Definitions
- the present invention relates to a continuous hot rolling facility suitable for producing a hot-rolled fine-grained steel sheet having a fine structure mainly composed of fine-grain ferrite.
- the pass schedule is the rolling load (load) at the second (or third) stand. ) Is often set to maximize.
- Such a pass schedule is described, for example, in Japanese Patent No. 26365976 (FIGS. 2 and 3 etc.).
- the capacity of the mill driving motor in each stand is determined by one of the following.
- hot-rolled fine-grained steel sheets that have a fine ferrite structure inside and high mechanical properties.
- Methods of manufacturing hot-rolled fine-grained steel sheets include the so-called large rolling reduction method and the controlled rolling method.In either case, rolling under high pressure is performed in some of the later stages of the finishing rolling equipment. This is because such rolling is difficult with conventional equipment that determines the motor capacity of each stand as described above.
- the large rolling reduction method is a method in which the application of high pressure to austenite grains promotes the strain-induced transformation from the austenite (a) phase to the ferrite (h) phase, thereby miniaturizing the structure. is there.
- the controlled rolling method means not only that Nb (niobium) or Ti (titanium) is contained in the component to increase the tensile strength by the precipitation strengthening action of Nb and Ti, but also to recrystallize austenite grains of Nb and Ti.
- the low-temperature rolling promotes the strain-induced transformation from the ⁇ phase to the hi-phase by suppressing the ferrite grains to make them smaller.
- the above-described rolling under high pressure to obtain a hot-rolled fine-grained steel sheet requires, for example, one that has a cumulative strain of 0.9 or more in the latter three stands. It is.
- disortion means the thickness of the steel sheet at the entrance side of each stage and the thickness at the exit side, h! Divided by the average thickness of both
- the term “cumulative distortion” refers to the distortion of each of the three subsequent stands (possibly two-stand) of the above stands (stands upstream of them are ignored because they have less influence).
- the weights of the final stand, the stand immediately upstream of the stand, and the stand immediately upstream of the final stand are given by ⁇ ⁇ and £ n- ⁇ , respectively.
- an object of the present invention is to provide a continuous hot rolling facility that is suitable for producing hot-rolled fine-grained steel sheets and is excellent in terms of threading performance (prevention of meandering) and sheet shape. Disclosure of the invention
- the continuous hot rolling equipment includes: a former stage having a plurality of stands of mills; and a subsequent stage having a plurality of stands of mills, which is disposed downstream of the former stage in the flow direction of the rolled material.
- the two or more stand mills are different diameter roll mills or extra small diameter roll mills, and the latter two or more stand different diameter roll mills or the extra small diameter roll mills are the different diameter roll mills or extra small diameter roll mills.
- Each of the stands has a driving motor having a larger capacity than the driving motor of the mill of any of the stands arranged on the upstream side.
- the two or more continuous mills in the subsequent stage including the final stand are the different diameter mills or the extremely small diameter roll mills.
- the rear stage has three or more mills, of which two mills are provided.
- three-stand mill is the above-mentioned roll mill with the different diameter or the one-mill with the smallest diameter.
- the “ultra small diameter roll mill” refers to a rolling mill in which a pair of single crawls have a small diameter of less than 600 mm.
- the “different diameter roll mill” refers to a pair of crawls in which the diameters are not equal and the equivalent roll diameter (average of the lip diameter) of the upper and lower pair of crawls is less than 600 mm in diameter.
- the equivalent diameter of a roll mill with a different diameter or the diameter of a roll with a very small diameter is desirably not more than 550 mm in terms of function, and is generally not less than 400 mm in terms of strength. It is required to be.
- the capacity of the driving motor in the two or more subsequent mills was made larger than the capacity of the motor in the stand on the upstream side. Rolling under high pressure can be performed in a strong subsequent stand.
- the mills of two or more stands in the latter stage are roll mills with different diameters or roll mills with extremely small diameters. It is unlikely to occur. This is because such a type of mill can perform rolling with a high rolling reduction (and strain) with a relatively small rolling load.
- the rolling load is small, the force acting in the sheet width direction (thrust force) is also small, so that it is difficult for meandering to occur, and the flattening of the rolling rolls is reduced, resulting in inconvenient shapes such as so-called edge drops. Is also reduced. In this way, there is little inconvenience with regard to threading properties and sheet shapes.
- the rolling reduction can be considerably increased in accordance with the motor capacity and the cumulative strain can be increased to 0.9 or more. This makes it possible to manufacture hot-rolled fine-grained steel sheets having a fine ferrite structure at the rolling equipment.
- At least one of the mills in the former stage or the latter stage has a CVC function.
- the “CVC function” controls the change of the roll gear shape by moving a rolling roll (CVC roll) formed with a continuous change in outer diameter in the axial direction in the axial direction.
- CVC roll rolling roll
- Mills with such functions are also called “CVC mills”.
- CVC mills With such continuous hot rolling equipment, it is possible to further improve the controllability of the sheet passing property and the sheet shape in the subsequent stage.
- the mill with CVC function can change and control the roll gap shape in a wide range, so that it is possible to effectively control the plate shape by preventing cracks caused by roll deflection and thermal expansion, and therefore, This is because it also has a strong effect to prevent the instability of the threading plate in the case.
- the capacities of the driving motors of the two or more stands of the different diameter roll mill or the extremely small diameter roll mill in the latter stage are set so that they do not all have the same size.
- it is set so that the capacity of the mill at the stand on the downstream side is not less than the capacity of the mill at the stand on the upstream side.
- the three-stage mill at the subsequent stage including the final stand is the different-diameter roll mill or the ultra-small-diameter roll mill; capacitance of the driving motor Isseki is a driving motor Isseki capacity of the mill of the final stand [rho [pi, the upstream side of the stand driving motor evening capacity P n-further upstream stand mils of For driving mills — capacity in the evening! If 5 ⁇ -2, then
- the strain ⁇ (or reduction ratio) should be increased as approaching the final stand. It is effective to raise it. Rolling on the upstream stand is not as powerful as that on the final or near stand in terms of its impact on the metallographic structure, so a plate with a similar metallographic structure is averagely reduced between all stands. In order to manufacture without increasing the efficiency, it is advantageous to use high pressure at the final stand or a stand close to it. Therefore, according to this rolling equipment, It will be possible to manufacture hot-rolled fine-grained steel sheets particularly efficiently in terms of equipment costs and energy consumption.
- the capacity of the driving motor of each of the two or more stands of the different-diameter roll mill or the ultra-small-diameter roll mill in the latter stage is upstream of the different-diameter roll mill or the ultra-small-diameter roll mill.
- the capacity of the driving motor of the mill in any of the stands is at least 15% larger.
- the capacity of the drive motor of the final-stand mill, P n of which capacity tends to be small among these mills
- the maximum capacity of the drive motors of the two or more stands of the different diameter roll mill or the extremely small diameter roll mill in the subsequent stage is upstream of the different diameter roll mill or the extremely small diameter roll mill. It is 30% or more larger than the capacity of the drive motor of any of the mills arranged in the mill.
- the capacity of the drive motors for those mills is ⁇ , Pn - ⁇ Pn-2, and placed upstream.
- the first is, second, ..., for each drive of the n-3 stand mode - evening capacity P l, p 2, ..., p n - the relationship between the 3,
- a curtain wall type cooling means for cooling the rolled material is disposed on an outlet side of each of the two or more stands of the different diameter roll mill or the extremely small diameter roll mill in the latter stage.
- Force-type cooling means is a type in which a large amount of cooling water is flowed in a laminar flow or near it from above and below like a curtain, and the cooling water is applied over the entire width of the upper and lower surfaces of the plate to be rolled.
- Means cooling means are provided.
- the force-wall cooling means strongly cools the rolled material by the large amount of cooling water flowing as described above, and thus effectively suppresses the temperature rise of the sheet accompanying the high-pressure rolling. Even if the plate is accelerated, it can be maintained in a suitable temperature range.
- the preferred temperature range is generally in the range from the Ar 3 transformation point to Ar 3 + 50 ° C when performing the large rolling reduction method, and 700 to 8 when performing the controlled rolling method. 0 Refers to the range of 0 ° C.
- the curtain wall cooling means is located not only at the exit of the mill at the final stage but also at the exit of multiple stages at the subsequent stage, so it occurs during rolling in the final stage and the previous stage. In addition to effectively removing the heat generated to maintain the appropriate temperature, it also exerts the effect of stopping the growth of the microstructure by cooling the rolled material immediately after rolling. In addition, since the cooling water is applied over the entire width of the rolled material, the rolled material can be uniformly cooled without being biased in the width direction.

- Figures 4 (a) and 4 (b) are diagrams showing the crystal structures of the manufactured steel sheet near the upper surface and near the lower surface, respectively.
- FIG. 5 shows the driving torque required for door mills calculated based on the pass schedule for the driving motors of each of the mills F1 to F6.
- FIG. 4 is a diagram illustrating a relationship with a torque.
- the continuous hot rolling equipment A shown in Fig. 1 is a so-called finishing mill, which has a heating furnace and a rough rolling mill on the upstream side (not shown) and a runout table on the downstream side (not shown).
- a picking machine is arranged.
- This hot rolling equipment A is a tandem arrangement of six stands of mills F1 to F6, each equipped with a rolling roll, and is capable of continuously rolling a steel sheet (rolled material) P that has been roughly rolled on the upstream side. By rolling, a hot-rolled steel sheet with a thickness of about 1 to 6 mm is manufactured.
- By setting the operating conditions it is possible to smoothly perform normal rolling for producing general steel sheets, and also to perform fine-grained steel rolling, that is, production of hot-rolled fine-grained steel sheets having a fine ferrite structure.
- Rolling equipment A is configured as follows.
- the upstream most upstream CVC mill F1 is configured as a quadruple rolling mill consisting of work rolls 1a and 1b and backup rolls 1c and 1d.
- the lb has a crown (CV C. or continuous change in diameter) as shown in Figure 2A.
- the diameter of the work rolls 1a ⁇ 1b was 700 mm, and the maximum shift amount was 100 mm in both directions.
- the other two-stage CVC mills F 2 and F 3 in the preceding stage have no difference in such configuration and function from the most upstream CVC mill F 1 in the preceding stage.
- CVC mills F1, F2, and F3 are arranged at the front stage.
- the crown (shape) of the steel sheet P In the latter-stage roll mills F4, F5, and F6, which will be described later, a thermal crown and the like due to the heat generated during processing are likely to be generated during the rolling of fine-grained steel. Therefore, these CVC mills F1, F2, F3 corrects the crown of the steel sheet in advance and reduces the middle drawing of steel sheet P.

- Both can be moved in the axial direction within a range of 100 mm in each direction. ⁇ Since the diameter of the crawl 4a is reduced to 480 mm and the diameter of the work roll 4b is reduced to 600 mm, the equivalent roll diameter, which is the average of the two, is small at 540 mm. With respect to the above configuration and functions, the other two-stage different-diameter roll mills F5 and F6 in the subsequent stage are not different from the above-described different-diameter roll mill F4. mill?
- the drive motors M5 and M6 are connected to the respective work rolls 4b of 15F6.
- the latter three stands of different diameter roll mills F 4 ⁇ F 5 ⁇ F 6 have a small equivalent diameter and drive only one crawler 4 b to apply shear force to steel sheet P. Therefore, rolling with a high rolling reduction (for example, with a rolling reduction of 50%) can be performed with a relatively low rolling load. Therefore, large reduction rolling for fine-grained steel rolling can be performed with a small rolling load, and at this time, the disadvantages due to the flattened jaw opening due to the small rolling load can also be avoided. .
- curtain wall cooling devices 7 (reference numerals 7A to 7H shown in FIG. 3) are arranged as shown in FIG.
- Each of the cooling devices 7 is composed of a large amount of room-temperature cooling water (laminator-flow) in the form of a curtain (force-to-tenwall shape) from the header provided above or below to the entire width surface of the steel sheet P.
- Sign of f Cooling means for spraying.
- the thickness (curtain thickness) of the cooling water flowing in a curtain shape is required to be 10 mm or more, and it is desirable that the thickness is about 16 mm from the viewpoint of the cooling effect.
- the amount of cooling water in each cooling device 7 can be adjusted within the range of 100 to 500 m 3 / h per unit width (1 m) of the steel sheet P, and the temperature drop of the steel sheet P due to cooling is 20 °. C / s ⁇ c or more.
- a plurality of cooling devices 7 are arranged above and below the steel plate P.
- the cooling devices 7 Above the cooling devices 7, the rear of the stand F4 and the front and rear of the stand F5, and the front and rear of the stand F6.
- cooling devices 7 C • 7 F ⁇ 7 H are arranged at the rear of the stands F 4-F 5 ⁇ F 6.
- the cooling device 7H is attached to the frame of the roller table T at the rear of the sixth stand F6, and the other cooling devices 7A to 7G are attached to the housing H of each stand.

This is to remove the cooling water on the surface of the steel sheet P by the cooling device 7G.7H, and to blow the pressurized water obliquely forward toward the surface of the steel sheet P. If such a water spray 8 is used, the cooling water on the steel plate P can be removed smoothly by the operation of the cooling device 7, and various measuring instruments (such as a thermometer, etc.) on the downstream side thereof can be used. ) Makes it possible to appropriately measure various values (such as the rolling end temperature) of the steel sheet P after rolling.
- the drive for the stand at the subsequent stage must be operated, especially at the most downstream or near the stand (mill F5'F6, etc.). It is necessary to provide a sufficient capacity (output, that is, power (kW)) to the driving motor M5, ⁇ 6, etc. of No. 2.
- output that is, power (kW)
- the rolling load per unit width of the steel sheet P increases, and the rolling torque required for the work rolls 4a and 4b increases (however, the required torque increases or decreases depending on the relationship with the sheet thickness). This is because the rolling speed increases as the sheet thickness decreases, requiring more power than when no high pressure is applied.

- maximum. Torque in Table 2 (and Table 4 below) indicates the torque value generated at each mill work roll 1 alb or 4 a4 with each motor as the output source. Show.
- the required rolling torque in the subsequent stage is higher than the pass schedule in Table 1 described above, and as shown in Fig. 5, the subsequent mills F4, F5, and F6 set in Table 2 are set.
- the torque exceeds the torque of the motor at (the torque that can be generated by a single crawl. The symbol in Fig. 5).
- Tables 3 and 4 show the capacity (power) and torque generated by the motors M1 to M6 of each of the mills F1 to F6 during rolling (while the steel sheet P is being reduced). ing. Since the steel plate P has an infinite length and rolling is not performed without breaks, the actual mode must not necessarily be the one with the continuous output rated in the table. Absent.
