4.Technical Information of Perlite Usage in Foundry Industry
Perlite Ore is used in many Ferrous and Non-ferrous foundries as a “slag coagulant”. It is used in ladle topping where granulated perlite ore is added to molten metal pouring ladles. The ore reacts with the slag in the ladle to allow easy removal of the slag layer. Expanded perlite forms an efficient insulating blanket in cases where it is desirable to maintain a metal temperature in the ladle. When it is introduced during ladle filling, a gentle rolling motion is produced which cleanses the metal by coagulating impurities. In addition, ladle- lining life is increased by virtue of a vitreous residual coating left on the refractory by the perlite
Perlite in the ore form is used in high temperature applications in the steel, ferrous and non-ferrous industries, as a slag coagulation agent, in ladle topping compounds, as an ingredient in exothermic and insulating sleeves and as a cushioning
