Metal instabilities and its effect on cell performance during aluminium smelting A Agnihotri1,a, S U Pathak2,b and J Mukhopadhyay3,c 1Scientist-V, Jawaharlal Nehru Aluminium Research Development and Design Centre, Wadi, Nagpur – 440023, Maharashtra, INDIA 2Professor, Department of Metallurgical & Materials Engineering, Visvesvaraya National Institute of Technology, Nagpur 440010, Maharashtra, INDIA 3Visiting Professor, Department of Material Science and Engineering, Indian Institute of Technology, Gandhinagar 382424, Gujarat, INDIA aaaagnihotri@yahoo.com, bsupathak@mme.vnit.ac.in, cjm@iitgn.ac.in Key words: Aluminium, magnetic field, cell voltage, instability, noise, voltage Abstract The Hall-Heroult process for the production of aluminium is based on the electrochemical reduction of alumina (Al2O3) dissolved in a cryolite (Na3AlF6) based electrolyte.
It is true that back reaction is one of the important factors for lowering of current efficiency but there are many other factors as listed below which play important role in lowering of current efficiency: · Other material being co-deposited · Some of the products reduced at the cathode may remain in electrolyte phase and subsequently be re-oxidised (current stealing) · Electronic conductivity of electrolyte and physical short circuiting · Other heterogeneously formed compounds Unstable cell operation can be judged by abnormal value of counter electromotive force.

Comprehensive Evaluation on Sensitivity of Ecological Environment in Chengde Chun Li1,a, Jinping Qian2, b College of Resource and Environment Sciences, Hebei Key Laboratory of Environmental Change and Ecological Construction, Hebei Normal University, Shijiazhuang 050024, China chunlizhpdp@126.com Keywords: ecological environment, sensitivity comprehensive evaluation, Chengde Abstract.
According to the materials of soil types in Chengde, the classification result of soil texture factor’s influence on soil erosion sensitivity has been worked out with the use of ArcGIS.
Vegetation coverage The ground vegetation influence on the land desertification is the important factors,The higher the vegetation coverage are not easy to prosperous soil desertification.According to the present situation of the ecological environment in the investigation of remote sensing image material in Chengde,We divided Chengde city into non-sensitive area , slightly sensitive area, medium sensitive area, highly sensitive area and extremely sensitive area.Non-sensitive area includes most parts of Chengde City,which the vegetation coverage is high, not easy to cause land desertification;slightly sensitive area includes Fengning County, plateaux in dam of Weichang County, the east of Luanping County and the south of Xinglong,which the vegetation coverage is moderate area;medium sensitive area includes Fengning County Yuer Mountain, Sichakou, Grassland, Weichang County YudaoMouth, Xilongtou and Nanshanju and so on, which areas vegetation coverage is less ;highly sensitive area includes
The number of the days winter monsoon wind speed is greater than the sand wind speed Wind speed only in more than a critical value until circumstances may blow and handling of soil particle material to the air,Therefore,Wind speed is the effect of soil particles of handling important factors.According to the research,sand wind speed wind of soil mass is 6 m/s, So choose the data of the number of days spring wind speed more than 6m/s in Chengde,and the standards in 《Ecological function division interim rules》,Chengde city will be divided into general area, slightly sensitive, medium sensitive area, highly sensitive area and extremely sensitive area.General area includes Yuerya Town , Nianzi Town, Dongdadi, Huanjian, Mubeiloutai, Mengziling, Dushigouzi, Tashan, Huapiliuzi and Kuancheng Country of Kuancheng Country ;Xiabancheng south and Bajia of Chengde Country;Bgualing Town, Gushanzi Town, Gualanyu Town, Banbishan Town, Lanqiying Town, Moguyu Town, Dazhangzi Town and Anziling Town of
