Stainless steel slag fundamentals: from furnace to tundish ...

Slag practices and conditions that are optimal for stainless steel quality and good refractory performance are defined. Phase equilibria and computer modelling are used to simulate and predict refractory–slag and slag–metal interactions. The slag principles and requirements for ing in the electric arc furnace are discussed.

Stainless Steel Slag is processed and sized at the TMS Calvert, AL, facility where it is engineered to meet all market specifications and is structurally stable. The material represents a practical resource that is both economically attractive and environmentally sound. TMS INTERNATIONAL STAINLESS STEEL SLAG IS A STABLE, SUSTAINABLE PRODUCT

Steel Slag - Material Description - User Guidelines for ...

The steel slag produced during the primary stage of steel production is referred to as furnace slag or tap slag. This is the major source of steel slag aggregate. After being tapped from the furnace, the molten steel is transferred in a ladle for further refining to remove additional impurities still contained within the steel.

Stabilization of Stainless Steel Slag via Air Granulation ...

In stainless steel production, slag from argon oxygen decarburization (AOD) converters is dumped on to the ground and then slowly cooled. The slag undergoes phase transformation from β-dicalcium silicate (β-C 2 S) to γ-dicalcium silicate (γ-C 2 S) at approximately 500 °C to 450 °C, resulting in slag volume expansion, disintegration, and dust generation.

Use of stainless steel slag as aggregate in concrete

Stainless steel slag with a basicity of over 1. 5 disintegrated into fine particles during cooling. Such disintegration was liable to cause environmental problems and disturbed further utilization ...

CHEMISTRY, MINERALOGY AND MORPHOLOGY OF STEEL …

Portland cement, GGBS, steel slag and stainless steel slag as reported in different literatures. Compare to the oxide composition of OPC and GGBS, steel and stainless steel slags generally contain less lime (CaO), silica (SiO 2) and alumina (Al 2O 3), but contain more quantities of ferric oxides (Fe 2O 3) that cannot be

Effect of stainless steel slag waste as a replacement for ...

The application of stainless steel slag waste reduces the use of raw materials for manufacturing cement and provides a profit from the large amount of waste generated. This study analyses the cementation and pozzolanic reaction characteristics of stainless steel slag waste to evaluate its strength activity index and its environmental impact.

Potential of Stainless Steel Slag Waste in Manufacturing ...

The stainless steel slag (SSs) come from the company Acerinox Europa S.A.U. located in Los Barrios (Cádiz), Spain. The SSs were processed in the laboratory, obtaining four different materials to be used in the manufacture of SCC (Figure 2): SSs (stainless steel slag dried in an oven for 24 h and screened with a

Performance of Stainless Steel Slag in Concrete Structures

Stainless Steel Slag on various proportions in Concrete (25% 50% 75% ). The basic objective of this study was to identify alternative source of aggregates and cement and to produce new type of concrete made of stainless steel slag as a green concrete. And to control the manufacturing

Processing fine stainless-steel slag using spiral ...

Processing fine stainless-steel slag using spiral concentration. Wolfe ER(1), Klima MS. Author information: (1)Energy and Mineral Engineering, The Pennsylvania State University, University Park, Pennsylvania, USA. In this study, the effectiveness of spiral concentration to process a fine (-1 mm) stainless-steel slag was evaluated.

Solidification of stainless steel slag by accelerated ...

As molten stainless steel slag containing dicalcium silicate (C2S) cools it can undergo several phase transitions. The final transformation from the beta-polymorph to gamma-C2S is accompanied by a volume change that causes the slag to self-pulverise or 'dust'. As a consequence of this the fine grained portion of the slag contains more of this ...
