Estimation of burn-through point in the sinter process

In sintering process, the operator determined the sinter pallet´s speed based on the location of BTP. Therefore, it is important to estimate the BTP so that the reliability is high. Quadratic curve was inferred by the curve fitting about wind box with the highest temperature and the sides of the wind box in previous studies. This allows, BTP was estimated. However, this is a disadvantage the correlation coefficient is small where except for the three points. In this paper, wind box is reflected from 17 up to 25, and wind box with the highest temperature and the sides of the wind box are added in range of curve fitting. This was fitted the cubic and fifth-order curve. BTP were estimated in this condition is similar to the actual temperature curve.
