Definitions
- the invention relates to a method and a casting-rolling plant for producing metal strip, in particular hot-rolled steel strip from continuously cast pre-strip in rolling lines of roughing and finishing lines.
- an ISP thin slab casting and rolling plant in which the cast thin slabs are first preformed, then wound in a coil box and unwound again, in order then to be introduced into the finishing train located nearby.
- the roughing train and finishing train are always built in close proximity in hot flat rolling mills.
- the temperature loss in the roughing mill is approx. 150 K.
- the divided slabs In order to reach the required entry temperature in the finishing mill of approx. 1100 ° C, the divided slabs must be heated to approx. 1250 ° C in walking beam furnaces. A great deal of energy is required, because on the one hand the heating energy has to be transferred to the slabs and on the other hand the temperature losses in the furnace have to be absorbed.
- the invention has for its object to make a change from the roughing to the finishing train without great energy loss and without additional facilities.
- the object is achieved according to the invention in that the casting strand in a roughing mill, which is directly connected to an outlet roller table of the continuous casting installation, is rolled to pre-strip and then wound in a coil box, and that only heat losses of the coil compared to the finish-rolling tapping - Temperature can be compensated for by heating the coil in a continuous coil furnace.
- the advantage is an energy saving due to the lower heating temperature.
- the spatial separation of the roughing train and finishing train can be disregarded by transporting the preliminary strip wound in the coil box from the coil furnace to a spatially separated finishing train.
- the spatial separation of the roughing and finishing lines is therefore no longer as important as before.
- the method can also be used in the borderline case of no spatial separation.
- a casting and rolling plant for the production of metal strip, in particular hot-rolled steel strip from continuously cast pre-strip in rolling lines of roughing streets and finishing lines is designed according to technical plant characteristics in such a way that a roughing mill is directly connected to a continuous casting system so that a winding coil box is provided for the roughing strip is arranged at the end of the roughing train and that heat losses of the coil can be compensated within a coil transport path in a continuous coil furnace which is arranged at the entrance to the finishing train.
- the advantage is an energy saving due to the lower heating temperature of the coil.
- a coil box for unwinding the preliminary strip is arranged in the material flow behind a coil task with a continuous coil furnace at the entrance to the finishing train.
- the preliminary strip therefore goes into the finishing train with a very precise finishing roll piercing temperature.
- Another advantage is that a scale washing device is arranged at the entrance to the finishing train.
- an exemplary embodiment of the casting and rolling plant for producing metal strip, in particular hot-rolled steel strip is shown as a continuous cast strip in a continuous casting plant 1, which is further rolled in rolling lines from roughing train 2 and finishing train 3.
- the roughing strip is rolled in roughing mill 2 with roughing stands 2a and 2b using the heat of fusion and then wound up in a coil box 4.
- the coil is transported on the coil transport path 5 automatically or by means of vehicles into a coil task 6, which can not only be in the vicinity, but also at a distance, and passes through a continuous coil furnace 7.
- the larger distance between the strand Casting plant 1 and the finishing train 3 can be covered without major energy loss and thus a so-called warm use of the preliminary strip can be made possible.
- reheating the coil in the continuous coil furnace 6 due to the dimensions on which it is based, for example, further energy savings are advantageous since the heat loss of the roughing mill 2 no longer has to be taken into account.
- the preliminary strip is then unwound in a further unwinding coil box 8, scooped in a cropping shear 9 and introduced into the finishing train 3 via a scale washing device 10 and finished rolled into finished strip in the finishing stands 11 to 17. Due to the division of the preliminary and finished streets at different locations, there is flexibility in the planning and execution of the systems, especially when space is limited.
