Target Tracking System Of Liquid Steel In Converter Tapping And Numerical Simulation While Rolled Slag

In order to advance steel products quality, should decrease steel slag contents inflow into ladle when converter pouring. Roughing slag detection system base on image processing could accuracy estimation roughing slag point, drive baffle proceed skimming task. The purpose of this theme is offering target tracking equipment for roughing slag detection system, through reduction complexity of collective image, advance the precision and processing speed of detection system; Against existent rolled slag phenomena at pouring terminal stage, use Fluent to numerical simulation rolled slag while converter pouring flow, derive the relation of steel slag surface content and steel slag entry reality contents together with steel slag inlet velocity.In the first part of theses is target following design, mostly mager to adjoint video image processing technilogy and automatic control.Objective is through video camera collection moving object image sequence, use image processing, gotten objective'motion parameter, with as reference to control camera always point moving object, make object always located at center of image display regional.Firstly, start with analytical system behaviour, partition system as closed-cycle control system of camera directional and image processing analytical system two part, and on this foundation ascertain control system diagram. Secondly, according to two subsystem accomplished function, partition and attain each function module, analyse and solve some problem when attain function module. Finally, in design Stepping Motor control system of camera directional.First are foundation target prediction notional, and design prediction modular; Second are design parameter initialization and Control source program of electromechanical;thirdly are foundation working flow of systematic, and present processing method point to encounter excepeional case, such as:Noise of image acquisition system and minima displacement cumulation render object shift out prediction section.At secondarily portion, against tuck slag phenomena at steel pouring terminal stage,using fluent fluid software proceed numerical simulation. Firstly mathematical modeling of need simulant portion, first foundation geometrical model,and discretization count region; Second foundation computation module, against computer calculation capable confine and convertor complicated rotational control systematic confine, make some fundamental assumption of computation module, and compute some parametric numerical when simulation,such as: Kinematic viscosity. Steel flow state.Surface tension specific numerical of molten steel and steel slag;Thirdly are account boundary condition and initial condition of simulation required. Then expatiation specific parametric select against solution procedure,such as:Situate equation solver, Situate computation schema and computation module.Finally, analyzing simulate flowfield motion result.
