Sintering is an important step in steel production. It involves fusing togetherraw materials, such as iron ore, coke and limestone, at a high temperature and then converting the fused mass into steel. There are approximately 150 sinter plants around the globe. Having a more consistent sinter product and ensuring its quality is crucial to steelmaking, so steel companies analyze the sintering process to make sure it is …
