08 Nov 1974TL;DR: In this paper, a rolling mill with computer programmed for absolute lock-on AGC control rolls material having absolute aim gage without using an active thickness gage in the control loop is presented.
Abstract: Rolling mill with computer programmed for absolute lock-on AGC control rolls material having absolute aim gage without using an active thickness gage in the control loop. Computer is programmed to calculate; (a) lock-on length of rolled material, (b) mill stretch using a simplified subroutine, (c) calibration-corrected roll gap, (d) a lock-on thickness error relative to aim gage, (e) a corrected roll gap reference signal as a function of a constant lock-on thickness error and other variable thickness errors caused by changes in mill stretch and roll gap occurring after lock-on, and (f) a rate-sensitive variable gain of the corrected roll gap reference signal to reduce thickness errors to substantially zero as rapidly as possible.

16 Apr 1990TL;DR: In this article, a sliding gate valve is used to prevent the aspiration of air into the molten metal orifices during discharge of molten metal from a ladle or tundish.
Abstract: A molten metal slide gate valve for use on a ladle or tundish The slide gate valve uses a stationary upper plate having a groove formed in its lower face around the periphery of the plate The groove is connected to a source of a nonoxidizing gas under pressure to provide a gas seal around the molten metal orifices in the slide gate valve and prevent the aspiration of air into the molten metal orifices during discharge of the molten metal from the ladle or tundish

TL;DR: In this article, the effect of fine or coarse carbide particles on abnormal grain growth in a low carbon steel subjected to small deformation was studied, where grain growth was induced in a decarburizing atmosphere at 1450 ‡F (788 ‡C).
Abstract: The effect of fine or coarse carbide particles on abnormal grain growth in a low carbon steel subjected to small deformation was studied. Grain growth was induced in a decarburizing atmosphere at 1450 ‡F (788 ‡C) in order to study the effect of the initial carbide particle morphology on the subsequent motion of the grain boundaries at temperature. In this manner, the primary influence of second phase particles during straining could be evaluated. Transmission electron microscopy revealed that the large carbide particles exhibit a larger dislocation density area around them than the small carbide particles after straining up to ten percent. At higher strains, cell formation begins and the dislocation distribution is more uniform. Both coarse and fine carbide particle samples demonstrated three stage abnormal grain growth at strains below 10 pct. An incubation stage, which decreases with increasing strain, is followed by an abnormal grain growth stage, in which certain selected grains grow at the expense of other grains. Finally an equilibrium stage is reached in which the largest grain size is obtained for the lowest strain. At the lowest strains coarse carbide material has a longer incubation time and coarser Stage III grain size than the fine carbide alloy.
