2 One of the world's giant iron-rich deposits.
The main iron ore production company in Brazil is Dosi Valley 1 Sian United Mining. 1 Charges Tanco 61.0, Samaku 13131. 0 and 1! . Miguo 53. The company is the largest iron ore production company in Brazil and the world. In 1999, iron ore sales were 93.1 million, and exports were 80.2 million. Of which, 7.3 million were exported to China. The company is the first person to produce iron ore in Brazil. In 1999, it produced 1 iron ore of 20.7 million 1616. The company exports 1 million of iron ore every year, while 1 commits 0 and 330. The company exports 40. 31; The company's iron ore is exported using its own port. The 51. Gong 4 transports the pellet powder to the pellet factory located in the lane through Nong Road to produce pellets and transport the products to all parts of the world. The iron ore products produced by the Caracas Mine through the port of Matila include ordinary sintered lumps, high-manganese ore concentrate powders, and pellet powders. Iron ores generally have high iron grades and contain little silicon oxide and aluminum oxide. The sintering performance is very good and the Brazilian iron ore resources have the advantages of concentrated distribution, large reserves, and good port installation conditions. Therefore, it has great appeal to many steel plants in the world. Because Europe is close to Brazil and has low shipping costs, most of the high-quality Brazilian iron ore is exported to European steel mills. While Asia is farther away from Brazil, the CIF of imported Brazilian iron ore is higher in Asia. Although the ratio of Brazilian ore in the mixed ore and the performance of sintered ore have been greatly improved over time, the cost of raw materials is added to the current Steel production is constantly in conflict with the goal of low cost, so Asian countries are constantly developing new sintering technologies, using less expensive Brazilian mines and more low-cost mines.
4 Conclusion Raw materials not only determine the quality of the final product, but also determine the effective use of the iron ore resources of the final product, which is the premise of high-quality and low-cost production in the steel industry. It is still iron ore, while the production of electric furnace steel in Japan and the United States has reached 31 and 46, respectively. The Guan 2000, 771.3 Jiao Yushu.

The successful production of Magang's steel slab caster was put into production. After a half-month trial operation of heat load, the main supporting project of Magang's flat conversion project was formally put into operation on August 28, 2001, which marked the production In the adjustment of product structure, another big step forward was taken, which laid a reliable foundation for the company's steelmaking full continuous casting.
The company's steel slab continuous casting machine project has a total investment of 100 million yuan and an annual output of 700,000 slabs; the production specification is 15022025010001400, fixed length 7, drawn into ± jade steel grades can be adapted to low; For bridge boilers, pressure vessels, etc., casting and casting machines need to be based on domestic design and manufacture, and the necessary stand-alone equipment and supporting bodies are introduced. Its technical performance and machine equipment are at the domestic advanced level. The installation work of engineering construction equipment was delivered to Ni Jialin by Ma Steel
