Abstract

In order to carry out an in-depth study on the mechanism of blast descaling and improve system energy efficiency, a three-dimensional finite element model is established to simulate the behavior of destroying scale layer under different tangential velocities. The simulation results show that with the increase of tangential velocity, the increase of direct and indirect descaling areas is not obvious, but the central position of descaling area moves obviously in the X-axis direction. The increase of tangential velocity directly changes the rebound path of projectile, which can effectively reduce the collision probability between projectiles and improve the energy efficiency of blast descaling system. The tangential velocity optimization of shot blasting needs to consider not only the descaling ability of a single projectile, but also the interaction between projectiles.
