摘要： During the tapping of molten steel from the converter prior to continuous casting, the onset of slag from the taphole is difficult to detect. Excessive slag carryover from the converter results in a rich slag cover for the steel, favouring reversion of phosphorus, manganese (and other constituents if present) in the quiescent state. The onset of slag is detected remotely, based on the fact that the spectral emission lines of sodium and potassium may be resolved in the light emission from the steel, which characteristic is absent in the slag. The optical emissions (1) from the furnace taphole are accessed by an optical head (200) about 20 metres distant, focussed by a lens (2) and divided by a beamsplitter (3). Each path after the beamsplitter (3) has an optical interference filter (4, 6) placed before a photodetector (5, 7). Optical interference filter (6) passes wavelengths centred on the emission line (589.3 nm for Na or 768.2 nm for K) and optical interference filter (4) passes wavelengths centred adjacent to the emission line, so that the output of photodetector (5) is proportional to background radiation only. Light not passed by the filters (4, 6) is reflected back towards the furnace. Some light (11) is incident upon a translucent screen (8) and this is used to align the instrument during installation. The outputs of the photodiodes are fed into an automatic control and output system with fibre optics, alarm indicators and computer control.

摘要： Apparatus for cladding and thus reclaiming a worn rolling mill roll by fusing a surface layer thereon, comprises an electro-slag mould (7); a slewable derrick structure (Fig. 2) able to feed a split tubular, consumable electrode (51) into the mould; a turn-table (8) supporting the mould; a tiltable induction furnace (55) to charge the mould with molten flux; product transport means (Fig. 1) to lift a worn mill roll through the mould and withdraw it downwardly from the mould as cladding proceeds and comprising rigid hangers (12) extending downwardly from the turn-table, an elevator carriage (14) with a product holder and adapter including a mould plug (29), and power driven jack screws (19) to raise and lower the carriage (14); and drive means (9, 11) to cause rotary oscillation of the turn-table and the components carried by it, including the roll, relative to the electrode. A method of cladding a worn roll by the electro-slag process is also disclosed wherein the mould and roll are rotationally oscillated about the axis of the roll relative to the electrode, as cladding proceeds.

摘要： In an internal combustion engine (1) a system for improving fuel combustion comprising an air inlet leading to a turbocharger (3) having a compressor (4), oxygen producing means (6) connected to said compressor (4) and preferably to the inlet thereof and to the air/fuel inlet (7) of said engine (1) such that the combustion air supply is enriched to between about 24 % and 28 % of oxygen by volume. The introduction of additional oxygen to the combustion air supply allows the use of fuels, such as residual or heavy fuel oils, which are otherwise not suited for combustion in high speed diesel engines. The oxygen enrichment of the combustion air supply reduces or removes the need for an intercooler and provides better transient response to demand for increased power.

摘要： A method of locating an object in an optically dense atmosphere (15) includes transmitting a pulsed wave optical signal (16) towards the object through the atmosphere adjacent the object. A particular application is the location of the surface (14) of the contents of furnace (10), for example the burden (12) in a blast furnace. A received signal including at least a portion of the signal reflected by the object is monitored and analyzed in relation to the transmitted signal to determine the location of the object. This analysis comprises identifying the trailing edge of the received pulse signal to ascertain the time elapsed between the detection of the transmitted and received signals.
