The steel plate is a flat-like steel cast with molten steel and pressed after cooling.
It is flat, rectangular and can be rolled directly or cut from a wide steel strip.
The steel plate is divided by thickness, thin steel plate 4 mm (the thinest 0.2 mm), medium thick steel plate 4~60 mm, extra thick steel plate 60~115 mm.
The steel plate is divided into hot rolling and cold rolling according to rolling.
The width of the sheet is 500~1500 mm; The width of the thickness is 600~3000 mm. The sheet is divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet, etc.
According to professional use, there are oil drum board, enamel board, bulletproof board, etc.; According to the surface coating, there are galvanized sheet, tin-plated sheet, lead-plated sheet, plastic composite steel plate and so on.
Product Details
The steel grade of thick steel plate is roughly the same as that of thin steel plate. In all aspects of the product, in addition to bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate and other varieties are pure thick plates, some varieties of steel plates such as automobile girder steel plate (thick 2.5~10 mm), pattern steel plate (thick 2.5~8 mm), stainless steel plate, heat-resistant steel plate and other varieties are crossed with thin plates.
In addition, the steel plate and the material said that not all steel plates are the same, the material is not the same, and the place where the steel plate is used is not the same.
1. Mainly used in the manufacture of Bridges, ships, vehicles, boilers, high-pressure vessels, oil and gas pipelines, large steel structures, etc.
2. Performance requirements
(1) High strength: Generally its yield strength is above 300MPa
(2) High toughness: the required elongation is 15% ~ 20%, and the impact toughness at room temperature is greater than 600kJ/m ~ 800kJ/m. For large welded components, high fracture toughness is also required.
(3) Good welding performance and cold forming performance.
(4) Low cold and brittle transition temperature.
(5) Good corrosion resistance.
3. Ingredient characteristics
(1) Low carbon: due to the high requirements of toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%.
(2) Add alloy elements based on manganese.
(3) Adding niobium, titanium or vanadium and other auxiliary elements: a small amount of niobium, titanium or vanadium in the steel to form a fine carbide or carbon nitride, is conducive to obtaining fine ferritic grains and improve the strength and toughness of steel. In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurization and degassing, purify steel, improve toughness and process performance, and have a durable life of more than 5-8 years.

First, raw material preparation
The first step in steel plate manufacturing is to prepare the raw materials, which are usually billets provided by the steel manufacturer. Before processing, the billet needs to be pre-treated such as surface cleaning and specification cutting to ensure that the quality and size meet the requirements.
Second, hot rolling process
Hot rolling process is the process of heating the billet to a high temperature state and then pressing it into a sheet. The process is divided into several links: heating, rolling, cooling, slitting, edging, packaging. The most critical of these is the rolling process, which deforms the steel billet to form a sheet through continuous rolling.
Three, cold rolling process
The cold rolling process is carried out after cooling the mother plate completed by hot rolling, and the main purpose is to further improve the surface finish and flatness of the steel plate. The process usually includes preparation work, sizing, too slow and too warm zone, too fast and too cold zone, buffer zone, scuttling, plate, edge, packaging and other links, each of which must control the temperature, pressure, speed and other parameters to ensure that the quality meets the requirements.
Four, pickling process
The pickling process is to soak the steel plate in an acid bath to remove impurities such as oxide and rust on the surface of the steel plate. Pickling process is one of the essential processes in the production of cold rolled steel sheet and hot rolled steel sheet.
Five, spraying process
The spraying process is the process of coating the surface of the steel plate with specific anti-corrosion, anti-rust, noise reduction, and changing the surface color of the steel plate. The selection and operation of the process need to be strictly selected and operated according to chemical properties, thickness, toughness, adhesion and other characteristics.
First, the construction field
Steel plate is a very important material in the field of construction, especially in the construction of high-rise buildings and large structures. Steel plates can be used to build Bridges, iron towers, factories, hangars, underground tunnels, flood control DAMS and other large projects. The high strength and plasticity of the steel plate can make it adapt to a variety of different forces and shape requirements, and can meet the complex needs of the building structure.
Second, Manufacturing
Steel plates are also widely used in the manufacturing industry. For example, the manufacture of cars, trains, ships, aircraft and other transportation vehicles must use a large number of steel plates, which is due to the steel plate has high strength, compression, tensile, easy processing and other characteristics. At the same time, the steel plate can also be used in the manufacturing field of light industry, machinery, home appliances, electronics, petrochemical and other industries, and has become an important material for these industries.
Third, Shipbuilding
Shipbuilding is an important application field of steel plate materials. There are many kinds of steel plates used in ship manufacturing, including general structural steel, Marine structural steel, sea corrosion resistant steel, high strength steel and so on. In the field of ships, steel plates are needed to make shipbuilding plates, ship plates, handrails, cargo decks and other parts and structural parts.
Fourth, construction machinery field
The field of construction machinery is also an important application field of steel plates. Steel plate can be used in excavators, cranes, concrete pump trucks, road machinery, pile machine and other construction machinery manufacturing. The construction machinery made of steel plate has the characteristics of strong structure, durability and high reliability, which can withstand the harsh conditions of the site environment and improve construction efficiency and safety.
In general, steel plates have a wide range of applications in construction, manufacturing, transportation and shipbuilding. Steel plate's high strength, plasticity, durability, corrosion resistance and machinability make it one of the irreplaceable materials in these industries.
