A new method for evaluating the melting performance of the slag

ABSTRACT Aiming at the shortcomings of traditional slag use of height to represent melting temperature, the melting performance of desulfurization slag under different binary alkalinity is tested, and any time image in the melting process is binarized to obtain the realtime area of slag heating and melting process.The area change rate is obtained from the real-time area and the initial area, and the melting performance of the slag is evaluated by the area change rate. The results show that using the change of the whole area of the slag instead of the change of the height to evaluate the melting performance of the slag can comprehensively evaluate the melting process of the slag, which not only improves the accuracy and universality of the evaluation of the melting performance of the slag but also shows the change rule of the low-temperature slag expansion process.
