Study of Lead Recycling by the Cupola Furnace and Rotary Furnace Using Different Refractory Materials.

Abstract

In this thesis we are discussing lead recycling by the cupola furnace and the rotary furnace. And the changes are replacing the raw materials with the refractory materials. First, useless batteries have been collected after they broke it and the lead containing materials has been separated. After separating material has been put in the cupola furnace mixing with the coal and then starts firing it and apply pressure by the blower. Which makes it start melting and lead has been exerted out and using moldings and casting making bars by which it can be transferred from one place to another place easily. And after that ace has been collect from bags in chimneys are known as fly ace and the scrape which are left in cupola furnace are containing lead are not separate by primary smelting process in cupola furnace that’s why rotary furnace has been used for secondary smelting process that fly ace and scrape (kita) are used for separating lead. And parts of cupola furnaces and the rotary furnaces parts are described and refractory materials which are used to construct and making some changes for increasing the production rate.
