Calculating Model for Nitriding and Denitriding of Stainless Steel 304 in AOD Refining and Its Application

The control systems both at home and abroad for the AOD refining process of stainless steel were reviewed and the characteristics of the systems were introduced in detail.

The article describes the technology characteristics of AOD refining duplex stainless steel,two tons AOD refining furnace refining 00Cr22Ni5Mo3N duplex stainless steel practice,refining a alloy steel and pouring a chemical box runner fans,the mechanical properties and microstructure of casting is in compliance with the technical requirements.

This paper sums up the construction techniques of automatic instruments in feeding system of stainless steel-making,including some typical instruments such as the capacitive level gage,the guided-wave radar level gage,and weighting sensor,etc.

This paper expounds the factory manufacturing in and field installation of enclosed room of oversized converter in 150 tons stainless steel making engineering of Taiyuan Iron and Steel Complex.

The modern stainless steel plant,which is a place integrating the equipment,technology,material flow and information flow,must have perfect MES to carry on the whole process management for achieving the purpose of prompt,high-effect,economic,stable and flexible production.
