  • the invention further relates to a casting plant with at least one mold, a casting plant system comprising this casting plant, a computer program and a computer program product.
  • the efficiency of the production process depends in particular on the solidification time, ie on the time in which the initially liquid material cools in a mold of the casting plant and solidifies, so that it can be removed from the mold.

  • the solidification time is designed to increase the production in general with regard to the operation of the casting plant under full load.
  • the casting process is subject to several non-constant and not or only limited influenceable factors. This includes, for example, the ambient temperature of the casting plant or the temperature of the materials used.
  • the previously derived and indicated object is achieved according to a first aspect of the invention by a method for controlling a casting plant with at least one mold for receiving a liquid material, wherein the liquid material solidifies during a solidification time in the mold.
  • the method comprises the steps of detecting at least one process parameter during the production process and determining the solidification time as a function of the acquired process parameter.
  • the solidification time is not given according to the invention as a constant period of time, but it is variable and is determined during the production process in dependence on at least one process parameter. In other words, the solidification time during the production process may change depending on a detected process parameter.
  • a casting plant is controlled with at least one mold.
  • a mold which in principle may have any shape corresponding to the desired shape of the component to be produced, is filled with a liquid material.
  • the starting material may be a liquid metal. To liquefy a metal this is heated accordingly.
  • the filled in the mold liquid and hot material cools in the mold and solidifies into a solid body.
  • the solidification time ie the time between the filling of the mold and the removal time of the cast Component is determined according to the invention in dependence of a detected during the production parameter process parameter.
  • a process parameter is to be understood as a parameter which is characteristic for the casting process or influences this directly or indirectly.
  • the process parameter is a parameter which is characteristic for the solidification time or influences this directly or indirectly.
  • the inventive (automatic) determination of the solidification time depending on a during the production process can be reduced.
  • the production rate and the efficiency of the production process can be increased significantly even under non-optimal operating conditions.
  • interruptions of the production process and unavoidable influences by the method according to the invention can be taken into account.
  • Even small cycle time reductions in the second range lead to significantly higher production rates.

  • the process parameter can be detected at predefinable time intervals, in particular at periodic time intervals. The time intervals can in particular be selected such that the measured values are sufficiently up-to-date in order, for example, to be able to sufficiently and timely take into account influences acting on the casting process.

  • various process parameters of the production process are suitable for determining the solidification time.
  • process parameters can be detected which characterize or influence the solidification time.
  • the temperature of the mold or the temperature of the material in the mold for the determination of the solidification time is particularly suitable. In particular, it can be deduced from the temperature of the material contained in the mold whether the initially liquid material has solidified (sufficiently) and the mold can be opened. It may be preferable to set a setpoint temperature at which it is ensured that the liquid material used is solidified so far that a cast component can be removed. In other words, the optimum removal time can be determined for each component.
  • the removal time ie the variable solidification time, may depend in particular on the current temperature of the material or component.
