Technical and economic target 1、利用系数Utilization ratio： Utilization ratio （t/m2 /h)＝Sinter output（t）÷active area（m2）÷realtime（h） 2、台时产量output of machine-hour： Yield of machine-hour （t）＝Output per hour per sintering machine 3、合格率Percent of pass： Percent of pass （％）＝Testing by quantity ÷Number of tests×100％。 4、alkalinity（R）： R2(binary）＝CaO/Si2O R3(ternary）＝（CaO+MgO）/SiO2 R4(quaternary）＝ CaO+MgO）/（SiO2+Al2O3) 5、consumable solid fuels（Kg/t）： consumable solid fuels （Kg/t）＝ consumable solid fuels total（butt）÷ Sinter output(t) 6、Process unit consumption （Kg of standard coal /t）： Process unit consumption ＝Net energy consumption process ÷ Sinter output 7、Equipment operation rate （％）： Equipment operation rate （％）＝ realtime （h）÷Calendar time （h）×100％ 8、Labor productivity （t/ person）： Labor productivity ＝ Sinter output(t) ÷Average number of employees * Technological flow process of sintering production Technical and economic target General for Sinter Plant Sinter is a process, that is to put different kinds of powdered iron contained raw material， mix into an amount of fuel as well as flux， put in an amount of water， pass through blending AND pellet formation,the material mixture be put into? sintering equipment, to make the material went on a series of physicochemical change， fine ore granule cementation to? lumpy process. TOP ENTER Technological flow process of sintering production : at present. linear? downdraught sintering machine is extensive useed in sinter ore production process. the technological flow process for sintering production as per the schech shown in chart. mostly include preparation of? sintering material, proportioning and blending，sinter as well as product treatment and others process.
