摘要:
An object of the present invention is to provide a continuous galvanizing line with which a galvanized steel sheet having excellent zinc coatability can be steadily manufactured by preventing the oxidation of the surface of the steel sheet with certainty in an annealing furnace. A continuous galvanizing line having an annealing furnace of an all radiant tube heating type, the line consisting of a moisture removal device with which an atmospheric gas in the annealing furnace is collected and moisture is removed from the gas and then the gas is returned to the furnace, dew-point meters with which the dew-point of the atmospheric gas is observed, outlets through which the atmospheric gas in the furnace is collected and inlets through which the atmospheric gas from which moisture has been removed with the moisture removal device is fed into the furnace, the dew-point meters and the outlets being placed at least at two points which respectively exist on a side wall in the vicinity of the entrance of the annealing furnace and on a side wall in the vicinity of the furnace top or the furnace bottom at a position where a steel sheet has a maximum end-point temperature, the inlets being placed at two points which respectively exist on side walls on the sides opposite to the sides of the two points for the outlets in the height direction of the furnace, making it possible to steadily control the dew-point of the atmospheric gas to be -45°C or lower and -80°C or higher throughout the whole area of the annealing furnace.

A system for determining the phase envelope of a gas condensate includes a microfluidic device defining an entrance passageway, an exit passageway, and a microchannel in fluid communication with the passageways. The system includes an input sample bottle in fluid communication with the entrance passageway and a first pump associated with the input sample bottle for urging the gas condensate, in the input sample bottle, into the entrance passageway. The system further includes an output sample bottle in fluid communication with the exit passageway and a second pump associated with the output sample bottle for pressurizing the gas condensate, in the output sample bottle, into the exit passageway in opposition to the first pump. The system includes a temperature control device for controlling the temperature of the gas condensate in the microchannel. The first pump and the second pump operate to provide a desired pressure drop across the microchannel.

摘要:
Die Erfindung betrifft einen kapazitiv arbeitenden Sensor zur Detektion von Kondensation an Oberflächen. Bekannte kapazitiv arbeitende Sensoren (1) zur Detektion von Kondensation an Oberflächen weisen über eine den Kondensator bildende Metallschicht eine Passivierungsschicht sowie eine die Betauung (8) fördernde Zusatzschicht auf. In dieser Zusatzschicht sind Kondensationskeime integriert, an denen die Betauung (8) beginnt. Nachteilig ist, daß diese Betauung (8) tröpfenartig an den Kondensationskeimen erfolgt, wodurch die Empfindlichkeit des Sensors (1) minimiert wird. Demgegenüber wird die Oberfläche der Passivierungsschicht (6) hydrophil gemacht, wodurch eine Betauung (8) über die ganze Oberfläche der Passivierungsschicht (6) erfolgen und wahrgenommen werden kann.
