FAILURE MECHANISMS OF REFRACTORY LININGS FOR NONFERROUS FLASH SMELTING FURNACES
Although the flash smelting technologies use different furnace designs, the refractory linings are exposed to very similar aggressive environments and, as a result, the corrosion analysis results on one type of furnace could be generally applied to other furnaces of similar high temperature processes. Particularities regarding the different chemistries of the pyrometallurgical process and opera...
متن کاملModeling of Three Phase Electric Arc Furnaces
Abstract. In this paper are study the modeling of a three phase electric arc furnace installation. It is well know that the electric arc is a nonlinear element. Thus, for modeling his behavior, the authors are using a model which parameters like of a real electric arc. For simulation it was use the PSCAD EMTDC program. The simulations results are comparing with the measurements made of a 100t e...
متن کاملControl of Non - Ferrous Electric Arc Furnaces
An important aspect of non-ferrous metal production is the separation process known as smelting, in which the concentrated ore is melted and separated into two components of different densities: the slag and the matte. The smelting process is carried out through high-power heating in electric arc furnaces. In order to maintain a constant desired matte production rate and constant matte and slag...
متن کاملHarmonic distortion in a steel plant with induction furnaces
Deregulation of the electric power industry is making power quality a topic of increasing importance. Suitable corrective actions for the reduction of total harmonic distortion introduced into the distribution network by industrial loads are more necessary than ever. For the design of these corrective actions simulation has been proved to be a very useful tool. In this paper, the simulation of ...
متن کاملNumerical Model of Steel Slab Reheating in Pusher Furnaces
The difficulty in measuring load temperatures inside reheating gas furnaces may be circumvented by appropriate use of on-line numerical models. In this article we describe a model of pusher furnaces, used to reheat steel slabs. The model uses thermocouple measurements at fixed positions inside the furnace to calculate the temperature of the combustion products, and takes into account radiative ...
