The intrinsic frequency of a beaker can be determined by means of direct determination,resonance or water drip modulation,and each of the methods makes use of the Lissajous figure.

Laboratory experiments are carried out in a sintering pot to simulate sintering machine,so that the influence of capacity expansion of sintering machine on the FeO content and drum index of sinter is studied.

On the basis of sinter pot test,an industrial experiment of adding SYP sintering synergist was carried out in No.

The main features of the newly manufactured sinter pot test systems in our country were summarized,and their performance figures and progress in design of the main equipments in these systems are introduced in this paper.

This paper gives an introduction to the hardware and software configuration of the sinter pot test supervisorysystem,the sinter pot test supervisory system based on S7-300PLC and WinCC soft is described in detail.
