AISI/DOE Advanced Process Control Program Vol.2 of 6: Improved Liquid Steel Feeding System for Slab Casters

摘要

This report describes the development, construction and testing of the Electromagnetic Valve System (EVS), conducted as a project entitled 'Improved Liquid Steel Feeding System for Slab Casters'. This program ran from November 1992 to January 1995. Many of the technical issues in bringing the EVS to the steel industry were identified and resolved during the course of the program. During this time, significant hardware improvements in Westinghouse's electromagnetic valve were made to easily integrate it with existing continuous casting processes. An improved refractory nozzle was developed and tested which had superior thermal shock and anti-cracking performance. In addition, several trials were conducted with molten steel to verify the proof-of-principle of the electromagnetic valve and its auxiliary equipment. However, improvements in other conventional pouring technologies have greatly diminished the potential value of this project to the steel industry.
