| 84 | Ceramic porous bodies suitable for use with superalloys | US387708 | 1982-06-11 | US4697632A | 1987-10-06 | Nick G. Lirones |
| Ceramic porous bodies, including ceramic foam filters and smooth-faced ceramic objects, e.g., ceramic foam bricks, ceramic foam melting crucibles, and ceramic foam cores, made in accordance with the present invention are suitable for use with molten metal in general and molten superalloys in particular. The invention also provides a tundish for use with ceramic foam filters to filter metal en route from a metal furnace to a casting mold, and a melting device for use in casting metal which employs a ceramic foam filter as a bottom pour valve for a melting crucible such that the ceramic foam filter valve regulates the flow of molten metal therethrough in order to permit an entire ingot of metal to melt in the melting crucible before any metal begins to pour from the melting device into a casting mold. | ||||||

| The present invention provides an improved lining structure composition on the inner surface of a tundish by forming an alumina-silica-base intermediate lining layer over which a magnesian surface coating layer is formed by gunning. It solves the adhesion defect on a refractory lining of the tundish and enables longer operation of the tundish. | ||||||

| 91 | Low density sleeve | US537063 | 1974-12-30 | US3966480A | 1976-06-29 | James D. Evans |
| A low density, refractory stopper rod sleeve has a substantially imperforate surface and a core containing a plurality of randomly spaced, internal and discontinuous small voids. The density of the sleeve is less than 2.0 gr./cc and the preferred density range is 1.60 to 1.85 gr./cc. The sleeve is made up of six parts by volume refractory clay mix to four parts of a combustible waste material such as wet sawdust which does not exceed a screen size of 10 mesh. The sleeves are made by the stiff mud process which includes extruding the mix into solid, cylindrical blanks and forming the blanks in a die in which the final sleeve is slidably disengaged from the die. After drying the sleeve is processed through a normal firing cycle until it reaches approximately 1500.degree.F at which time it is held for a prolonged period of time to drive off the carbonaceous material associated with the waste combustible in the mix. | ||||||
