BF Size of SSIT's Supply(effective volume): 320m3-3400 m3
Modern Features of BF supplied by SSIT:
1- Long Campaign Life: Ceramic cup plus carbon blocks underhearth as well as reliable proper cooling system make it possible for BF life to be more than 15 years.
2- Thin Furnace Wall: stave cooler with insertion refractory lining, increases the furnace volume without compromising the cooling effect.
3- Bell Less Top: reliable sealing and flexible distribution, bringing about a sound charging and furnace top gas system.
4- Soft Water Closed Circuit Circulation Cooling: strong cooling effects, creating favorable conditions for a longer campaign life of blast furnace.
5- Tangential Top Fired Stove with Ceramic Burner as well as Combustion Air & BF Gas Double Pre-heating System: easily achieve 1150-1200 degree Centigrade blast temperature. Oxygen enrichment rate: 3-5%.
6- Flat Cast House: allows free movement of the cast house vehicles in the cast house and a ramp is also designed to connect the cast house to the tuyere platform for convenient movement between the cast house and the tuyere platform.
7- Top Pressure Recovery Turbine (TRT): vividly called MONEY PRINTER, making use of the BF gas pressure for power generation.
8- Pulverized Coal Injection (PCI): injection rate up to 200kg/t•hot metal with reliable safety measures.
9- Dry Type Gas Cleaning Plant (Bag Filter): no water consumption or sewage emission, high gas temperature and superior gas quality, power saving, minimal land occupancy, low investment, etc.
10- Screw Conveyor Type Slag Granulation Plant (latest generation of slag granulation technology): highest automation level slag granulation technology available at present, environment friendly, energy efficient, least construction space, less investment, easy operation and maintenance.
