Embodiment 1
[0095] Fig. 6 is a general flow chart of on-line setting of plate shape parameters based on the mechanism model of the double UCM skin pass unit according to the present invention. Now take the strip steel with material grade SPCC, specification 0.30mm×850mm, and deformation resistance 350MPa as an example, with the help of Figure 6 to describe the process of strip steel with a specific steel type and specification on a specific double six-roller UCM type skin pass unit. The setting process and setting results of shape parameters and related effects based on the mechanism model.
[0096] First, in step 1, collect the equipment parameters of a specific double-six-roller UCM type skin pass unit, mainly including: 1# and 2# frame working roll diameter D w1 =425mm, D w2 =450mm; 1# and 2# frame intermediate roller diameter D m1 =460mm, D m2 =473mm; 1# and 2# frame support roller diameter D b1 =1096mm, D b2 =1150mm; 1# rack work rolls, intermediate rolls and support rolls are a...

[0159] In order to further illustrate the basic idea of the present invention, now the steel strip whose material grade is EDDQ, the specification is 0.21mm×740mm, and the deformation resistance is 310Mpa is taken as an example. The comprehensive process and setting results of the flatness means on the double six-roller UCM type skin pass unit and related effects.
[0160]First, in step 1, collect the equipment parameters of a specific double-six-roller UCM type skin pass unit, mainly including: 1# and 2# frame working roll diameter D w1 =525mm, D w2 =550mm; 1# and 2# frame intermediate roller diameter D m1 =520mm, D m2 =523mm; 1# and 2# frame support roller diameter D b1 =1196mm, D b2 =1250mm; 1# frame work rolls, intermediate rolls and support rolls are all flat rolls, that is, the roll shape distribution value ΔD 1wi =0, ΔD 1mi =0, ΔD 1bi = 0; 2# frame work rolls, intermediate rolls and support rolls also use flat rolls, that is, the roll shape distribution value Δ...
