Steel strip production must pass through the fire to temper and ice water baptism, after a road level can be reborn into a steel band, we need strong and resilient steel belt.
Hot rolling steel strip as a product which has been widely applied in the steel belt, on the market by the users of all ages and love, as steel belt manufacturer for you the detailed introduction of hot rolled strip steel production process.
Hot rolling strip production process mainly control the preparation, heating, descaling, roughing, cutting head, finishing, cooling, winding and sizing processes.
General for the continuous casting slab of hot rolled strip steel billet or slab, chemical composition, dimensional tolerance, bending and end shapes should comply with the requirements, for blank check should be cold pack, for billet hot charging should provide zero defect, namely the surface defects shall not be visible to the naked eye, should not have shrinkage cavity, porosity and segregation, etc.
It mainly controls the heating system of heating temperature, time, speed and temperature.
To prevent overheating, burnt, oxidation and decarburization or stick the phenomenon such as steel.
Using step furnace, good for surface quality.
Descaling device has a flat roller descaling machine, vertical roll descaling machine and the high pressure water descaling box.
Is widely used by the vertical roll rolling edge, with high pressure water (
～MPa）
Removal of iron oxide.
Accords with a requirement to ensure that the organization and properties of hot rolled strip steel, must after rolling at low temperature and high speed take-up, coiling temperature in general ~ ℃.
Coiling temperature is exorbitant, coarse grains.
Finishing is brought hot rolled steel open-book, after cutting, trimming, cut to length and planish, can be packaged into volume delivery, can also package leaflet delivery.
Hot rolled steel belt of the entire production process is more tedious, every step is related to the quality of strip steel and performance, so every step needs highly concentrate on the technical staff, can't have a little mistake and careless.
A: on the cold treatment with steel and heat treatment of steel.
