알루미늄 압출 공정이란? (압출 알루미늄 가이드 2020)

오늘날 알루미늄 압출 공정 은 구조물 건설, 특히 다음과 같은 구조물에 널리 사용됩니다.

• 문
• 윈도우
• 파티션
• 통풍 및
• 반투명 정면

돌출은 오리피스를 통해 재료의 통과를 강제하는 것입니다. 일반적으로 산업에서 재료의 압출은 재료를 성형하고 특정 특성을 부여하는 데 사용됩니다.

알루미늄 압출 공정이란?

The pressing or extrusion process can be applied to aluminum profiles and bronze, brass, stainless steel or titanium. Although it is the extrusion of aluminum that has become widespread due to its low melting point (about 500 ° C).

1.1. Aluminum and steel

The extrusion process makes it possible to produce aluminum profiles in widths from 10 to 800 mm. Thanks to an unlimited range of various cross-sectional shapes. The cost of tools for making a new extruded section from aluminum is much cheaper than for making a rolled steel section.

Moreover, the downtime of the extrusion press when changing the die is significantly less. It is due to the time it takes to change the rolls of a rolling mill in the production of steel profiles.

Therefore, 알루미늄 압출 공정 produces extruded aluminum profiles. An aluminum extrusion company can carry the order according to customer drawings in order to fulfill specific tasks in a structure or product. One of the main features of the extrusion process of profiles is that they can have very thin elements.

1.2. Direct compression method: aluminum extrusion process

Aluminum profile production technology or how aluminum products are made.

The technology for manufacturing an aluminum profile is a complex process. But in order to have an idea of ​​this process, it is enough to know the basics. And in this article in a simple and understandable form, we will try to outline the whole essence of 알루미늄 압출 공정 .

So where does it all start?

At very high temperatures in production, aluminum poles are cast from aluminum raw materials. Then there is the extrusion (pressing) of the aluminum profile. There can be the process of manufacturing products from aluminum.

Aluminum extrusion process technology

First, the heating of the die starts.

What is a die?

This is a tool in the shape of which an aluminum profile is extruded. If a standard profile is made, then the tool for it is usually available at the casting factory. If we are talking about the production of a non-standard profile, then the required die is made in advance.

• Billets are loaded into the extrusion line.
• At a very high temperature, the process of heating aluminum to a plastic state takes place.
• The heated workpieces are cut with a saw.
• The aluminum is then loaded into a press and a high pressure extrusion process takes place.

The die is installed in the press. And the aluminum profile is extruded through the prepared tool. And it is automatically cut to a certain size. So you can see 알루미늄 압출 공정 is not as simple as we read it.

The resulting aluminum profile is leveled. We can say the process of "stretching" takes place.

But at the next stage, the aluminum profile is being cut into dimensions according to the order from the client.

Automatically and evenly, the profile is placed in a tank for heat in a special oven. This gives the aluminum profile its strength.

The product from the aluminum profile is ready! Next, the profile is usually packed in foil and then in cardboard.

On request, the finished product from the aluminum profile can be powder painted in any color. The standard is painted according to the RAL catalog.

Types of aluminum extrusion

The 알루미늄 압출 공정 occurs the metal billet deformation in order to adapt it to the most different applications. It all starts with the billet. This, after passing through a hole those models it for a specific applicability. In addition, it forms the aluminum profiles used in civil construction and in finished products.

2 Methods of Aluminum Extrusion

In any extrusion process, there are two ways to do the job, which depend on the ductility of the material. In the case of aluminum, the method used is high temperature extrusion.

이 현상은 주사 주사기의 작동과 유사합니다. 알루미늄 빌렛은 고압 및 고온에서 사출되어 금형으로 추진됩니다. 이를 통해 원하는 모양을 얻습니다. 이 단계 후에는 단단한 부품의 형태를 취하고 제조업체가 원하는대로 절단 할 수 있습니다.

알루미늄 압출 공정을 분류하는 방법은 무엇입니까?

토목 건축 및 가구 산업에서 엄청난 사용으로 인해 알루미늄 압출 공정 은 무한한 다양한 프로파일을 가지고 있습니다. 그들은 단면에 금속으로 둘러싸인 간격이없는 고체로 분류 할 수 있습니다.

반면에 관형 프로파일은 금속으로 완전히 둘러싸인 적어도 하나의 보이드가있는 단면을 제공하는 프로파일입니다. 단면이 부분적으로 금속으로 둘러싸인 공극이있는 반 관형 프로파일도 있습니다.

결론

알루미늄의 전성에도 불구하고 , 알루미늄 압출 공정 압출의 모든 유형을 할 수 있습니다. 몇 가지 합금 그룹이 있습니다. 이는 압출에 대한 더 넓은 범위의 특성을 의미하여 공정에서 최대의 효율성을 제공합니다. 그들 각각에는 개별적인 특성이 있습니다.

쉽게 압출 될 수 있습니다. 다른 것들은 압출 속도를 줄이는 더 복잡한 공정을 필요로합니다.
