Temperature Monitoring in Primary Metals Processing

Sinter Plant

A sinter plant can process various materials into a finished product that has the desired chemical composition and grain size to be used in the blast furnace. Materials include iron ore fines, limestone, dolomite and waste dust, scale and slag particles. The mixture of materials are baked on a moving conveyor, ignited by burners from above with fumes extracted from below, which ensures complete baking from top to bottom. At the end of the line, the "sinter cake" is discharged onto a "crash deck" for crushing and cooling.

Application Need 

During the sinter process, there is a need to ensure homogeneity in the burning section and measure core temperature after baking. It is important to avoid costly damage of conveyer belts and over quenching of the finished product.
