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.
