In this paper,an imitated electromagnetic casting experimental set has been designed.The influences of some casting parameters,such as pouring temperature,cooling water flow rate and the distribution of water jet holes on the pull in of rolling faces of electromagnetic casting aluminum slabs have been investigated.It is shown that controlling the temperature field can decrease deformation of the slab;Rational cooling and solidification process have advantages for obtaining rectangle cross section of slabs.
