摘要： Two rolls are supported laterally in bearings in two pairs of side-by-side members with the members being supported by a frame. Adjustment of synchronization and registration is accomplished by adjusting the relative positions of the side-by-side members in or against the rolling direction. The relative positions of the rolls can be adjusted by use of notches engraved in the ends of the rolls; and can be continuously monitored with the aid of a stroboscope light. Magnetic signal devices and other sensors are also suitable for monitoring. Continuous adjustment of roll position is accomplished through low-pitch screws or through hydraulic or electric positioning motors.

摘要： An apparatus and method is presented for emptying metallurgical vessels, and in particular steelmaking converters containing metal and slag, whereby the slag is effectively separated from the metal during pouring. The apparatus includes at least on permeable refractory element located near the flow hole. An agitating gas is fed through the refractory element thereby creating a bubbling froth which effectively obstructs most of the slag from being carried along by the vortex which forms above the vertical flow hole.

摘要： A process for monitoring continuous casting molds is presented. A primary coil coaxially surrounding the continuous casting mold is powered with currents whose Fourier analysis includes several frequencies. Several secondary coils are also arranged coaxially between the primary coil and the mold and surround the mold. The secondary coils are placed around the liquid metal pool level region, with the secondary coil in the lowest location being located beneath the pool surface at all times and serving as a reference coil. The differences between the Fourier components of the signals measured on the various secondary coils and the reference coil are taken, related to the intensities in the primary coil, and analyzed by magnitude or phase. By comparison of the various signals, the presence of liquid metal or slag, the temperature prevailing in the particular region of the mold wall, are determined.

摘要： In an eleven-step butterfly rolling process for producing inertial sheet piling, the upset grooving hitherto used in the fourth step is eliminated and replaced by one or more flat rolling steps intended to work the bulges at the edges of the flanges so as to impart a grain structure parallel to the flat rolled surfaces and thereby avoid cracking after the edge portion has been bent into hook configuration.

摘要： A melt is contained in a vessel having below the level of the melt an at least gas-pervious wall portion. First the slag is removed, normally by pouring it off, from the melt. Then a finely divided treatment solids suspended in a gas is introduced through the wall portion into the melt. The melt reacts thoroughly with these solids. Immediately deslagging the melt substantially reduces its ability to pick up nitrogen or hydrogen. This can be enhanced by the further step, prior to introduction of the suspension, of adding pure lime to the melt to form a protective layer thereon. The vehicle gas for the powder of course is inert, normally argon. The vessel can also be sealed up with a tight cover after addition of pure lime to it and before introduction of the suspension. Otherwise in the subsequent desulfurizing nitrogen and hydrogen will enter into the metal matrix, especially if there is an appropriate slag present.

摘要： A mixture of fine-particle mineral coal and a fine-particle solid carrier of carbon is stored in a bulk store from which the mixture is withdrawn and continuously blown into a shaft furnace, e.g. a blast furnace. Sufficient carbon carrier is used to loosen the mixture and to prevent it from caking and sticking. A suitable carbon carrier is particulate compost obtained by rotting household refuse or sewage sludge.

摘要： A process of producing a colloidal mortar suitable for use as a lining of steel conduit pipes, boilers or the like, includes filling a mixer with water while imparting to water a rotary motion by a rotary agitator at a speed of 1500 m/minutes, feeding the mixer with cement while maintaining the rotary motion whereby the mixture forms a funnel-like profile within the mixer and adding to the mixture wet sand of humidity of 5-15% and in proportion of 1 to 2 parts of the cement content to obtain the colloidal mortar. Fiber rovings may be added to the colloidal mortar.
