Dynamic Modelling of an Operating Aluminium Reduction Cell
The operating conditions in the Hall-Héroult process used for aluminium production have become more critical in recent years due to need to optimise current efficiency and minimise the energy consumption per kilogram of aluminium produced. The tightening of operating parameters makes it more difficult for existing control systems employing global control practices to prevent the increase in the...
متن کاملAluminium-containing antiperspirants contribute to aluminium intake
Antiperspirants denote cosmetic products with an anti-perspiration effect which are available as roll-ons, sticks, creams or aerosols (sprays). The anti-perspiration effect is achieved by means of aluminium salts which block the ends of the sweat ducts for a certain amount of time. The safety of aluminium and antiperspirants continues to be critically examined. This is notably true with regard ...
متن کاملCreep of Aluminium and Aluminium Alloys
This chapter constitutes an introduction to creep and to the creep response of Aluminium and its alloys. Its major goals are: to provide basic information on creep and its mechanisms to give a description of the more extensively used mathematical relations among creep variables (time, stress and temperature) to illustrate the creep response of pure Aluminium and of Al-Mg alloys to provide a syn...
متن کاملEvidence of aluminium accumulation in aluminium welders.
Using atomic absorption spectrometry the aluminium concentrations in blood and urine and in two iliac bone biopsies obtained from welders with long term exposure to fumes containing aluminium were measured. The urinary excretion of two workers who had welded for 20 and 21 years varied between 107 and 351 micrograms Al/l, more than 10 times the concentration found in persons without occupational...
