摘要:
The filter has a filtering chamber in which a number of hollow filtering elements are arranged on a circle about the axis of the filter. The chamber has a liquid inlet and a liquid outlet and the hollow filtering elements communicate in parallel with the inlet and outlet. A hollow arm defining a passageway is rotatable about the axis of the filter and the passageway is capable of putting all the inlets of the filtering elements successively in communication with an impurities discharging chamber in which prevails a pressure lower than the pressure of the filtered liquid. The arm is connected to rotate with the driven member of a unidirectional step-by-step drive mechanism. The arm is also connected to rotate with the driven member of a second unidirectional step-by-step drive mechanism in the same direction as with the first drive mechanism.
摘要:
In a method of deoxidizing and/or carburizing a metal, particularly steel, bath using an immersed nozzle consisting of two concentric tubes, the central tube of the nozzle is fed with an oxidizing gas during the or each oxidation phase, then with a scavenging gas, then with a neutral gas carrying carbon powder or powder containing carbon during the or each deoxidation or carburization phase and finally with a scavenging gas, the outer tube of the nozzle being fed with a protective fluid or different protective fluids during both the oxidation and deoxidation or carburization phases.
