An investigation on optimum grinding system and conditions for steel plant ARP by-product α-Fe2O3 for pigment industry
(Elsevier, 2020)
After some other processes, α-Fe2O3 red powder particles -by-product of regeneration of spent pickling liquor in ARP in iron and steel industry- should be ground up to pigment grade to convert it to a value added product, ...
Microabrasion Wear Behavior of Fast-Borided Steel Tooth Drill Bits
(Taylor and Francis Inc., 2017)
In this study, the surface of steel tooth drill bits (Ni-Cr-Mo based) was subjected to the solid-state boriding treatment with 10- to 50-nm nanoboron powder. Boriding processes were carried out at a constant temperature ...
