Simulation Tool Using Blast Furnace Rist Model

"Simulation tool based on a Rist model provides quantitative support for understanding the current condition of operation, and for operation design for improvement, by enabling simple calculation of the mass and heat balance in the blast furnace. "

Solution Point

Blast furnace operational parameters related to mass and heat are visualized by a Rist model. Not only supports understanding of the current condition, but also provides quantitative support for operation design to achieve designated targets.
Speeds up the PDCA cycle for improvement actions and also prevent operational trouble due to inappropriate operation design by simulation using this model before applying proposed improvements to the actual operation.

Features 01

Expected Problems

・We want to implement operational improvements such as reduction of reducing agent ratio and increased production, but we don't know how to change operating conditions to realize improvements.

Features 02

Technology highlight

Development of a tool that enables simple calculation of the heat/mass balance of the blast furnace based on a Rist model.

Supports understanding of the current condition of the BF by outputting the Rist operation diagram and main operational parameters when operating conditions (raw materials, blast, etc.) are input.

In the operation design mode, supports operation design by outputting the operating conditions for achieving the target parameters when the parameters to be realized are input.

Features 03

Proposed Solutions (Examples)

"Model has been applied to all blast furnaces in JFE Steel, and is now being used to understand the current condition and in operation design. *We can also consult with Clients regarding shaft furnaces other than the blast furnace."
