Abstract: Various systems and method for acoustic monitoring of smelting furnaces and similar devices are disclosed. Acoustic sensors (and optionally other sensors) are mounted to the furnace. Acoustic emission events generated in the furnace are analyzed to identify conditions that exceed one or more thresholds. The location of acoustic emissions may be identified and reported. Output signals may be generated in response to acoustic emissions. The location of acoustic emissions may be used to identify the location of potential failures in the furnace.

Abstract: A reactor comprises an outer sidewall and a bottom wall enclosing a hollow chamber comprising a lower fluidized bed zone and an upper freeboard zone. A plurality of inlets is provided for injecting at least one fluidizing medium into the fluidized bed zone and creating a swirling flow. At least one feed inlet communicates with the fluidized bed zone; and at least one product outlet is provided for removing a product from the chamber, the outlet(s) communicating with either the fluidized bed zone or the freeboard zone. The reactor has at least one internal barrier located inside the hollow chamber, and at least partly located in the fluidized bed zone. The internal barrier(s) have at least one opening within the fluidized bed zone, such as an underflow opening, to permit internal recirculation of material from the product zone to the feed zone, thereby simplifying reactor structure.

Abstract: A highly flexible sealing arrangement designed to seal high-temperature furnace ports, particularly the electrode port of an electric furnace. The seal comprises an annular support member fixed to a flexible sealing member and employs the use of a garter spring to uniformly apply the desired amount of seal compression. The arrangement and flexibility of the sealing member allows the seal to adapt itself to the wide range of operating and upset conditions that typically exist for a furnace electrode seal. Frictional wear on the seal may be greatly reduced as the design inherently allows for a much lower amount of seal compression to be applied, furthermore, the seal is able to move axially which can significantly reduce wear caused by electrode regulation.
Abstract translation: 一种高度灵活的密封装置，用于密封高温炉口，特别是电炉的电极端口。 密封件包括固定到柔性密封构件的环形支撑构件，并采用使用卡箍弹簧来均匀地施加所需量的密封压缩。 密封构件的布置和柔性允许密封件适应于通常存在于炉电极密封件的宽范围的操作和镦锻条件。 密封件上的摩擦磨损可以大大降低，因为设计固有地允许施加更低量的密封压缩，此外，密封件能够轴向移动，这可以显着减少由电极调节引起的磨损。

Abstract: A chill mold is used to cool molten material to form a casting. A support holds the chill mold so that a bottom of the chill mold is elevated. A baffle is arranged to divert a generally horizontal flow of cooling air upwardly to impinge the bottom of the chill mold. A plurality of chill molds may be aligned generally in a row, and at least one fan may be arranged at an end of the row to direct the flow of cooling air underneath the chill molds. The size and the vertical position of the baffles may be varied along the row, so as to generally equalize convective cooling rates among the chill molds in the row.

Abstract: A system measures parameters of the electricity drawn by an arc furnace and, based on an analysis of the parameters, provides indicators of whether arc coverage has been optimized. Factors related to optimization of arc coverage include electrode position, charge level, slag level and slag behaviour. More specifically, such indicators of whether arc coverage has been optimized may be used when determining a position for the electrode such that, to an extent possible, a stable arc cavity is maintained and an open arc condition is avoided. Conveniently, by avoiding open arc conditions, the internal linings of the furnace walls and roof may be protected from excessive wear and tear.

Abstract: A system and method for dry ablation beneficiation of ore. The system comprises a nozzle to emit an air stream, and a feeder to provide ore particles for entraining in the air stream and colliding. The ore comprises gangue grains bound together with a cementing material. The cementing material comprises a desired material. The collisions are controlled to help preferentially break the cementing material over breaking the bonds holding a gangue grain together. The system also comprises a classifier to separate broken cementing material from the remaining material (which includes gangue grains) based on size. The method comprises entraining the ore particles in an air stream and colliding to preferentially break the cementing material. The ore particles may be collided with each other or a surface. The broken cementing materials are then separated from the remaining materials (which includes gangue grains). The enriched ore is the separated cementing material.
