Filed: 1974-06-14
Abstract: 1432108 Automatic temperature control BLOOM ENG CO Inc 14 June 1974. [15 June 1973] 26560/74 Heading G3R As a workpiece 16 passes horizontally through a furnace 10 between upper and lower heated zones 13 and 14, the temperature of a workpiece surface in one of the two zones is sensed by means 17 such as a radiation pyrometer whose output controls the heat input to both zones. As shown, the temperature of the lower surface, in zone 14, is sensed and used to control the lower zone heat controller 22 directly. The same temperature signal is fed to the upper zone heat controller 24 via a unit 26 whose function is so to modify the input as to maintain a required relationship (e.g. a fixed difference) between the temperatures of the two zones. The invention is described with respect to the case in which the workpieces are slabs or billets passing between upper and lower pre-heat zones 11, 12 via the above mentioned zones 13, 14 on to a 'soak' zone 15 and thence to a rolling mill. Unspecified means associated with the mill may be used to provide a signal 38 which, through a unit 32, introduces a delay which modifies the control. The output elements 28, 30 are motors which in turn actuate air and/or fuel valves of the furnace.
