A direct reduction furnace equipped reduction BLT-â… binding Rapid separation of iron slag reduction direct reduction technology antelope stone, Oolitic, titanium, iron ore and other hard gravel iron beneficiation of industrial production line successfully tested. Shenyang Bolian Special Technology Co., Ltd. developed its own smelting reduction of "direct reduction BLT-â… # reduction furnace equipment" after September, October, November, three consecutive tests, the use of the antelope stone Riverside, Jiangxi Oolitic, Indonesia laterite nickel ore, sulfuric acid residue Inner Mongolia, Shandong alumina red mud, iron oxide powder, Hakusan other raw materials, using a proprietary "DRI BLT-LS fast reduction process" and "DRI BLT rapid separation process," and the like directly The invention patent of reduced iron has succeeded in continuously producing high quality gravel iron. High-quality gravel iron products can be produced by using various refractory ore and easy ore dressing with original ore TFE=20-55%. Which indicators: TFe = 94-97%; MFe = 93-96%; ηFe = 97-99%, density of iron gravel ≥7.0t / m 3, ratio = 85-95% iron gravel. The project's process technology, equipment technology and high-quality product quality have been affirmed and supported by the leaders of the Jilin Provincial Party Committee and the Baishan Municipal Committee. The Jilin Provincial Party Committee has listed the comprehensive utilization of the Linjiang Antelope Stone Diffuse Concentration as the 12th Five-Year Plan of Jilin Province. planning. The "direct reduction BLT-I kiln equipment" integrates the advantages of the reduction kiln such as tunnel kiln, rotary hearth furnace and rotary kiln, and develops a new generation of coal -based direct reduction kiln equipment and technology in line with Chinese characteristics. Combined with the most advanced "direct reduction BLT-LS rapid reduction" and "direct reduction BLT separation rapid reduction process", "low grade ore, difficult ore, composite ore reduction and separation of gravel technology" process, all low grades can be hard mineral (iron stone antelope, oolitic), iron complex (vanadium and titanium magnetite, nickel laterite), iron-containing tailings chemicals (sulfuric acid residue, alumina, red mud, dust sludge, lead zinc slag) and other reduced iron is separated into gravel TFe≥90% or more high grade, high metal ratio of the metallic iron. Its main features: 1. Suitable for all kinds of iron-containing raw materials of high and low grade, especially suitable for the reduction and separation of gravel iron and metal iron powder of low-poor ore, refractory iron ore, composite iron ore box iron-containing chemical tailings. 2. No need to use expensive refractory tanks. 3. Compared with tunnel kiln method and rotary hearth method, the reduction speed is fast, the thickness of the cloth is thick, and the consumption of reducing agent is low (1/3 of the above two methods). 4. The product does not oxidize when it is reduced and does not oxidize twice during cooling. 5. The equipment is mechanized and the degree of automation is high. 6, you can use waste heat to generate electricity, fully realize the project self-sufficiency and have surplus. 7. The technology of high-density gravel iron will accelerate the pace of short-process steelmaking in China, especially the smelting of high-quality steel. 8. The use of gravel iron for short-process steelmaking will make due contributions to energy conservation and emission reduction. The application of this equipment and process technology will be at the forefront in the field of direct reduced iron in China's metallurgical industry and even in the world. Gravel iron product picture The series of machines using motor direct drive, high transmission efficiency; rotor by the balance of work, work smoothly; with the factory production of vertical mixer supporting the use of advanced performance, small footprint, low power consumption, easy operation and maintenance , Low noise and low dust pollution, widely applicable to small feed processing plants, livestock farms.
