Embodiment Construction

[0024] refer to Figure 4 , a complete set of finish rolling work roll configuration method, the finish rolling work rolls are configured as 7 stands, the first finish rolling stand F0 uses flat rolls, and the finish rolling work rolls F1 ~ F3 work rolls are input on the CNC grinding machine (Pomini, Italy) The CVC__1 type work roll can be ground by the table provided by SMS through the calculation of the CVC roll profile curve, and the F6 work roll adopts the CVC__2 type, which is ground by the Italian Pomini CNC grinding machine by inputting the coefficients of the equation.

[0025] F6 work roll roll type cubic curve equation is: R u0 (x)=A 0 +A 1 x+A 2 x 2 +A 3 x 3

[0026] R in the above formula 0 (x) is the radius function of CV'C roller;

[0027] The value range of A0 is 320~420;

[0028] The value range of A1 is (6.0~8.0)E—4;

[0029] The value range of A2 is (1.0~3.0)E—6;

[0030] The value range of A3 is (4.0~6.0)E—10

[0031] F0 work rolls can be ground...

Abstract

The invention relates to roller arrangement for production of band steel for hot rolled plates, in particular to a method for arranging a complete finish-rolling working roll profile, and mainly solves the technical problem that the prior roll arrangement method cannot meet the requirement of large convexity degree at the tail of a cold supply rolling material. The invention adopts the technical proposal that the method for arranging the complete finish-rolling working roll profile comprises the steps of arranging 7 finish-rolling working rolls and finish-rolling a first F0 flat roll; F1 to F3 adopt CVC rolls, and F4 and F5 adopt parabolic concave rolls; and the method is characterized in that F6 adopts a CVC roll, the roll shape of the F6 is of a curve shape, and the cubic curve equation of the curve is Ru0(x)=A0+A1x+A2x+A3x. By arranging the prior finish-rolling working roll profile, the method plays a key role in plate shape control.

Description

Technical field: [0001] The invention relates to roll configuration for hot-rolled sheet and strip steel production, and in particular to a roll shape configuration method for a complete set of finishing work rolls, which plays a key role in controlling the shape of the finish rolling work rolls by configuring the original roll shape of the finish rolling work rolls. Background technique: [0002] At present, the hot-rolled coils are produced by domestic strip hot rolling mills, and the shape control technology has become one of the key technologies. If the product wants to obtain an ideal shape, the design of the original roll shape is very important. After designing the original roll shape On the basis of the shape, how to match has become an important factor in the shape control technology. At present, the introduction of hot rolling generally adopts image 3 Roll configuration shown: F0 is flat roll, F1~F3 adopts SMS CVC roll (CVC roll is continuous variable crown roll),...
