Production Process

Production process route
20g (Ti) boiler plate is a kind of steel with high requirements for comprehensive mechanical properties, relatively pure steel, and the composition of melting components and microalloying elements that are more sensitive to the effects of various properties. Therefore, the key to the 20g (Ti) production process is to optimize the melting composition, reduce the total amount of inclusions in the steel, select appropriate microalloying elements, use controlled rolling, improve the quality of the plate, and stabilize the application of aging impact. The technical route of 20g is: high-quality molten iron → purification treatment → smelting of composition optimization and steel purification → microalloying and refining of molten steel → protective casting → high-quality slab → controlled heating → temperature-controlled rolling → plate shape and thickness control →Control cooling→product.

Boiler container plates are used to manufacture petroleum, chemical, gas separation, gas storage and transportation containers or other similar equipment, such as various towers, heat exchangers, storage tanks, tank trucks, etc. High-quality carbon structural steel and low-alloy high-strength For structural steel plates, see GB6654-1996. 1 Dimensions and weight: According to the provisions of GB709, the usual thickness * width dimensions are 6~120*600~3800 (mm).

Smelting and refining process
(1) Adjust the internal control components to increase the lower limit of manganese content to 0.65%.
(2) Adopt the “three-in-one” refining operation of line feeding, temperature adjustment and argon blowing.
(3) Strictly control the pouring temperature.
(4) The content of microalloying element Ti is increased from 0.003% to more than 0.008%. (5) Adopt the whole protection pouring process to reduce the absorption of N.

Classification

Classification by thickness
Thin steel plate <4 mm (the thinnest 0.2 mm), thick steel plate 4-60 mm, extra-thick steel plate 60-115 mm. The width of the thin plate is 500-1500 mm; the width of the thick plate is 600-3000 mm. The steel type of thick steel plate It is basically the same as the thin steel plate. In terms of products, in addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multi-layer high-pressure vessel steel plates, which are purely thick plates, some types of steel plates such as automobile beam steel plates (thickness 2.5-10 mm), pattern Steel plates (thickness 2.5-8 mm), stainless steel plates, heat-resistant steel plates, etc. are crossed with thin plates. 2. The steel plate is divided into hot-rolled and cold-rolled according to rolling.

Classified by purpose
(1) Bridge steel plate (2) Boiler steel plate (3) Shipbuilding steel plate (4) Armor steel plate (5) Automobile steel plate (6) Roof steel plate (7) Structural steel plate (8) Electrical steel plate (silicon steel sheet) (9) Spring steel plate ( 10) Other

Classified by structure
1. Steel plate for pressure vessel: Use capital R to indicate at the end of the grade. The grade can be expressed by yield point or carbon content or alloying elements. Such as: Q345R, Q345 is the yield point. Another example: 20R, 16MnR, 15MnVR, 15MnVNR, 8MnMoNbR, MnNiMoNbR, 15CrMoR, etc. are all represented by carbon content or alloying elements.
2. Steel plate for welding gas cylinders: Use capital HP to indicate at the end of the grade, and its grade can be expressed by yield point, such as: Q295HP, Q345HP; it can also be expressed with alloying elements, such as: 16MnREHP.
3. Steel plate for boiler: Use lowercase g to indicate at the end of the brand name. Its grade can be expressed by yield point, such as: Q390g; it can also be expressed by carbon content or alloying elements, such as 20g, 22Mng, 15CrMog, 16Mng, 19Mng, 13MnNiCrMoNbg, 12Cr1MoVg, etc.
4. Steel plates for bridges: Use lowercase q to indicate at the end of the grade, such as Q420q, 16Mnq, 14MnNbq, etc.
5. Steel plate for automobile beam: Use capital L to indicate at the end of the grade, such as 09MnREL, 06TiL, 08TiL, 10TiL, 09SiVL, 16MnL, 16MnREL, etc.
