New carbon agent in cast iron roll on the application
Ways for high capacity carbon-frequency electric furnace is more effective. This way by adding a new agent a 2 carbon carbon effect as shown in Table 7, the average carbon sequestration rate of 87.9%. Added to the bath with carbon agent, only in the hot liquid iron to be very good when the absorption of 1400-1500 ℃. With the solid charge into the furnace, the agent also in charge carbon and heat to melt when the temperature can be absorbed. Carburant absorption time and silicon content in liquid iron is related with the improvement and extension of silicon content. When the molten iron needs while adding agents and increasing carbon silicon agent (ferrosilicon), you must complete in order to add carbon Table 6 dim yi} -2 Pa stack stupid twitter heading Gao Tab.

Iron}. Bo o seek stern mouth cleOf added by silicon agent (ferrosilicon), so as not to affect the rate of increase in carbon. When using the oxidation of a serious charge, such as iron or steel with a rusted scrap melting, the liquid added to the molten pool occurs carburant strong ferrous oxide reduction reaction: FeO + C = Fe + COT because the oxidation of carbon , carbon absorbed in the low, the same time, the escape of carbon monoxide gas from the furnace to make molten iron ejected. Carbon absorbed in the rate of oxidation of added methods and the degree of charge. Generally believed that the increase in carbon on the bath surface agent, its absorption into the higher rate than with the charge of about 1O%,[link widoczny dla zalogowanych], because the slag removed after the oxide, carbon is not consumed in the oxide reduction agent. Although the carbon added to the bath surface can be less dosage, but in general, or by way of loading the furnace, so that you can reduce the burden in addition to burning, they can also ensure safe operation. Glass carbon electrode Gap speed, temperature of molten iron reaches 140O ~ 1470 ℃ per minute 0.12%. Because the carbon dissolved in liquid iron in the reaction is endothermic reaction,[link widoczny dla zalogowanych], therefore, generally the 1450c as the lowest carbon liquid iron temperature. Lower the temperature of molten iron, carbon speed is reduced. 4 Conclusion (1) a 2 carburant, high carbon content, density, low ash and sulfur containing more easily absorbed by the molten iron,[link widoczny dla zalogowanych], carbon sequestration agent was 90%,[link widoczny dla zalogowanych], is a high quality carbon agent . (2) carbon steel charge both agents and loaded, carbon efficiency, increasing carbon stability. References [1】 Like Shi induction furnace melting of cast iron [M】.
