Measurements methodologies for basic oxygen furnace cold modeling

Abstract

In the initial stage, as well as today, physical models are frequently applied for basic oxygen furnace (BOF) process development. BOF cold model simulations have as fundament the geometric, kinematic, and dynamic similarity. The dimensionless numbers warranty the similarity. Based on the similarity criteria, it is possible to transpose the laboratory results for the industry. Develop the right methodology to get precise measurements of proposed experiments is a critical step in cold modeling. Due to different characteristics available regarding cold modeling, the work summarized in this paper offer a literature review centered in measurements methodologies for BOF cold modeling and describes the methodologies developed at Processes Simulation Laboratory (LaSiP) to measure and define mixing time, mass transfer, jet penetration, decarburization area, slopping and projection rate on cold models.
