Furnace control systems for reheating furnaces celFCS-rht

Furnace control systems for reheating furnaces celFCS-rht

In contrary to old approaches, which only observe single elements in the furnace (e.g. critical material), celano GmbH has developed a new three step procedure for their furnace control system celFCS-rht (celano Furnace ControlSystem Reheating) which observes the whole material inside the furnace, thus optimizing the operation mode while abstaining from the usual simplifications.

1. step observer
The current material temperature is determined (energy bilance in the furnace, 3-dimensional thermal conduction equation). Heat carriage through convection and radiation as well as heat conduction and added energy through combustion are incorporated during this step.

2. step prediction
The expected fure temperature distribution for all materials inside the furnace is calculated with the help of prediction. The observer is called multiple times to simulate the future material movement and the planned changes of furnace temperatur. The prediction then returns the expected chronological sequence of the local furnace temperature for every slab as a result.

3. step optimization
The setpoint assignation results from the optimization with the aid of an evolutionary algorithm. Changed setpoints (so called scenarios) are simulated based on the current situation. With a so called fitness function the chronological sequence of material temperature (results of the prediction) for every scenario is evaluated. By the use of mechancial selection, heredity, mutation and consideration of fitness results the evolutionary algorithm creates new scenarios, which in return are simulated by the prediction. The determination of the scenario with the highest fitness result is goal of the optimization. The flexibility of the fitness function, which can easily be modified for customer specific focal points is a huge advantage. The different (potentially contradictional) goals can also be weighted.

To ensure the online capabillity of the system, even though complex and computing time intensive operations are used, the software is designed with parallel algorithm for multi processor systems.

Observation of thermoelements
A special function inside the modell is the observation of thermoelemts. Since the model is recreating the furnace situation at any point in time, an additional algorithm can identify a difference in the meassured temperature of thermoelements and offer corresponding messages.

Furnace control system for cont. annealing line celFCS-cal

Furnace control system for continous annealing line celFCS-cal

The model celFCS-cal (celano Furnace Control System-Continuous-Annealing-Line) is responsible for gas rate controll respectively temperature control in a continous annealing line. After implementation of the model, furnace control is executed at all points in time and not just in case of strip changes.

With Gas rate control respectively temperature control of a continous annealing furnace without a model the problem can occure that...

in case of speed changes for an assembly line because of factory problems, strip devaluation is necessary because of overheating.

depending on the furnace operator, temperature regulation is executed differently.
complex strip changes can only be performed by experienced operators
in complex situations many settings have to be configured and observed by the operators

Because of those points the model celFCS-cal was developed:

  • to react quickly in case of speed reduction
  • to unify furnace control
  • to control the furnace during complex strip changes
  • to relieve the operators

To be able to realize those tasks, the model puts a multitude of boundary conditions into consideration, e.g.:

  • the heat absorption of strips can differ from each other, even if steel brands, dimensions, setpoints and production speed of the strips are the same.
  • the difference between an openly heated furnace part and an indirectly heated furnace part in terms of performance have to be considered during a strip change. As a general rule the indirectly heated furnace part is responsible for shimming and the quicker openly heated furnace part is responsible for fine control.
  • the stored heat from the cladding, which in the case of increased thermal output gathers heat and in the case of decreased thermal output emits heat.
  • the maximum allowable overheating temperature for the strip temperature, to allow for a strip change without under temperature

Furnace control systems for batch annealing shops celFCS-bas

Furnace control systems for batch annealing shops celFCS-bas

The model celFCS-bas (celano Batch Annealing System) is used for calculation of set point values for a given batch in a batch anealing shop (offline mode). In case of disturbance set points can be corrected automatically by the help of the online observation (online mode).

In a batch annealing shop coils with

  • different dimensions (width, weight, strip thickness)
  • different composition
  • different aim in quality

have to be put together in batches.
Depending on the position inside the batch coils have to be heated differently. In most batch annealing shops the setpoints are determined by the use of tables, which in most cases use input parameters in their most simple form, containing total weight of batches, minimal strip thickness and maximum strip width for each quality.
The combination of qualitys and the combination of speciffic dimensions are in most cases very limited. Since the table would be to large and unclear, the position and dimensions of a coil inside the batch are not considered.
In case of limiting the possible combinations of different coils to strictly, it is possible that single coils in the storage can not be annealed with any other coil aviable.If the tolerance is to high there are problems with highly inhomogeneous batches, e.g. heavy coils that do not reach the aimed quality and have to be annealed a second time, since the table does not survey every coil on its own.

The modell celFCS-bas was since developed

  • to consider each coil with their dimensions, alloy content and setpoints as well as their position inside the batch, with the decrease of quality spread and the avoidance of second annealing in mind.
  • to allow for a broader spectrum of possible coil combinations while still achieving the demanded setpoints.
  • to reduce heating time, if for a given quality cooling with heating hub is used later on (avoidance of the use of glue).
  • to achive the same type of quality, even if the heating gradient is changed, intermediate level are implemented or the temperature during a waiting phase is changed.
  • to determine setpoint graphs for coils of new qualitys.

This functional range was reached by the use of a mathematical modell, which recreates the whole batch annealing process whith the occuring heat flow and the whole annealing in a time pattern.

Furnace simulator celFCS-sim

Furnace simulator celFCS-sim
In combination with the celano furnace simulator celFCS-sim, which can simulate the most diverse reheating furnaces and materials, the furnace control system celFCS-rht can also be used to answer additional questions like the analysis and recalculation of heating processes, the influence of changes in the furnace geometry and performance or the influence of changes of material data and is ideal for further development of production processes and execution of studies.
The time needed for the implementation of the online control system can be reduced if simulations were performed in advance.

About us

Company details

True to their company motto „thinking the process" celano GmbH offers tailor made solutions to their customers since 2002.

Their products are the link between automation level (level 1) and production planning systems (level 3), focused mostly towards the metal- and steel industry. Solutions are based on the knowledge of modern, reliable technology in hard- and software. For a few years the main focus has been a new thermodynamic furnance model.

Besides design, realization and comissioning of customized software systems as well as the selection and installation of the required hardware, celano GmbH also offers maintenance and support for their software.

The development strategy of celano GmbH is based on a strict separation of process components from system components. By separating the process data acquisition from its visualization the user interface can be accessed from any location, single components can easily be replaced and new interfaces can easily be added.

Every process is controlled and optimized all the time by celano GmbH.
