Chemical analysis
1,Chemical contents should meet the following requirement |
Size distribution | SiC >=(%) | FC <=(%) | Fe2O3%<= (%) |
Black silicon carbide | 12#-90# | 98.5 | 0.2 | 0.6 |
100#-180# | 98 | 0.3 | 0.8 |
220#-240# | 97 | 0.3 | 1.2 |
Green silicon carbide | 20#-90# | 99 | 0.2 | 0.2 |
100#-80# | 98.5 | 0.25 | 0.5 |
220#-240# | 97.5 | 0.25 | 0.7 |
W63-W20 | 97 | 0.3 | 0.7 |
W14-W10 | 95.5 | 0.3 | 0.7 |
W7-W5 | 94 | 0.3 | 0.7 |
2,Density:46# green silicon carbide <=3.18g/cm^3.Black silicon carbide>=3.12g/cm3”. 3,Grit size and grit size distribution should meet regulations on GB2477-83(Grit size and its distribution)4,Ferroalloy particles :30# and any lower number have zero particle if does not go through 45# sieve;36# to 90# have zero particle if go through lowest level sieve; 100# and any higher number have zero particle if does not go through mixed grain lower level sieve. 5,Magnetic:magnetic content of 12# to 240# should be less or equal to 0.20%. |
