High-quality high-alumina refining slag prices - export prices high alumina refining slag ingredients by optimizing processes, innovative charging structure, explore charging system, the successful application of polycyclic cloth, research performance aluminous slag smelting technology to master the high bauxite, the successful implementation of high air temperature, high top pressure, high coal ratio, low silicon smelting technology, in charge lower grade coke quality dog ??magnitude lower case, and achieved good economic results. In the selection of economic ore smelting, we must face some unfavorable economic factors brought mine, where ore high Al2O3, is a prominent problem. Al2O3 slag is generally believed that within 14%, a low-aluminum slag, suitable for smelting; 14% to 16% are in aluminum slag, smelting have some difficulty; Al2O3 more than 16%, it can be called high-alumina slag smelting quite difficult . Many companies even believe that above 17% after the basic can not be normal smelting. Through in-depth study of the properties of high aluminum slag, basic grasp of the aluminous slag smelting technology. Japanese steel slag lowest Al2O3 content are more than 15.5%, the highest average of more than 18%, are high aluminum smelting slag. Al2O3 more than 16%, will be a sharp rise in the slag above the melting temperature to 1500oC, the slag viscosity will increase. Slag viscosity is too large, slag viscosity, it will cause a loss of blast resistance band dropped greatly, resulting in decreased burden and gas increased difficulties. In the hearth difficult to separate the performance of iron slag, iron slag holdup increased accumulation of hearth; performance outside the furnace slag and iron crusts, poor flow properties, Front organizational difficulties; and finally, the ability to be getting worse by the wind blast resulting blast disorders. For high aluminum slag viscosity is high, the problem of high melting temperature of the slag system and thermal regime of high aluminum ore smelting readjusted, slagging system should determine the binary alkalinity as the main means of regulation, as the ternary alkalinity reference, four yuan total alkalinity centric approach and proposed Mg-Al ratio (MgO / Al2O3,) concept. By adjusting the pH alkalinity binary material, reference Al2O3 content in slag by adjusting the sinter MgO, MgO content of the slag control, with the Al2O3 content in control than Mg, Al, and finally four no slag basicity control 0.95 to 1.0 or so. Thermal systems to control the sensible heat of molten iron as the basis of daily transfers to control the amount of iron in silicon as a means to ensure the physical temperature molten iron ≥l480oC, and ultimately to improve the enthalpy slag, reduce slag viscosity, improve mobility slag day, effectively improve the working condition of the hearth, improved blast along the line, and achieved good results. Low silicon smelting is an integrated technology. Since the original fuel conditions gradually slip on steel, low silicon smelting can not rely on improving the quality of coke, to improve the grade into the furnace and other "concentrate" means to achieve. The difficulties faced by the ironmaking technology personnel, were fully analyzed by the iron front of the lead organization, research meetings held regularly every ten days for sintering, pelletizing, iron three systems, emphasizing the low silicon smelting of iron significance of steelmaking, while emphasizing the internal system and reduce silicon from the start, to be fully operational by raising the level to guarantee the realization of low silicon smelting.
