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...

Embodiment 2

[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...

Abstract

The invention discloses a plate-shape parameter online setting method for a dual-UCM temper mill on the basis of mechanism models. The method of the invention is characterized in that: a. the equipment parameters of the dual six-roll UCM type temper mill are collected; b. the key rolling process parameters of the strip to be quickly online set are collected; c. the plate-shape parameters are roughly calculated; d. the plate-shaped parameters are finely calculated; f. the shrinkage movement of the middle rolls of the frame 1model and frame 2model of the temper mill, and the roll bending force of a work roll and a middle roll are calculated correspondingly to the roll shifting coefficient and the roll bending coefficient; furthermore, the online setting of the parameters are realized on the temper mill. When the comprehensive control method provided by the invention is adopted, the plate-shape parameter setting technique on the basis of the mechanism models can be applied online, and can meet the precision requirement on engineering, as well as can effectively ensure the plate-shape quality of the finished product, the service life of the roller, and the service life of the bent roll cylinder, thus bringing obviously economical benefits for the enterprises. The method of the invention is simple and clear and suitable for online application.

Description

technical field [0001] The invention relates to a skin-passing production technology, in particular to a mechanism model-based online rapid setting method for plate shape parameters such as bending rolls and roll shifting of double six-roller UCM type skin pass units 1# and 2#. Background technique [0002] attached figure 1 It is a schematic diagram of the production process and equipment layout of the double six-roller UCM type skin pass unit. as attached figure 1 As shown, the strip 1 is uncoiled from the uncoiler 2 and then sent to the frame. After being rolled by two stands, the strip 1 reaches a specified thickness and is sent to the coiler 3 for rewinding. The rolls of each stand include work rolls 4, intermediate rolls 5 and backup rolls 6, and the work rolls are in direct contact with the strip surface. as attached figure 2 As shown, in order to control the strip shape, during the rolling process, 1# and 2# stands have the strip shape control means of work roll...
