Brief introduction of traditional hot strip rolling technology for packaging steel strip
　　 Although the long-used strip hot strip rolling process is called 'traditional' strip hot strip rolling, it does not mean that its development is terminated. Traditional strip hot strip rolling is not only still the main production at present Process (whether in terms of output and variety, it is currently mainly produced by traditional hot strip rolling), and it has changed a lot, and it is still developing with an annual output of more than 3 million tons and a bandwidth of more than 1600mm The project still needs to use traditional production technology.
　　 The so-called traditional production process refers to: the thickness of the slab (continuous casting slab) is more than 200mm, and the length is generally 4.5-9m (or up to 12.5m); a slab warehouse with a certain capacity; a heating furnace area (one set) Or multiple walking heating furnaces); with a rough rolling zone; followed by a production line with a finishing mill and an underground coiler (one to multiple).
　　The traditional hot strip rolling production line includes: slab warehouse (which is equipped with a roller table connected to the exit of the continuous casting machine or the hot billet transporter for hot charging), heating furnace area, rough rolling area, rough and finishing rolling Between the intermediate roller table and flying shear, finishing area, heat output roller table and laminar cooling device, coiling area, transportation chain, finished product warehouse (including factory transportation and transportation chain connected with cold rolling mill), etc.
　　The equipment layout of traditional strip hot continuous milking has various schemes in the rough rolling area, the exit part of the rough rolling area and the population part of the finishing rolling area.
