Definitions
- the invention relates to an existing hot strip mill with a Walking beam furnace, a reversing scaffold downstream of this and if necessary. Scissors and / or descaling devices, and a following Hot strip finishing train for the production of thin, austenitic rolled Hot strip.
- Such hot strip mills are in operation in large numbers. With These hot strip mills can be used for hot strips with a thickness of Roll 1.5 mm, at best 1.2 mm. This is where these hot strip mills meet to its limits. A further reduction in the strip thickness is not possible with these roads. There are two reasons: On the one hand, the mean temperature of the strip at the exit of the last stand of the hot strip finishing mill approx. 890 ° C to 930 ° C do not fall below to guarantee an austenitic rolling. On the other hand, the speed at the exit of the last scaffolding is allowed the hot strip finishing train does not exceed approx. 11.0 to 12.5 m / s, otherwise the hot strip on the outlet roller table is not can be guided more properly and then reeled. In addition, the threading in the hot strip mill at such high speeds is problematic.
- the slabs are cut in several in the fore line of a hot strip mill Roll stitches rolled out to a supporting strip. It forms over the Length of the opening strip a temperature wedge, which is essentially due the decrease distribution during rolling and the rolling speeds being affected.
- the hot strip finishing mill is turned into the hot strip finishing mill introduced, which is at its edges Temperature level at the lower limit of that for the first roll stand the hot strip finishing line has the necessary temperature, the Belt center temperature is however correspondingly too high.
- the strip center temperature as mentioned above, be at least approx. 890 ° C to 930 ° C.
- skidmarks areas of the material in the walking beam furnace, which lie on the beam, be cooled more than the rest Area of the input material, so that through the transverse to the rolling direction walking beam running in the feed material transverse to the rolling direction colder areas of the tape arise.
- These so-called “skidmarks” must also be entered at the hot strip finishing line be taken into account from the temperature, so that if necessary. the opening temperature in the area outside the skidmarks still is considerably higher than the strip edge temperature in the range of skidmarks.
- the invention has for its object existing hot strip mills, by means of which tape down to thicknesses of 1.5 to 1.2 mm can be rolled to rebuild or retrofit that the strip thickness can be lowered below 1 mm, the retrofitting should be as inexpensive as possible.
- the temperatures in the edge area can be adjusted using the compensating oven of the opening act, from the beginning or end of the band and possibly existing Compensate skidmarks so that a supporting strip with a homogeneous Temperature is generated, the temperature of the equalization furnace leaving the preliminary strip to the lowest for the hot strip finishing train necessary input temperature can be set.
- the pre-strip temperature is constant over length and width for absolutely stationary process conditions in the finishing train to care. This creates the best possible conditions for rolling of tapes with minimal end tape thicknesses.
- induction heaters are assigned to the compensating furnace, you can selectively heated areas of the belt or the temperature level be influenced overall. Will the Compensating furnace arranged parallel to each other, so this can by simply moving it horizontally or vertically in parallel brought to the rolling line for loading or unloading in the rolling line become.
- this allows the support strip to enter the rolling line in one cycle be involved, with the actual heating device in parallel is arranged to the rolling line.
- the compensating furnace is designed as a roller hearth furnace is to make sure there are no skidmarks can.
- the compensation furnace can be removed from the Extend the rolling line and a conventional roller table in its place drive in.
- Figure 1 shows a walking beam furnace 1, which in the rolling direction 2 Reversing frame 3 connects.
- the feed e.g. B. blocks, heated, and from the furnace 1 to the reversing frame 3 given, where it was rolled to support strip in several passes becomes.
- FIG. 2 shows between the reversing stand 3 and the hot strip finishing train 6 a compensating furnace 7.
- the compensating furnace 7 has several Recording places 8 to 8 '' ''. These are in the direction of arrow 9 displaceable, the arrangement shown both for one in essentially horizontal as well as for a substantially vertical arranged compensation furnace 7 should stand.
- an induction heater 10 is shown in front of the expansion furnace 7.
- FIG. 3 shows the furnace 1, the reversing stand 3 and the hot strip finishing train 6. Furthermore, two ferries 11 and 12 can be seen, between which the consecutively arranged recording spaces 13 to 13 '' ' of the compensating furnace 7 'are arranged.
- the support is brought back to ferry 11 and here from the Move the rolling line out into the line of the receiving positions 13 to 13 '' '.
- the pre-strips are removed and after pushed into the ferry 12, by means of which they again in the Rolling line and from there to hot strip finishing line 6 become.
