| 20120037831 | DRIVE DEVICE OF A REGULATION VALVE FOR CASTING LIQUID METAL - A device for driving a regulation valve for casting liquid metal contains a main rod controlling the opening and closing of the valve, and a coupler linking the main rod and the valve. The device also contains a coupler controller able to activate and deactivate the coupler, enabling linkage and detachment of the main rod and the valve. | 02-16-2012 |
| 20110293365 | CEMENT PLANT REFRACTORY ANCHOR - A cement plant refractory anchor ( | 12-01-2011 |
| 20110278331 | CASTING SHROUD, MANIPULATION DEVICE FOR THIS SHROUD, AND DEVICE FOR DRIVING A VALVE - A manipulation device for a shroud for casting liquid metal comprises holding means for the shroud, downstream of a metal flow control valve, this valve being able to assume an open configuration and a closed configuration under the action of drive means. The manipulation device comprises fixing means affixed to the drive means for the valve. A ladle shroud for the flow of liquid metal from a casting ladle to a metal tundish has a longitudinal axis and comprises a shroud gripping head at one end. The gripping head is fusiform. | 11-17-2011 |

| 20100222201 | Cast Bodies, Castable Compositions, And Methods For Their Production - A low-water-content castable composition produces cast products with an increased modulus of rupture, an increased cold crushing strength, and decreased porosity. The composition employs closed fractions of constituent particles with specified populations and specified gaps in the particle size distribution to produce these properties. The composition is suitable for refractory applications. | 09-02-2010 |
| 20100218559 | HIGH TEMPERATURE ROLL - The present invention describes a roll for use in glass manufacture, especially non-dusting TFT glass. The roll may include a hollow fused silica cylinder. End caps are mechanically fixed to the roll. Pulling flats are fixed in place by inner and outer end plates. A compression fitting secures at least the outer end plate to the roll. The roll may be reinforced with an internal metal rod that is secured to the shaft by a plurality of supports. The supports accommodate differences in thermal expansion. | 09-02-2010 |
| 20090168831 | ELECTRIC ARC FURNACE ROOF TOP AND CENTRAL PORTION FOR THIS ROOF TOP - An electric arc roof furnace top contains a central portion and a peripheral portion surrounding the central portion. Each of these portions has an inner surface suitable for facing the furnace inner space. The inner surfaces of the peripheral and central portions form together a step so as to raise the inner surface of the central portion in relation to the inner surface of the peripheral portion with respect to the furnace inner space. | 07-02-2009 |
| 20090160108 | Refractory Article and Production Process Thereof - The present invention relates to refractory articles in general having improved surface properties. The objective of the invention is to propose an improvement of the refractory articles comprised of a fused silica matrix which will overcome the some of the defects while keeping the excellent known properties of the fused silica matrix. This objective is reached when a sintered ceramic phase is present in the porosity of at least a portion of at least a surface of the matrix. The present invention also relates to a process for producing such an article. | 06-25-2009 |
| 20080292524 | Crucible for the Treatment of Molten Silicon - A crucible for the treatment of molten silicon includes a basic body with a bottom surface and lateral walls defining an inner volume. The basic body comprises at least 65% by weight of silicon carbide, and from 12 to 30% by weight of a constituent selected from silicon oxide or nitride. Moreover, the basic body comprises at least one silicon oxide and/or nitride coating, at least on the surfaces defining the inner volume of the crucible. | 11-27-2008 |
| 20080260608 | Crucible for the Crystallization of Silicon and Process for Making the Same - A protective coating is prepared for, and applied to, crucibles used in the handling of molten materials that are solidified in the crucible and then removed as ingots. Crucibles containing this protective coating may be used for the solidification of silicon. The coating has a specified oxygen content and contains a mineral binder and silicon nitride or silicon oxynitride. | 10-23-2008 |
