Technical details

Universal Tilting Rotary Furnace is a new generation of Rotatable and tiltable melting furnace for secondary non ferrous metal extraction. This furnace is latest of its kind in the world.

A significant advantage claimed for the UTRF is that it can be both rotated and tilted. First of all, the scrap is loaded in to the furnace with the smelting salt and the furnace is locked shut. By firing the burner that is mounted on door the material is heated with the help of air and oil/gas until it reaches melting point. Heating up is considerably faster resulting in saving of energy as well as melt loss. During the whole melting process, the UTRF rotates. This improves the heat transfer rate from the burner to the material, and additionally, the rotating movement promotes the separation of liquid metal from the oxide and other impurities. When all the scrap is melted, the burner can be switched off.

After opening the furnace door, the liquid metal can be poured in to the holding furnace or to the other station by tilting the furnace. Through tilting the furnace even further the salt cake can be taken out. Using the UTRF enables a very high yield of material to be delivered with very low energy consumption.

If compared with traditional reverbaratory furnace the yield is 2 to 5 % higher and the energy saving is to the tune of 25 to 40 %. Another significant advantage by this furnace is that metal can be recovered efficiently from the dross. This furnace is highly useful in making master alloy as during the whole melting process the furnace rotates resulting in homogenous mixing of other elements in metal.
