Comparing the commercial production process of iron and aluminium in relation to their properties

Extracts from this document...

Introduction

´╗┐Comparing the commercial production process of iron and aluminium in relation to their properties The molten iron is usually used in moulded into cast or pig iron and transformed into many kind of steel, some of which includes stainless steel, high speed steel or chromium steel. During the transformation of iron and aluminium into these products, these elements go through two production processes, the batch process and the continuous process. The cost of extracting these metals can be extremely high because of the high amount of electricity that it requires. The continuous process is used to manufacture iron because of its high demand in the industry and this demand is due to its good quality and ability around other substances, heat and electricity. ...read more.

An advantage of the continuous process is that it requires less work compared to the batch process. http://www.conmark.com/images/Duralyzer/KamyrProfiles.jpg Batch process The batch process is done by producing one lot at a time. Because the batch process is about producing a lot at a time, it requires more workers to make sure that the amount of product required is produced obtained at the end of the production. Since the batch process is about making one lot at a time, it is mostly used to manufacture small amount or quantity of chemical on request. The rate of production in the continuous process is much more higher compared to the rate of production in the batch process because this process is shut down often after production whereas production in continuous process hardly stops. ...read more.

https://answers.yahoo.com/question/index?qid=20100616195013AAo9hQb Because of its high melting point(over 2,000°C), Aluminum oxide would cost too much to melt so that is why it is dissolved Instead using molten cryolite which is an aluminum compound that has a lower melting point than aluminum oxide. By using cryolite, we help reduces some of the energy costs involved in extracting aluminum. In an aluminum oxide electrolysis tank, both the negative electrode and positive electrode are made out of graphite, a form of carbon. Aluminum metal forms at the negative electrode and sinks to the bottom of the tank, where it is often tapped off. Oxygen forms at the positive electrodes. This oxygen reacts with the carbon of the positive electrodes which forms carbon dioxide and they gradually burn. http://www.docbrown.info/page04/Mextracta.htm ...read more.
