Swelling Index Of Iron Ore Pellets

gb/t 13240-2018 pdf english. - chinese standard,iron ore pellets for blast furnace feedstocks--determination of the free-swelling index: sector / industry: national standard (recommended) classification of chinese standard: d31: classification of international standard: 73.060.10: word count estimation: 16,165: date of issue: 2018-05-14: date of implementation: 2019-02-01: older standard (superseded by this standard).swelling behavior of iron ore pellet reduced by h2–co,volume swelling of iron ore pellets accompanied with strength decrease appears commonly during reduction. in order to ensure permeability and operation in shaft furnace smelting processes, the maximum swelling index of pellet is always required to be no more than 20% , . numerous researches have been done to reveal the swelling behavior of iron ore pellets..iron ore pelletizing process: an overview | intechopen,the final use of iron ore pellets in ironmaking reactors requires minimum mechanical properties. pellets must withstand tumbling and falling during transport and mechanical loading inside the reactors due to the charge weight. in order to increase its mechanical strength, green pellets are thermally treated in the induration process..iron ore pelletizing process: an overview,the iron ore pelletizing process consists of three main steps: 1. pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2..
