摘要： A load indication system monitors not only the total frictional load on the mold oscillator in a continuous casting apparatus, but also monitors the difference in the oscillator load at various locations around the mold to detect mold wobble and load imbalance. In addition, both the total frictional load and the mold wobble are monitored by detecting their peak-to-peak values. To this end a continuous casting apparatus comprises a mold (5), oscillating means for imparting an oscillating motion to said mold at a plurality of locations including at least a first and second locations, and monitoring means for providing an indication of differences in the oscillating motion at the first and second locations.

摘要： A composition for marking or for use as an anti-scaling coating on metal products includes solids of 30 to 50 parts by weight pigment, 43 to 58 parts by weight water soluble alkali metal silicate binder, at least 50 percent of which is sodium silicate and in which the ratio of silica to alkali metal oxide is 2.60 to 3.25, and sufficient cross-linking binder to provide 1.5 to 5.0 parts B 2 0 3 , the weight ratio of total pigment to total binder being 0.50 to 1.0. The composition adheres when applied to metal products which are at temperatures of at least 250°F (121°C) or which are subsequently heated to such temperatures. A preferred method of making the composition includes mixing first and second soluble alkali metal silicate solutions. The cross-linking binder is added to one of the solutions prior to addition of the other solid materials. Utilizing the two starting solutions provides a final mixture having a lower viscosity than when a single soluble silicate starting solution of equivalent Si0 2 ratio is used.

摘要： A process is described for treating wastewater, such as blast furnace blowdown wastewater, containing 100 to 600 ppm ammonia and having a chemical oxygen demand of 50 to 500 ppm and possible further contaminants, including cyanide, cyanate, thiocyanate, sulfide and/or organic materials. Substantially complete nitrification of the ammonia into nitrite or nitrate, is achieved by microbially treating the wastewater in a fixed film biological treatment system, such as a rotating biological contactor, which includes microorganisms capable of converting ammonia to nitrite and microorganisms capable of converting nitrite to nitrate. The system preferably aiso contains microorganisms for removing cyanide and many be periodically acclimatized to expected peaks in free cyanide concentration.

摘要： he method relates to minimizing slag carryover when draining molten metal from a furnace. A polyhedral-shaped body (22) having density intermediate that of the slag (20) and metal (18) is thrown onto the surface of the slag within a restricted area over the furnace taphole (14). The body will float at the slag-metal interface, and tend to lodge with one of its corners projecting into the taphole as the final portion of remaining metal drains out of the furnace. The shape of the body and its dimensions are selected so as to only partially block the taphole opening, causing flaring of the stream so as to signal a furnace operator of the impending flow of slag from the furnace. The operator then shuts off flow to prevent carryover of slag onto the molten metal already tapped. Since only the edges of the body contact the taphole, of the body does not become welded to the wall of the taphole and therefore is easily dislodged without loss of time between heats.

摘要： Valve plates for sliding gate valves have constructions exemplified by Figure 1 in which the refractory components are mounted in metal trays. The valve plate (18) has two refractory plate members (20, 21) bedded on cement (19) in the bottom of the tray (17); plate member (20) is orificed (at 14) to convey molten metal to an undermounted nozzle (16), which is joined to the plate member (2) by a male and female structure (28) such that the male part (29) of the plate member (20) protects the vulnerable inlet end of the nozzle (16). The plate member (20) - but not plate member (21) - is designed to be contacted in service by molten metal and is replaceably secured in the tray (17) which has apertures (32) for access of tooling used to displace the plate member (20) out of the tray when replacement of the palte member (20) is necessary.

摘要： A conductor roll used for masking one face of a metal strip while the other face is being electro-treating comprises an elastomeric-covered cylinder having a metallic contact ring (3) in the center thereof for electrical contact with the strip being treated. To minimize high transfer current densities, each edge of the contact ring has a cantilevered flange (4) overlying a portion of the elastomer (5). It has been found, due to differential thermal expansion at operating temperature of both the elastomer and the metal contact ring; that the cantilevered flange section of the contact ring is forced up to an excessive extent, resulting in high bending stresses generated in the strip at the region of the contact ring-elastomer interface. By providing a taper on the cantilever flange section to compensate for the difference in thermal expansion, bending stresses in the strip are reduced to insignificant values, thereby eliminating creases and scratches in the strip.

摘要： An improved insulation is provided for furnace members, particularly verticals, cross supports and skid pipes in slab reheating furnaces. The insulation includes a metal spring-clip (10) having outward projections (12, 12') on which refractory tiles (14,16) are formed in situ. A coating of organic lubricant is applied to the outer surface of the clip prior to the refractory being formed. This prevents adhesion of the tiles to the clip surface. Thus, when the clip is spread for installation on the pipes, the tiles will not break.

摘要： In the bottom blown process for the refining of molten steel, additional heat is generated for melting greater amounts of scrap, by injecting at least one secondary stream of an oxygen-containing gas to the space above the molten metal bath so as to combust the CO and H 2 evolving therefrom. The excess heat so generated is absorbed both by the bath and the furnace lining, causing overheating and rapid deterioration of the lining. For a given quantum of heat so generated the ability of the molten metal to absorb a greater portion of that heat and thereby maintain the temperature of the furnace lining within the practical limits has been found to depend to a significant extent on the design of the furnace itself. The invention is directed to conducting the refining process in vessels which provide, for a given bath capacity, greater top surface areas than has heretofore been employed.
