What are the main parts of electric arc furnace?


The main mechanical equipment of electric arc furnace is composed of metal parts of furnace body, electrode seat and electrode lifting device, furnace body tilting device, furnace cover lifting and rotating device, etc.


Furnace body is a very important equipment in electric furnace. It is mainly used to melt furnace charge and carry out various metallurgical reactions. The furnace body of electric arc furnace is composed of metal components and refractory lining. The metal parts of the furnace body include furnace shell, furnace door, tapping groove, furnace cover ring and electrode sealing ring. The furnace shell is welded with steel plate, and the upper part of the furnace shell is provided with a reinforcing ring. The upper part of the large furnace shell is often made into two layers, with water cooling in the middle. The furnace door is used to observe the situation in the furnace, as well as slag scraping, sampling, charging and other operations. The furnace door is usually covered with a furnace door cover. The furnace door is usually cooled with water.


The door cover of small electric furnace is opened and closed manually, while the larger electric furnace is opened and closed by compressed air or hydraulic mechanism. The tapping trough is connected with the furnace shell, the outer side is welded with steel plate, and the inner side is built with refractory. Around the furnace cover of electric arc furnace is an annular member welded by steel plate or section steel, which is called furnace cover ring, and most of it is cooled with water. The furnace cover is arched with refractory. There are three electrode holes symmetrically arranged in an equilateral triangle on the furnace cover, and there is an electrode sealing ring between the electrode hole and the electrode. The electrode sealing ring is made of steel plate and cooled with water.


In the process of electric arc furnace steelmaking, due to the continuous melting of furnace charge, different electric energy needs to be supplied in each melting stage, and the electrode needs to rise and fall at any time to ensure or adjust the arc length. Structure: there are two types: movable column type and fixed column type. Large electric furnaces generally adopt movable column structure.


Well, the above is a brief introduction to the main components of the electric arc furnace. For more information about the electric arc furnace, please pay attention to the official website: http://lvshenyouji.com/
