Accompanying drawing explanation
Fig. 1 is the block diagram of Plate Production method.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment:
The production method of steel plate, as it is shown in figure 1, described steel plate is thickness is 6 ~ 7mm steel plate, described steel plate produces on 4100mm Heavy Plate Rolling Line, and wherein production process comprises the following steps:
1) on 4100mm Heavy Plate Rolling Line, it is (190 ~ 230) mm*(1530 ~ 2000 by specification) mm*(2200 ~ 3800) blank heating of mm is to after 1150 ~ 1200 DEG C, after making billet surface and heart portion homogeneous temperature, it is rolled into specification for (80 ~ 100) mm*(1600 ~ 3300 through roughing mill) mm*(2150 ~ 8000) the middle blank of mm;
2), after centre blank being cooled to room temperature, specification is cut into for (80 ~ 100) mm*(1600 ~ 3300) mm*(2150 ~ 3300) two cut blanks of mm;
3), after two cut blanks being heated to 1150 ~ 1200 DEG C, it is rolled into, through roughing mill, the roughing intermediate blank that thickness is 25 ~ 30mm;
4) multi-pass rolling is used to become thickness to be 6 ~ 7mm steel plate through finishing mill roughing intermediate blank;
5) thickness 6 ~ 7mm steel plate is carried out straightening processing, carry out after cooling shearing and collect, obtain thickness 6 ~ 7mm steel plate finished product.
Method in the present embodiment, considering 4100mm Heavy Plate Rolling Line heating furnace heating efficiency, roughing mill ability, roughing mill ability, the aspects such as user's request, and for facilitate follow-up rolling, when rolling for the first time, it is (190 ~ 230) mm*(1530 ~ 2000 by specification) mm*(2200 ~ 3800) blank of mm is rolled into specification for (80 ~ 100) mm*(1600 ~ 3300) mm*(2150 ~ 8000) the middle blank of mm, when second time rolling, middle blank is cut into specification for (80 ~ 100) mm*(1600 ~ 3300) mm*(2150 ~ 3300) two cut blanks of mm.
Overcoming steel plate cooling fast in the method production process, steel plate deformed drag is big, deform the difficulties such as uneven so that thickness 6 ~ 7mm steel plate mechanical performance of production is qualified, plate shape is good.Solve the problem that 4100mm Heavy Plate Rolling Line can not be utilized in prior art to produce thickness 6 ~ 7mm steel plate.
In described step 1, in order to improve heating quality, optimize heating steel billet technique, it is ensured that steel billet tapping temperature >=1150 DEG C, during steel billet tapping temperature >=1150 DEG C, billet surface and heart portion homogeneous temperature, reduce rolling deformation drag.
In described step 4, in described step 4,7 passes are used to become thickness to be 6 ~ 7mm steel plate through finishing mill roughing intermediate blank, wherein, the drafts of the first passage finishing mill is 10 mm ~ 13mm, the drafts of the second passage finishing mill is 3 mm ~ 4mm, the drafts of the 3rd passage finishing mill is 2 mm ~ 3mm, the drafts of four-pass finishing mill is 1 mm ~ 2mm, the drafts of the 5th passage finishing mill is 0.5mm ~ 1.5mm, the drafts of the 6th passage finishing mill is 0.3 mm ~ 0.5mm, and the drafts of the 7th passage finishing mill is 0.3 mm ~ 0.5mm.Front 3 passages increase single pass drafts in finishing mill ability allowed band as far as possible, reduce every time temperature drop.4 passages next mainly adjust drafts according to steel plate profile situation, in real time to ensure the original glacing flatness of steel plate.
In described step 4, in the finish rolling operation of rolling, close the roller-way cooling water in finish rolling region, the body of roll cooling water of regulation precision rolling working roll, make precision rolling working roll the body of roll cooling water in 20 ~ 30 DEG C of temperature, to reduce operation of rolling light plate temperature drop, it is ensured that finishing temperature is in reasonable interval;When rolling, adjust AGC oil column height 10 ~ 60mm so that rolling horizontal plane mates whole roller plane.During rolling, adjust AGC oil column height 10 ~ 60mm according to rolling horizontal plane.Rolling elevation of water regulates mainly by step pad and AGC hydraulic cylinder, because it is different in the same working roll of different times, backing roll roller roller footpath, in order to ensure that rolling horizontal plane mates with whole roller plane, need to be realized by adjustment AGC oil column height so that rolled plate original plate shape is good.
When being embodied as, roughing feeding thickness 25~30mm, finish rolling start rolling temperature is 1050 ~ 1140 DEG C.In the operation of rolling, all first passage of finish rolling beats water under high pressure, closes and cools down water outside the roller-way of rolling region, turns roll cooling water down, to ensure finish rolling finishing temperature 840~900 DEG C.
This optimization order improves rolling mill practice thick, smart, improves steel plate rolling process temperature and controls and passage arrangement, reduces thermal loss, it is ensured that steel plate flatness.
In described step 5, when steel plate after aligning is cooled down, steel plate velocity of liquid assets between regulation finishing mill and 11 roller straighteners, reduce the loss of process of circulation steel billet temperature, and 11 roller straightener roller-way cooling water, make the body of roll cooling water control of 11 roller straighteners in 20 ~ 30 DEG C of temperature, open strong temperature in the range of 630 ~ 760 DEG C.
In described step 5, when steel plate is aligned, use three passage aligning modes that steel plate is carried out straightening processing.Wherein every time is crossed strong amount and controls at 1 ~ 3mm;During the first passage aligning, steel plate is completed from the beginning to the end the first passage aligning, during the second passage aligning, steel plate is completed to the end from tail the second passage aligning, during the 3rd passage aligning, steel plate is completed from the beginning to the end the 3rd passage aligning, thus eliminates the residual stress that steel plate produces in the operation of rolling, make steel plate straight.
In described step 5, after thickness 6 ~ 7mm steel plate is carried out straightening processing, steel plate is cooled to less than 60 DEG C by cold bed, shears collection and obtain thickness 6 ~ 7mm steel plate finished product.Before cooling, cold bed can be emptied, will steel plate emptying on cold bed so that steel plate is quickly through cold bed, it is ensured that products in circulation are smooth and easy, it is to avoid cause steel plate secondary wooden dipper wave or watt curved because inhomogeneous cooling is even.
Finally illustrate is, above example is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that, technical scheme can be modified or equivalent, without deviating from objective and the scope of technical solution of the present invention, it all should be contained in the middle of scope of the presently claimed invention.
