What are the factors affecting the service life of electric arc furnace?


Any business has a service life. Usually, we need to do a lot of work in order to make our electric arc furnace longer. What are the factors affecting the service life of electric arc furnace? We can consult the electric arc furnace manufacturer younengde!

1. Influence of high temperature thermal effect


The smelting temperature is generally above 1600, which has a great impact on the furnace life. In addition, due to the design mode of the first and second furnaces, the furnace lining has to withstand rapid cooling and heat. This phenomenon is inevitable in the smelting process, but the degree and time of high-temperature thermal action must be reduced or reduced as much as possible, including rapid melting furnace and charging, ensuring normal operation of equipment, reducing shutdown time to a greater extent, etc.


2. Effect of chemical erosion


In the process of steelmaking, various chemical reactions are always going on, especially at the slag steel interface. The lining refractory is easy to peel off under the action of chemical reaction.


Chemical erosion is related to the composition and fluidity of slag. When the content of acidic or partial acidic oxides such as SiO2, P2O5, Al2O3 or Fe2O3 in the slag is high, MgO is easy to react to form magnesium silicate and magnesium aluminate. The influence of slag fluidity on chemical erosion is mainly due to low alkalinity of thin slag, serious chemical reaction and tumbling of molten slurry, which is easy to increase the heat load of furnace lining. It is difficult to heat the melting pool with thick slag, so it is necessary to prolong the high-temperature smelting time and promote the damage of furnace lining.


In addition, there are many factors that will affect the service life of the electric arc furnace. Here we will not introduce them one by one. If you want to know more about the electric arc furnace, please pay attention to the official website: http://www.ayynd.com/
