板坯连铸结晶器内钢液液面波动水模研究

In order to investigate the regularity of liquid level fluctuation of mold with different process parameters in a steel mill, a 1:0.6 water model was established based on the mold of slab continuous casting, and the influence of process parameters such as outlet angle of SEN, immersion depth, blowing flow rate, casting speed, SEN blocking and other parameters on the surface level fluctuation of liquid steel in the slab caster mold. The results show that as outlet angle of SEN or immersion depth increases, the smaller the value of surface level fluctuation; as blowing flow rate or casting speed increases, the greater the value of surface level fluctuation. When the degree of obstruction on both sides of the nozzle is the same, the fluctuation value of the liquid level increases with the increase of the degree of obstruction.When the degree of blockage on both sides of the nozzle is different, the velocity of the liquid steel outlet on the side with the degree of blockage is smaller than that on the other side, and the fluctuation of the liquid level is larger The results can provide reference for optimization of mold process parameters.
