| Continuous Measuring of Heat Pattern in Sintering Bed and Its Application to Sintering Operation

Synopsis : In order to raise the productivity of sinter and to control its quality, it is important to grasp the characteristic of the combustion zone in the sintering bed. A heat pattern measuring apparatus recently developed permits a continuous measurement of about 25 heat pattern cycles. It consists of three parts, i.e., a metal-sheathed thermocouple, its protector and telemetry equipment. From a heat pattern obtained by this apparatus, two indexes, Q value and CT value, are calculated. The Q value is estimated by an integration temperature curve above 900, and CT value by the cooling rate from peak to 1100. Results so far obtained through the use of the apparatus are summarized below. (1) A correlation is found between the Q value and shatter strength. (2) A simple correlation is found between FeO content in sinter and the CT value or peak temperature in the sintering bed. |
