Sintering Machine Dilatancy Transformation And Thick Material Level Low Temperature Agglutination Craft Analysis

Since1990s, the domestic steel and iron output swift and violent increase, the blast furnace to the large scale development, the integrated iron and steel works old blast furnace and the multi-place small blast furnace is substituted for by the large-scale blast furnace, makes the agglutination productivity lag in the iron-smelting ability, the agglomerate output also correspondingly to increase, the partial enterprises chose have earied on the dilatancy transformation to the existing sintering machine the means to obtain the success, this article have carried on the dilatancy transformation to the Tianjin Iron and steel company Ironworks265m2sintering machine to increase the agglomerate output. After the transformation, considered factors and so on time limit for a project, location, investment and demand, finally determined the265m2sintering machine convulsion area by the265m2dilatancy to300m2, the sintering machine length is invariable, the trolley width widens by4m to4.5m, the fence board increases highly by original650mm to750mm, the main drawing fan amount of wind increases by12000m3/min to20000m3/min, and correspondingly to the leather belt system, one, two cylinder mixer, the sintering machine main body, the single roll breaker, link Leng Ji, the dust removal system and other system-relateds has carried on the transformation.In the agglutination craft progress, the agglutination is developing fast along the thick material level slow engine speed direction, in addition raw material condition change, the outsourcing high-grade ore proportion increase, the agglutination negative pressure is lower than the original design far, has created the precondition for the thick material level transformation.In addition original equipment aging, also needs to run to two fever workshop sintering machine trolley waits for the question all to need to transform the overhaul.In order to reduce the sintering circuit energy consumption and the improvement agglomerate intensity, mainly enhances the trolley fence board from original650mm to750mm, for achieved enhances the material level the final goal, needs to carry on the necessary system the transformation, in which for enhances the agglutination blend temperature, increases the steel putty to fetch water the system, replaces the mixer the backing to strengthen the mix to make the ball effect, the improvement agglutination blend size composition. After the transformation265m2sintering machine main parameter change is very big, for causes the sintering machine to reach as soon as possible produces, has carried on a series of agglutination cup experiment, the commercial test, and actual carries on the summary and the analysis to the experiment, discussed about the thick material level bottom warm agglutination rationality and the measure.Through analyzes the265m2sintering machine the transformation andthe thick material level low temperature agglutination attack, has provided the theory basis for the next other sintering machine transformation.The sintering machine achieved and surpasses the design level, each parameter obtains the comprehensive optimization.Has met the actual production needs.
