Definitions
- the invention relates to a hot rolling mill according to the preamble of claim (see for example DE-A-44 02 402) for rolling thin hot strip for a wide range of different difficult to form Material and method for operating such a hot rolling mill.
- Hot rolling mills which follow Continuous casting and equalizing ovens are arranged.
- Hot rolling mills allow hot strips to be formed with varying degrees of difficulty
- Roll materials with thicknesses of 1.5 to 1.2 mm, with the tape at the exit the last rolling stand still austenitic structure has.
- the belt speed at the exit of the last rolling mill is also easy constructed, the hot rolling following units such.
- Watzbanddicke is at least with these roads not possible for easily formed materials.
- the average temperature of the band at the output of the last framework the hot strip mill the temperature required for austenitic rolling (about 860 ° C) do not fall below
- the speed at the exit of the last stand of the hot strip mill approx. 12.5 m / sec. do not exceed, because the hot strip otherwise with simple means on the Outlet roller table no longer run properly and then reeled can be.
- reels that wrap around at rotational speeds of over 15 m / sec. have to be accelerated very expensive, expensive and difficult to control.
- Hot strip mills When rolling difficult to form material can be with the seven-stand Hot strip mills can reach even smaller thicknesses than 1.2 mm, since Due to the large rolling work austenitic structure behind the last mill stand even at lower speeds is still encountered.
- the hot rolling plant is for easily deformable material with small final thicknesses, however not suitable.
- the drive elements of the hot rolling mill become more stressed at higher speeds and wear out faster, so that elaborate drive components, reel and scissors and much more precise and dynamic control mechanisms are provided need to ensure the desired band qualities.
- the invention is based on the object, a hot rolling mill and a Method for operating the hot rolling mill so to design. that after the rolling process at initial thicknesses below 1.2 mm, in particular less than 1 mm even when rolling easily deformable materials still strip temperatures which ensure austenitic rolling and yet the exit velocity of the rolling stock a speed of 15 m / sec. Not exceeds, so that there are easier manageable workflows, the Wear and tear of the system is reduced and the costs are also simple Aggregates can be kept low.
- the invention will be explained in more detail with reference to a drawing.
- the drawing shows a hot rolling mill for material that is difficult to form can be operated in each case so that regardless of the material used and despite the different conditions for everyone Materials final rolling temperatures occur at the last stand, which is an austenitic Rolls guaranteed and speeds less than about 15m / sec. be achieved.
- the hot rolling plant consists of a Dünnbrammeng discernstrom 1 whose Strand guide is so adjustable that thin slab thicknesses of about 45 to 70 mm be achieved at the output of Dünnbrammeng discernstrom 1.
- the endless cast Thin slabs are divisible by a pair of scissors 2. You can do that Set slab lengths equal to the length of a finished rolled coil or a correspond to multiple of them.
- the sliced slabs are in a roller hearth furnace 3, which serves the temperature compensation at a temperature e.g. 1150 ° C held.
- the roller hearth furnace 3 is followed by a pair of scissors. 4 which is only used in the event of an accident.
- the one seven-stand rolling mill 7 with the rolling sizes F1 to F7 follows.
- a cooling section 8 is provided, which is in the strip running direction a flying shears 9 connects, which in the case of semi-endless or Continuous rolling is used.
- the hot rolling mill ends with two reels 10, which may also be designed as a Rotorhaspler altematively.
- an intermediate scaffolding device 6 arranged between the rolling stand F1 and the rolling stand F2 .
- the thin slab caster will be used 1 adjusted so that depending on the desired final thickness and Casters production slabs with thicknesses between 45 and 70 mm preferably 55 mm application. All seven scaffolds will be F1 to F7 hired.
- the scaffolding descaling device 6 is inactive. At this Driving style can be controlled by the high rolling forces and in the to be rolled, hard-to-formate material to be introduced large work rolled strip thicknesses at Exit of the rolling stand F7 can reach below 1 mm whereby the speed of about 15 m / sec. is not exceeded and yet rolled strip with Austenitic structure is present.
- the thin slab caster 1 When rolling easily deformable material with a final thickness of less than 1 mm the thin slab caster 1 on thin slab thicknesses between 45 and 50 mm.
- the mill stand F1 is either inactive or is one Smoothing made with a small decrease.
- the smoothing effect causes the Slab surface is smoother, so that behind the tinder scrubber 5 a can build a more uniform scale layer.
- the active scaffolding descaling device 6 makes it easier to remove the newly formed scale. That less descaling agent is applied to the slabs, as if the scaffold F1 were not set for smoothing.
- the scaffolds F2 to F7 are usually made slightly stronger than in the driving style, in which all seven scaffolding are employed. By operating only the stands F2 to F7 become lower end roll speeds reached. Due to the lower inlet slab thickness and the stronger Setting up the scaffolds F2 to F7 will nevertheless be finish rolling thicknesses below 1 mm achieved, wherein the rolling temperature in the austenitic microstructure having.
