A coating control system is provided enabling continuous operations, free of interruption for coating control purposes, while achieving desired coating weight and thickness profile for the various gages, widths and coating specifications encountered on a given continuous strip production line. In each of a pair of elongated pneumatic dies, a pressurized gas jet is controllably shaped and directed by flow-control means internally-mounted of each pneumatic die to impinge against its respective substrate coated surface with its major directional component of force being controlled to be perpendicularly transverse to the travel path of the coated strip across its full width. Adjustment of such internally-mounted means is coordinated with control of gas pressure supply and/or adjustment of die positioning means to maintain desired coating weight and coating profile across the width of the strip. Pneumatic and other crown-control measures of the invention are exercised along the centerline of the of the strip enabling production of continuous-strip galvanized steel product having improved tracking and handling properties.

Method and apparatus are disclosed for accurately controlling the temperature of a moving metal strip in a continuous heat treating operation. A plurality of temperature sensors are located at fixed intervals along the path of the metal strip through the heat treating apparatus, e. g. , the cooling tunnel following an annealing oven, employed to control the application or extraction of heat and thereby the rate of temperature change of the strip. Errors in sensor readings are compensated by secondary averaging of adjacent temperature differential measurements to provide a more accurate temperature control.

A method of and system for controlling the oil concentration in and the stability of an oil-in-water emulsion used as a coolant-lubricant in a metalworking operation in which a portion of the emulsion is circulated through a sensor to monitor its density and to generate a signal relating the density to the oil concentration. The signal is employed to control addition of oil to the emulsion to thereby control the concentration within close limits. Sensing means also monitors the stability of the circulated emulsion, and emulsifier is added, as required, either to the oil to be added or directly to the emulsion to thereby control both the oil concentration in and the stability of the emulsion.
