使用过程中教你怎样区别焊管材质?今天我来教一下大家怎么区分焊管的材质,避免在使用中产生错误,造成不必要的损失,焊管的材质区别基本分为以下几种情况:一、钢材的概念:钢材是钢锭、钢坯或钢材通过压力加工制成我们所需要的各种形状、尺寸和性能的材料。钢材是国家建设和实现四化必不可少的重要物资,应用广泛、品种繁多,根据断面形状的不同、钢材一般分为型材、板材、管材和金属制品四大类、为了便于组织钢材的生产、订货供应和搞好经营管理工作,又分为重轨、轻轨、大型型钢、中型型钢、小型型钢、钢材冷弯型钢,优质型钢、线材、中厚钢板、薄钢板、电工用硅钢片、带钢、无缝钢管钢材、焊接钢管、金属制品等品种。

How do I teach you how to distinguish the material of steel pipe? Today I'm going to teach you how to distinguish the material of steel pipes to avoid errors and unnecessary losses in use. The material of steel pipes can be divided into the following categories: First, the concept of steel: steel is ingots, billets or steel through pressure processing to make the various shapes, sizes and properties we need. Able materials. Steel is an indispensable material for national construction and Realization of the Four Modernizations. It is widely used and has a wide range of varieties. According to the different cross-section shapes, steel is generally divided into four categories: profiles, sheets, pipes and metal products. In order to facilitate the organization of steel production, order supply and management work, it is also divided into heavy rail and light rail. Large-scale section steel, medium-sized section steel, small-sized section steel, steel cold-formed section steel, high-quality section steel, wire, medium-thick steel plate, thin steel plate, electrical silicon steel sheet, strip steel, seamless steel pipe steel, welded steel pipe, metal products and other varieties.

二、钢材的生产方法

Two. Production method of steel products

大部分钢材加工都是钢材通过压力加工,使被加工的钢(坯、锭等)产生塑性变形。根据钢材加工温度不钢材同以分冷加工和热加工两种。钢材的主要加工方法有:

Most steel products are processed by pressing, so that the processed steel (billet, ingot, etc.) produces plastic deformation. According to the temperature of steel processing, steel is divided into two parts: cold processing and hot working. The main processing methods of steel are:

1、轧制:将钢材金属坯料通过一对旋转轧辊的间隙(各种形状),因受轧辊的压缩使材料截面减小,长度增加的压力加工方法,这是生产钢材最常用的生产方式,主要用来生产钢材型材、板材、管材。分冷轧、热轧。

1. Rolling: Pressure processing of steel billet through the clearance of a pair of rotary rollers (various shapes), which reduces the cross section of material and increases the length due to the compression of rollers. This is the most commonly used production method of steel products, mainly used for the production of steel profiles, sheets, pipes. Cold rolling and hot rolling.

2、、锻造钢材:利用锻锤的往复冲击力或压力机的压力使坯料改变成我们所需的形状和尺寸的一种压力加工方法。一般分为自由锻和模锻,常用作生产大型材、开坯等截面尺钢材寸较大的材料。

2. Forging steel: A method of pressing by means of the reciprocating impact force of a forging hammer or the pressure of a press to change the blank into the shape and size we need. Generally divided into free forging and die forging, often used in the production of large-scale steel, bloom and other cross-sectional steel inch larger material.

拉拨钢材:是将已经轧制的金属坯料(型、管、制品等)通过模孔拉拨成截面减小长度增加的加工方法大多用作冷加工。

Pull-and-pull steel: It is used for cold working to pull the rolled metal billets (shapes, pipes, products, etc.) through die holes to reduce the section length and increase the processing methods.

3、挤压:是钢材将金属放在密闭的挤压简内,一端施加压力,使金属从规定的模孔中挤出而得到有同形状和尺寸的成品的加工方法,多用于生产有色金属材钢材

3. Extrusion: It is a method of processing steel products with the same shape and size by putting metal in an airtight extrusion jacket and applying pressure at one end so that metal can be extruded from a prescribed die hole.

三、黑色金属、钢和有色金属 在介绍钢的分类之前先简单介绍一下黑色金属、钢材钢与有色金属的基本概念。

3. Before introducing the classification of steel, the basic concepts of ferrous metal, steel and non-ferrous metal are briefly introduced.

1、黑色金属是指铁和铁的合金。如钢、生铁、铁合金、铸铁等。钢和生铁都是以铁钢材为基础,以碳为主要添加元素的合金,统称为铁碳合金。生铁是指把铁矿石放到高炉中冶炼而成的产品,主要用来炼钢和钢材制造铸件。 把铸造生铁放在熔铁炉中熔炼,即得到铸铁(液状),把液状铸铁浇铸成铸件钢材,这种铸铁叫铸铁件。铁合金是由铁与硅、锰、铬、钛等元素组成的合金,铁合金是炼钢的原料之一,在钢材炼钢时做钢的脱氧剂和合金元素添加剂用。

1, black metal is the alloy of iron and iron. Such as steel, pig iron, ferroalloy, cast iron and so on. Steel and pig iron are based on iron and steel, carbon as the main additive elements of the alloy, collectively known as iron-carbon alloy. Pig iron refers to iron ore into the blast furnace smelting products, mainly used for steelmaking and steel casting. Cast pig iron is melted in a melting furnace, and then cast iron (liquid) is obtained. Liquid cast iron is cast into cast steel. This kind of cast iron is called cast iron. Ferroalloy is an alloy composed of iron and silicon, manganese, chromium, titanium and other elements. Ferroalloy is one of the raw materials for steelmaking. It is used as deoxidizer and additive of alloy elements in steelmaking.

2、把炼钢用生铁放到炼钢炉内按一定工艺熔炼,即得到钢。钢的产品有钢锭、连铸坯和直钢材接铸成各种钢铸件等。通常所讲的钢,一般是指轧制成各种钢材的钢。钢材钢属于黑色金属但钢不完全等于黑色金属。

2, smelting pig iron into a steelmaking furnace, smelting according to a certain process, that is to get steel. The products of steel include ingot, continuous casting billet and straight steel for various steel castings. Generally speaking, steel refers to steel rolled into various steels. Steel is black metal but steel is not equal to black metal.

3、钢材有色金属又称非铁金属,指除黑色金属外的金属和合金,如铜、锡、铅、锌、铝以及黄铜、青铜、铝合金和轴承合金等。另外在工业上还采用铬、镍、锰、钼、钴钢材、钒、钨、钛等,这些金属主要用作合金附加物,以改善金属的性能,其中钨、钢材钛、钼等多用以生产刀具用的硬质合金。以上这些有色金属都称为工业用金属,钢材此外还有贵重金属:铂、金、银等和稀有金属,包括放射性的铀、镭等钢材。

3. Steel non-ferrous metals, also known as non-ferrous metals, refers to metals and alloys other than ferrous metals, such as copper, tin, lead, zinc, aluminum and brass, bronze, aluminum alloys and bearing alloys. In addition, chromium, nickel, manganese, molybdenum, cobalt steel, vanadium, tungsten, titanium and other metals are also used in industry. These metals are mainly used as alloy additives to improve the properties of metals, including tungsten, steel titanium, molybdenum and other cemented carbides for cutting tools. These non-ferrous metals are known as industrial metals, steel in addition to precious metals: platinum, gold, silver and rare metals, including radioactive uranium, radium and other steel.

四、钢材的分类

Four. Classification of steel products

钢是钢材含碳量在0.04%-2.3%之间的铁碳合金。为了保证其韧性和塑性,含碳量一般不超过1.7%。钢的主要元素除铁、碳外,还有硅、锰、硫、磷等。钢的

Steel is an iron carbon alloy with carbon content between 0.04%-2.3%. In order to ensure its toughness and plasticity, carbon content is generally not more than 1.7%. The main elements of steel include iron, carbon, silicon, manganese, sulphur and phosphorus. Steel
