Regenerated black Silicon Carbide, 52 SRB

ККЧ 52 СРБ

Regenerated black Silicon Carbide (SiC) 52 SRB produced by the method of regeneration recycling of abrasive tool of black Silicon Carbide of 54 C grade on bakelite binder.

The essence of regeneration recycling process consists in reconditioning of waste materials for the purpose of reclaiming this material in production.

All technological processes of regeneration are implemented with use of own equipment by qualified personnel.

The production complies with normative document ОСТ 2 МТ 79-3-88 or technical requirements of the Customer.

Technical parameters of SiC 52 SRB:

1. Chemical indicators, %:

SiC Cfree Fe2O3
92,0 – 94,0 0,6 – 0,8 0,5 – 0,7

2. Technical indicators:

Relative density, g/cm3 3,15 – 3,25
Bulk weight (depending on grain size), g/cm3 1,31 – 1,40
Melting point, °C 2730
Mohs hardness 9

3. Grain size (fraction):

Grain size (particle size range) of the output is determined individually by customer at step of forming an order and may correspond to FEPA standard, ISO 8486-1.2:1996 and ГОСТ 3647-80.

Main produced fractions of SiC 52 SRB
-2,0 / +1,0 mm -1,0 / +0,5 mm -0,5 / +0,0 mm

4. Toxicity:

Regenerated black Silicon Carbide (SiC) 52 SRB isn’t dangerous for health. Its use doesn’t cause with a danger of silicosis. Regenerated Brown Fused Alumina 12 АRB is neither carcinogenic nor toxic.

5. Packaging:

The main type of packaging is flexible intermediate bulk container (Big Bag) either coated or uncoated – by Customer’s wish.

Production may also be packed into coated polypropylene bags weighed 25 -30 kg.

The average weight of big bag with production is 1,5 ton.

6. Application:

  • for production of abrasive tool of the black Silicon Carbide;
  • for production of refractory fired products with SiC content and concrete mixtures;
  • for sandblast machining of surfaces;
  • for fire-brick lining of sand (dredging) pumps;
  • as deoxidizer for steel, instead ferrosilicon FS 25, FS 45.
