摘要

The process of dephosphorization of pig iron lu00ecquido, through the use of desfosforante agent injection micropulverizado deep and manufacture of their agents.The invention relates to the manufacture and use of an agent in the dephosphorization of pig iron desfosforante micropulverizado liquid in containers refractories in pots, with compositions defined after technical studies on the manufacturing system of the client and by injecting p Rofunda for refractory lance within the liquid metal with the inert gas of nitrogen or argon drag.Surface and blowing oxygen.The dephosphorization of pig iron with deep injection is governed basically by the kinetics of dephosphorization, which in turn is affected significantly by the particle size; therefore, the smaller particle size or smaller particle size the greater the contact area of the reaction. The greater efficiency of dephosphorization, and the oxidation of phosphorus.In combination with calcium and other components, which are injected in depth in the liquid metal to form compounds that are transferred to the slag, and thus removed from the metal.
