Outotec® Steel Belt Sintering
The Outotec® Steel Belt Sintering (SBS) process brings smelting furnace efficiency to a whole new level. Benefits The use of sintered pellets makes smelting furnace Strict environmental limits can be achieved operations more stable and profitable. with small gas cleaning units and the
Pelletizing and sintering play a crucial role in effective recycling of cooling gases modifying the smelting behavior of ore since good Low operational costs charge uniformity results in consistent smelting Good and consistent pellet quality furnace performance, lower power costs and higher Pellets can be sold for other users as the recovery yields. pellets are strong enough to withstand Outotec Steel Belt Sintering is currently the most long transport distances efficient and profitable solution available for chromite ore and niobium ore pelletizing. It can also be adapted to handle iron ore, manganese ore, nickel ore and steel plant dust. Outotec Steel Belt Sintering Furnace energy consumption is very low. The efficient utilization of CO-rich off-gas from the smelting furnace further The Outotec Steel Belt Sintering Furnace is an increases total savings. effective, multi-compartment oven through which pellets are conveyed on a perforated steel belt. This Solve your fines problem by sintering them treatment gives the pellets a strong structure that can into profitable pellets withstand mechanical and thermal treatment. Since the cooling gases are efficiently utilized in the front- The primary raw materials in the steel belt sintering end compartments for drying, heating and sintering process are ore fines and/or concentrates, as well as purposes, the steel belt sintering furnace's external fine coke. These feed materials are ground in a ball mill, de-watered in capillary-effect ceramic filters and pelletized in a drum before finally being sintered in the steel belt sintering furnace. Technical specifications for the Outotec® Steel Belt Sintering Furnace The end products are spherical, uniformly sized, hard and porous pellets with consistent physical Design capacity 300 000 – 700 000 tpa and chemical properties. They are an ideal charging Total length 30 – 45 m material for ferroalloy smelting in the Outotec® Belt width 4 – 6 m Submerged Arc Furnace. External energy 150 – 250 kWh/t consumption Technological breakthrough
Total electric energy consumption in 50 – 80 kWh/t product The Outotec Steel Belt Sintering Furnace, which Outotec SBS Plant consists of multiple compartments, is designed to Green pellet feed 50 – 110 t/h optimize output. The counter-current flow of cooling gases carries waste heat from finished pellets to Temperature in sintering 1300 –1400 °C compartment those entering the front-end compartments. Due to the highly efficient use of cooling gases in the front-end 100 000 – 250 000 Nm3/h Off-gases total 50 – 150 °C compartments and low exhaust gas temperatures, the external energy consumption in the sintering furnace Cooling airs total 100 000 – 250 000 Nm3/h is very low. The exhaust gas flows are minimal and are Sintered product pellets 45 – 90 t/h cleaned in the Outotec® Cascade Scrubbers. Plant dust is effectively recycled back to the pelletizing process. Outotec® Ferrochrome Process
The most profitable ferrochrome Benefits of high-quality pellets for ferroalloy production concept on the market smelting in a closed furnace:
The structure of the Outotec® Ferrochrome Process nn Increased recovery combined with state-of-the-art process control nn Better furnace operation systems guarantee high availability and reliable nn Higher average load and power factors operations, as well as a clean working environment. nn Significantly lower energy consumption nn Continuous and consistent operation In addition, the low energy consumption, small nn High furnace availability process gas volumes that are circulated for maximum nn Ability to use low-cost fines energy recovery and closed process water circulation nn Increased production with the option of also make our ferrochrome process attractive from preheating the furnace charge in an environmental perspective. This is why the Outotec the Outotec® Preheating Kiln Ferrochrome Process is considered an industry nn Up to 20% increased capacity from benchmark and Best Available Technique (BAT). your smelting furnaces Copyright ©2014 Outotec Oyj.Allrightsreserved. www.outotec.com [email protected] Outotec Furnace Charge Co., Ltd., Co., China Charge Furnace Taigang & Shanxi TISCO Wanbang Arabia Saudi Cristal, Owner Tubatse Ferrochrome, South Africa South Tubatse Ferrochrome, Samancor Chrome Ltd, China Ltd., Co., Mintal Group Ferrochrome, South Africa South Ferrochrome, Samancor Chrome Ltd, Middelburg Outokumpu Chrome Oy, Finland Oy, Chrome Outokumpu Ferrometals, South Africa South Ferrometals, Samancor Chrome Ltd, Kazakhstan Kazchrome, TNK AO Africa South Ltd, (Pty) Ferrochrome Hernic Africa South Ltd, (Pty) (SA) Metals International Ferro Smelter,Wonderkop Africa South Venture, Merafe Glencore Kazakhstan Kazchrome, TNK AO Africa South Ltd, (Pty) Metals Asa France France, Manganese Glencore Rustenburg Smelter,Rustenburg Africa South Venture, Merafe Glencore Boshoek Smelter, SouthAfrica Glencore Merafe Venture, (Pty) Ltd, South Africa South Ltd, (Pty) (SA) Metals International Ferro ® Steel Belt Sintering (SBS) Plants and Outotec and (SBS) Steel Sintering Belt Plants Outotec provides leading technologies and for services the sustainable use of Earth’s natural resources.
