In addition to coke fines, the flue dust also contains fines generated from BOF slag, limestone and pellets, and as a result it contains basic oxides such as CaO and MgOas well as a considerably high amount of Fe 2O 3. In several studies on injection of fluxes and iron ore, the effect on hot metal composition has been considered.

Abstract The initial study to control the coal rate injected into a slag-cleaning furnace (SCF), based on a soft sensor, was developed at Caletones Smelter, Chile. The old estimation algorithms were only based on discharged cycle average information, leading to large prediction errors. In this paper an improved estimation of the current coal rate is presented, based on valve positions and ...

09-10-2018· In the slag-cleaning process considered here, the furnace would be operated with a layer of electrically conductive coke or coal covering the slag. As the electrodes of the AC furnace penetrate this layer, there exists the possibility of the current flowing between the electrodes on the surface of the slag. The gas injection of solid .

2.1 Carbon Injection into EAF slags In modern EAF steelmaking, carbon in the form of coke, char or coal, is injected into the furnace and reacts with slags (FeO/Fe 2O 3, CaO, MgO etc.) and post-combustion gas (CO 2). Those reactions produce gas, which causes the slag …
13-08-2012· One never knows what sort of gunk they are placing into their system. Cocaine is soluble as 1g : .5ml water. A good solution would be to clean their street cocaine either by acetone wash or better by alcohol recrystallization. This will eliminate most of the inactive adulterants in the street cocaine and make for a cleaner injection.
slag cleaning processes3·8, with one of the most effective methods being the injection of gaseous or solid reductants into the molten slag bath.
