Abstract

Abstract: A set of experimental equipment for atomized water spray quenching was designed to study change of the temperature drop curves of thin steel sheet 35CrMnSiA under the vertical state during spray quenching, and by using Inverse Heat Transfer module in the DEFORM software to complete the solution of the comprehensive heat transfer coefficient on the tested steel sheet. The results show that, when the tested steel sheet meets as-follow conditions, with the nozzle size of 5 mm, distance from nozzle to the sheet surface is 300 mm, and the nozzle pressure is 0.1, 0.2 and 0.3 MPa respectively, the surface heat transfer coefficient of that is correspondingly lower in the high temperature zone above 450 ℃ and the low temperature zone below 200 ℃. But the tested steel sheet can obtain a higher surface heat transfer coefficient in the middle temperature zone. Compared with the nozzle pressure of 0.1 MPa, the tested steel sheet of that has a significant improvement under the nozzle pressure of 0.2 MPa. While increasing the nozzle pressure to 0.3 MPa, the cooling capacity has little improvement.
