Annealed Steel Coil
The hot-rolled steel coil obtains the required geometric size, compression ratio, plate shape, etc. after pickling and cold rolling, and the dirt and grease on the surface of the strip steel are cleaned by chemical, physical and electrochemical methods through the degreasing unit, which is conducive to obtaining the required finish on the surface of the steel plate after annealing, and the work hardening and the recovery of deformed grains and the required surface cleanliness are removed by annealing the annealing furnace.

Description
The hot-rolled steel coil obtains the required geometric size, compression ratio, plate shape, etc. after pickling and cold rolling, and the dirt and grease on the surface of the strip steel are cleaned by chemical, physical and electrochemical methods through the degreasing unit, which is conducive to obtaining the required finish on the surface of the steel plate after annealing, and the work hardening and the recovery of deformed grains and the required surface cleanliness are removed by annealing the annealing furnace. After annealing, enter the leveling unit to level the steel plate, and eliminate the yield platform inside the annealed steel plate through the reasonable use of tension and rolling force, so as to obtain the mechanical properties required by the customer, as well as the further improvement of the plate type, and obtain the required plate surface cleanliness through the wet leveling mode.
There are two types of cold rolling annealing processes:hood annealing and continuous annealing
| Project | Bell annealing | Continuous annealing |
| Annealing method | In the form of stackingin bell furnaces, batch type | The strip steel continuously passes through the unsealed annealing furnace and continuous type |
| Grain (degree) | Cake crystals, Levels 6-8 | Equiaxed crystals, Levels 8-10 |
| Annealed steel grade | CO、DO、DDQ | CQ, DQ, DDQ and HSS and other high-strength steels |
| Temperature range | The annealing temperatureis in the single-phaseregion (a+Fe3), and thetemperature is nothigher than 720°C | The annealing temperatureis in the duplex region (a+y), and the temperaturecan reach 850'C |
| Merit | Uniform annealing.good mechanical properties.less limited by orderspecifications, small equipment size, individual control of each equipment, simple process | The production speed is fast,the efficiency is high, the costis low, the surface finish is goodand the performance uniformityof the whole coil strip is good |
| Shortcoming | The production speedis slow, the cycle is long,the cost is high, the surfacefinish is relatively poor,and the performanceuniformity of the wholecoil strip is poor | The mechanical propertiesare poor, limited by the orderspecifications, the equipmentis large in size, and theprocess is complex |
| Applicable Industries | Stamping, automotive industry,home appliances, etc. | Home appliance industry |

These sheets exhibit robust durability, corrosion resistance, decorative appeal and formability, finding extensive application across construction, home appliances, solar energy and transportation sectors.
Customized Pre-painted Galvolume Steel Coils (PPGL)
Colour-coated steel sheets: Organic coatings applied to steel sheets yield rich colours, lustre, and customisable surface finishes. These organic layers shield the steel from atmospheric corrosive agents, extending its service life.
HWAFONE's plain-rolled galvanised and pattern-rolled galvanised steel sheets offer superior performance with smooth surfaces, delivering excellent corrosion resistance, formability, and coating adhesion.
Coating Protection Mechanism: In environments with high concentrations of pollutants such as industrial emissions, acid rain readily forms. This acid rain creates acidic permeation on the surface of colour-coated steel sheets, accelerating corrosion of the substrate beneath conventional coatings and leading to phenomena such as blistering and delamination.
