Iron ore, returned sinter, coke, limestone and dolomite are mixed to form the raw mix in the proportioning step. The raw mix is mixed with water in the mixing step to obtain the sinter material which is tiled on a sintering machine by the roller feeder. The sinter material is driven to an ignition furnace by the transmission device.

The MgO in blast furnace slag provides an optimum condition in terms of both good flowability and desulphurisation. The mode of its addition to the blast furnace changed from, initially, as raw flux in the form of dolomite, to via sinter, with the argument that raw flux demands energy for its decomposition inside the blast furnace.
Iron ore sintering is a crucial stage in the whole steelmaking flow, the function of which is to process iron ores (< 8 mm) into lumpy sinter, thereby providing raw materials for ironmaking [1,2,3,4,5]. The sintering heat originates from fuel combustion, either complete combustion or incomplete combustion.
Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace. ...

When iron ore deposits in the form of sinter are used for steel production, it is essential to monitor for homogenous sintering throughout the cake . The LWIR-640 thermal imager is our recommended solution.
In the sinter plant iron ore fines are agglomerated together with fluxes and iron-rich in-plant return fines to sinter. In the BF the iron oxides of the ore are reduced to metallic iron [1,2]. The BF is charged continuously from the top of the furnace in layers of iron-bearing materials (sinter, pellets, etc.) and coke.
An on-going challenge for sinter plants is to obtain higher productivity from their sinter blends, or maintain sinter productivity whilst using more financially attractive iron ores. One of the most effective means to reduced blend cost is to use a higher proportion of concentrated iron ores in the blend.
