| Summary |
|---|
| The subject is focused on the application of theoretical knowledge to the student technology training blast furnace charge and the production of pig iron in a blast furnace. It deals with the management of productivity agglomeration equipment, blast furnaces, sinter produced quality management and pig iron. Are analyzed technological disturbances in the production of pig iron and technical-economic indicators of the work of the blast furnace. They are described and analyzed various technological nodes blast furnace operation, methods of lining and cooling a blast furnace, hot blast of wind and discharge of liquid products was carried. They also assessed the environmental aspects of the production of pig iron. |
