Numerical Simulation and Application of Immersion Depth of Continuous Casting Machine in Straight Rolling Process
According to the production practice of 165-square section continuous casting machine under the direct rolling process,the numerical simulation was carried out to study the influence of the depth of immersion on the steel flow field and fluctuation height field in the mold of high drawing speed billet continuous casting machine.On this basis,four kinds of im-mersion depths of 140,115,90 and 65 mm are simulated and calculated.When the working condition of high pulling speed is determined,the working pulling speed is stable at 4.2 m/min and the water inlet immersion depth is 90 mm,the liquid level fluctuation height is about 4.44 mm and the liquid level is stable.Through the production of special measuring tools,after production verification,the quality statistics of casting billet show that the pit and slag inclusion of casting billet are basically eliminated,and the surface quality defects of casting billet are effectively improved.
