Digital twin for bell-less top charging: accelerating blast furnace start-up and stability
Abstract
Blast furnaces are central to pig iron production, where efficient operation directly impacts productivity, hot metal quality, and overall cost-effectiveness.A key factor in this performance is the charging system, which significantly influences furnace stability.This paper presents the development of a Digital twin for a new bell-less top charging system.The solution integrates the Rockwell process control system with the Siemens SIMIT simulation platform and Primetals Level 2 and Expert system.This Digital twin was used for testing, training, and scenario evaluation, contributing to a rapid and stable blast furnace start-up following relining.
