Viscosity of Copper slags
Viscosity-composition Relationship
For most typical slags the content of several minor components(Al2o3 , Mgo , Zno) Has been varied , and their influence on the slag viscosity has been investigated. Al2o3 markedly increases viscosity beyond 7% , Zno is the best basic reagent to lower viscosity and 5% Mgo gives the highest viscosity.
Viscosity-composition Relationship
Several authors have claimed that some indices of viscosity exist that lead to fairly simple relationships with chemical compositions at constant temperature. Winterhager and Kammel[1] proposed the equations
Viscosity = a/(Kz-b) (1)
a and b are constants; equation valid when Kz is of low value, and
Viscosity = c-d. Kz (2)
c and d are constants; equation valid when Kz is of high value . viscosity module' Kz is written:
Kz = [ %Feo+%Cao+%Mgo+%Zno+%Pbo]/ [%Sio2+%Al2o3] (3)
Higgins and jones[2] correlated viscosity with a "modified viscosity ratio" ,MVR , which we adapted as follows:
MVR ={ 056[Al+3]+1.40[Si+4]}/ {0.44[Fe+2] +0.36[Ca+2] +0.46[Mg+2] +0.44[Zn+2] +0.29[Pb+2]} (4)
In neither case was it possible to obtain a satisfactory correlation between the indices and viscosity of the slags. The trends of the plots were correct , but the dispersion of the values was very high , particularly at low temperatures.

[edit] Article creations
Hi. I note you've created a number of new articles, such as Calculations on Scrap addition during copper blowing. May I suggest reading some help files, such as Help:Contents/Editing_Wikipedia and Wikipedia:Your first article before creating articles, to learn the markup and presentation standards that Wikipedia has? If you have any questions, please feel free to ask at the help desk, or on my own talk page. Good luck, and happy editing! Lankiveil (speak to me) 11:49, 13 March 2008 (UTC).

[edit] DISCIPLINES IN TRIBOLOGY
A proposed deletion template has been added to the article DISCIPLINES IN TRIBOLOGY, suggesting that it be deleted according to the proposed deletion process. All contributions are appreciated, but this article may not satisfy Wikipedia's criteria for inclusion, and the deletion notice should explain why (see also "What Wikipedia is not" and Wikipedia's deletion policy). You may prevent the proposed deletion by removing the {{dated prod}} notice, but please explain why you disagree with the proposed deletion in your edit summary or on its talk page. Also, please consider improving the article to address the issues raised. Even though removing the deletion notice will prevent deletion through the proposed deletion process, the article may still be deleted if it matches any of the speedy deletion criteria or it can be sent to Articles for Deletion, where it may be deleted if consensus to delete is reached. If you agree with the deletion of the article, and you are the only person who has made substantial edits to the page, please add {{db-author}} to the top of DISCIPLINES IN TRIBOLOGY. —BradV 05:17, 11 April 2008 (UTC)
[edit] April 2008
Hi, the recent edit you made to DISCIPLINES IN TRIBOLOGY has been reverted, as it appears to be unconstructive. Use the sandbox for testing; if you believe the edit was constructive, ensure that you provide an informative edit summary. You may also wish to read the introduction to editing. Thanks.

- I assume that by blanking the article that you created you wanted the page deleted. I have tagged the page as such. LittleOldMe (talk) 10:38, 11 April 2008 (UTC)
