摘要： There is provided a dual stage ceramic foam molten metal filtration system and method. Coarse and fine filters are mounted adjacent to one another in a molten metal flow path. A convection preheat apparatus provides preheat for both filters. A vent structure is included to vent air which may be trapped in a gap which is formed between the two filters.

摘要： There is provided an improved radiant burner formed from a reticulated ceramic substrate. The porosity of the substrate is such as to permit combustible gas to pass therethrough. The substrate includes a plurality of intersecting grooves extending into one of its surfaces, thereby substantially eliminating cold spots on the radiant burner.

摘要： There is provided a method and apparatus for removing liquid salts from liquid metal utilizing at least one porous substrate which is wettable by liquid salts and is not wettable by liquid metal. The porous substrate is inserted into a container having a quantity of liquid metal which is contaminated with an amount of liquid salt. The salt contaminated liquid metal contacts the substrate so that the liquid salt is absorbed into the porous substrate. The salt wetted porous substrate is then removed from the container.
摘要翻译：提供一种利用至少一种多孔基材从液态金属中除去液态盐的方法和装置，该多孔基材可被液体盐润湿并且不被液态金属润湿。将多孔基材插入具有液体金属量的容器中，该液体金属被一定量的液态盐污染。盐污染的液体金属与基底接触，使得液态盐被吸收到多孔基底中。然后将盐润湿的多孔基材从容器中取出。

摘要： There is provided an apparatus and method for detecting molten salt in molten metal. A pair of electrically conductive probes are immersed in the molten metal. The probes are connected to an electrical circuit which includes a voltage source and a current detector. The entire immersed portion of one of the probes is coated with an electrically nonconductive porous material which is wetted by molten salt but is not wetted by molten metal. If molten salt is present, the circuit will be completed and a substantial electrical current will flow between the probes, which current is detected by the current detector. If no salt is present, the circuit will not be completed and essentially zero current will be detected.

摘要： There is provided a composite ceramic foam filter having an outer edge which is surrounded by a protective sleeve, with the outer edge of the filter being bonded to the inner surface of the sleeve. The composite is preferably made by forming a ceramic sleeve having an opening therein, and forming a ceramic foam filter of a size and shape to fit the opening in the sleeve; placing the filter into the sleeve opening thereby forming a composite; and drying and firing the composite thereby bonding the filter to the sleeve, resulting in a single piece. Alternatively, a dried foam filter could be placed into the opening of an unfired sleeve and the two pieces are then fired together.
