Oct 02, 2018· To improve the efficiency of melting modification for stainless steel (SS) slag, a shear force was introduced in this work and its effects on the spinel and silicate melt were experimentally investigated. The results indicated that the use of shear force changed the nucleation and growth behaviors of spinel and that the effects of shear force varied with its intensity.

Carlos Thomas, ... Francisco Agrela, in New Trends in Eco-efficient and Recycled Concrete, 2019. 7.1.2 Types and classification of steel slags. Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process.

This paper discussed the effects of B2O3 addition on the crystallization of Cr-bearing phase in synthetic stainless steel slag after different duration of molten slag at 1500 oC. The crystallized slag with or without B2O3 were then characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM) equipped with energy dispersive X-ray spectrometer (EDS) and electron probe ...

The slat cleaner can be used to remove slag in specific work areas or entire surfaces. Heavily soiled slats can be cleaned easily and efficiently, even stainless steel slag can be reliably removed in one simple procedure. The TruTool TSC 100 slat cleaner removes the accumulated slag on plasma tables that comes from production use.
AOD (Argon Oxygen Decarburization) slag is a by-product of the stainless steel refining process. The leaching toxicity of chromium from AOD slag cannot be ignored in the recycling process of the AOD slag. To assess the leaching toxicity of the AOD slag, batch leaching tests have been performed. PHREEQC simulations combined with FactSage were ...
Fuel element simulators of similar designs with inert aluminium matrix, in which UO2 was used in place of PuO2 were successfully in-pile tested under PWR conditions up to the burn up of 100 MW•d/kg U and fuel element simulators with inert zirconium matrix clad in stainless steel reached the burn-up of 200 MW•d/kgU with the temperature of ...

Sep 15, 2018· For the thermo-carbide slag pretreatment, 10.0 g dried energy plant sample was immersed in 200 ml 1.75% (w/v) carbide slag solution. The suspension was heated at 120 °C for 1 h in a sealed stainless-steel hydrothermal reaction kettle (Beijing Yanzheng Biotechnology co. LTD, Beijing, China) (Dien et al., 2006; Tao et al., 2018). After the ...
Sep 01, 2020· 1. Introduction. Stainless steels have a strict demand for the control of non-metallic inclusions to achieve a better surface quality .The composition, size, number, and distribution of inclusions have a great influence on the performance of stainless steels, .Especially, Al 2 O 3-rich or Al 2 O 3-MgO-rich inclusions led to linear defects on the surface of stainless steel products,,,, .
