In respect that various requirements of load and temperature on different parts of the baker, firebrick lining was chose reasonably, and the dosage of light heat preservation brick is in enlargement. As a result of that, the weight of the furnace was decreased, and increased its performance of heat preservation and cumulation was increased consumedly. With the use of ""W"" type fire tunnel and straight-through dilatation joint, and two enlargement of the perpends on the wall appropriately, all the problems of heat preservation in the anode baker, uniform temperature in the tunnel, and its life span were solved effectively. In the research of anode blocks in and out of the furnace, and of tidying it up, the multi-function crane clamps was alented and the assembling unit was reconstructed, which made it easy to automatic ally assemble the carbon blocks of various specifications with only one set of assembling unit.In the aspects of automation, a new type pulse combustor and solid thermocouple, as a result of that, not only the control accuracy of the fire tunnel's temperature was increased, but also the system function was improned to be more dependable, safe and practicable.
