The Aim, the
Signaficance, and the Expected Outcomes of the Project:
Refractory-clinker
interaction leads to significant losses in cement production plants both
in terms of money and in terms of product quality. MgO in the clinker
derived from the refractory corrosion may lead to excessive swelling of
the concrete in the long term. This project aims at investigating the
interaction of fired magnesite refractory brick with molten clinker during
cement manufacture. A set of experiments are planned to understand these
corrosive reations on a microscale. This will provide us with information
related to identifying the potentially hazardous low melting and fluid
phases that may occur in the system. These phases can be identified by the
use of SEM-EDS (scanning electron microscope coupled with energy
dispersive x-ray microanalysis system). A statistical experimental design
will be used to produce a polynomial model of the system (prediction
equation) that describes the effect of various parameters on the amount of
corrosion of the brick. |
