In accordance with the advance of the heavy chemical industry, the production of heavy duty machine-tool was very important recently. In this paper, we discussed the method of heat treatment when the large size gears was manufactured.
The surface hardening had the large size parts by flame heat treatment so that we iroduced the better manufacturing items in terms of economics.
we convinced that the best large size parts were manufactured by more study in this fields.
