In this study the quaternary slag system CaO–Al 2 O 3 –SiO 2 –Na 2 O was investigated to determine the liquidus temperature and phase equilibria of slags relevant to e waste smelting The slags were thermally equilibrated at different temperatures inside a vertical tube furnace followed by rapid quenching
In order to study the effect of top slag with low basicity on transformation control of inclusions in spring steel deoxidized by Si and Mn the optimum composition of CaO–SiO 2 –Al 2 O 3 –MgO slag system with low basicity was firstly calculated by FactSage Then the industrial experiments were carried out based on the results of calculation
The results show MY can obviously increase the activity of slag powder 15 19 respectively at 7d and 28d JS can improve the output of slag grinding 10 by vertical mill The vertical mill grinding aids can significantly improve the activity and output of slag powder

Development of a mineralogy based anthropogenic combustion iron emission inventory Technical Report Rathod Sagar Bond Tami Atmospheric supply of iron can modulate ocean biogeochemistry due to its key role in global nitrogen and carbon cycles Using a detailed technology based methodology we revise total and soluble anthropogenic iron
The slag temperature drops with the slag thickness up to 60 mm beyond which the slag temperature rises The melt rate decreases and then increases while the cooling intensity remains unchanged As a consequence the maximal metal pool depth reduces from 0 081 m
The addition of 0 03 Nb produced poorer IC GC HAZ toughness data than C–Mn–V and C–Mn steels and this was related to the large size and area fraction of M A phase quantified in the Nb steel The presence of M A phase is considered to be the dominant factor in determining the toughness of IC GC HAZ View full abstract
A high speed steel composite roll billet was fabricated which is regular in shape smooth in surface slight in trace compact in internal structure free of slag inclusion shrinkage cavity cracks and other flaws and good in macro quality of junction surface using a vertical continuous casting machine The interface zone microstructure of bimetallic in billet of high speed steel composite

Metals an international peer reviewed Open Access journal Dear Colleagues Continuous casting is a process whereby molten metal is solidified into a semi finished billet bloom or slab for subsequent rolling in finishing mills it is the most frequently used process to cast not only steel but also aluminum and copper alloys
To avoid slag sticking onto the ladle snorkel during the CAS OB refining and alloying process CaO B2O3 and CaO CaF2 were respectively employed as modifiers added into the ladle slag The desulfurization capability of modified slag was investigated The results of experiments on sulphur partition equilibrium between metal and slag indicate that the sulphur content of metal can be further

The hydrogen reduction of Panzhihua ilmenite concentrate in the temperature range of 900–1050 C was systematically investigated by thermogravimetric analysis TG X ray diffraction XRD and scanning electron microscopy SEM methods It was shown that the products of the Panzhihua ilmenite reduced at 900 C were metallic iron and rutile
Abstract Ultrafine slag which is ground with the process of vertical mill is tested with the laser granulometric distribution apparatus quickly The characteristics of granulometric distribution of ultrafine slag are analyzed using fractal theory The fractal dimension of different fineness powders is
2 1 2 Preparation of wet grinded granulated blast furnace slag WGGBS In order to hinder self hydration of GGBS in the process of wet grinding and promote the grinding efficiency a polycarboxylate superplasticizer PCE 40 solid content was added WGGBS was prepared in a self made vertical stirred mill VSM The VSM included four specification spherical zirconia balls as
First the slag partially replaced 30 50 and 70 of Portland cement the strength reduced as the amount of slag increased however for high binder contents similar strengths were attained for
