Blast furnace process tecscience

Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent.The carbon is fed to the blast furnace in the form of coke (pyrolyzed coal) from the coking plant.At sufficiently high temperatures, the carbon can participate directly in the


2018710&ensp·&enspHOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

Flow Patterns of Iron and Slag in the Blast Furnace Taphole

blast furnace (BF) since it ensures smooth operation which is a prerequisite of high productivity and long campaign life. The draining process is mainly driven by the infurnace overpressure that balances pressure drops induced by iron and slag flows in furnace hearth (i.e., through the dead man) and taphole.

Blast furnace for rolling mill machine is of great

Blast furnace for rolling mill machine is of great importance in steel rolling process. Blast furnace smelting is the continuous production process of reducing iron ore into pig iron. Solid raw materials such as iron ore, coke and flux are fed into the blast furnace in batches by

Flow Characteristics of Indian Blast Furnace Slag

2016530&ensp·&enspA study of the flow characteristics of Indian Blast furnace slag is necessary to study the softening and melting phenomenon in the blast furnace which highly affects the size and position of the cohesive zone. It also affects the operation in the blast furnace, hot

Top Gas Recycling Blast Furnace Process – IspatGuru

Top Gas Recycling Blast Furnace Process. In the area of production of hot metal (HM) by blast furnace (BF), the most promising technology to significantly reduce the CO2 (carbon dioxide) emission is recycling of CO (carbon mono oxide) and H2 (hydrogen) from the gas leaving the BF top.

A Study of the Heat Flow in the Blast Furnace Hearth Lining

201076&ensp·&enspThe blast furnace is an ironmaking process with a long history: the oldest known blast furnace in Sweden can be dated to the 12 th century. Research and engineering efforts to improve the process have presumably been going on since the first furnace was built. That has contributed to the fact that the blast furnace has maintained its unchallenged

Developments of the ULCOS Low CO2 Blast Furnace Process

It was possible to operate the blast furnace process and the gas separation plant VPSA in a closed loop. The obtained Csavings were consistent with the predictions from the flow sheet calculations. The tests also indied that conventional burden material sinter, pellet and coke can be used for the ULCOS blast furnace process.
