Increase of seriality of steel casting on continuous casting machines

Types of producible operations for increase of seriality of steel casting on continuous casting machines:

1.1. Physical modeling of the processes that progress in an intermediate ladle of a continuous casting machine:

  • fabrication of a model of an intermediate ladle for a continuous casting machine. The model constitutes a precise copy (reduced not more than threefold) of an intermediate ladle of a continuous casting machine;
  • examination of control capabilities of the process of metal flowing from a steel-pouring ladle into an intermediate ladle;
  • examination of the impact nature of a metal stream coming from a steel-pouring ladle and affecting the nature of liquid phase agitation in an intermediate ladle;
  • evaluation of the nature of metal agitation with integumentary clinker in an intermediate ladle, which accompanies the process of casting;
  • examination of metal motion dynamics (convectional flows) in the content of an intermediate ladle from the entry of a falling flow to the outflow of steel into crystallizers.

1.2. Mathematical modeling of processes that progress in an intermediate ladle of a continuous casting machine:

  • monitoring of all processes that progress in an intermediate ladle of a continuous casting machine;
  • comparison of data of physical and mathematical modeling of all processes that progress in an intermediate ladle of a continuous casting machine.

 


Results of physical modeling of processes that progress in an intermediate ladle:

  • selection of an optimal construction of a metal collector of a ladle (bucket-shaped type with holes for direction of metal flows);
  • if necessary (selection of optimal construction and location of dams and partitions).


According to the data of industrial trial at two different plants, average seriality of steel casting made up 45 melts. Maximal seriality made up 64 melts. Savings made up more than one dollar per one ton of assorted steel.
