ABSTRACT:
Apparatus for physically or chemically treating a substance in a vessel under conditions which make it difficult to ascertain physical and/or chemical changes, comprising means for monitoring the weight of the substance in the vessel and producing a signal indicative of the apparent variations in weight of the substance, which signal includes, as a factor, a variation in weight due to agitation of the substance in the vessel as it undergoes a physical and/or a chemical change, means for extracting and recording that part of the electrical signal produced by the agitation of the substance as a function of time, whereby the treatment of the substance may be altered in accordance with the signal produced by the agitation. When the substance is a molten charge in a steel making process involving the injection of oxygen, the part of the signal produced by the agitation of the molten charge is a frequency band within the range 0.05Hz to 0.5 Hz.
