Phosphorus Partition in an Industrial Basic Oxygen Furnace Process in Ukraine
steel research international, EarlyView.Phosphorus partition data from Ukrainian steel plants are analyzed, focusing on parameters like basicity, optical basicity, tapping temperature, and slag contents of FeO, MgO, and Al2O3. The analysis shows that phosphorus partition decreases with higher tapping temperatures and increases with optical basicity.

A Point Cloud-Based Method for Automatic Groove Detection and Trajectory Generation of Robotic Arc Welding Tasks [PDF]
arXiv, 2020 In this paper, in order to pursue high-efficiency robotic arc welding tasks, we propose a method based on point cloud acquired by an RGB-D sensor. The method consists of two parts: welding groove detection and 3D welding trajectory generation. The actual welding scene could be displayed in 3D point cloud format. Focusing on the geometric feature of the

Machine learning models for determination of weldbead shape parameters for gas metal arc welded T-joints -- A comparative study [PDF]
arXiv, 2022 The shape of a weld bead is critical in assessing the quality of the welded joint. In particular, this has a major impact in the accuracy of the results obtained from a numerical analysis. This study focuses on the statistical design techniques and the artificial neural networks, to predict the weld bead shape parameters of shielded Gas Metal Arc ...

Calculation of the equilibrium composition of metallic and oxide melts during their interaction [PDF]
The Seventeenth Israeli - Russian Bi-National Workshop 2018. The
optimization of composition, structure and properties of metals, oxides,
composites, nano and amorphous materials. Ariel, 2018, 262-272, 2018 Thermodynamic equilibrium can be sometimes reached at the interaction between metal and oxide melts in high temperature welding and metallurgical processes. Calculation of equilibrium phase composition is also one of the stages (along with kinetics analysis) of building an end-to-end physical and chemical model of real processes.
