Abstract

In the initial stage, as well as today, physical models are frequently applied for 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 describes the methodologies developed at LaSiP (Simulation Processes Laboratory) to measure and define mixing time using at same time two different techniques: conductivity meter and lucimetry using a mixer of tracing: KCl and KMnO4.
