Description

Technical Field

[0001] The invention relates to the field of stainless steel plates, and in particular to a hot-rolled stainless steel plate width detection system. Background Art

[0002] Hot-rolled stainless steel plates have relatively low strength and poor surface quality (oxidation and low finish), but good plasticity, generally medium and thick plates. Cold-rolled plates have high strength and hardness, high surface finish, generally thin plates, and can be used as stamping plates. After the straight coils are processed by trimming, trimming, trimming, and multiple straightening, flattening and other finishing lines, they are cut or re-rolled to become: hot-rolled stainless steel plates, flat hot-rolled steel coils, longitudinally cut strips and other products. If the hot-rolled finishing coils are pickled to remove the oxide scale and oiled, they become hot-rolled pickled coils. The hot-rolled stainless steel plate has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-proof.

[0003] Since stainless steel plates are the raw materials for manufacturing other related products, if the physical width of the stainless steel plates exceeds the set width numerical range, other related products manufactured from the stainless steel plates will obviously have width deviations. In serious cases, these products cannot be equipped in the application site for normal use. Therefore, a high-precision width analysis mechanism is needed to realize non-contact numerical analysis of the current width of each stainless steel plate. Summary of the invention
