identiﬁed this was achieved by comparing the effects on the ASR of replacing the FNS with sea sand and cement with ﬂy ash and ground granulated blast furnace slag (GGBFS). 2. Experiment Materials The FNS used in this study was obtained from SNNC Co. Ltd. a ferronickel manufacturer located in Gwangyang Jeollanamdo South Korea.

Oxidation roasting of vanadiumcontaining sludge with the additive led to an increase in the acidsoluble form of V2O5 from to and a decrease in the content of FeO∙V2O3 from 3 to . These results confirm the efficiency of the application of oxidation roasting to convert vanadium compounds into acidsoluble forms.
Various efforts are being made to use industrial wastes as an alternate moulding material in the foundry industry. Ferrochrome (FeCr) slag has many of the same attributes of sand. Hence in this paper investigations were carried out on the suitability of FeCr slag as mould material for either full or partial replacement of existing silica sand in the foundry industry. Owing to the
China Ferro Silicon manufacturer ferro manganese silicon. In the mean time we have several big factories for other ferro alloys production such as low carbon/Medium carbon ferro manganese and silicon manganese with the production capacity of MT per year. Our factory for calcium carbide located in Neimeng they′re
Feb 10 2021It was found that the reactivity of coke increased from to 81 after 15 FMG powder addition while the crushing strength (M 25) was decreased from 89 to 79 . When the addition amount of FMG powder reached 20 the reactivity of ferrocoke remained basically unchanged and the crushing strength (M 25) decreased to 58 .
Ferro chrome (FeCr) slag has many of the same attributes of the sand. In this paper investigations were carried out on comparative mould and casting properties of high silica sand and FeCr slag for foundry applications. A series of sand tests were carried out on silica sand FeCr slag individually and various combinations of these two.
200516 Virtually all charge chrome plants now use the crushing/jigging process to recover chrome alloy from both stockpiled and currently produced slag. Studies were carried out at RD Tata Steel to develop a flow sheet for the recovery of metal from metalslag mix generated in its charge chrome (ferrochrome with 5060 chromium) plant
effect of silica in ferro chrome slag crushing. ferro alloys like High Carbon Ferro Manganese and High Carbon Ferro Chrome nearly 800 kg. to 1200 kg of slag is produced per ton of ferro alloy and are tapped at temperatures of °C. In the production of Low Carbon Ferro Chrome upto about tons of slag is produced for each ton of L C
the right slag composition The slag composition is tested every day by sampling and analysis The typical ferrochrome slag composition is 30 SiO 2 26 Al 2O3 23 MgO and 2 CaO The chrome content in the slag is about 8 and the iron content 4 respectively Ferrochrome slag is acid Its basicity is 08 when it is calculated by .

These slags have found limited use as aggregate in road and civil engineering construction and in the production of refractories. However the content of the HCFeCr alloy in the majority of the ferrochrome slags is high enough that the alloy can be recovered profitably especially when cheap and environmentally friendly gravity based concentration methods are used to process the slags (Will and

Therefore it is very important to clarify the effect of binders and the large amount of iron ore on the quality of ferrocoke. In this paper the addition amount of iron ore powder (10 20 30 40 50 ) were used to reveal the effect of iron power amount on the crushing strength of ferrocoke. Then four types of binders (phenolic resin
Ferrochrome slag is a nonplastic material and absence of cement binder causes deficiency in hydrated phase formation which could be considered a major cause of strength degradation. Even the presence of microsilica and increased compactness owing to it could not make up for this deficiency.
