Function analysis and amelioration of removing silicon sludge technology in silicon steel pickling system

For the silicon steel pickling system, the condition of bad dependability and easy destabilization was systematically analyzed. The formation process and mechanics of the silicon scale in pickling system was described. And a systematic statement was made on the effect of the silicon sludge and scale on the reduction of turbulence pickling efficiency. The processing principle and function structure of the online sedimentation, and the principle and the different model of the caustic washing were expounded. Based on the further analysis of the pickling system, the online sedimentation and the caustic washing system, the processing logistic relation of the three systems was clear firstly, combined with the inactivation mechanics of the pickling system caused by the silicon scale. The useful betterment had been done contraposing the imperfect points in the system, which improved the dependability and stabilization of all system, and decreased the unit operation cost.
