LOD Furnace in Operation - invented by Shanghai Metallurgy Equipment Group

How Can LOD Furnace Upgrade Induction Furnace Steelmaking?

Introduction Induction furnace (IF) has been widely used in steelmaking due to its advantages of low investment, simple operation, and flexible production. However, traditional induction furnace steelmaking also has limitations. Because of its weak metallurgical refining ability, IF mainly focuses on melting and requires relatively high-quality scrap as raw material.…

What Is a Ladle Refining Furnace (LRF)? Equipment, Functions and Key Systems

In modern steelmaking, a Ladle Refining Furnace (LRF or LF Furnace) is one of the most important secondary metallurgy units. After molten steel leaves induction furnace or electric arc furnace, the LRF provides controlled heating, alloy adjustment, temperature control and argon stirring before continuous casting, helping produce cleaner steel with…

Steel Stirring Methods in Secondary Refining

Stirring is an essential operation in secondary steelmaking. By creating controlled circulation within molten steel, it improves heat and mass transfer, resulting in more uniform temperature, consistent chemical composition, and better steel cleanliness. Depending on the refining process, stirring can be achieved mechanically, by gravity, through gas injection, or by…

What Is Secondary Refining in Steelmaking? Key Functions of LRF in EAF and Induction Furnace Steel Plants

Secondary refining, also called ladle refining or ladle furnace refining, is an important process in modern steelmaking. After primary melting in an electric arc furnace (EAF) or induction furnace (IF), molten steel is transferred to a refining furnace for further treatment. The purpose of secondary refining is to improve steel…

What Is a Cooling Bed in Rolling Mills? Structure, Working Principle, and Stepping Rack Type Explained

What Is a Cooling Bed in a Rolling Mill? In hot rolling processes—whether in blooming mills or finished product rolling lines—rolled materials must undergo cooling, straightening, and finishing after deformation to ensure final product quality. A cooling bed is the equipment used to cool and simultaneously transport hot rolled products after rolling. Although…
