Study on Hot-pressing of Continuous Press Based on Orthogonal Test

Considering the each frame unit of continuous flat press machine,in which the pressure is equal, as one hot-press stage in continuous pressing,the authors take advantage of single-opening press to simulate each frame unit and study the best hot pressing technology of 3mm,5mm,12mm and 16mm thickness fiberboard by orthogonal test.The results show that the hot pressing technology of 210℃,0.8×P_2 MPa and speed 1 000mm/s is best for 3mm fiberboard;the hot pressing technology of 210℃,0.9×P_2 MPa and speed 800mm/s is best for 5mm fiberboard;the hot pressing technology of 220℃,1.3×P_1 MPa and speed 350mm/s is best for 12mm fiberboard;and the hot pressing technology of 220℃,1.3×P_1 MPa and speed 250mm/s is best for 16mm one.
