Permeability optimization based on integrated model and traversing search algorithm for lead zinc sintering process

To deal with the problem of the permeability control for the lead zinc sintering process,a permeability optimization control method for the sintering process based on integrated predictive model and traversing search algorithm is presented in this paper.Firstly, a neural network predictive model and a gray forecast model are established.By using optimal combination algorithm,a synthetic per- meability integrated predictive model of the lead zinc sintering process is designed through combining two models.Then,Permeability of comprehensive evaluation model is established by combining with the temperature of 14~* bellows and burning through point.Finally, the permeability optimization control for the sintering process is realized by controlling values of the second proportion and the water content of mixture,which is gained through traversing search algorithm.The result of simulation shows that optimization control method can improve the permeability of the sintering process and stabilize sintering process.
