Metal matrix composite and method of forming

Use of Ca in metal matrix composites (MMC) allows for incorporation of small and large amounts of ceramic (e.g. rutile Ti0 2 ) into the metal (Al, or its alloys). Calcium remains principally out of the matrix and is part of a boundary layer system that has advantages for integrity of the MMC. Between 0.005 and 10 wt. % calcium (Ca) may be included, and more than 50 wt. % of rutile has been shown to be integrated. Rutile may therefore be used to reduce melt loss due to calcium from an aluminum or aluminum alloy melt.

Process for melting aluminum

Zum Einschmelzen von Aluminium in einem Ofen ist ein Verfahren bekannt, bei welchem ein aluminiumhaltiges Einsatzmaterial einem Ofen zugeführt, darin in einem oberen Bereich des Ofens durch Ofenabgas vorgewärmt und mittels mindestens eines Brenners unter Bildung einer Aluminiumschmelze in einem unteren Bereich des Ofens erhitzt wird, wobei dem Brenner ein sauerstoffreiches Gas und Brennstoff zugeführt und damit eine auf das Einsatzmaterial im Schmelzbereich einwirkende und zum Ofenabgas beitragende Brennerflamme erzeugt wird. Um hiervon ausgehend ein Verfahren unter Einsatz eines Sauerstoffbrenners oder eines Mischbrenners anzugeben, bei dem Nachteile hinsichtlich der Vorwärmung des Aluminiumeinsatzes vermieden werden, wird erfindungsgemäß vorgeschlagen, dass das Ofenabgas im oberen Bereich des Ofens abgezogen und im unteren Bereich mindestens teilweise als rezirkuliertes, erwärmtes Gas wieder eingeleitet wird.

一种多熔区区域熔炼生产高纯铝的方法，其工艺流程为：首先将原料精铝熔化铸成待提纯精铝锭；将待提纯精铝锭放入石墨舟中并推入多熔区区域熔炼炉中，通入惰性气体，然后接通电源，在多个冷却水管及多个感应加热线圈的作用下进行多熔区区域熔炼，制取≥5N高纯铝；化验检测确定前述≥5N高纯铝的质量等级和需要锯切的位置；根据化验检测确定锯切位置，将≥5N高纯铝与高杂质铝锯切分离；将≥5N高纯铝加入高纯石墨坩埚中进行熔化后铸锭；将≥5N高纯铝锭封装后销售。借由上述技术方案，本发明多熔区区域熔炼法采用多熔区，循环二～四遍就可实现成倍次数的区域熔炼提纯，从而极大提高生产效率，降低生产成本，促使高纯铝实现规模化生产。

Method for the treatment of aluminum in a furnace

The invention relates to a method for the treatment of aluminum in a furnace, wherein a material containing aluminum and optionally one or several salts is introduced into the furnace, the material is melted by adding heat with the aid of at least one burner supplied with a combustive agent and combustible in order to obtain melted aluminum which is optionally covered with a slag comprising alumina and at least one salt, and the concentration of carbon monoxide COm and/or hydrogen H2m in the furnace or in the vapors exiting from the furnace is measured. The combustive agent supplied to the at least one burner comprises more than 10 % oxygen by volume, preferably more than 21 % oxygen by volume and the method comprises a final reduction phase for the oxidation of the melted aluminum during which the combustive agent flow is substantially constant while the flow of combustible injected into at least one burner is selected according to the concentration of metal oxide carbon monoxide COc and/or metal oxide hydrogen H2c in the atmosphere or vapors or vice versa. The concentration metal oxide carbon monoxide COmo and/or metal oxide hydrogen H2mo is calculated as the difference in the measured species concentration and the intrinsic CO or H2 species concentration caused by combustion of the combustible and combustive agent in the furnace with the at least one burner with the absence of a charge in the furnace.

Aluminum holding furnace

An aluminum holding furnace comprises an asbestos lining on the inside of a steel housing. Heat insulating bricks line the asbestos in the housing. A burner device heats the furnace.

Integrated quiescent processing of melts

A quiescent melt handling system includes a melting furnace and a holding furnace communicating with the melting furnace for holding a molten metal melt. The holding furnace has a relatively large surface area and a relatively shallow depth, having a width to depth ratio in the range of 4-100 to 1. Also provided is structure in the holding furnace for separating inclusions from the melt in the holding furnace. A mold communicates with the holding furnace. A counter gravity casting system, which might comprise a vacuum assisted casting system, draws the melt into the mold.

Conductive metal melting furnace, conductive metal melting furnace system equipped with same, and conductive metal melting method

To provide a technique that reliably and quickly melts conductive metal, there is provided a conductive metal melting method including: rotating a magnetic field device formed of a permanent magnet, which includes a permanent magnet, about a vertical axis near a driving flow channel of a flow channel that includes an inlet through which conductive molten metal flows into the flow channel from the outside and an outlet through which the molten metal is discharged to the outside and includes a vortex chamber provided between the driving flow channel provided on an upstream side and an outflow channel provided on a downstream side, and moving lines of magnetic force of the permanent magnet while the lines of magnetic force of the permanent magnet pass through the molten metal present in the driving flow channel; allowing the molten metal to flow into the vortex chamber by an electromagnetic force generated with the movement to generate the vortex of the molten metal in the vortex chamber into which the raw material is to be put; and discharging the molten metal to the outside from the outlet. The conductive metal melting method further includes driving the molten metal present in the outflow channel toward the outlet by an electromagnetic force generated with the movement of the lines of magnetic force as necessary.

Apparatus for holding and refining of molten aluminum

The incorporation of a small amount of metal fluoride or fluosilicate into the refractory fibrous insulating board lining of an aluminum refining vessel prevents the infiltration of the internal voids of said lining by molten aluminum.
