Conclusions
A composition was developed based on magnesite-chromite guncrete body with low shrinkage for guncreting the walls and roof of open-hearth furnaces when they have been stopped for cold repairs. The low shrinkage of the body is due to the process of spinel formation taking place in the coating during its firing.
