What are the measures to improve the life of the electric arc furnace body?
In view of the phenomenon that the SiO2 content in the slag during the melting period is relatively high and the alkalinity is low, some measures can be taken, for example, adding light magnesia powder to the furnace before melting and adding lime to the furnace when adding surplus material in the melting period, to increase the content of MgO and the concentration of CaO in slag, reduce the combination of Si02 and MgO, and ensure that there are enough CaO and Si02 phases in slag, so that they can achieve the purpose of protecting the lining refractory bricks.
When the MgO content in the slag is raised again above 1500℃, the carbon element in the refractory bricks and the ferrous oxide in the slag will react with MgO as follows:
MgO+C→Mg (gas)+CO
2FeO+C→2Fe+C02
Mg (gas) + CO2 → MgO + CO
Mg (gas) + FeO → MgO + Fe
