Improving resource utilization efficiency:The return ore pressing technology can turn the by-products generated in the steel production process,such as small-sized sintered ore and blast furnace dust,into pellets through cold pressing technology,achieving environmentally friendly and rational utilization of these by-products
Reduce energy consumption and emissions:Compared with traditional sintering processes,the return ore cold pressing pellet technology does not require high-temperature treatment,which can significantly reduce energy consumption and pollutant emissions such as SO2,NOx,etc
Improving the burden structure of blast furnace:Cold pressed pellets can replace some sintered ore and pellet ore,increase the clinker ratio of blast furnace,and facilitate stable and smooth production of blast furnace
Improving the quality and grade of sintered ore:Cold pressed pellet technology for returning ore can help improve the quality and grade of sintered ore,and enhance its metallurgical properties
Reduce production costs:Using recycled cold pressed pellets can reduce fuel consumption during sintering and lower production costs
Reduce cycle re firing:Cold pressed pellet technology for returning ore can avoid the"big cycle"of sintering returning ore,reduce dependence on the sintering system,and release sintering capacity
Improving the compressive strength of sintered ore:The pellets produced by the cold pressed pellet technology have high cold compressive strength,usually above 2500N,which meets the requirements of blast furnaces
Promoting environmental protection and social responsibility:Reasonably utilizing by-products,reducing waste emissions,improving corporate environment,and reflecting corporate social responsibility
Reduce carbon emissions:Cold pressed pellet technology for returning ore can reduce carbon emissions.Compared to sintering production,the carbon emissions of cold pressed pellets for returning ore are lower
Improving economic efficiency:Through the technology of cold pressing pellets for returning ore,steel enterprises can directly increase sintering output,reduce costs,and improve economic efficiency
