Abstract
The basicity, i.e. the CaO/SiO2 ratio, of a sintered iron ore is controlled automatically by passing a stream of raw material consisting of a mixture of iron ore and fuel past a sampling point at which a sample of the ore is taken and the basicity determined to a location at which limestone is continuously added to the raw material control signals being generated in the process to represent the basicity determined for the sample, the amount of material between the sampling point and the limestone addition point, and the rate at which the raw material is being delivered at the addition point, which signals are fed into a computer which then computes the amount of limestone addition necessary to achieve a desired basicity and initiates a control signal to the limestone adding mechanism so that the correct amount of limestone is added to the raw material which has been sampled so as to achieve the desired basicity in the ore before it is subjected to a subsequent sintering step. The raw material mix may be collected in a reservoir prior to the addition of limestone, when the computer is provided from appropriate sensing devices with signals representing the amount of material in the reservoir when a given sample was taken, and the rate at which material is being withdrawn from the reservoir for use. With this information, together with a signal representing the basicity determined for the sample, preferably by X-ray fluorescence, the computer is able to control the limestone addition mechanism so that there is added to the raw material stream just that amount of limestone necessary to give a desired basicity to the ore passing at that time through the limestone addition point. The stream is subsequently passed through a mixer and then sintered. If desired after mixing, in the limestone, the basicity is again determined, compared with the desired value and any necessary adjustment made to the mixture before it is passed to the sintering step.
