Detailed introduction

Introduction to main downstream industries of hot-rolled coil
Hot rolled coil is widely used in cold rolled substrate, ships, cars, bridges, construction, machinery, oil pipelines, pressure vessels and other manufacturing professions.
(1) hot-rolled coil deep processing occupation
Hot rolled coil sheet is mainly processed by hot rolled sheet with a thickness of 3.0 mm. The application range includes cold rolled coil substrate, hot rolled pickled sheet and hot rolled galvanized sheet.
Cold rolled coil substrate is one of the most important parts of hot rolled coil. The use of hot rolled coil sheet after cold rolling mainly includes cold rolled commercial coil and deep processing products such as coated sheet, color coated sheet, electrical steel and so on.
The demand of hot-rolled pickling coil mainly gathers in car occupation, compressor occupation, machinery manufacture occupation, spare parts processing occupation, fan occupation, motorcycle occupation, steel furniture, hardware fittings, electric shelves and stamping parts of various shapes.
The substrate of hot-rolled galvanized sheet is hot-rolled coil sheet. Because of eliminating cold rolling process, it has obvious cost advantage compared with hot-dip galvanized sheet, and has strong market competitiveness. It can partly replace the demand of thick standard hot-dip galvanized sheet.
(2) structural steel
Structural steel is one of the most important uses of hot rolled coiled sheets. Lower-class occupations include building steel structures, machinery, cars, petroleum and natural gas, etc.
In addition to directly using Hot-Rolled Structural Steel to make steel structure frame, many construction occupations also use cold-formed section steel and welded steel pipe made of hot-rolled coil plate as base material.
(3) structural steel for hull construction
Hot-rolled coils are also widely used in hull structural steels, mainly for the production of ocean, coastal and inland waterway shipping ships, hull, deck and other steel plates. Due to the harsh working environment of the ship, the hull is subject to chemical corrosion, electrochemical corrosion and corrosion of marine organisms and microorganisms; the hull is subjected to large wind waves and alternating loads; the shape of the ship makes its processing methods disorderly and other reasons, so the requirements for hull structural steel are more stringent.
(4) steel for pressure vessel (boiler)
Pressure vessels (boilers) with high steel requirements, the first thing is to make the container to accept different pressure and strength. According to the working conditions and processing technology of the vessel, it is required that the steel plate for the vessel should have outstanding cold bending and welding functions, excellent plasticity and resistance, short-term strength at high temperature or long-term strength functions. Pressure vessel steel plates are primarily used in the manufacture of petroleum, chemical, power plants, boilers, gas separation and storage and transportation of professional containers or other similar equipment, such as various tower containers, tanks, spherical tanks, oil and gas tanks, liquefied petroleum gas tanks, liquefied petroleum gas cylinders
And tank truck; boiler heat exchanger, reactor, boiler drum, heat exchanger, separator, high-pressure water pipe of hydropower station, turbine shell, superheater, main steam pipe and boiler chamber heating surface and other equipment and components.
(5) bridge steel
With the rapid development of bridge and railway construction in China, there is a huge demand for bridge and railway steel. Some hot rolled coils are used in bridge and railway construction.
(6) weathering and corrosion-resistant structural steels
Hot-rolled strips resistant to atmospheric corrosion, sulphuric acid dew point corrosion and seawater corrosion, as well as steel plates and longitudinal-cut strips made from these strips, are used to make structural parts such as containers, railway vehicles, oil derricks, containers containing hydrogen sulfide corrosion media in seaport construction, oil production channels and chemical and petroleum equipment.
(7) steel for oil and natural gas transmission pipeline
Steel for oil and natural gas pipelines is also the primary field of hot rolled coil, especially the West-East Gas Pipeline has led to the growth of pipeline steel demand.
(8) car structural steel
In the car steel, the amount of various steel plates including cold-rolled and hot-rolled plates accounts for more than 50% of the car steel. During this period, hot-rolled coils are widely used in trucks and buses. They are mainly used in the longitudinal beams, crossbeams, carriage crossbeams, wheels and so on of the truck frame.
