EAF Electrode Arms are available in copper-steel composite arms and aluminum alloy arms.There are many advantages to using aluminum alloy conductive cross arms in a DC arc furnace.Due to the light weight of the aluminum alloy arm, the speed and control performance of the electrode lifting and lowering are further improved.Since the vibration attenuation can improve the stability of the arc and increase the arc power, this is the reason for choosing the aluminum alloy arm.

Electric arc furnace steelmaking is a steelmaking method that uses electric energy as a heat source.It’s an electric arc generated by the discharge between the electrode and the charge.Which converts the electrical energy into heat energy in the arc light, and heats and melts the metal charge and slag by the direct action of the arc radiation and the arc, and smelts a variety of qualified steels and alloys. A steel making method.

Electric Arc Furnace VS Ladle FurnaceAn electric arc furnace is an electric furnace that uses the high temperature generated by the electrode arc to smelt ore and metal. When gas discharge forms an arc, the energy is very concentrated, and the temperature of the arc area is above 3000 ℃. For smelting metal, the electric arc furnace is more flexible than other steel-making furnaces. It can effectively remove sulfur, phosphorus and other impurities. The furnace temperature is easy to control, and the equipment covers a small area. It is suitable for smelting high-quality alloy steel.

LF Ladle furnace steelmaking process is to put the molten steel in the final stage of oxidation in the converter or electric furnace, pour it into the LF furnace, remove 50-90% of the oxidized slag, and add reducing slag and deoxidizer for reduction refining.If the stirring time, slag amount, and stirring power under heating are appropriately increased, and the slag removal is 100% during tapping, the sulfur content in the steel can be further reduced, so that [%S] <30ppm and [%O] <20ppm, so that the molten steel can be reduced. become clean steel.

The design of submerged arc furnace is mainly used for reducing and smelting ores, carbonaceous reducing agents, solvents, and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicomanganese, and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide.

What is the difference between submerged arc furnace and electric arc furnace? An electric arc furnace is a kind of power-frequency electric furnace that uses electric arc energy to smelt metal. The electric arc furnaces used in industry can be divided into three types: the first type is the direct heating type. The electric arc occurs between the special electrode rod and the melted furnace charge. The furnace charge is directly heated by the electric arc, which is mainly used for steelmaking, and also used for smelting iron, copper,
