Definitions
- the invention relates to a method for descaling strips in a rolling mill with a scale washer and one in the direction of the belt behind the tinder washer arranged finishing line, where the belt in the tinder washer as well as within the rolling mill on the top and bottom with Water is pressurized, with a symmetrical temperature distribution generated on the top and bottom of the belt in the scale washer and in same way is maintained within the finishing train.
- Tinder is an oxide layer which among other things when rolling steel on the strip.
- the scale growth depends essentially on the surface temperature of the strip, the scaling time, the environmental conditions and the material of the tape. A higher surface temperature, longer scaling time and softer Steels lead to stronger scale growth.
- EP 0 920 929 A2 proposes, in the running direction of the belt in front of the to provide first, second and third stands of the finishing mill surface cooler, the rows of nozzles arranged opposite each other on both sides of the belt exhibit.
- a controller determines the total amount of water by every row of nozzles is sprayed onto the belt.
- the scale washer arranged in front of the finishing train consists of two on both Rows of nozzles arranged opposite each other on the belt.
- the belt is subjected to high descaling pressure (about 200 bar) water. Due to the double-sided application thermal energy is extracted from the belt with water. As a result of different Conditions on the top and bottom result in uneven temperatures. Because of the laws of scale growth described at the beginning scale growth begins immediately behind the nozzle bar again, due to the different temperatures on the edge surfaces the secondary scale grows back at different speeds. Also forms a different hardness of scale due to the unequal temperatures.
- the invention is therefore based on the object of proposing a method, that the adverse effects of different temperatures as well as different Scale growth between the top and bottom of the belt reduced within the finishing train.
- the solution to this task is based on the idea of the necessary measures to avoid uneven temperatures and scale growth already in the area of the scale washer to seize by the tape in the scale washer on several arranged one behind the other in the running direction Places with water under descaling pressure, the in Direction of travel last position on the underside at a distance from the last position located at the top and closer to the finishing train.
- Water is applied at the various points on the belt for example by means of rows of nozzles known per se.
- the distance to choose the last row of nozzles at the bottom from the last row of nozzles at the top depends on the difference in cooling effect on the top and bottom and the scale growth of the rolled material in the respective rolling mill from.
- the underside in one embodiment of the invention as a whole a larger amount of water under descaling pressure than the top of the Band are applied.
- a smaller distance between the last two Row of nozzles may be necessary due to design constraints on the rolling mill his.
- the application takes place with Water at a lower pressure in the direction of travel of the belt using rows of nozzles before and / or after the last position on the underside of the tape, at the this is pressurized with water under descaling pressure.
- the amount of water required for a symmetrical temperature distribution depends on the feed speed before the finishing train, the wear of the Descaling nozzles in the nozzle rows, from the pressure level and the Width of the tape.
- the amount of descaling pressure and low pressure on the tape applied water preferably adjustable.
- the symmetrical temperature distribution monitored on the top and bottom of the belt by non-contact, especially behind the scale washer in the direction of the belt arranged pyrometers, the temperatures on the top and bottom of the tape can be measured.
- the amount of water under lower pressure can then be as The manipulated variable of a control loop can be changed so that on the upper and Same temperatures are always measured on the underside.
- the rolling torques can be used as a control variable for the temperatures at least one scaffold of the finishing train above and below the belt be measured.
- the tape at least between the first two scaffolds of the finishing train with water is, the bottom with a larger amount of water than the top of the band is applied. Even the arrangement the upper and lower bars can be offset from each other by the distance y respectively.
- the measures taken within the finishing train can also be used with the help of a control loop can be monitored with the measured temperatures the top and bottom of the belt as a controlled variable and the amount of water supplied as stele size.
- FIG. 1 shows a finishing train 1 with one arranged upstream in the direction of travel 2 Tinder washer 3 in a hot strip mill. That is the hot strip mill continuous belt 4 is in the scale washer 3 on the top 5 and the bottom 6 of a total of four nozzle rows 7, 8 with water below Descaling pressure of about 200 bar. The at the bottom 6 in Direction 2 of the last row of nozzles 8 is closer to the finishing train 1 than the last row of nozzles 7 in the running direction at the top 5 by a symmetrical Temperature distribution on the top and bottom 5, 6 of the band 4 too achieve.
- the distance 11 between the last row of nozzles 7 at the top and the The last row of nozzles 8 on the underside of the belt must always be determined that the cooling effect of the on the top 5 of the band the bottom 6 corresponds.
- the distance 11 can, however, for design reasons, for example the space requirement of the scale washer, the arrangement of rollers or pipes may be limited. For this reason, the cooling of the Bottom 6 of the band supported by the nozzle rows 9 with low pressure.
- an excessively large distance 11 would be disadvantageous because the longer Path from the last row of nozzles 7 at the top 5 to the inlet in the finishing line 1 again a thicker layer of scale on the top can train.
- FIG. 2 shows a schematic side view of a scale washer 3, however without rows of nozzles 9 for low pressure water.
- water collecting channels 17th are arranged, which additionally reduce the cooling effect on the belt top 5 and can be used to a limited extent as an actuator.
- Figure 3 finally shows a scale washer 3, in which an application the tape 4 with water under lower pressure with a row of nozzles 9 before and two rows of nozzles 9 behind the last row of nozzles 7 on the underside of the Belt takes place on which this is pressurized with water under descaling pressure becomes.
