【 摘 要 】

The article present the developed method for production of pig iron with a very low titanium content of Ti < 0,02 %, while taking into account specific charge conditions. A two-week preliminary pig iron production test carried out determined the direction in managing two technological indicators, namely pig iron [Si] content and slag (CaO/SiO₂) basicity, to obtain pig iron with a [Ti] content below 0,02 %. Based on the data from the preliminary test, proper tests were carried out with a pig iron Si content in the range from 1,0 % to 1,6 % and a slag CaO/SiO₂ basicity in the range from 0,96 to 1,10. Data obtained from those tests enabled a statistical model to be established in the form of regression planes of two independent variables, [Si] and (CaO/SiO₂). The regression equation of the first degree, [Ti] = f[(Si), (CaO/SiO₂)], defined the plane that gave the process engineer the answer to the question of how to manage the [Si] and (CaO/SiO₂) indicators so as to obtain pig iron with the desired [Ti] content below 0,02 %.
