What are the factors that affect the service life of electric arc furnaces?
Every transaction has a lifespan, usually in order to make our=“ http://www.ayynd.com/product What are the factors that affect the lifespan of electric arc furnaces, as we need to do a lot of work for them to last longer? We can consult with the electric arc furnace manufacturer Youneng De!
1. Influence of high temperature thermal effect
Smelting temperature is generally above 1600, which has a significant impact on furnace age. In addition, due to the design of the first and second furnaces, the furnace lining needs to withstand rapid heating and cooling. This phenomenon is inevitable in the smelting process, but it is necessary to minimize or reduce the degree and time of high-temperature heat effects as much as possible, including rapid melting and charging, ensuring the normal operation of equipment, and minimizing downtime to the greatest extent possible.
2、 The influence of chemical erosion
During the steelmaking process, various chemical reactions are constantly occurring, especially at the slag steel interface where they are more intense. The refractory material of the furnace lining is prone to peeling off under the action of chemical reactions. Chemical erosion is related to the composition and flowability of slag. When the content of acidic or slightly acidic oxides such as SiO2, P2O5, Al2O3, or Fe2O3 in the slag is high, MgO is prone to react and form magnesium silicate and magnesium aluminate. The influence of slag fluidity on chemical erosion is mainly due to the low alkalinity of dilute slag, severe chemical reactions, rolling of molten slurry, and easy increase of furnace lining heat load. Thick slag is difficult to heat in the melting pool, requiring an extended high-temperature smelting time to promote damage to the furnace lining. In addition, there are many factors that can affect the lifespan of an electric arc furnace. We will not introduce them one by one here.
