The invention discloses a method for adjusting 
calcination temperature of 
rutile type 
titanium dioxide, which can be used for adjusting the 
calcination temperature of the 
rutile type 
titanium dioxide in real time according to specific productivity of a 
rotary kiln. The method comprises the following steps: determining the corresponding 
calcination temperature when the 
rotary kiln is used for performing production according to different productivities; selecting the calcination temperature of a corresponding 
crystal form transformed band; and performing real-time detection on the calcination temperature of the 
rotary kiln in the production process, and then adjusting the calcination temperature of the rotary 
kiln. The invention also discloses an 
automatic control method for the method for adjusting the calcination temperature of 
rutile type 
titanium dioxide. By adopting the 
automatic control method, a detection device is used for transmitting productivity conditions of the rotary 
kiln to a PLC (
programmable logic controller), and then the PLC controls the corresponding temperature adjusting equipment to adjust the calcination temperature of the 
crystal form transformed band, so that 
automatic control is realized. By virtue of the calcination temperature adjusting method, the production 
energy consumption can be reduced, and the finished product quality of 
titanium dioxide can be ensured; and meanwhile, by virtue of the automatic control method, automatic control can be realized, the working efficiency can be improved, and the production cost can be reduced.
