Laboratory pot grate ntering experimentation has been carried out to study the effect of HMDS Slag addition on sinter productivity, and physical and metallurgical properties. The HMDS Slag in the sinter mix was varied from 0 to 60kgt of sinter.
Oct 20, 2016 Sat process plant for iron ore sinter . The iron ore sintering process prepares fine iron the ores for the blast furnace process. sinter plants agglomerate iron ore fines with other fine materials at high temperature in a mix bed to create a product that can be used in a blast furnace. main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux.
due to its abundance in iron ore sinter and its significant influence on sinter quality, sintering reactions have specifically been studied with regard to the control of the concentration and microstructure of the SFCA phase that forms during the sintering process 3,4. The volume of the melting phase plays a significant role during sintering.
Jul 01, 2020 Sintering is the most extensively used and economic agglomeration process to prepare iron ore fines for blast furnace use. Granulation is the most critical factor controlling iron ore sintering process, as it improves sinter mix permeability. Currently, sinter plants are receiving significant proportion up to 40 of 150 m micro-fines in iron ore fines, which makes sintering difficult.

Non-uniformity in the bed composition. 3.3 Role of Sinter Plant The function of the Sinter Plant is to supply the blast furnaces with sinter, combination of blended ores, fluxes and coke, which is partially cooked or sintered.
Jan 16, 2018 35 . The granulometry of iron ore fines, used in sintering, has a great influence on sinter plant performance. Laboratory Experiments were conducted with different granulometry of iron ore fines to assess its influence on sinter quality and productivity. The upper size of the iron ore fines was reduced in each of the experiments.
