The economic assessment shows that the use of silicon carbide in the massive production, Costs related to the ino culating operations reduced by 36% . 5. CONCLUSION The results of the evaluation of silicon carbide as latest inoculants shows that decreased the amount of silicon carbide to 0.15%wt, increased Percent pearlite phase.
Jun 02, 2017· Silicon carbide will indeed grind carbide tooling, but it more crules the edge than sharpens it. You will be messing with a diamond lap for a long time getting the tool sharp after roughing it with a silicon carbide wheel. Your angle grinder diamond wheel will work, and you can mount the grinder rigidly and make a simple rest for the tool.
