Theory And Practice Of Limonite Replacing Traditional Concentrate Powder

Since the establishment of the plant in 2006,our sintering team has been committed to the study of how to give full play to the production capacity of equipment,analyze the internal problems through benchmarking with the same industry,and introduce new technologies and methods with the development of science and technology.Improve the production environment of sintering machines.We will increase production and reduce overall energy consumption.Since 2008,the domestic steel industry has ushered in a cold winter.The price of domestic concentrate powder has remained high,and the imported limonite has a clear price advantage.In order to reduce the cost of steel production,It has become an inevitable trend to replace domestic concentrate powder with limonite,so the ratio of domestic concentrate powder is reduced.Therefore,an experimental study was made on the substitution of limonite for concentrate powder.In order to adapt to the large proportion of limonite,the factory has done a lot of work from the following aspects,and has achieved gratifying results.First,the preparation of raw materials,there is no condition to establish a comprehensive material field,using the existing site conditions,as far as possible to achieve Silicon storage;Second,in order to improve the accuracy of automatic weight ingredients,the most advanced ingredients scale is adopted in the world;The third is to improve the granulation effect by reforming the inner drum of the mixing machine;The fourth is the change of cloth style;The fifth is that the igniter adopts a new type of gas air double Preheat ignition technology;The sixth is to change the original design of the sintering machine to limit the thickness of the material layer and increase the height of the sintering machine platform.Seventh,in order to increase the effective wind volume,a series of measures to increase the wind volume to reduce the leakage of wind.Figure 9;Table 23;Participation 44 articles.
