As the snorkels are inserted, the NASH steam ejectors create a vacuum of 0.5 mm HgA and draw the steel into the chamber. The lower partial pressure within the vacuum chamber removes both hydrogen and nitrogen gases from the liquid steel, which are both vented as the steel is continuously circulated. The evacuation time is usually five minutes or less.
There are three basic types of vacuum degassers: steam, recirculation, and ladle. The system choice is determined by many factors, including the primary objective of the degassing capital investment costs, operating costs, temperature losses, tonnage, throughput, space availability, and turnaround time.
All types of systems take place in a vacuum chamber, and the vacuum is created by multis-stage NASH steam jet ejectors, often in combination with a NASH liquid ring vacuum pump.
Steam jets work on a constant mass flow basis, while liquid ring vacuum pumps work on a constant volume basis. Used together, an economic break-even point may be reached to take advantage of the best characteristics of each. Our degassing system is designed to meet specific requirements and your Nash engineer can help you determine the optimal solution. The steel degassing process requires:
