàn)質(zhì)量問題,今天小編帶您了解一下生產(chǎn)過程中常見的問題都有哪些?

As is well known, there are inevitably some quality problems in the production process of any product, some caused by machinery, and some influenced by human operation; Aluminum plates are no exception. In the production process of aluminum plates and strips, quality problems are prone to occur due to equipment or personnel operation errors. Today, the editor will take you to understand what common problems are in the production process?

  在帶坯軋制成各種鋁板半成品和成品的過程中,以及在卷材精整、退火、轉(zhuǎn)運(yùn)、包裝等工序的生產(chǎn)過程中,不可避免的會(huì)出現(xiàn)一些缺陷。這些缺陷的產(chǎn)生,一部分是鑄錠、鑄軋帶坯本身的缺陷。時(shí)在注錠、鑄軋工序可暴露,有時(shí)不能發(fā)現(xiàn),而在后續(xù)的進(jìn)一步加工過程中才能暴露;另一部分是在帶箔材軋制、精整、退火、轉(zhuǎn)運(yùn)、包裝等工序生產(chǎn)過程中產(chǎn)生的。這些缺陷的產(chǎn)生大部分是由于設(shè)備故障、違反操作規(guī)程、工藝參數(shù)調(diào)整不當(dāng)、操作人員技術(shù)不夠熟練和其他種種原因造成的。在鋁箔的生產(chǎn)過程中,造成鋁板質(zhì)量缺陷有許多種,主要是大量的針孔、厚度超差、平整度差、各種原因的斷帶等,減少這些缺陷,對(duì)提高箔材質(zhì)量是很有意義的。鑄軋、熱軋坯料中的夾雜、氣道、軋制過程中的金屬和非金屬壓人、擦、劃傷以及厚度不均等都能給鋁箔軋制造成很大困難.引起斷帶、針孔、厚度超差等。

In the process of rolling various semi-finished and finished aluminum plates with billets, as well as in the production processes of coil finishing, annealing, transportation, packaging, etc., some defects are inevitable. The generation of these defects is partly due to the defects of the ingot and the cast rolling strip itself. Sometimes it can be exposed during the ingot casting and rolling process, but sometimes it cannot be detected, and it can only be exposed during subsequent processing; The other part is generated during the production process of foil rolling, finishing, annealing, transportation, packaging, and other processes. The majority of these defects are caused by equipment malfunctions, violations of operating procedures, improper adjustment of process parameters, inadequate technical proficiency of operators, and various other reasons. In the production process of aluminum foil, there are many types of quality defects caused by aluminum sheets, mainly a large number of pinholes, thickness deviation, poor flatness, and various reasons for strip breakage. Reducing these defects is meaningful for improving the quality of foil materials. The inclusions, air passages, metal and non-metal pressure, friction, scratches, and uneven thickness in casting and hot rolling billets can all cause great difficulties in aluminum foil rolling, leading to strip breakage, pinholes, and thickness deviation.

  劃傷:劃傷、擦傷、碰傷是鋁板表面呈現(xiàn)的斷續(xù)或連續(xù)的.單條溝狀傷痕。一般是尖銳物與箔材表面接觸后相對(duì)滑動(dòng)時(shí)產(chǎn)生的。產(chǎn)生的主要原因:軋輥、導(dǎo)輥表面有尖狀缺陷,或粘有硬雜物;剪切、合卷、分切的機(jī)械導(dǎo)輥、導(dǎo)路有尖狀缺陷或枯有雜物。擦傷:由于物體間棱與面,或面與面接觸后發(fā)生相對(duì)滑動(dòng)或錯(cuò)動(dòng)而在箱材表面造成的成束(或組)分布的傷痕。擦傷產(chǎn)生的主要原因:鋁板在加工生產(chǎn)過程中,與導(dǎo)路、設(shè)備接觸時(shí),產(chǎn)生相對(duì)摩擦而造成擦傷;坯料松卷、松層或有燕窩狀端面缺陷;軋制時(shí)張力使用不當(dāng),開卷時(shí)產(chǎn)生層間錯(cuò)動(dòng)而產(chǎn)生擦傷。碰傷:鋁卷與其他物體相撞后,在箱卷表面或端面產(chǎn)生的傷痕。其表現(xiàn)為表面或端面有部分凹陷。碰傷的主要原因:各生產(chǎn)工序吊運(yùn)或存放不當(dāng);運(yùn)輸及搬運(yùn)過程中碰傷;鋁箔卷在退火料架或包裝臺(tái)上由其他突出物磕碰而產(chǎn)生傷痕。

Scratches: Scratches, abrasions, and bumps are intermittent or continuous grooves on the surface of aluminum plates. It is generally generated when sharp objects come into contact with the surface of the foil and slide relative to each other. The main cause of occurrence is that there are pointed defects or hard debris adhering to the surface of the rolling and guide rollers; The mechanical guide rollers and guides for cutting, winding, and slitting have pointed defects or debris. Scratches: Bundles (or groups) of distributed scars on the surface of box materials caused by relative sliding or displacement between edges or surfaces of objects, or after contact between surfaces. The main cause of scratches: During the processing and production process of aluminum plates, relative friction occurs when they come into contact with the guide and equipment, resulting in scratches; Loose coils, layers, or bird's nest shaped end defects in the raw material; Improper use of tension during rolling can result in interlayer misalignment and scratches during uncoiling. Collision: The scratches on the surface or end face of the aluminum coil after colliding with other objects. It manifests as a partial depression on the surface or end face. The main cause of collision: improper lifting or storage in various production processes; Collisions during transportation and handling; The aluminum foil roll is scratched by other protrusions on the annealing rack or packaging table.
