Method C / Al neutron absorbing material sheet

The present invention discloses a continuous casting and rolling preparing B4C / Al neutron absorbing material sheet, comprising the steps of: a) providing a body B4C particles and molten aluminum, the molten aluminum matrix B4C particles are added under stirring and stirred composite; 2) applying an electromagnetic field to melt the aluminum matrix containing B4C particles flowing through the headbox; 3) applying ultrasonic vibrations to melt the aluminum matrix containing B4C particles flowing through the casting nozzle; and 4) from the casting mouth aluminum matrix containing a melt flowing B4C particles using a twin roll continuous casting to obtain B4C / Al neutron absorbing material sheet. Continuous casting method of the present invention prepared B4C / Al neutron absorbing material sheet by a twin roll under the ultrasonic oscillations and an electromagnetic coupling continuous casting, rapid cooling solidification structure so that the composite grain refinement and uniform B4C particle distribution, unbiased poly produce.
