Holding furnaces receive molten metal from either the primary reduction potlines or from the melting furnaces.

Geosciences

Awu is a remote and little known active volcano of Indonesia located in the northern part of Molucca Sea. It is the northernmost active volcano of the Sangihe arc with 18 eruptions in less than 4 centuries, causing a cumulative death toll of 11,048. Two of these eruptions were classified with a Volcanic Explosivity Index (VEI) of 4. Since 2004, a lava dome has occupied the centre of Awu crater

Optimizing machining parameters to combine high

2016/4/1A detailed case study has been presented to illustrate the actual working of our approach. In one case a productivity improvement of 173% was observed over 40 optimization cycles. And in another case (presented in a summarized form) an improvement of 540% in the parts variable cost over 42 optimization cycles was realized.

2014/9/1In this case, another 3-min degassing was necessary to eliminate the residual pores entrapped during the casting process. Then the suspension was kept in the vacuum oven at 60 C for a complete gelation reaction by avoiding the possible polymerization inhibition caused by

Current Technology and Trends in Aluminium Processing

Morgan's new degassing rotors are made using silicon carbide, a high-performance and cost-effective substitute to conventionally used graphite material. Previously graphite was the most widely used material to degas rotors, but frequent changeovers and high replacement costs have reduced their demand.

Deep mantle melting, global water circulation and its

2020/12/10In the first study of the ocean mass history, McGovern and Schubert focused on the influence of water content sensitive rheology on the history of degassing. Similar studies were made by Crowley et al. 2011 and Franck and Bounama ( 2001 ) (we note that Rpke et al. 2006 and van Keken et al. 2011 did not consider the feedback between water-dependent rheology and global water cycling).

Geologically Meaningful 40Ar/39Ar Ages of Altered Biotite

Discordant biotite 40Ar/39Ar age spectra are commonly reported in the literature. These can be caused by a number of processes related to in vacuo heating, homogenization of the argon distribution, and production of misleadingly flat age spectra. Problematic samples are typically derived from metamorphic belts; thermal overprinting and chloritization are two of the main known causes of

Silicon Carbide Degassing Rotors Offer Long Life and

Graphite has traditionally been the most widely used material for degassing rotors around the world. However, to address the high replacement costs and frequent changeovers associated with this material, Morgan has leveraged its advanced silicon carbide crucible technology and materials expertise to develop a range of rotors which last up to five times as long before requiring replacement.
