Definitions
- the present invention relates to a cooling method for a hot-rolled rolling stock with a rolling stock cross-section, in particular a metal strip, e.g. B. a steel strip, in a cooling section, with the following steps: - an initial temperature is recorded for a rolling stock in front of the cooling section,
- a coolant quantity curve is determined on the basis of a cooling path model and predetermined target properties of the rolling stock, a coolant is applied to the rolling stock location in accordance with the determined coolant quantity curve over time, and
- an expected temporal temperature curve of the rolling stock at the rolling stock point is determined via the rolling stock cross section.
- the present invention further relates to a cooling section model corresponding to this.
- Such a cooling process and the corresponding cooling section model are e.g. B. from "Steel and Iron", Volume 116 (1996), No. 11, pages 115 to 120 known.
- phase transitions of the rolling stock to be cooled e.g. B. a phase change of steel
- decisive is the thermal behavior during cooling.
- the phase change must therefore be included in the Fourier heat conduction equation.
- the modeling of the phase change in turn requires the temperature as an input parameter. This creates a coupled system of differential equations, numerically z. B. can be approximately solved by an initial value problem solver. With this approach, the Fourier heat conduction equation has to be solved together with the dynamics of the phase change.
- phase change is first modeled on the basis of an approximate temperature profile.
- the phase transition is then frozen.
- the exothermic processes during the phase change are then taken into account by heat sources in the Fourier heat conduction equation. This approach partially neglects the coupling between phase change and temperature.
- the Fourier heat conduction equation is solved coupled with the phase transition. This method also simulates exothermic processes during phase transformation by heat sources in the Fourier heat conduction equation.
- the object of the present invention is to provide a cooling method and the corresponding cooling path model, by means of which the temperature of the rolling stock to be cooled and also its phases and phase transitions are correctly described.
- the problem is solved for the cooling process in that a heat conduction equation of the shape is used to determine the temperature profile in the rolling stock in the cooling section model
- the quantities e and p are dependent on location and time, div and grad are the well-known operators divergence and gradient, which act on the location variables.
- the task for the cooling section model is achieved in that it uses a heat conduction equation for determining the temperature profile in the rolling stock
- t contains, where e is the enthalpy, ⁇ the thermal conductivity, p the degree of phase transformation, p the density and T the temperature of the rolling stock at the rolling stock point and t is the time.
- the approach according to the invention is based on the principle of energy conservation. Fourier heat conduction is therefore formulated with the enthalpy as a state variable and the temperature as a variable dependent on the enthalpy. heat source len are obviously not required. So you no longer need to be parameterized.
- the degree of phase transformation and the enthalpy represent state variables that can be calculated numerically in parallel.
- x denotes the location variable in the strip thickness direction.
- Modeling is even better if a final temperature is recorded for the rolling stock behind the cooling section. It is then possible, in particular, to adapt the cooling section model on the basis of a comparison of the detected end temperature with an expected end temperature determined on the basis of the expected temperature profile over time. The model can thus be optimized on the basis of the actual temperature recorded.
- the degree of phase conversion As part of the cooling section model, it is also necessary to determine the degree of phase conversion. This can be done in different ways. For example, it is possible to determine the degree of phase conversion according to Scheil's rule to investigate. For example, it is also possible for the degree of phase conversion (p) in the cooling section model to be based on a differential equation of the shape
- the advantage of this approach is the possibility of coupling to the Fourier heat conduction equation without giving up the possibility of using an initial value problem solver for the coupled calculation of the degree of phase conversion p and temperature T.
- h is a function like z. B. in Equation 2 on page 144 of the article "Mathematical Models of Solid-Solid Phase
- FIG. 1 shows a cooling section with a metal strip
- FIG. 2 shows a cooling section model
- FIG. 3 shows the thermal conductivity as a function of the enthalpy for two different degrees of phase conversion
- FIG. 4 shows the temperature as a function of the enthalpy for two different degrees of phase conversion
- FIG. 5 shows a heat conduction model.
- a hot-rolled rolling stock 1 runs out of a rolling stand 2 at a rolling speed v in a strip running direction z.
- a roll stand temperature measuring station 3 is arranged behind the roll stand 2.
- an initial temperature T1 is set for a rolling stock point detected on the surface of the rolling stock 1 and fed to a cooling section model 4 as an input parameter.
- the rolling stock 1 is a metal strip, for. B. a steel strip. It therefore has a width direction y
- Rolld material width b and in a thickness direction x a rolled material thickness d together result in the rolling stock cross section of the rolling stock 1.
- the initial temperature Tl of the rolling stock 1 can be across the
- Bandwidth b vary.
- the rolling stock temperature measuring station 3 is therefore preferably designed in such a way that the initial temperature T1 across the bandwidth b can be recorded several times.
- several temperature sensors arranged across the bandwidth b can be provided for this purpose. It is also possible to provide a temperature sensor, which is preceded by optics, by means of which scanning in the bandwidth direction y is possible.
- a cooling section 5 is arranged behind the roll stand temperature measuring station 3.
- the cooling section 5 has cooling devices 6, by means of which a coolant 7, typically water 7, can be applied to the rolling stock 1 from above, from below or from both sides.
- a coolant 7, typically water 7 can be applied to the rolling stock 1 from above, from below or from both sides.
- the type of application is adapted to the profile to be rolled.
- a reel temperature measuring station 8 is arranged behind the cooling section 5. With this, a corresponding final temperature T2 can be detected for the rolling stock point, which is also fed to the cooling section model 4.
- the reel temperature measuring station 8 is designed in the same way as the roll stand temperature measuring station 3.
- a reel 9 is arranged after the reel temperature measuring station 8.
- the metal strip 1 is coiled on this.
- the arrangement of the reel 9 is typical when rolling strips.
- another unit is usually provided instead of the reel 9, e.g. B. in wire rolling mills a winding layer.
- the rolling stock 1 When the reel 9 is reached, the rolling stock 1 should have a predetermined temperature and desired target structural properties G *. For this purpose, it is necessary for the metal strip 1 to have a corresponding temperature profile between the roll stand 2 and the reel 9. This temperature profile is calculated using the cooling section model 4.
- the strip thickness d, the initial temperature T1 and various parameters PAR are then fed to the cooling section model 4.
- the parameters PAR include, in particular, actual and target parameters of the strip 1.
- An actual parameter is, for example, the alloy of the metal strip 1 or its bandwidth b.
- a desired parameter is, for example, the desired reel temperature.
- the cooling zone model 4 comprises a heat conduction model 10, a heat transfer model 11 and a coolant quantity curve determiner 12.
- the cooling zone model 4 determines an expected temporal temperature curve Tm (t).
- the expected temperature profile Tm (t) is compared with a target temperature profile T * (t).
- the comparison result is fed to the coolant quantity curve determiner 12.
- the latter uses the difference to determine a new coolant quantity curve in order to bring the expected temperature curve Tm (t) closer to the target temperature curve T * (t).
- the cooling devices 6 of the cooling section 5 are then controlled accordingly by the cooling quantity profile determiner 12.
- the coolant 7 is therefore applied to the rolling stock concerned in accordance with the determined coolant quantity curve over time.
- the heat conduction equation has the form
- e denotes the enthalpy
- ⁇ the thermal conductivity
- p the degree of phase transformation
- p the density
- T the temperature of the rolling stock 1 at the rolling stock location and t the time.
- the degree of phase transformation p and its course over time must also be determined. This is preferably done using a differential equation of the form
- h is a function like z.
- ⁇ (e, p) p ⁇ (e, l) + (1- p) ⁇ (e, 0)
- ⁇ (e, l) and ⁇ (e, 0) are functions as shown in FIG.
- T (e, p) can e.g. B. by the function
- T (e, p) pT (e, l) + (l - p) T (e, 0)
- T (e, l) and T (e, 0) are functions as shown by way of example in FIG. 4.
- the heat transfer model 13 can be adapted, for example, by means of the adaptation element 13.
