The activities of three common constituents of steel making slag viz FeO P 2 O 5 and Fe 2 O 3 were estimated using some of the commercially available thermodynamic packages which are based on different slag models The results were compared with experimentally measured values It was observed that the activities of FeO calculated using the package ThermoCalc were of the same order

The slagging process of molten steel is to control the type and quantity of slag material and add slagging agent so that slag has oxidation or reduction properties to meet the needs of the steelmaking reaction in the practice shows that slag making is an important means to realize the steelmaking process and making slag is a prerequisite for making steel

The three kinetic steps involved in the dissolution process are 1 diffusion of SiO 2 from bulk slag through a slag C 2 S boundary layer 2 diffusion of SiO 2 through the C 2 S layer and 3 interfacial reaction between solid CaO and SiO 2 at the interface between unreacted CaO and the solid C 2 S layer It should be pointed out that the assumptions used in this modeling work contradict

The characteristics of the slag hole are the shape of the hole is irregular and not smooth the whole or part of the hole is filled with slag The reasons for casting defects are insufficient purity of the molten iron poor slag removal and poor slag retention during pouring poor slag retention by the gating system and the gate is not full or cut during pouring

Slag is used in road making and as slag cement a finely ground slag which can be used in cement often mixed with Portland cement Cast iron The molten iron from the bottom of the furnace can be used as cast iron Cast iron is very runny when it is molten and doesn t shrink much when it solidifies It is therefore ideal for making castings hence its name However it is very impure
