Abstract：

The development of forging process for a new material of 8%Cr with the alloy composition between semi-HSS and HSS for cold rolling work roller was researched from an engineering application perspective. Then, based on the phase diagram analysis, the thermal simulation experiment and the small scale forging experiment, the forging temperature range of the present alloy was determined at 950-1150 ℃, and the process execution time as well as the tonnage of forging equipment were determined by finite element analysis on the cooling status and the forging resistance during the forging process. Furthermore, according to the experimental results and simulation analysis, considering the characteristics of logistics, temperature and forging crack control during the free forging production, three-stage forging process scheme and time control measures were developed, and the first successful trial production was achieved. The results show that the reasonable forging process parameters of a new material for large free forgings are obtained by combining computer analysis and physical simulation experiments, and the low cost development of product is realized.
