Rotary furnaces should be harnessed because they form bases for melting of scraps of iron or steel and aluminum Essar steels manufacturing facility comprises pellet making, iron making and steel making and downstream facilities spread across India. receptacle, the rotary tube furnace can also be used for processes under protective gas or vacuum. The metal enters the melting chamber through the input door that is provided on the top of the melting chamber. Rotary furnaces range in size fromtom³ and produce betweenandtonnes per charge based on the metal content. Rotary furnaces ensure continuous work flow compact design that uses a minimum of floor space. Inside the melting chamber there is a graphite furnace. The slag from a rotary furnace in general contains Rotary furnaces are good examples of fuel-fired furnace. ¾Spillage of melted Rotary furnaces are batch furnaces that generally utilize oxy-fuel burners and limit the volume of off-gases. Working temperature: up to °C High temperature uniformity Overpressure control Step-less control of the hearth rotation speed Flexible operation system, the high temperature rotary furnace or high temperature rotary kiln (HTRK) as it is sometimes called. ENERGY EFFICIENT ROTARY FURNACE Depending on process, charge and required yTilting system (for tilting rotary furnaces): ¾The whole complex is assembled on a special base in structural steel so as to ensure arationaland rigidstanding. ROTARY FURNACE DESIGN CONFIGURA nONS A rotary furnace consists of an open-ended cylinder, revolving about its axis while at least a portion of it is maintained at a tempera ture sufficient to bring about certain desired reactions The Tilting and Rotary Furnace consists of mainly melting chamber and the base. The metal is melted in the graphite crucible Maximum heat utilization in the rotary furnace is favoured through its shape orientation, rotatory speed, insulation, recuperation, flame length and flame stabilization, type of fuel used and non-pulsating flow of air from the centrifugal blower. The rotary furnace design gives high utilization of the input energy compared with the stationary furnace; they are very flexible and can accept a wide variety of feed materials Rotary hearth furnace construction combines advantages of both continuous and chamber furnaces. A rotary furnace is a rotated around its 5 liter charge material incl.
