Roller kiln for the thermal treatment of a material to be fired, the use of the roll type furnace and method for the economical treatment of a material to be fired with heat

摘要

It is a roll type furnace for the thermal treatment of a material to be fired is provided, which is characterized by the fact that it at least one roller, the at least one of the heating space middle segment which is arranged in the center of the roller and two at least partially outside of the heating chamber end segments which are arranged in each case at one end of the roller, the first and second end segment in each case a frictional and / or positive connection with the center segment and the first and second end segment a lower specific thermal conductivity than the center segment. In this way, it is achieved that the heat losses of the roll type furnace are minimized and the roller hearth furnace can be operated very economically. It is the use of the roll type furnace for thermal treatment of a material to be fired have been proposed and a method for the economical treatment of a material to be fired is presented with heat.n="24"
