Electric arc furnace is a commonly used smelting equipment used to heat and melt scrap steel or iron ore, and manufacture steel tanks. The working principle of an electric arc furnace is to use the high temperature of the arc to heat and melt metal materials. Now let's learn about the process of how an electric arc furnace takes out a steel groove.
Firstly, we need to prepare scrap steel or iron ore. These raw materials are placed in the hopper of the electric arc furnace for use in the subsequent smelting process. At the same time, it is necessary to prepare electrodes and power sources to power the arc furnace to generate high-temperature arcs.
When everything is ready, we open the hopper of the electric arc furnace and pour scrap steel or iron ore into the furnace chamber. Then, bring the electrode closer to the raw material to generate an arc. The high temperature of the arc heats and melts the raw materials, forming molten metal.
Next, we need to control the temperature and other parameters of the electric arc furnace to ensure the smooth progress of the metal smelting process. By adjusting the intensity and position of the arc, we can control the melting rate and temperature of the metal. In addition, an appropriate amount of auxiliary agents such as limestone can be added to the furnace to adjust the composition and properties of the metal.
As smelting proceeds, the metal will gradually melt, forming a liquid steel liquid. At this point, we need to open the steel outlet at the bottom of the furnace chamber to allow the steel liquid to flow out. Due to the high density of the molten steel, it will naturally flow from the furnace chamber to the outlet groove, forming the molten steel in the groove.
In order to ensure the quality and uniformity of the steel liquid, we also need to stir and remove slag from the steel liquid. By injecting argon gas into the steel liquid or stirring through mechanical devices, impurities and bubbles in the steel liquid can float to the surface and be discharged through the slag outlet of the steel tank.
Finally, when the molten steel has completely flowed out, we can close the tapping tank and complete the tapping process of the electric arc furnace. At this point, the molten steel will cool and solidify in the tapping tank, forming steel billets or other required steel.
During the process of electric arc furnace tapping, it is necessary to control parameters such as temperature, arc strength, raw material composition, and stirring to ensure that the quality and composition of the steel liquid meet the requirements. At the same time, safety measures need to be taken to prevent explosions and other accidents in the electric arc furnace.
In summary, the tapping groove of an electric arc furnace is a complex and precise process. By controlling various parameters, we can heat and melt scrap steel or iron ore to produce high-quality steel tanks. Electric arc furnaces not only effectively utilize scrap steel resources, but also produce steel that meets the requirements, which is of great significance for the development of the steel industry.
