Transportation of Liquid Slag in Cast Iron Slag Bowls

The paper considers the transportation of liquid blast furnace slag in slag bowls made of blast furnace, cast iron. The cast-iron slag bowls are made to have high operational resistance. The article proposes technologies for modifying cast iron by pulsating purging and micro alloying with titanium and vanadium. The research proposes new time limits for modeling of the rail transportation of molten slag. The authors offer a model describing the maximum length of movement of molten slag. They also introduce a new model to determine the optimization criterion. The paper also considers the applicability of different types of lubricants for the operation of slag trucks. It has found that it is possible to apply blast furnace cast iron, which is for casting the slag bowls. It is advisable to use purging of cast iron with nitrogen and micro alloying of cast iron with titanium and vanadium in order to improve its properties. Mathematical modeling makes it possible to evaluate the optimal operating mode of slag bowls. The existing lubricants provide regular operation of the bowls.
