Manufacture of the Titan
Manufacture of the titan is the huge industrial enterprises where each shop represents almost the whole independent factory. "Birth" of the titan is preceded with some stages, so-called limits, each of which - the certain technological stage. Regenerative the ilmenit concentrate by melting - the first stage of processing of raw material at combine. In the usual electroarc furnaces representing baths from a fire-resistant brick with lowered almost up to bottom graphite by electrodes, load shihtar. It consists from the ilmenit concentrate and a special carbonaceous reducer - coke, anthracite and others carbon containing substances with the least quantity of ashes and sulfur. As a result swimming trunks receive slags rich with the titan and usual pig-iron. Presence at pig-iron of the titan operates salutarily on ferrous metal, therefore by manufacture of pig-iron and steel the titan to them quite often add specially. Here the titan passes in pig-iron directly from the ilmenit concentrate. A part oxidize of ilmenit iron it is restored up to metal which falls on a bottom of a bath and, being sated with carbon, turns to pig-iron. To separate titanic slags from pig-iron, to liquid weight allow to be defended. Titanic slags emerge, and heavier pig-iron settles on a bottom. The basis of slag is made with dioxide of the titan, but it is polluted by impurity of connections of iron, silicon, calcium. The cooled down slag represents a powder in which are clearly visible fine scales . In titanic slag add oil coke. As connect substances apply coal baked or pitch. From the received weight named of shihtar, press briquettes. Them dry up, then in special furnaces where air does not get, to connect together at 700 900 C . As a result there is a process of coking, times in briquettes increase. Already it is possible to submit briquettes to the mine furnace. The furnace for chlorination is the steel cylinder which has been laid out from within by a layer of especially proof brick. In the cylinder through the loading device briquettes of shihtar from above get, by means of electroheating elements lead up their temperature up to 800 850 C. Chlorine submit from below. The furnace hermetically is closed and works continuously. Processes of chlorination go in bottom, heat up a layer of shihtar. In process of an expenditure of briquettes add new, and load them so, that tightness of the furnace is not broken.
