What are the varieties and uses of packaging steel strip and hot-rolled strip steel?
Answer: Hot-rolled strip products are mainly supplied to cold rolling mills as raw materials in the form of steel coils. At the same time, they also directly sell hot-rolled steel coils and finished products to users and the market, namely flat steel coils, sub-coil steel coils, Slitting narrow strip steel coils and cross-cutting steel plates. In recent years, pickled hot-rolled steel coils have entered the sales market as finished products.
The main steel grades of hot-rolled steel coils used as raw materials for cold rolling mills of this enterprise and other enterprises are low carbon steel (including ultra-low carbon steel) and general carbon structural steel, which are used for cold rolling mills to produce oriented silicon steel, Raw material steel coils for oriented silicon steel and stainless steel sheet and strip are also produced by hot-rolled wide strip steel rolling mills. The specification range of the cold rolling mill raw material steel coil is: thickness 1.5-6.0mm, width 600-1900mm.
The types and uses of hot strip steel directly for users and sold to the market are as follows:
(1) Ordinary carbon structural steel strip. Used in the manufacture of building structures, lifting and transporting machinery, engineering, agricultural and construction machinery, railway vehicles and various other structural parts.
(2) High-quality carbon structural steel strip, including welded structural steel strip supplied according to foreign standards. A large number of applications, and used to make cars, tractors, harvesters, and mechanical components that require excellent stamping performance and welding performance, petroleum storage tanks, pressure vessels, ships, and bridges.
(3) Low-alloy high-strength structural steel strip. It is used to manufacture machinery manufacturing, vehicles, chemical equipment and other equipment structures that require higher strength, better formability and stable performance, large-scale factory steel structures, important projects and bridge structures, etc.
(4) Atmospheric corrosion resistance and high weather resistance steel strip. It is used in the manufacture of railway passenger cars, refrigerated cars, railway wagons, ore cars and structural parts of various transportation vehicles. It is also used in the manufacture of ships and railway containers, oil derricks, various construction machinery and transportation machinery.
(5) Seawater corrosion-resistant structural steel strip. It is used in oil derricks, seaport construction, oil production platforms, shipbuilding, as well as the manufacture of corrosive liquid containers containing hydrogen sulfide in the chemical and petroleum industries and railway transportation vehicles.
(6) Plate and strip steel series for automobile manufacturing.
(7) Steel for container. It is specially used for manufacturing container side panels, door panels, top panels, bottom panels, frames, columns and other components.
(8) Steel for pipelines. Pipelines for oil and natural gas transportation are used to manufacture buried welded steel pipes and longitudinally welded steel pipes.
(9) Steel for welding gas cylinders and pressure vessels. Used to manufacture liquefied gas cylinders and acetylene gas cylinders, pressure vessels and boilers with higher working temperature, etc.
(10) Steel plate for shipbuilding. Used in the manufacture of inland river hulls and superstructures, superstructures and bulkheads of ocean-going ships.
(11) Mine steel plate. Used in the manufacture of mining hydraulic supports, mining engineering machinery, mining carts, mining scraper conveyors, and other wear-resistant structural parts of mining machinery.
