| Summary |
"A Stanat 315, two high-four high, combination rolling mill is used to cold roll annealed, low carbon steel strips. A method of measuring the rolling load was presented. The method consisted of constructing a load cell using SR-4 strain gages attached to a steel column. The load cell was placed under the hold down screw of the rolling mill and a known load was applied. The stresses from this load were transferred to the mill housing where another SR-4 strain gage was located. The strain in the mill housing was recorded at the corresponding applied load. During rolling, the strain in the mill housing was recorded and corresponded to the rolling load. Photomicrographs of the two-phase strips were shown after each pass and the rolling load-percentage reduction relationship was presented. The photomicrographs served as a guide in evaluating the effect of the rolling load on the flow of the two-phase material"--Abstract, leaf ii. |
