Features
The core of hot-rolled coils lies in the "high-temperature rolling – continuous coiling" process. With applications spanning construction, machinery, home appliances, and other industrial fields, it is an extremely versatile steel product.
I. Core Process (Streamlined Key Steps)
Heating of Raw Material: Continuous casting slabs or steel ingots are fed into a heating furnace and heated to 1,100–1,300°C to ensure plasticity.
Multi-pass Rolling: Roughing mills roll the material into intermediate slabs, which are then processed by finishing mills to precisely control thickness (typically 2.0–20mm) and dimensional accuracy.
Cooling and Coiling: After rolling, the material is rapidly cooled via laminar cooling and finally coiled into continuous steel coils by a coiling machine. Inspection follows before storage.
II. Main Applications (by Sector)
Construction Engineering
Used in manufacturing load-bearing components such as steel structure factories, bridges, and supports. It can also be processed into hot-rolled sections and sheet piles.
Highly adaptable and capable of withstanding complex stresses, it is a cost-effective and widely used steel in construction.
Machinery Manufacturing
Serves as raw material for mechanical parts, equipment housings, and vehicle frames. It is processed into finished products through cutting, welding, and machining.
Subsequent heat treatment can optimize strength to meet requirements for toughness and load-bearing capacity in machinery.
Automotive and Home Appliance Sectors
In the automotive industry, it is used for frames, chassis, and wheels. In home appliances, it is used for refrigerator shells and air conditioner brackets.
For some high-precision products, pickling and annealing are required to remove surface oxide scale before further processing.
Piping and Container Applications
Used in the production of spiral welded pipes and longitudinal welded pipes for water, gas, and oil transmission pipelines.
It can also be processed into pressure vessel shells, meeting relevant standards for strength and weldability.
Raw Material for Further Processing
Serves as the core base material for cold-rolled coils. After cold rolling, galvanizing, or color coating, surface precision and corrosion resistance can be enhanced.
