A study of Load Distribution of Semi-Continuous Bar Mill By Differential Dual Drive

Baysed on the investigation of experimental data in the differential dual drive semi-continuous bar mill φ250mm×6, the following works have been studied:
1,The D. D. D technique may be one effective way in reforming the old rolling mill in our country
.2,The load parameters which are needed for reinforcing the machinery design of the differential case have been proposed.
3,The rolling torqus and power mathematical model for steel angles have been proposed.
It is denoted that the optimal roll pass design, the mill set-up system and the flow control system should be studied in order to further develop the continuous shape rolling technique.
