It also means the optimized value of the stress drop, 64 bars, is a reliable estimate for the mainshock of the 2016 Kumamoto earthquake, because the stress drop controls the spectral amplitude of high-frequency part (Motazedian and Atkinson 2005).
Before inversion, when the viscosity of the oil is 0.025 N s m−2, drop diameter, Dowo, is given by Dowo = 0.08 exp (5fw/2) N−0.8 indicating that drop coalescence controls drop size.
In particular, edge drop control by optimizing the roll profile has become a popular research topic.
The edge drop control technology can reduce the cutting loss and increase the yield.
The research achievements of edge drop control technology are mainly embodied in developing automatic control systems and designing roll profiles.
The most advanced edge drop control technology at present is the K-WRS technology of the 6-high UCMW cold rolling mill.
This development indicates that the edge drop control technology of the 6-high UCMW cold rolling mill has matured.
The application of edge drop control technology to silicon steel has received increasing attention in recent years.
Sun, et al. [80], adopted a single-side straight-taper work roll profile to enhance the edge drop control capacity of the 6-high UCM rolling mill.
