Specular reflectance values at 85 deg illumination were calculated from the surface roughness calculated data. Based on these calculations, a series of large particle size monodispersed emulsion polymers was prepared using Ugelatad polymerization techniques and evaluated for their surface altering effects in...
In the finish rolling after the heat retaining, the final pass is executed preferably at <=950 deg.C at >=20% draft. By increasing the amt. of its austenitic phase in the process of the hot rolling, a hot rolling texture formed in its ferritic phase can be destroyed, and the ...
