Studying and improving blast furnace cast iron quality

In the article there are presented the results of studies to improve the quality of blast furnace cast iron. It was established that using fire clay suspension for increasing the mould covering heat conductivity improves significantly pig iron salable condition and filtration refining method decreases iron contamination by nonmetallic inclusions by 50 – 70 %

Studying properties of carbonaceous reducers and process of forming primary titanium slags

When smelting a rich titanium slag the most suitable are low-ash reducers, and the studies revealed the suitability for this purpose of special coke and coal. An important property of a reducer is its specific resistance. Therefore there were carried out studies for measuring electric resistance of briquettes consisting of ilmenite concentrate and different carbonaceous reducers. It is recommended to jointly smelt the briquetted and powdered burden (the amount of the powdered burden varies form 20 tо 50 %), this leads to the increase of technical-economic indicators of the process

О ТРАНСПОРТНЫХ КОРИДОРАХ КАЗАХСТАНА

The authors study further developments of transport corridors of the Republic of Kazakhstan, analyze the fulfilled works, existing routes, and the problems to solve in future. Six motor road and six railway corridors under consideration are presumed objects for optimization engineering.Перспективы развития транспортных  коридоров Республики Казахстан.  Анализ выполненных работ,  существующие магистрали  и проблемы, которые предстоит  решать в будущем. Каждый  из шести железнодорожных  и шести автомобильных коридоров,  ставших объектами внимания  исследователей, дает повод искать  для себя варианты оптимизации
