| Abstract: | Spray casting is an advanced manufacturing technology used to produce high performance clad rolls.However,the key problem of this new process is the difficulty of the interface bonding.The temperature distributions in the clad roll and its influencing factors were investigated through numerical simulation.The results show that the preheating temperature,the traveling speed and the spraying rate influence the temperature fields greatly. |
